My uncle's friend has Sony Vaio MCE PC. It won't boot up or POST or anything. I narrowed the problem down to 1 of 2 identical hard drives. When I unplug both drives, it starts, when I plug 1 drive, it starts. But when I plug in the suspect hard drive, in any way, the computer turns off or it won't turn on at all.
So, being identical drives, I swapped the PCB's on the drives and the computer will start (at least) with either drive plugged in as long as it has the "good" PCB attached.
Now, upon getting either drive to spin up and not being able to boot into an OS, I realized that the drives were in a RAID 0 from Sony.
So my questions are:
1. is it likely that a bad PCB on a HD could prevent the whole machine from powering up?
2. Is there a way to recover a RAID 0 using only 1 disk at a time (the reason being that I can only get 1 drive w/ the "good" PCB to work at a time).
3. Am I better off trying to get a replacement PCB from ebay. I only flinch at this because of the time and money vs. uncertainty of success. Are my chances good?
4. Does the RAID configuration explain why I cannot get either drive to be recognized on another PC when I connect with a SATA/USB adapter.
I thought about trying to do an image of each drive and rebuilding to new drives, but I don't think the drives or data would be recognized by Acronis, Paragon, or Drivesnapshot, or even Linux or whatever.
Any useful ideas for this science project would be appreciated.
