Hi, I upgraded a laptop (IDE) hard drive & decided to use the 40Gb drive in an external USB caddy as extra storage for my desktop PC. Everything worked & PC recognised the plug & play drive in the normal way, so I decided to format the drive & started a check disk/repair bad sectors if any etc... 5 minutes into the task I had a power cut, started up the whole job again but now the USB drive is unregognised & does make a very strange screeching sound for a few minutes. I have tried a partition manager program & this also fails to recognise the drive exists. Can I rescue this USB drive? Thanks in advance.
