|1) Thanks to Wanderer: Partition, Find and Mount failed. Will try others.|
2) Thanks to John:
Are they IDE or Sata? Yes IDE
The two drives were working perfectly with data on them in the old comp.
"The problem was shown after moving these two drives to a new PC"
Did you install a new copy of XP? - Yes a new copy of XP was installed on the first primary Drive. The 2nd drive was not added after.
"I do not want to create a new partition in fear of losing data on the 2nd"
Back it up.
Does it also have an operating system on it? - I tried to use the 2nd Drive alone as Master, but could not start the PC. So no operating system installed on the drive.
