ShadowProtect 3.x desktop [licensed] is installed on 2 separate WinXP, SP2 systems (A and B for example). Background: "A" system is having erratic lock-up problems, usually within 30 seconds to 1 min. (or less) of booting. Lots of testing, remove unnecessary stuff, drive passed SeaTools, memtest is fine, no viruses, SAS and MBAM are fine, yadda yadda]. I would like to make one more full backup of the problem system before we send the system to the bench. If A's drive is moved to B, the partitions get assigned drive letters G & H, as expected. The question: While on B, can I use B's ShadowProtect to make a backup of A's drives (now G & H) which in future can be restored on A system using HIR? Or is there some reason that the drive being imaged has to be the booted drive?
