NTFS readable with partition type 'none', windows wants to format the drive

#1 Post by axerqz »

I recently moved a 3 TB hard drive from a usb docking station into my desktop, which resulted in the drive becoming corrupt (in Windows, at least). Linux happily mounts my drive as a NTFS filystem (on /dev/sdX, not /dev/sdX1). Testdisk detects partition type none, and finds the NTFS filesystem along with all files. Selecting Intel/PC, however, shows the following output:

Code: Select all

Disk /dev/sdb - 3000 GB / 2794 GiB - CHS 364801 255 63
Current partition structure:
     Partition                  Start        End    Size in sectors

Invalid NTFS or EXFAT boot
 1 * HPFS - NTFS          120527  49 53 234813 237 34 1836016416
 1 * HPFS - NTFS          120527  49 53 234813 237 34 1836016416

Only one partition must be bootable

Is there any way to restore the partition table (I'm guessing this is the issue?) without having to copy all files to another drive (which I don't have, otherwise I would have done that)?

The safest solution may be to
- copy all the files
- create a partition
- reformat it as NTFS
- copy all the files back
