4TB disk, boot & backup boot sector bad, disksize wrong
Posted: 30 Jun 2014, 17:31
Hi all
my 4TB Western Digital Mybook suddenly failed, could be a powersurge or whatever, but it just quit, all files gone, dick not reconizable in windows. The LED that usually blinks intermidiate during I/O stayed on permanently and the disk kept spinning rather than power don as it should after a short period of non-activity.
The harddisk is a TGB HGST, label says LBA 7.814.037.1568 Sectors CHS: 16383/16/63
Both bootsectors are reported as bad by TestDisk, and the disksize is reported as 1801 GB.
I did a scan and one attempt to rebuild the boot sector from the MFT, to no avail.
Can anyone advise me on how to proceed to save the files on the disk?
Thanks in advance for any comments on this issue.
