It would on an Iyonix which has an improved DOS filing system.
You could format it under RISC OS, but it would then be invisible (in the
'unformatted' sense) to PCs, thus rendering it much less useful!
But, if you only want it readable by RISC OS, that would work.
You could put stuff in zip files instead - which should preserve the long
filenames for both systems, but it'd be a fag.
You can, if you wish to use it for transfer to and from a 'PC', add file
extensions in addition to your 8 characters. As it is, it's just like a
(big) DOS floppy.

I've just taken a file with a 34 character name out of a RO filer
directory and put it on my 1Gig Pendrive and all the characters display.
SARPC Select RO 6.06 and did work on previous versions.
A couple of things to consider.
1) I have Win95FS installed in my boot sequence.
2) Though I have the Filer Configuration "name truncation" set to 20
characters, I also have installed "!Fullnames" By Andrew Booker, which
reveals the full extent of a filer name when the mouse pointer is hovered
over a Directory/file.

I have a 1GB pen drive which I haven't reformatted, but files copied
to it on the RPC are only visible on the RPC, and files copied to it
on a Mac or XP PC are only visible on the Mac and XP PCs. It seems to
have two exclusive partitions. I also have a 128MB pen drive with is
fine.

"You can't have Windows without pains."
Its more likely to be down to the broken formatting used by XP. It
formats FAT16 with a FAT32 style variable size root directory, where
as other systems which handle FAT16 expect it to have a fixed size
root directory as the format specifies. This means there can be two
different root directories and files seen by one system aren't seen
by another.
The solution is not to trust Microsoft to conform to their own filing
system formats, and format the pen as FAT16 or FAT32 on a different
system.
Downloaded DOSFS 0.85 and this seems to have solved it !
Including being allowed to use lower case.
Where in my Boot sequence do I put the module ?

How does one do this? I would find it useful to have a RISC
OS-formatted pen drive but the Format option on the iconbar
menu of the device is greyed out.

The Iyonix is supplied with a SCSIForm application in Utilities.USB-Mass. I
assume a similar utility exists for the UniPod SCSI interface. Perhaps
someone could confirm for completeness.

You could just put it in directly in to PreDesk, but that may cause
problems in the future. A better solution is to create a sub directory
and constaining !Run obey file to RMEnsure the module. Then if you
ever have a newer module in ROM it wont be downgraded by something in
your boot sequence.

If you have access to Windows 98, this will also format the device so that it

MassFS 1 on the UniPod doesn't provide a FileCore filing system - it
emulates a single file which is presented as a PC card DOS partition, which
it then opens to implement the DOS formatting. So it's not possible to
format it for RISC OS. There is a program to format as DOS however:
http://www.riscos.info/index.php/Simtec_USB_technical
(did someone do a frontend to this?)
MassFS 1.99/2 on the A9 does provide a FileCore filing system and so there
should be a formatter supplied (is there?)

Yes. The UNIpod does not include a SCSI disc interface.
There are 2 Simtec /IDE/ ports for which a formatting utility,
IDEtool, is provided. This does provide partitioning facilities
for IDE discs but it is over 10 years old, updated in 2004.
There is no utility for formatting devices attached to the USB
port(s).
Theo has explained further, but to avoid potential confusion,
note that on the RiscPC MassFS is an application in
Boot.Resources entirely divorced from the USB interface to which
it attached and its firmware.

Indeed, and I tried that a day or two ago after you had
mentioned the USButil on another thread. On clicking to load to
the iconbar an immediate error "SWI not known in user code" but
it does load. then clicking on the icon "Unknown or missing
variable in user code", both are errors from WimpWorks.
It sounds as though it would be very useful for UNIpod users,
however.

It apparently runs on a SARPC, RO6.06 but, having scanned Unipod MassFS,
selecting a flash-drive and clicking 'Initialise' leads to
Error from MkDOSDisc
Unknown task
Couldn't change filetype in order to overwrite partiton
I don't know if that error results from some peculiarity of the flash-
drive, or if it is caused by that version of MkDOSDisc (22 Feb 2007).
(An earlier copy of MkDOSDisc runs, and formats, correctly).

