Can I ask why you did that? Error messages are GOLD. What you add to it is "the story".
As it stands, I ask you to find a bla bla ... Oops couldn't resist... KNOPPIX CD, boot it up and see if it sees the data.
Try power off, open the case and reseat the cables and boards, then try again as well.
My 40GB Maxtor hard disk crashed. It cant be detected when booting up, giving a message saying that Primary.. bla.. bla failed. I even have tried setting it as Secondary using another hard drive as primary, the status still failed.
When I enter the BIOS, I can see that it recognises my 40GB hard disk. There's a lot of data in the crashed hard drive. How can I salvage the data in it. Is there any utility of software that I can try and use.
