exFat VSN volume serial number

[Scott Lurndal]

Anyone know of a free reliable Win10 exFAT serial number changer?

I already tried the sysinternals volumeid which doesn't work on exFAt
https://docs.microsoft.com/en-gb/sysinternals/downloads/volumeid

I formatted the 64GB sdcard as exFAT with a volume label (Volume Name) of my
choosing (eg /storage/sdcard1) but some file managers require the volume
serial number instead (/storage/FFFF-FFFF) which is essentially random and
as such is something you always have to write down (as the 8 hex characters
are only a function of the time & data when formatted).
https://www.wintips.org/how-to-change-hard-disks-volume-serial-number-volume-id/

Hard Disk serial number change also won't work on exFAT systems
https://hard-disk-serial-number-changer.en.softonic.com/

Do you know of a reliable free Windows 10 exFAT file system VSN changer?

I am not a Windows user any more but this chap reckons you can do that
with the built-in application "diskpart".

I wonder why they called it a "signature" but not a "volume serial number"
which is (AFAIK) the correct technical term for the 8 hex digits on exFAT.
https://www.howtohaven.com/system/change-disk-signature.shtml

I wonder if they're talking about the MBR "signature" instead?
Dunno.

But I tried it and it failed but it was a good approach to test out.

DiskPart has encountered an error:

I'm not sure why it shows up as "00000000" when it shows up in the phone
as "C64B-FE9D" (which Windows 10 created at the time of exFAT formatting).

I tried this ghacks method but predictably it failed because "Hard Disk
Serial Number Cahnger" only supports FAT, FAT32, and NTFS file systems.
https://www.ghacks.net/2009/04/22/hard-disk-serial-number-changer/

Most automatic VSN editors don't work on exFAT and manual HxD methods
require calculating the correct checksum which has to be done manually.
https://twlee.nz/changing-exfat-volume-serial-number/

The "AOMEI Partition Assistant Pro" payware apparently changes exFAT VSNs
as does "Paragon Hard Disk Manager 16 Advanced" payware according to this
https://gist.github.com/dreamer2908/59066658df2844746e5feadba7a589a2

That explanation suggests using HxD to modify Krylack but it failed to work
https://www.krylack.com/volume-serial-number-editor/

The comments in that explanation suggest using the DiskGenius freeware
https://www.diskgenius.com/

It shows a "MBR Signature/Disk GUID" of "F6B30727" which I don't recognize.

The closest thing I could find is the command "Open Hex Sector Editor"
but I didn't know what to do with it so I closed that down without changes.

At this point I'm still stuck without a freeware exFAT VSN editor to change
...from a hard to remember Volume Serial Number (VSR) of "C64B-FE9D"
...to an easier to remember (and to type) VSR of "BEEF-CAFE" (or whatever)

The ones for Windows I know of, are either entirely not free or (like
Minitool Partition Manager) do not support this functionality in their
free versions:

www.minitool.com/partition-manager/partition-software-comparison.html

If Linux would be okay, as well, then have a look at exfatprogs:

https://github.com/exfatprogs/exfatprogs

Changing VolumeSerialNumber is a recent addition to exfatlabel (-i switch)
and (according to user reports) works well.

Generally spoken, changing the serial number isn't too hard and could be
done with any disk editor. It's just the volume checksum, that also needs
to be adjusted. That's more complicated. Because exfatlabel contained the
checksum adjustment, anyway, the serial number adjustment working from
scratch correctly should be no surprise. Just be sure to pass the new
serial as hex value without dash to the exfatlabel -i parameter.

HTH.

Not sure if this will work, try to boot a live Linux and use GParted
and see if that works

This is NOT an easy question to answer.

Thanks to all for taking a stab at this freeware question given I doubt it
has ever been asked on this newsgroup before.

It may very well be that there is no dedicated exFAT VSN editor on Win10.
But I'm still hoping I can find a free Windows program that sets the VSN.

I don't have Linux but I'm also told that mkfs.exfat should work (which may
be similar to your exfatlabel hint and Nic's GPartEd Linux suggestions).

But I'm seeking Windows freeware to do the task.