How do you operate it? Set CSD to the drive and then save the

In what units is <size>?
Andrew

Copy MkDOSDisc to Library, and re-boot the machine (or, if present,
double-click ScanLibs, instead of re-booting).
The command needed is
*MkDOSDisc MassFS::<drive_name>.$ <size> -initdos
<drive_name> is the name of the flash-drive, ie the name under the USB
icon, on the iconbar.
<size> is the capacity of the drive in MB * 1.024 * 1.024
eg, for a 128MB flash-drive, named 'flash', the command is
*MkDOSDisc MassFS::flash.$ 134 -initdos

So do I, as noted in message
<57b7064f4f.old_coaster@old_coaster.yahoo.co.uk>. It seems that that
version of MkDOSDisc is not compatible with Unipod and/or RO6.06. An
earlier version does work, and I'll email a copy to you if you let me

The new version you sent me seems to have worked thanks. By this I
mean I just get a new command line prompt after issuing the above
(with 1GB/1076) set. The previous format seemed to be a DOS partition
however as deleting it required me to quit GuardDD (from the PC card
installation). How is this different?

My arithmetic makes that 1048. The specified size should not exceed the
capacity of the flash drive.

Different to what? Does the formatted drive behave correctly with both
RISC OS and Windows? ie can you read/write from both platforms, and can
you see the same file, from both platforms?

Several people have taken up my offer, but I'd like to put MkDOSDisc
(10 May 2006) where it is more easily accessible.
The history of the utility is as follows:
In 2006, Justin Fletcher announced that the copy of MkDOSDisc contained
in the, then open-source, PCPro 3.06 could be used to format a DOS disc
under MassFS.
In fact, it didn't work properly but, after taking up the matter with
Justin, he fixed it, and told me that he would upload it to his website.
Notwithstanding a reminder, the utility has not appeared there.
I have an email from Justin in which he says that MkDOSDisc is freeware,
and that I may do as I please with it. Since I don't have any webspace,
would anyone care to suggest an appropriate home for MkDOSDisc?

GuardDD just protects against DOS partitions being deleted as PCPro
requires a partition for Windows98.

Well I thought the point was to format the drive in a way different to
its factory setting - which didn't allow the files to show on both
platforms but could be recorded upon by both.

For me, after using MkDOSDisc to format a flash-drive, I can read/write
files to it using RISC OS, I can read/write files to it using WindowsXP,
and files written by RISC OS can be read by WindowsXP, and vice versa.
If yours doesn't do that, try formatting it to FAT 16 (not 32) on your
Windows machine then re-format it on the RPC using MkDOSDisc.

Excellent stuff, good man.
A question if I may.
In the ReadMe an example is...
eg, for a 128MB flash-drive, named 'flash', the command is
*MkDOSDisc MassFS::flash.$ 134 -initdos
Where does the 134 in the command come from if it's a 128MB flash drive?
1024 * 128 = 131072

It's the [nominal capacity of the drive] * 1.024 * 1.024
so in the example: 128 * 1.024 * 1.024 = 134

That's good. Incidentally, using it with USB-util, as explained in the

DOSFS on all version of RISC OS except RISC OS 5 only handles
FAT12/16. For FAT32 you need either RISC OS 5, or Win95FS on
anything else.

I doubt if XP deleted any files but what, exactly, happened? You saved
files to the flash drive, on the RISC OS machine, and now they cannot be
seen on the XP machine? Or you saved files to the flash drive, on the XP
machine, which now cannot be seen on the XP machine? Or ... ?
Anyway, I would suggest copying the files from the flash drive, wherever
they are accessible, and then re-formatting the flash drive.

Because Microsoft knows best?
More seriously, did you go through the "Safely remove hardware"
bit on Windows after altering the drive's contents?
Dave
Whats more likely is the drive is formatted to XP's bastardised
version of FAT16 which doesn't follow the published standard. This
results in Windows and RISC OS using different root directories,
so you can see the files written by one machine on that machine,
but the other machine either shows it empty, or containing a
completely different set of files.
The solution is to either use Win95FS which can work with XPs
FAT16 (or better still FAT32), or reformat the card either on
Win98 or using a RISC OS utility (mkdosdisc, mkdosfs, etc).

I was referring generally to the thread: I have a memory stick which
I'd formatted with MKDOSdisc to be read/write compatible on ROS and
WXP. On inserting it into a WXP machine today, it suddenly blanked
(and verifiably - I'd just seen the origianl files on another WXP
machine) and presented an empty disk. The new files I saved but
nothing else are visible on ROS.

Heh. We can run down the relative merits of RISC OS hardware but I've
not see it do something as stupid as this.

I didn't alter them, WXP did apparently.

It was formatted using mkdosdisc but for whatever reason, XP seems to
have formatted it again. I just inserted the stick and clicked on the
"open folder" (from memory) option in the window it shows.

XP won't have formatted the drive, unless you issued a specific
instruction to do so (My Computer > right click the drive > format).

If the files were saved, via Unipod on the RISC OS machine, did you
dismount the drive before removing it?

