I store my backups on an external enclosure connected to an add-on card. Backupper does not see the disk when I boot from the WinPE USB Flash that I created.
I tried adding the drivers although I do know for sure that they are not needed. The enclosure takes 4 drives (using port replication) but the one in slot #1 is visible by the PC without drivers. I can actually see my drive in the BIOS. I tried connecting the drive to sata port on the MB and then it worked, Backupper saw it so I know it's not an issue with the drive.
So the question is. If my BIOS sees the disk although it's connected to a RAID Card, shouldn't Backupper also see it when I boot from the WinPE USB flash drive ?