The problem set is seemingly so common that one would think a freeware
solution exists in that there are no downsides & the advantages are
(1) Hot swapping inside Android works better with apps needing the VSN
(2) Typing paths inside Android works better with easily remembered VSNs

I've scoured the first few pages of duckduckgo & google search results to no
avail other than using HxD to manually edit the volume serial number.
https://twlee.nz/changing-exfat-volume-serial-number/

That solution requires computing the checksum using a python script
exfat_bootsector_checksum.py

Which requires installing a python interpreter on Windows & running the pgm
https://gist.github.com/twlee79/81f1b8f62246952c2efaaf5935058ce6

I may be able to manually calculate the checksum outside of python though
https://www.digital-detective.net/documents/Volume%20Serial%20Numbers.pdf
https://www.sans.org/reading-room/whitepapers/forensics/reverse-engineering-microsoft-exfat-file-system-33274

But before I go either of those routes I'm still hoping for a working
freeware sdcard exFAT volume serial number editor/changer on Windows 10.

I don't think the free edition allows you to set hard drive
parameters or even edit the disk. I might be wrong though.

I've been through and done with those links for a while now, as I wouldn't
have bothered to ask the question if I could find the answer in a search.

Nobody is going to find the answer by telling me their search results.

Unless people use a different search engine than DuckduckGo and Google (yes,
I had to use Google too because I haven't found the answer yet anywhere), or
if they use very different search terms than I used, they're not going to
find any solution to the problem set in a search that I haven't already run.

As I already mentioned, DiskGenius didn't do anything (it reported a VSN of
00000000 instead of "C64B-FE9D" (which Windows 10 created at the time of
exFAT formatting).

If anyone's search produces these links - I've already been through them.

It's to the point where a disk drive is sold with qualification --
Works on Windows 10.

Nevermind a everything preceding, which HDDs would most not be
precluded by dint and from their engineering and longest
implementation. It's the solidstate drive, in its many flavors from
first PATA/SATA to slotted, and offset of micro-slotted memory that
emulates the former yet is designed for limited firmware operability
devices (cameras or music players) and operation systems AMR/RISC
storage consideration.

There's nothing short of a USB adapter for a micro-SD card in a PC
capacity. Bearing that in mind, further if not with any mention of
2.5 SATA drive SSD products, I once ran into a problem with a
microcard. What that was the merchant sent me two free 64G,
micro-device storage replacements, which I then effectively bricked.

Turns out the USB adapter was out of date and a newer replacement
inexpensive. There's also the personal computer OS, which needs to
support the USB micro-memory storage device. I was able to reformat
and regain one of the formerly bricked devices, the other remains
bricked.

I also have a 64G 2.5 SATA SSD, one of the earliest solidstate
contenders against the plattered mechanical drive. It's the closest
SSD around that duplicates in all ways a traditional legacy (or
otherwise) BIOS expectancy of mechanical storage considerations. I
shouldn't necessarily expect that, backwards disc program
compatibility, with all the many brands and use of proprietary
controllers across solidstate drives.

Last to use them in the same sense on mini-cards for Lollipop
operating system with yet another layering apart from the PC SSD
device (TRIM, for instance, a mini-disc is running its own controller
checksum implementations).

Bricking micro-card "drives", although I've only one to my credit, I
could even begin to say how easily accomplished over, say, the PC
counterpart. I did, however, wear down my favorite USB flashstick,
and, for my money, bought a $3/US Hong Kong gizmo with two power/data
cable ports for converting a SSD into a traditional USB flashstick. An
upcoming deal on a PC SATA SSD, I expect, should beat a microcard and
adapter in all kinds of ways.

(Although I can access and manipulate a micro Droid-mounted storage
card, either through a USB to PC connect, able then to "see" the
microcard from the PC, if not as well from a freeware APK file manager
running from mounted storage on the tablet itself. Firmware
proprietary to my device -- not all devices may indeed exhibit
cross-interoperability.)

Sad days, should a microcard cost as much as a PC SATA SSD. Sadder
yet, brick the former (I've yet to brick my first SATA SSD). I talked
to Sandisc, a subsidiary of Western Digital, making microstorage for
telehandphones. Mileage varies, although I'm in no hurry to load up
on another MicroSD card anytime soon.

e.g - two being an implementation or variation upon USB3 and USB2,
which are running different voltages;- not all USB3 to 2.5 SSD
single-port converters adapt to a USB2 slot. I'm nominating it for the

I would look again at the krylack.com/HxD demo hack as described on github.

If you know the serial number of a volume, then it should be
possible to find the location of it on the exfat volume
and generate a new serial with the help of:

https://twlee.nz/changing-exfat-volume-serial-number/

NB I use linux and there are a couple of statically linked pythons
for that OS, I would have thought that similar would be
available for windows. A lot of system programming is done
in python which seems suited to a system task such as low
level disk file or volume operations.

