I recently bought a 64gb flash drive, which initially I thought was faulty. In order to make it readable to my PC (using XP) I had to download an add-on from Microsoft, after which the drive is recognised and can be used. Fine. It seems Windows won't recognise flash drives over 32gb in size, hence the need for a patch.
However, the flash drive is still not recognised by my HP laptop, which runs Ubuntu.
Does anyone know of a fix that makes this flash drive visible to linux systems as well as Windows?

I am using v 9:10
I get the impression from a similar query I posted on another forum that formatting to NTFS will allow both Windows and Linux t read the stick. Is this right?
If so that appears to answer my problem.

yes that would work just as long as you don't want to use it on a mac.

Thanks for confirming that. My only problem now appears to be the actual formatting. I use Paragon Partition Manager on my Windows PC, but that just shows the drive (formatted in exFAT) as unrecognised, and won't allow me to do anything with it. My Linux laptop doesn't even see the drive, so PartitionMagic can't do anything with it either.
Any suggestions on a freeware program that will actually allow me to make such a format?
Thanks again for your patience.

Sorry I forgot to mention I already tried GParted as well (in Linux) but with no joy. Still doesn't recognise the stick formatted in exFAT.

Try this: http://files.extremeoverclocking.com/file.php?f=197

Note: I've read that using this tool to format the drive in NTFS does not work. However, you may be able to format the drive to another file system after using this tool to format it to FAT32.

Might work. I have not tried it.

The 32 gb limit is a legacy of the fat32 file system as is the 4gb file size limit.

For Windows, maybe try the HP USB Disk Storage Format tool:

For Ubuntu, this topic may help:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/315710

Incidentally FAT32 doesn't have a 32GB limit, Windows Disk Management has an artificial limitation that removes the option to format to FAT32 if a drive is over 32GB. Windows by default will only offer NTFS as a format option for a 64GB drive.

32 gb limit has several origins and workarounds. XP has a soft limit that can be gotten around with software. Pre LBA bios's were limited by 63 sector hard limits. Award 4.5 bios bugs read disk translation above 32gb wrong until updated.
Most of those are moot in modern computers but can be invoked on purpose or by accident with bios settings.

I would have expected Gparted to be able to create any size ntfs partition as long as the original partition was removed, but I know there are some usb sticks that are unreadable under vista and ntfs so it is possible the kernel does not have an actual raw reader for some drives.

I don't have a 64g drive to experiment with.
