What is the deal with Windows and SanDisk?I have one PC and one laptop running Win Vista - and another PC with Win 7. I've used a SanDisk flash drive on all three for years without a problem.
Have you tried reformatting the flash drive after after using it in a Linux environment?
BTW, a better solution for moving files rather than a flash drive is
FileZilla.
I didn't suggest it because it requires some technical knowledge/capability and probably couldn't be labeled the "easiest."
I’ve tried formatting the USB drive, no change in behavior. From a Google search, it appears to be a Win 7 issue. Works sometimes. A hobby OS like Linux, no issues.
