I have an old Acer Aspire PC with Windows Vista, turned it on the other day to fine a blinking cursor. So I removed the hard drive and put it in a USB caddy and connected it to a Windows7 PC. In computer management I see 3 partitions:
1) 9.76 GB Health (Recovery Partition)
2) 69.77 GB RAW (Active, Primary Partition)
3) 69.52 GB NTFS (Primary Partition)
I can read the files on partition 3 but partition 2 which used to have the Vista OS now reads zero bytes and Windows7 says it needs formatting. I had a second hard drive connected that was a clone, and when I put that in the USB caddy it's the same result, which I thought was strange.
I ran a MiniTool Surface test which showed many blocks with read errors:

Also ran a MiniTool Partition recovery test which said it couldn't find the lost partition.

I also tested with GSmartControl and HDDScan.
Can I use TestDisk to rewrite the partition table, or is it beyond hope. Otherwise can I reformat partition 2 and use the recovery partition to re-install Vista on partition 2? Can any one advise please?
