Old IDE hard drive data not detected after a new drive installed.
Posted on 2007-10-21
Okay, something weird has happened. I have installed a new hard drive and now the original drive will not boot!
First - I booted up my clients system with some new RAM, just to check the speed. Worked great. I then installed a new hard drive making the old drive the 2nd IDE drive on the Primary channel.
I ran the Windows XP installation and when it came to the point of which drive to format, I stopped and exited and removed the 2nd IDE drive (the original with the OS still on it...didn't want to format it by mistake!)
I rebooted and ran through the Windows XP install. New drive working great with all patches etc.
I then decided to add the original drive back as a slave to transfer over any data. I set both drives up on the Primary IDE channel and used Cable Select.
Booted up...CMOS sees both drives correctly...go into Windows XP and look at My Computer and the 2nd drive is not there?????? I check Disk Management....it sees the 2nd drive but as 'unallocated'
What did I do wrong? Is the data lost? I tried booting up again with the original drive back in and the new drive removed. Same result...will not boot.
I will be trying the drive in another machine. Any suggestions?
