USB File Corruption

Hi,

Just recently, I've been having problems transferring data from my PC to my USB stick using Windows Explorer. Everything seems fine until you select a folder on the USB stick. The sub-folder names & filenames contain random letters/numbers/symbols. Strangly, some of the new created folders are fine.

I've re-formatted the USB many times (FAT32).
Still no joy. Seems to be OK when I transfer small files & folders.

I've used 2 USB sticks (8GB & 16GB)- same problem with each.

I've used different USB ports on my PC (front / back) - makes no difference.

I have Windows Vista (32 bit) and 2GB of RAM.

Any idea as to what the problem might be?
Transfer size problem?
Is there a file copy program that I can use instead of Windows Explorer?

Thanks,
Steve.

Hi rawprawn,

I tried the system file check.
No problems found.

Cheers,
Steve.

As a matter of interest, try copying to a cd.
Also look in Device manager at your USB Drivers.

You could try uninstalling the USB Drivers and then rebooting to let Vista reload them.

Hi,

I tried teracopy 3 times - all failed.

Small folders are OK.
Large amounts of data (GB) seem OK but are corrupt when trying to open. On the 3rd attempt, all files were corrupted (e.g. doc,xls,jpeg,mp3).
For info, the folders names were OK with teracopy.

How do you delete your USB drivers?
I went into Device Manager and USB Controllers. I'm not sure what (if anything) I should delete.

I am not sure of this but FAT32 only handles folders to a certain size. Could this be a line to follow? Do not know if memory sticts etc are suitable for NTFS - others may comment.

Probably worth changing - format to NTFS

john bunyan is right Fat32 will only take folders up to 4gb, I hadn't realised that yours were so big. This error usually occurs when people are trying to backup onto FAT32
