I only see 3 of my 4 Hard Disks in the Acronis True Image 11 list when attempting to backup. I thought it was due to the SATA and IDE both being Primary-Master hiding the IDE drive, so I moved the IDE to Slave and stil cannot see it. Current config is IDE- 200GB Primary-"Master" V: IDE- 200GB Primary-"Slave" R: not visible (tried on both slave and master) SATA- 500GB channel 1 "Master" C:, D:, P: (OS drive XP and Vista dual boot) SATA- DVD-RW shannel 2 "Slave" Z: eSATA- 750GB channel 6 "Slave" ASZ I only have 1 IDE channel that I can use and obviously that is used by my to older drives. That SATA designations are what windows is listing them as and trying other channels for the SATA drives results in the same designations 1, 3, 5 - Master 2, 4, 6 Slave all are called Primary ATA. If someone can give me any suggestions I would greatly appretiate it as the 750GB is for my ASZ and I need to be able to backup the other drives to it. Thanks in advance for any help you may be able to provide.
