64GB Flash Drive

April 5, 2010 at 17:22:05
Specs: Ubuntu
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 think it may have been formatted in what is called exfat. Not sure there is a linux driver yet.

The problem could be fixed with partitions but MS will only see the first partition unless you reset the flip bit. Not all drives support it. It makes the flash look like an external hard drive so you can read more partitions.

You should be able to format it with ntfs and most newer linux systems with ntfs-3g will use it fine.

You are correct in that it has been formatted to exFAT. Are you saying that if I partition it (say in two) I could keep the exFAT partition, as this seems to work OK with any windows based pc, and set up another NTFS partition that would be recognisable to both Windows and Linux systems?

The first would have to be exfat as ms can't see more than one partition.

Linux can see nfts on the second partition.

Linux can make a fat32 all or ntfs all in either linux or ms.

Not sure what I'd do. Might try flip bit first to see how that works.

If money is no object see these people. They are supposed to have a linux driver. http://www.tuxera.com/

Aha! Thanks for that forum link. Now I see the problem more clearly, but not the answer. It looks like the last comment is the final nail in the coffin. What I'm trying to achieve is for the stick to be readable/writeable in both Windows and Linux, but the two seem to be mutually incompatible. Even if I format it in two partitions, the only one that will work in Windows is the exFAT one, and the only one in Linux is the NTFS, and it doesn't look like I can do much in the way of transferring data between the two partitions, which is what I wanted to do. Even using two 64gb sticks formatted differently wouldn't work...or would it?
Thinking more about it, if I formatted a stick to NTFS then Linux could read it, and so (apparently) should Windows, if it is all one partition. I'm not really worried about OS's older than XP, so do you reckon that will be my best bet? Just go to NTFS for the whole stick?
Getting ever more confused!!!

Format in NTFS

I wanted to say more but was afraid I'd make things worse. :)

Sorry to say that this doesn't appear to be an option for some reason. Windows sees the drive, but Paragon Partition Manager 8 (that I have used before) won't allow any changes and just refers to the drive as an "Unknown model" and suggests I repair it, but has no option for doing so.
PartitionMagic on my linux laptop doesn't even see the drive, so I don't appear to be able to use that either.
Any ideas on a freeware program that is likely to be able to see/repair/format this stick?
Appreciate your help.

"Seeing" the device is the most important first step.
You will have to use linux.
Try any live cd maybe to see if you can use gparted, fdisk or other partition editor/manager.

go to windows and then use the bulit-in partitioning tools to have 1 partition (they're in: Right-click (My) Computer and click manage)

OR

you can go to the disk and right-click and format and choose NTFS and click format.

And format the partition in NTFS.