Well, maybe I misunderstood the directions.
I have HxD (everyone does) so maybe I looked for the wrong VSN?

The instructions say to look in an HxD edit of Krylack for "1234ABCD".
https://gist.github.com/dreamer2908/59066658df2844746e5feadba7a589a2
"Use HxD to search for the string 1324ABCD and replace all instances with
the serial you want, i.e 12345678."

Unfortunately when I open KLVolSNEdit.exe in HxD64.exe, the resulting hex
dump of that Krylack executable doesn't have those 8 characters in sequence
when I run a search inside of HxD using
"Search > Find > Hex-values > 1234ABCD"

I can find 16 instances of hex "1234" but "ABCD" isn't associated with it.
And I can find 6 instances of hex "ABCD" but without a "1234" association.

If I search in HxD for "Text-string" instead of for "Hex-values" it finds 1
instance of hex "31 32 33 34" but without a text-string of "ABCD" (hex 61 62
63 64") being anywhere near in association.

Searching for "text-string" ABCD, there are 10 instances but none are
associated with "1234".

I made a copy of the KLVolSNEdit.exe executable from the Krylack site.
Name: KLVolSNEdit - Copy.exe
Size: 2253456 bytes (2200 KiB)
SHA256: 1D322FB2CDC76C8B16EAF0C123D0D29E4676E8058E7B908933D31D64B387D45B

And then using HxD I changed all instances of "1234" to "FFFF".
And I changed all instances of "ABCD" to "FFFF".
Name: KLVolSNEdit.exe_modified
Size: 2253456 bytes (2200 KiB)
SHA256: 40964790BD8208C4FAEF560C2C97BB873D146C8864CAD166B88EC2314EAFF1B4

When I ran the now modified file it came up and then said "corrupted".
What did I do wrong?

SpamBlk <Zap...@nospam.invalid> was right!

I had screwed up when I had previously followed the directions.
When SpamBlk mentioned that the steps work I took a closer look.

Here is a detailed set of steps which finally changed my sdcard VSN.
(Works on NTFS, FAT, FAT32 and exFAT file systems.)

(a) Read the instructions for modifying the Krylack CLI tool "volsn.exe"
https://gist.github.com/dreamer2908/59066658df2844746e5feadba7a589a2

(b) Go to the Krylack CLI tool home page
https://www.krylack.com/volume-serial-number-editor/

(c) Click the top left link to "Volume Serial Number Editor Command Line (volsn)"
http://dl.krylack.com/volsnsetup.exe

(d) That downloads an exe which is really just a winzip self extractor (apparently)
Name: volsnsetup.exe

SHA256: 89A1474383EA2BBC148D15085B1B6F16145488EE5B7C792849F759AE0A41E0A2

(e) "WinZip Self-Extractor - volsnsetup.exe" will ask for an "Unzip to folder"
c:\volsn (is the default but you can choose any folder to extract 7 files to)
Download GUI Version.url
KRyLack Software.url
LICENSE.TXT
Order.url
README.TXT
volsn.exe
volsn64.exe

(f) You can delete all extracted files but the "volsn64.exe" file
Name: volsn64.exe
Size: 2826384 bytes (2760 KiB)
SHA256: 0B60FE7F670585C0EC0F606FD2D49F22E7A82B170129DE1E3107CC87A8D7F190

Example:
volsn c c: 1234-ABCD Change volume serial number of C: drive to 1234-ABCD
Reboot is required to make the modification take effect.

(h) Place your exFAT formatted 64GB sdcard into your PC card reader

(i) Open a Windows administrator command window for all actions below

(j) As admin, run volsn64.exe in "list" mode to see your current VSNs

(k) Doublecheck the VSN using the Windows "vol" command
C:\> vol
Volume in drive C is disk 1
Volume Serial Number is AFC4-D0AA

C:\> vol E:
Volume in drive E is disk 2
Volume Serial Number is B9FC-EE8A

C: AFC4-D0AA -> 0000-0001
E: B9FC-EE8A -> 0000-0002
F: C64B-FE9D -> 0000-0000

(m) Obtain any hex editor such as the renown HxD64 hex editor
https://mh-nexus.de/en/hxd/

(n) Read the "volsn64.exe" file into that hex editor
HxD: File -> Open -> volsn64.exe

