Craig:
Conceivably it could simply be a defective USB flash drive (it's not a
driver issue), however, we've run into at least three situations where a
flash drive was apparently mislabeled re capacity. (It's interesting to note
that in each case - as I recall - the actual capacity was always
significantly *less* than the advertised capacity - never more!). As I
recall the units were from different manufacturers.
Although you didn't say, I'm assuming that the flash drive is brand-new,
i.e., it's not a situation where the device was functioning properly and
this problem only recently arose. Assuming that's so, I would suggest
returning the drive to a vendor for replacement or refund.

USB 8GB drive, 2Gb limit
I have a USB 8Gb memory stick, formatted FAT32. When I go to copy
files onto each (each is only a few MB) the drive reports fill after
2Gb of content has copied. I am copying using XP SP 2 Pro
Is this possibly a driver issue and is there a fix for it, or does it
indicate a hardware fault on the USB drive?

Are you positive its Fat32 and not fat16?
Are you positive its Fat32 and not fat16? And are you making
subdirectories, not trying to dump everything in the root?

To further expand on what Bob I said, there are basically two types of formats
To further expand on what Bob I said, there are basically two types of
formats on a disk (other than NTFS), FAT32 and FAT16. In this case, the
bigger the better. FAT32 stores files more efficiently and allows the use of
disk drives over 2 GB. With a FAT16 system, you have a 2 GB limit on disk
size.
As for the "dump everything in the root," the FAT 16 system uses 32 sectors
of 512 bytes each to store the root directory. This limits the size of the
root directory on a hard disk to 512 entries. In other words, you can have
at most 512 files and folders in the root directory. Under the FAT 32
system, you can have as many files and folders in the root directory as you
want.
are you sure the stick is genuine?

perhaps a 2 gig stick made to look like 8 gig?

Re: USB 8GB drive, 2Gb limit
USB drive is new, was formatted to FAT32 and states 8Gb in windows
properties but wouldn't accept a 4Gb ISO file.
When I copied 400+ files of 4Mb each there was 1.98 Gb used in approx
100 directories and then the drive wouldn't accept any more.
I did manage to fill the drive completely after this using MS DOS
XCOPY but after checking the disk for errors there were errors in most
of the directories and it's now back to 1.98 Gb used.
FAT 32 has a file size limit near 4 GB and that could be your problem.
FAT 32 has a file size limit near 4 GB and that could be your problem. NTFS
is the only format that will accommodate more than 4 GB file sizes.
MS-DOS's XCOPY will fail (with or without errors) also if you try to copy
the 4 GB ISO file to the USB drive.
To put a file larger than 4 GB on a FAT32 formatted drive (and it doesn't
matter if it is a USB or internal drive) you need to split the file into
smaller sizes. I use a program from
http://www.filesplitter.org/ to split
the files and later recombine them.

What card reader are you using to put files on the card. I've heard of
problems where the reader was to blame, and a different reader fixed it.
(One chap had the issues with the built-in card reader on his Acer
laptop. Turned out to be an Acer hardware issue: their built-in SD card
slot wouldn't handle cards bigger than 1GB. Switching to an external
reader fixed his problems.)

Hello!
Hello!
BTW, exFAT supports files larger than 4 GB:

Re: USB 8GB drive, 2Gb limit
All well and good if you are using a Windows CE (embedded Windows) system.
While I browsed through the information I could not readily see where the
format could be applied to any flash device from Windows XP and I saw no
reference to XP being able to read a flash device formatted with the exFAT
format from a Windows CE device. I saw many references where an OEM can set
specific parameters for the device however, which would probably have
repercussions on a Win XP system.
