3 terabyte (3tb) filesystem RAW, boot sectors both "bad"

#1 Post by SkinsFan346 » 16 Mar 2013, 20:37

While attempting to format another drive, my 3 terabyte toshiba canvio external hard drive was "apparently" formatted (never got a format completion pop-up window), so it is possible a full format did not occur.

Either way, both boot sectors (original & backup) are corrupted from the looks of it.

The drive now lists the filesystem in windows (Win 7 pro, 64-bit) as "RAW".

I proceeded to run the testdisk software in hopes of correcting the problem.

I also ran a "Deeper Scan", and the following image is the end result of the search:

testdisk deepscan screen.png (42.84 KiB) Viewed 1455 times
My original log should be shown below (I am now currently trying to now "RebuildBS" via MFT search).

Admittedly, I am a bit ignorant on the inner-workings of hard disk recovery, so I appreciate any help that the community can possibly provide.

Thank you for your time, and have a great day.

Either your boot sector or your file system is damaged.
You can use tetsdisk and the menu "Advanced / Boot to diagnose it.
Please upload another screen shot or copy and paste the content of your testdisk.log.
At the menu List you can list and copy/backup your files first.
At the bottom of the screen shot, you'll find all the commands.
Checking that two dots and pressing enter, you'll come up on directory until you get to your disk selection.
You can select another intact disk as destiny/target where you can to copy your data to.
To navigate into a folder you can use your arrow key on your keyboard.
After backup (recommended) you can write/repair your boot sector using rebuild BS.
both boot sectors (original & backup) are corrupted from the looks of it.
Did Rebuild BS help?
If your file system is damaged, boot sector repair is not recommended.

Fiona,

Thank you for the reply.

The "Rebuild BS" via MFT search is still on-going (taken a couple of days...should be finished in the next 8 hours or so...numerous sectors).

When I click "Analyze" and hit "P" to view files on drive, positive results come up, which I believe my initial log shows:
dir_partition inode=5
* HPFS - NTFS 0 4 5 45600 36 4 732566016 [TOSHIBA EXT]

I am hopeful this indicates that if the boot sector can be "rebuilt", then the O/S might be able to recognize the drive once again?

If I am able to "view" files via the "P" keystroke, does that support the notion that the "filesystem" may be intact?

Looking at my log, how does it "read" to you? Are you able to gather anything of significance from it?

It is a new drive, recently purchased it (3/10/13) and just completed the process of transferring data from a 2 tb drive when the inadvertent format occurred.

Also, should I be concerned about the number of "heads" in the partition that testdisk is showing?
1 * HPFS - NTFS 0 1 1 45600 41 63 732566583
It is reporting 41, but should it not be 255?

I will upload results (screens) of the "RebuildBS" when it is finished. Hopefully, I am able to "list" files upon completion of this step.

Loading the information onto another disk might be tricky due to its size (3tb...do not have excess capacity on another drive). Obviously, I am shooting for a new boot sector, which might enable the O/S to recognize the HDD.

Thank you for your assistance Fiona, really appreciate it.

Brett
