Not sure which drive to select

#1 Post by nkoscik » 10 Sep 2013, 00:26

I've been working at my external HDD for the past few days and I'm at a loss. I would really appreciate someone's help walking me through repairing my hard drive.

This where i'm stuck. I'm trying analyse my 1TB drive but i'm not sure whether to select "PhysicalDrive1" or "Drive I:".

Anybody got any ideas?

Did you use the 64bit version of testdisk?
The 32bit-version is recommended.
The 32bit-version of testdisk provied better informartion.
So it's going to ease the use of testdisk and you should prefer to select your disk!
You can repeat your diagnose using the menu Analyse, Quick and if no partition is found, Deeper Search also.
After your diagnose, you'll find a file called testdisk.log in your testdisk folder.
Can you open it and copy and pase the content into your next post?

Thanks so much for your quick response! Using the 32 bit version of Test Disk worked. I only saw one option for my HDD. I analysed it and wound up here:

I have no idea where to go next!

Also, here's the log:

The partition table and the NTFS boot sector are ok.
Can you list your files using TestDisk, Advanced, List ?
If it's the case, run "cmd" (right click "Run as administrator") and "chkdsk /f I:".

To answer your original question, it's usually better to select the physicaldrive (whole disk access) than using a drive letter (single partition access)

Thanks for responding! As of right now, I've figured out most of the issue and it doesn't look very good.

After I switched to the 32 bit version of TestDisk, things seemed to run smoother. I analysed the drive and concluded that I was going to have to go into the advanced sub menu. I rebuilt the boot sector (which took forever!) and then I found a problem. The backup BS was not the same as the primary BS. All I did was select the Back up option and then both boot sectors matched up. When I selected Repair MFT, I got this error:

MFT and MFT Mirror are bad. Failed to repair them.

TL;DR: My MFT is irreparable. Is there anything else I can do to regain access to my drive? And if not, does anybody know of any data retrieval software that doesn't jumble all of my files? i.e.) FILE001, FILE002, FILE003, etc.

Ran into same problem you did with boot and mft being corrupt. Know there are lots of options avail but I chose to use GetDataBack for NTFS V.4.32 byhttp://www.runtime.org/data-recovery-products.htm. Since my computer was not running at all and could not install anything, I needed a recovery software that could run from CD so I downloaded the Runtime LiveCD, which is near the bottom of the link I just gave you above. It worked like a charm and I didn't pay for it until I knew it would work. I actually purchased a few of their programs and they offer discounts if you purchase one of their bundles.http://www.runtime.org/prices.htm To me, it was a small price to pay for guaranteed recovery and my files are still transferring to my new external drive so I am very happy! One thing about using the LiveCD is that my external drive wasn't listed as like Drive D: so at first I thought it wasn't recognized but it was listed in like UNIX dev/sdc1... etc. Again, free is good but little price for something that works is great too. Good Luck! ps. I posted my problem a few days ago on this forum but had no one help me and that is why I had to look for other resources when I found GetDataBack. Hope this info helps!
