HDD is not accessible. Possible MFT corruption. How do i proceed?

Solution 1:

No guarantees, but try Testdisk.

TestDisk can:

Fix partition table, recover deleted partition
Recover FAT32 boot sector from its backup
Rebuild FAT12/FAT16/FAT32 boot sector
Fix FAT tables
Rebuild NTFS boot sector
Recover NTFS boot sector from its backup
Fix MFT using MFT mirror
Locate ext2/ext3/ext4 Backup SuperBlock
Undelete files from FAT, exFAT, NTFS and ext2 filesystem
Copy files from deleted FAT, exFAT, NTFS and ext2/ext3/ext4 partitions.

Solution 2:

Try launching a DVD version of Ubuntu. I've had some success in the past accessing a drive.

Solution 3:

I've recovered seemingly trashed / inaccessible drives before using a combintaion of cloneZilla or sometimes, if it's really bad, dd.

You can make a bootable clonezilla CD and use it to copy the drive contents to another drive if the broken disk has physical damage; if it's more the corrupt data that's the problem then dd may help.

Using dd does require a fair amount of *nix hackery experience, bewarned.

I'm not sure how much this will help but I've had alot of success in the past with these tools, hopefully your problem can be fixed. Good luck :)
