Re: HD acting strange
Welcome to TSF.
Have you tried the drive with another operating system and/or machine? What format(s) did you use on the drive?
Bad superblocks and bad magic numbers are a bad sign. Your drive may need reformatting or even replacing.
If you have the space and feel comfortable with the command line (I'd guess yes since you use fdisk) you could use dd to try and make an image of the hard drive. Let us know if you want to try that and need help with the command (it's been a while since I've used it, so I can't think of it immediately).
Has it been a few days since I replied to your thread? Don't panic! I'm usually very busy and may forget a post if I'm extra busy (or it might just take me a while to be able to do a decent reply). If you still need help and are awaiting my reply after a few days, PM me about it.
When posting what errors you get, please give the full message. It makes helping you much easier.
