i dont know what that error is BUT if you cant get into windows and u wanna back up some info then :
Take the corrupt hdd out and install it into a working computer.....
On the computer you know that works ( the one u just installed the corrupt hdd into )
1) download a prog called BART PE
2) Boot it from cd rom
3) Once it loads up go to start, programs, total commander
4) Now select the hdd either c: or d: and on the screen next to it select another hdd either c: or d: and then copy the files you wish you backup to the working hdd....
Works for me
Good luck....
If you dont want to do this then google the error message....
