Help Support needed! CWM unable to find E:/data

[sally5]

Hello!

I have a i9000 which I recently rooted. I did a nandroid backup after installing CWM. I then proceeded to install the ICSSGS RC4.2 .

And that was successful. It worked fine for over a week. I then wanted to restore it back to default TouchWiz, so I booted into recovery and initiated a recovery from earlier backup.

Then when I rebooted, it did not go past the i9000 Galaxy S Splash screen. Its stuck there. When I try to restore again or install from ZIP, it does not work. It says

E:unknown volume for path [/data]

I guess I can get help for this. I just want to get the phone working again. Either TouchWiz or ICSSGS RC4.2

Thanks for your help. In advance
