Along with two older hard drives, I have been running two new Seagate Sata 3 hard drives for 2 months now. A few days ago I started the computer and one of the new drives appears now as a “unformatted drive.”
This is a 320 GB drive using the NTFS file system. As far as I know, there are no viruses or other programs that could have caused this. This drive is a single partition used for storage only. The other three hard drives run just fine.
I have used Partition Table Doctor software to try to recover/rebuild the partition. This program sees the file structure on the hard drive and says that it has rebuilt the partition table and the master boot record, but on re-boot the hard drive remains unformatted and unaccessible.
Partition Table Doctor offers the option to “fixboot” but clicking on that returns the message that it cannot fixboot.
I have two questions:
- Any ideas on how to recover the data on the disk?
- What caused this? It appears to be totally random, but there must be some cause?
