Well here's what happened.
I was doing some repartitioning of my internal hard drive using Partitionmagic 8.0.
While I was doing it, external hard drive was plugged in.
When I rebooted, my internal hard drive partitions were fine just as I wanted them to be but I got some error messages (can't remember exactly which) saying some data on external hard drive partitions was lost.
Now when I open 'My computer' I can't see any of the partitions of the external hard drive although I can see hard disk itself in Device manager under 'Disk drives'.
Also, if I open Partitionmagic while external disk is plugged in I got this message:
error 100 init failed
partition table is bad
and after that Partitionmagic crashes.
I also tried few data recovery applications like 'PC Inspector' or 'Data Doctor Recovery NTFS' but none of them wasn't able to do anything.
I might be wrong since I'm not expert for this kind of stuff but it seems data is still on disk but it's not accessible because of the table problem.
Anyway, do you have some advice or can suggest me what to?
I borrowed the external drive from my friend's father who has some really important stuff on it so I'm dead if it's lost.
Thank you in advance.
