fedora

I bumped to a huge (for me) problem. I was running dual boot system (win 7 / linux) and at some point I decided to test fedora ( I am new in Linux ).

My hard disk conf: 3 hard disks each 1 TB, 2 set to raid 0 with windows running on it and 1 for linux. After installing it from live usb I found out that windows 7 is not in grub anymore and while booting shows raid error. I installed back Ubuntu and ran Disk Utility and checked now I have one disks (raid 0) failed (READ) error. First has 5 bad sectors and second has 1 bad sector. And now I dont know what to do and how to repair. further I dont know which data i could provide to get help.

I tried ntfsfix and got this output:

Mounting volume... NTFS signature is missing.
FAILED
Attempting to correct errors... NTFS signature is missing.
FAILED
Failed to startup volume: Invalid argument
NTFS signature is missing.
Trying the alternate boot sector
Unrecoverable error
Volume is corrupt. You should run chkdsk.


#sudo ntfs-3g -o force,rw /dev/sdb /media/windows
NTFS signature is missing.
Failed to mount '/dev/sdb': Invalid argument
The device '/dev/sdb' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
