I recently purchased an HP 16gig USB Flash drive for a customer of mine and configured backup software to copy files to the drive every couple of hours. While it appears to work most of the time, we continue to run into issues where the drive becomes inaccessible. The backup software asks for a disk to be inserted into "F:". Removing and reinserting the USB drive makes it work again for a while, but the problem eventually resurfaces.
I do not want the customer to have to worry about removing/reinserting the drive at any time.
We have checked the power saving settings to make sure that nothing is being turned off during idle time. We also looked for potentially conflicting software that might be run on a schedule. But there does not appear to be any obvious culprit.