Funnily enough on saving a textfile to the disc via the RiscPC and
then dismounting and putting it in the Iyonix almost all the files
were deleted and the textfile corrupt.
Andrew

What does that have to do with XP?
Connect the flash drive to the RPC, format it using MkDOSDisc, and save
some files. If the files are unreadable, or absent, when the flash drive
is read by the Iyonix, and/or XP, the flash drive is probably faulty.
Tony
It doesn't apparently have anything to do with XP but I'm just
reporting what seems to be a bug whereby the contents of a (AIUI)
drive that is recognised by both RISC OS and WXP seem to be erased for
no apparent reason.
Andrew

Does 'erased' mean that the files have really been deleted, or just that
you cannot see them in the filer window?
If, by mistake, you have formatted the flash drive using XP FAT32, you
will find that files saved on the XP machine cannot be seen, when viewed
on the RISC OS machine. Similarly, files saved via the RISC OS machine
cannot be seen, when viewed on the XP machine. However, in neither case
have the files been deleted, as you will see if you re-connect the flash
drive to the machine on which the files were saved.
To fix this, re-format the flash drive using MkDOSDisc, as I said above.
Tony
> To fix this, re-format the flash drive using MkDOSDisc, as I said above.
Almost, but not quite. FAT32 works ok, but you'll either need an
Iyonix or Win95FS on the Risc PC to read it. The problem you describe
above with files only seen by the system theat writes them is due to
XP's bastardised version of FAT16, which illegally uses the root
directory from FAT32 and therefor can't be seen by DOSFS.

I cannot see them in RISC OS or WXP.

Not as far as I know. All I know is when I put the drive back in the
Iyonix the files had gone.

Thanks for the clarification. I use an RPC without Win95FS so, as you
say, FAT32 doesn't work for me. However, I have found that FAT (not 32),
via Win2k, does work.

If the problem persists, after correctly re-formatting the flash drive,
the flash drive itself may be faulty.

Do you have a "recipe" by which I can format a flash drive of an
appropriate size, to this problematic version of FAT16?
Do you have any Internet references on its structure?
Dave

Pop the relevant terms in to google groups, its come up several times
before.

That, of course, is not a helpful response.
To clarify what sort of information I'm looking for, and why I'm
looking for it: I want to examine a device with this format so I
can see about modifying !ROFS so it can cope with it. So I need
a reliable recipe to reformat a device that I already have to the
problem format, or to be able to buy such a device. Also, if you
know so much about it, you've probably found a specific reference
to the detail of the format. I've just found around a third of a
million hits in Google, and it may be some time before I reach a
hit with any hard information. If you possess this hard info,
you might save me a lot of time. In turn, I might help a few RISC
OS users by providing them with some useful software for free.

As I said use google groups, there are far less than a million hits
for csa.*

Perhaps someone else can help me. I want to get my hands on a
device that has the problem FAT16 format, so that I can make
!ROFS read it. I had hoped that I could "just" reformat a
128 GB USB pen that I have, using XP, so I did that a few
minutes ago, then transferred a number of small files onto it.
I can see all the files, using RO5's built in filer (which
sees it as SCSI::0) or using !ROFS. So simply using Windows
XP to FAT-format a small drive isn't enough to guarantee that
it will get the problem format. (!ROFS's "Stats" shows it as
512 bytes per sector, 4 sectors i.e. 2048 bytes per cluster,
1 reserved sector, 2 FATs, 245 sectors per FAT, 32 sectors in
the root dir, base of root dir = 523, FAT type FAT16.)
Can anyone give me a can't-fail recipe for producing a drive
with the problem FAT format, please? I'm prepared to buy a
drive if I have to (and if it's not expensive).

I have just tried to do this, using an old 128MB drive, but failed!
Having formatted to XP FAT32, I found that files saved on the XP machine
_could_ be seen on the RO machine, and vice versa. I also obtained the
same result, when the drive was formatted to XP FAT.
Since I first noticed the problem, maybe a year ago, there have been
some changes to my systems: the XP machine has been upgraded to SP2, the
RISC OS machine has been upgraded to RO6.06 (from 4.39) and I'm using
ROOL's DOSFS 0.85 (instead of whatever RO4.39 or RO6.06 provide). Maybe
these changes fix the problem?

I've only had the problem with a 1GB pen drive. My 128kB one is OK,
but almost certainly it's FAT16.

Do you still have the drive, and is it still causing the problem?
Dave
I still have the drive. I haven't used it for a while, but I don't
think anything's changed. It was only exposed to XP once, but afair
the Mac reads and writes to the PC side, not the RO side.
Right. Is there any chance that I can either borrow ir from you,
or buy it from you? This is only a useful thing to do if it really
is still in the state that causes the problem.
