Invalid FAT Boot Sector

#1 Post by Jade »

Hi there,

I have a bunch of old hard drives I am trying to access, this first one I am connecting to my PC with USD. It is IDE. MY goal is to just get the data off it onto my PC.

It hangs for a few minutes when trying to access then comes up "Parameter Incorrect" when trying to view files.

The below is the Analysis on TestDisk.

I did QuickSearch which found nothing so did a Rebuild BS...which ran for a few hours then got stuck at 24%.

I am now doing a DeeperSearch (which I should have done before the Rebuild BS I guess), but I feel as if this may get stuck aswell as I am thinking it may be a hardware problem.

I will post results (should be around 7 hours the speed it's going) but am thinking I might need to do a DDRescure to PC HD and then rerun?

Thanks - should be a Analyse pic below and the log.
