I bought a 512GB USB flash drive, formatted it to NTFS. It has less than 500GB. wbadmin reports that it can't find the drive. Do I have to buy a 1TB flash drive? Any suggestions would be appreciated.
Hello Gary,
Yeah, seen that before. It seems that wbadmin does not see a USB Flash drive as a valid target for your backup. It is better to use an ordinary USB drive. No need to buy a bigger flash drive if you have a spare USB drive.
Used a WD USB 3.0 drive. Get an I/O device error. Installed a new USB 3.0 card. Get the same error.
The backup command returns the following:

The operation ended before completion. The request could not be performed because of an I/O device error.
You need to have a look at your Event Log and find out which device is causing the I/O error. It could well be that your drives or arrays in the server are malfunctioning.
There was a disk error in the event viewer. Device manager showed that a SES driver wasn't loaded.
Easy way out was to use a different drive, an IOMega USB disk drive. Backup completed sucsuccessfully.
Thank you for your assistance; should have been able to solve this problem myself.
