I have a fairly unique issue. I have a corrupt hard drive that will boot and go into windows but will experience bsod after about 3 hours of use. I have ran check disk from the repair console twice (both times finding and repairing errors). I ran check disk and then cloned the corrupt drive to a new (raw) WD hard drive using HDClone. The cloned drive booted to windows on the initial try with no problems. Every subsequent attempt to boot the new drive would cause the computer to hang in post for several minutes and then try to boot from cd. I believed the new hard drive to be faulty or that I had brought the issue from the original drive to the new drive by cloning. So onto my second new hard drive. I once again used HDClone to copy old to new. This time I experienced the problem right away. The computer would hang in post and then enter windows. So at this point I have concluded that cloning was not going to be an option. So I format the 2nd new drive and do a fresh install. After the install, low and behold I get the same issue, hanging at post and unable to enter windows. Now I am really puzzled. Worked on this for a couple of days with no solution. So at this point I take another new hard drive and install windows and everything is fine. I load all the drivers and set up the system for use. The last thing I do is slave the old drive to the working drive so I can copy critical data to the new drive. BAD IDEA! I return the computer to the workstation turn it on and it hangs in the post and refuses to enter windows. Totally at a loss now, I take the latest new drive and perform a low level format and then re-install windows. Once again, same issue, computer hangs at post and no windows. Not a clue what would destroy a new drive by simply slaving in to a corrupt drive. Any suggestions would be greatly appreciated.
