From a prior related trhread 
(see :Re: "Grub loading ...Error 18" - HD's not accessible any more. (Kubuntu 
Karmic/ WinXP)  Date : Wednesday 21.51:33 and Thursday 16.20.10)

I infer the partition and possibly whole drive are severely corrupt. A Grub 
rescue CD cannot fix this,.
What may be worth trying is a good disk recovery tool.
Among others, from google I found <http://www.linuxdiskrecovery.com/>, that 
says:
"Linux Data Recovery Software by Recover Data Labs to salvage & recover linux 
files from damaged or corrupt partition having Ext2, Ext3 File system."
Or try another recovery tool.

Further consideration:
I have a vague feeling that what needs to be repaired first is at a very low 
level, not the files or file system, but the drive itself. I'd pay attention to 
this "bad superblock on /dev/sdb1" because (I believe) something at the 
beginning of a drive describes how the extended partition and the logical 
partitions within are organized, and it got corrupted.

I am really sorry not to be able to provide more help; I have no hard 
knowledge on the subject, only notions I've red here and there.
