Hi there,
Apologies in advance if my post seems kind of repeated, but I tried several other things I saw in other threads.
My experience with Linux is not that good.

I have an external HD, WD800 with 80 GB of capacity. Everytime I connect it to Windows it asks me to format it. I tried to run CHKDSK and it said the file system is RAW.
When I tried to mount it on Linux, it said "I could not mount the drive.....the file system is not specified"

Any suggestions on how to work on that problem??
I would really appreciate your help.
Thank you.
