[Ham-Computers] error performing inpage operation on hard drive

[Jonathan Thawley]

I have an external USB 320GB SATA hard drive split into two
partitions... the first one is where all my programs are installed and
the 2nd one is where all my data is stored (this was my main drive
until my motherboard and power supply went in my other computer hence
why it's in a usb enclosure)... wellll i just my computer off last
night before i went to work and when i came in this morning about 7AM
and turned everything on I can see the first partition fine and when i
try to open the first partition I get the following error: Error
Performing Inpage Operation. another thing i notice is that the drive
label is now changed to Local Disk.  Any ideas how i can get my data
back before I have reformat the drive and loose it all?  I tried
reading some info on google but it made me more confused... i read
something to the effect that I need to hook it up to a linux machine
and extract the data that way.

Anyone have any ideas on how to solve this problem?

Thanks,

Jonathan
