Windows XP formatted NTFS and Flash drive formatted FAT32
I recently got a OCZ 4GB Rally 02. I was replacing an old 1GB drive that was starting to corrupt a lot of files.
I loaded up the new 4GB drive and started using portable apps. However for no good reason files were becoming corrupted. I always do a proper unmount so this made no sense.
So today I reloaded the drive from scratch, formatted FAT32. Periodically throughout the day I would do a chkdsk on the drive. The drive had corrupted files even though I did not eject/unmount the drive. Even more bothering was that corrupted files were in apps that I had not even used today.