(o) Search and replace the one instance of "1324ABCD" with the desired value
HxD:Search -> Replace -> Search for: 1324ABCD -> Replace with: 00000001

(p) Save that newly modified executable to an unambiguous useful name
HxD: File -> Save as -> volsn64_00000000.exe

(q) Repeat the search & replace steps for the other desired VSNs you want
HxD:Search -> Replace -> Search for: 1324ABCD -> Replace with: 00000001
HxD: File -> Save as -> volsn64_00000000.exe

HxD:Search -> Replace -> Search for: 1324ABCD -> Replace with: 00000002
xD: File -> Save as -> volsn64_00000001.exe

HxD:Search -> Replace -> Search for: 1324ABCD -> Replace with: 00000003
HxD: File -> Save as -> volsn64_00000002.exe

/storage/sd1
Some Android file managers will uppercase the lowercase volume label
/storage/SD1
But other Android file managers will use the volume serial number
/storage/0000-0000

I tested the following file managers on Android 11
Files -> /storage/sd1 (com.marc.files)
Files -> /storage/sd1 (com.google.android.documentsui)
Explorer -> /storage/0000-0000 (com.speedsoftware.explorer)
X-plore -> /storage/0000-0000 (com.lonelycatgames.Xplore)
SolidExplorer -> /storage/sd1 (pl.solidexplorer2)
File Manager -> /SD Card (com.simplemobiletools.filemanager.pro)
Amaze -> /storage/0000-0000 (com.amaze.filemanager)

Note some tools which are not file managers require a hard coded path
when you wish to store their program data in a path of your choosing.

(w) Advantages of a simple Volume Label & Volume Serial Number
/storage/0000-0000 (in my case that's also /storage/sd1)
Plus if an Android app needs a hardcoded path - it's easy to remember now!
/storage/0000-0000 (often hardcoded paths won't use /storage/sd1)

(x) Notes:
Windows 10 format will only allow you to set the Volume Label
Windows 10 format will NOT allow you to set the Volume Serial Number

Linux "mkfs.exfat" format calls the VSN the UUID apparently
Linux "mkfs.exfat" format will allow you to set the VL & VSN
It's probably best to use capital letters as Android is kind of Linux
# mkfs.exfat -i DEADBEEF -n VOL_LABEL /dev/sde1

It is one thing to successfully applying a crack to a program in private.
Another to notify us, that you don't need suggestions, anymore. (Although
you did /not/ find a freeware solution for Windows.)

But posting a detailed cracking guide for a shareware program to acf, is a
complete and absolute *no-go*!! :-(

Acf did /not/ fork from acs, because the concept of Shareware was contested.
Sole reason was, to provide an easier access to free programs without any
shareware limitations. (Functionally limited, but altogether usable versions
of larger Pro tools are welcome, though.)

Group description of acf says "Free software that was intended to be free."
and not "Give me anything I want without paying."

Posting ways to make abandoned software workable could be considered a
gray area. But posting cracking guides to well-alive projects will do
nothing, but antagonize Shareware authors. They will be less inclined to
release programs with reduced functionality for free and offer their
full/pro versions for an acceptable price. They may even stop developing
tools, altogether.

So, even when putting the moral aspects aside, it is a "lose-lose"
situation. :-(

OK. Accepted.
I didn't know those rules.

Bear in mind it was already long ago published and found in searches.
However if you can tell me how to cancel the posts, I'll cancel them.

And I won't add any more to this thread from this moment forward.

Let's be clear that there are multiple methods that should work
(a) Linux "mkfs.exfat" (specify the VSN during exFAT format)
https://superuser.com/questions/1247972/how-to-change-vfat-partition-uuid
(b) Linux "exfatprogs"
https://github.com/exfatprogs/exfatprogs/issues/138
(c) Windows (calculate checksum using a checksum python script)
https://twlee.nz/changing-exfat-volume-serial-number/

This is something you rarely if ever need as the alternative is to write
down (or remember) the pseudorandom volume serial number when it's needed.

It has no value other than as being an interesting laboratory experiment.
But having said that - it was an interesting laboratory experiment indeed.

Xrn supports Cancel. (Supersede still is on ToDo.) Whether this Cancel
is accepted by the (first) server you post to, is not guaranteed. This
depends on quite a few prerequisites. And many Usenet News servers down
the line don't honor Cancel and Supersede, at all.

