WD 2TB drive turns RAW, partition and RebuildBS failed,

#1 Post by xzhang22 » 08 Dec 2014, 17:46

Hi
My WD 2TB USB 3.0 drive recently somehow turns RAW. The drive is initially format as NTFS and usually mounted and used under Linux.

I firstly tried analyse of testdisk to detect lost partition table, but with no luck, the testdisk find FAT12 partition only. After reading a lot of threads on this forum, I decide go for advances and manually change format to NTFS, but list files still failed. With confirm on Boot, testdisk figures out that my boot sector and its backup are damaged, which lead me to Rebuild BS. After waiting for almost a day, nothing change, Rebuild BS give me another fail. After that I tried another analyse, but the result is even more strange. Any idea?

I attached log file as followings.

The correct partition table type is Intel, not none.
Please run TestDisk, Intel, Analyse, Quick Search, Deeper Search, Quit and post the new log

Hi Christophe
Thanks so much for reply.

Actually that's what I did in the first place. But anyway, I start over process as you instructed (Intel, Analyse, Quick Search, Deeper Search, Quit). I still get wrong partition FAT12, not sure why. I post the log in the following:

Any idea? should I change the type or geometry and run analyse or RebuildBS again?
