WD 1 TB harddisk not accessible

#1 Post by hteeniv » 05 Dec 2018, 15:01

I have posted a similar query a year ago and got a very helpful solution to recover my data. Now an year after my new harddisk just 1 year old has got a similar issue. The harddisk is not accessible any more. Not detected in the windows file explorer. Only thing is the USB device connected logo.

Please find the below logs.Also just FYI, last year my old WD was detected as Intel but this one is detected as EFI.

The type of the file system is RAW.

The situation I faced last time was a different set of errors and I was advised to clone using DDRescue and try to recover. This time too do I have to follow the same steps?

Run TestDisk. In Advanced, select the partition, Boot, BackupBS, confirm, Quit
If Boot and BackupBS are missing, do you know if you had an exFAT or NTFS partition ?

I tried the Advanced mode but yes as you mentioned there was no Boot and BackupBS option.
Referred to my logs on this forum dated 14Oct2017, this hdd is NTFS format.
