Someone told me that Windows XP will not work with 64GB flash
drives. Is that true? Thank you in advance for all replies.

Daniel,

The problem seems to lie in the fact that XP cannot *format* a drive larger
than 32 GB.

Funnily enough w98 had no problems with that, but that one FDISK could not
handle such a large storage ...

See what MS says about it here :
http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q314463&

If it is not pre-formatted, you can either paritition the
64GB drive or format it with something else, e.g. a Linux
life-CD. While XP cannot format larger than 32GB it has
no trouble using them when formatted.

Chances are that a new 65GB flash drive is formatted
with VFAT and works with XP.

Not true, it just cannot format (Without a third party app) using FAT32. I
have formatted a 64GB flash drive repeatedly on Windows XP Pro SP3 both with
NTFS or using a 3rd party app in FAT32 for use in an old media player.

GMAN,

My apologies, I should have been more clear in the specifics of it.

Luckily I provided a link to an MS webpage with all the details .... :-)

That's a limitation of formatting using FAT32 on the flash drive. The
format command in Windows XP won't *create* a FAT32 partition larger
than 32GB in size; however, that doesn't preclude you from using 3rd
party partition managers to enlarge that partition to encompass the rest
of the available free space on the device. Even if you create and then
enlarge a FAT32 partition, you will still have the limit of 4GB for the
maximum size of a file.

If you convert to NTFS then there is no such limit. If you format as an
NTFS partition on the flash drive, there isn't the 32GB limitation.
Under NTFS, you also won't incur the 4GB maximum size for a file.

It works after installing the Exfat IFS driver (KB955704) via Windows
Update.

Joseph,

From the MS webpage to that update:

"The exFAT file system is the *successor* to FAT32 in the FAT family of file
systems"

That could mean that exFAT is only usable on other machines having that
patch. It would be a good idea to check ....

Also read other posts here: Although XP cannot format drives larger than 32
GB with FAT32 there are other programs (including w98's FORMAT) which does
not have that limitation.

FORMAT does not *create* such a partition, FDISK(/the equivalent on XP)
does.

The other way around I'm afraid. Parititioning on an XP machine will
succeede, its the formatting that needs to be done either by a third-party
program or somewhere else.

"exFAT" is not a "successor to FAT32", no matter what MS tries to tell
you. It is just yet another file system, with marginal benefits over
FAT32 (such as being more efficient for larger partitions, and
supporting files greater than 4 GB), and huge disadvantages. It's main
reason for existing is that FAT32 is well-supported by non-Windows OS's
and embedded systems, without bringing in any income to MS. But since
details of exFAT are secret, patented, copyrighted, licensed, etc.,
there is little support outside Windows, and embedded systems that use
it have to pay royalties to MS.

It is difficult to imagine a worse choice of filesystem for any purpose.

Exactly, so basically if you are going to use that flash drive on any system
Xp or newer, you might as well format it NTFS

For specific flash media like SDXC you need that patch anyway.

Windows 98's FORMAT is actually a DOS program and it cannot format flash
drives, because Microsoft DOS doesn't support them.

So digging out tools from the stone age doesn't help. But of course there
are mkdosfs and others.

Simple solution: don't boot into DOS. :-)

I use Win98Se, and it FDISKs and FORMATs USB drives just fine. In fact
I set up a 320GB USB HDD using Win98SE. And, BTW, DOS drivers for USB
storage devices do exist. I use them. :-)

Yep, you're right. It's the FDISK command that creates partitions. It
is the FORMAT command (that you use to layout a particular file system
within a partition), as you noted via the MS KB article, that won't
structure a partition larger than 32GB.

http://en.wikipedia.org/wiki/Exfat#Disadvantages
http://en.wikipedia.org/wiki/Exfat#Support_on_other_platforms

The OP is asking about removable storage media. exFAT is usable only if
using the flash drive on other Windows or mobile hosts where exFAT is
supported or support has been added. Good luck with that.