Instead of changing the number in the shareware, wouldn't it
have been easier to use it as freeware and then search for the string
"1234-ABCD" on the pendrive or whatever using HxD's Disk Utility, and
change that?
Don't forget to do a HEX search reversing the bytes.
"1234-ABCD" would be "CDAB3412". There are usually 2 values found so
"search all".
Maybe you have to change BOTH so as to not get corruption?

In FAT the first one is at 0x43
In NTFS it's at 0x48

I heard that the British Government makes sure all its

booze, but a deposit is made). Even the poor and unemployed get
something.. It might just be communist propaganda, of course.

Clearly, being blessed with being born British I feel under qualified to
pass judgment in this case. In times such as this may I suggest we call
upon the wisdom of Thomas Aquinas who argued long ago that it's morally
OK to steal if you and yours are starving but and it's a big BUT I
question if he was alive today whether he would extend the churches
forgiveness to cover nicking a bit of software because you can't be
arsed to memorise or write down 8 digits, and your pension is pants.

The British government does shite. The British pay for their benefits

profess their benevolence when they pay out minus costs for gold
wallpaper and other allowances.

Something and somethings. Maybe and maybe not. Yunno, freedoms from flim

getting nothing. Falling through the cracks they call it. I bet those

Actually, that is the same as us. They reduced it to thirty and then
upped it to thirty five. I have paid for about 45 years I believe. The
gravy train awaits. The meat and two veg though is anybodies guess.

There's no will in starvation: It's obligatory to moralism to eat
from the flesh of your nearest fellow human. In crusader bands
whipped by Christ's frenzy, such moral precepts became especially
fearsome foes of no small regard to those of the Muhammadan
persuasion, whose meat was tasty enough to the non-existent supply
train of alimentary ideology presented for empty stomachs at an empty
table. What moralism then is to forgive mortal transgressions is to
bountiful bouquet, conversely in turn, to feast of luxurious choices
largess is to bestow munificence the alms house and, of course, those
whom directly are to be seen benefactive administrators most of all to
be lauded the tract* so proclaimed.

It actually read for intemperateness of much less civility, cursorily

Just as Justinian coded the classical laws into abbreviated censorship
of volumes taught in Byzantium, Rome and Beirut;- just as lawyers
given five years' course study pretty much read [along with] anything
they goddamned well pleased. An eventuality, although well received,
his abridgements and subsequent revisions were later given to grow by
later redactions apropos to a diversity of cultures practising law.

A contemporary Russian from Moscow University wrote something similar
on the last page, comparatively a rather slim volume at that -- 'Feel
the worth of your corporal dualism, as in heaven, that you'll then
have relinquished to be freed from an imposition of earthly life.'

Probably a biblical hyponym.

-
“Teacher," said the lawyer, "what shall I do to inherit eternal life?”
“What is written in the Law? How do you read it?”

And he answered, “You shall love the Lord your God with all your
heart..."

“You have answered correctly; do this, and you will live.”

But he, desiring to justify himself, said to Jesus, “And who is my

The developer has changed his program. Now you don't find the string 1234ABCD anylonger with HxD. I tried changine all 12345678 to my vol id like AFAF-0909 to test. But the program now also checks it's own codebase. If you changed it detects the change and refuses to work. So you can't the hack to the codebase of the cli tool anymore. Just don't try you will fail.

What does work is to use DiskGenius (paid version) to HEX EDIT the boot sector with your new UUID (you can find the old one by reversing it) and then export sector 0-10 to a file. Use the python tool mentioned above and make it create a new file with the correct checksum. Check the contents of the created file, it should be a repeating sequence of 4 characters. Find the old checksum (also a block of repeating 4-chars) and replace the contents with the ones in the file.

And the last step is then to run chdksk <driveletter> /f, it will report errors and will fix it. This is because there's a backup boot sector after the first one (to recover from errors). As we have changed the first sector now the 2 sectors differs. If you've done everything correctly and the first boot sector has a correct checksum, the chkdsk /f command will replace the backup boot sector with the changed one and everything is good. If you've done sth wrong and there are errors in the 1st boot sector like incorrect checksum, chkdsk /f will copy back the backup boot sector and revert your changes so you have to start over again.

You might also want to change the VSN (not to be mixed with the UUID) to the same value. This is luckily a builtin function if DiskGenius and it's even available in the free version to make it look alike.

I tried this and it worked on exFAT microSD card and Android did not detect the change, it worked as if it was the same card as before.
