Partition issues with 3TB drive - newbe

#1 Post by gdoran » 03 Oct 2012, 16:06

I have a 3TB external drive(actually two is a Buffalo Drive system enclosure) that apparently got messed up due to improper shutdown. Windows 7-64bit is showing it in Disk Management having two partitions, one 2048.00 gb unallocated and a 746.21 GB unallocated but there is just one partition on the disk. The second hard drive is showing up perfectly fine as a Basic 2794.08 GB NTFS healthy primary partition. Analyse is still running, I am posting what has come up as of 89% complete, hoping that this might be enough to give me some direction. I will post the rest when it is done

Thanking you in advance for your help!

Re: Partition issues with 3TB drive - newbe

#2 Post by gdoran » 04 Oct 2012, 18:27

After three days on analysing, here is what we came up with. It said there were two partitions that could not be recovered and I selected ok, then it said hard disk (3000gb/2794 gib) seems to small << 600gb/5588 gib, check hd humpers and bios detecttion (see attachment for actual print screens). Then it showed me a partition, ntfs, blocksize=4096, 2199gb/2047. This eems very strange to me because I originaly could read files and copy, even through around 480gb it did seem to start at square one with the copy. It is a two drive Buffalo Drive station that has the ability to do two forms of raid, one a mirror and one combining the two drives into a 6 gb partion. Not sure if that is causing problems? I would really appreciate some insight on how to proceed since I have over a 1TB of data on the drive.
Thank you in advance.

I've no experience of that fault but out of curiosity I googled the key word

"$MFT has invalid magic"

and found these hits which might give some clues ..

Thanks for your input. It seems pretty odd, TestDisk seems to know all about the filesystem, it pulls up directories and files that appears to be valid, I would just copy everything off but there seems to be a problem when the copy hits around 480GB for the single file.

I've suggested to users in other posts to try a free trial of RecoverMyFiles (i.e. just use in evaluation mode)

http://www.recovermyfiles.com/

If you can see your file structure using this commercial program then you can choose to use a commercial recovery program such as this or keep trying testdisk.

Looks like that your Data-Partition is still in your GUID-partition table.

Did you already try a boot sector diagnose?
I'd need some infos from TestDisk / Advanced.
You can copy and paste the content from your testdisk.log.

It looked like there was some geometry issues, so I looked at the second drive in the enclosure and found the cyl=364760, Heads=255, Sectors=63, Sector size =512. Started to re-run quick search, ran all night, only at 80% done. If you happen to be online, let me know if you want me just to quit that. I did try a boot sector repair, didn't seem to do much, Windows still sees the drive with two partitions that are un-allocated. Perhaps I should try boot sector repair with the geomtry changed?

Windows still sees the drive with two partitions that are un-allocated.
Would it be possible to upload a screen from your disk management console?
So I can compare it between windows and TestDisk.
Unallocated means easily empty.
The difference is, unallocated or empty disk doesn't contain any partition.
If you have an unformatted partition created (also valid for GUID partition table) your partition will be recognized but unformatted.
Windows will format it, but you shouldn't do it, because you'll override your previous partitions.
Geometry issues are only important if you have an Intel MBR partition.
As long as you use EFI GPT in TestDisk, TestDisk will search each sector for partitions.
This consumes a lot of time.
That's why, if it possible, I diagnose the partition table first (doesn't a matter, is it Intel or GUID partition table).
If any partition is still in the partition table, I'll diagnose the boot sector.
Intel MBR only supports partitions and disks up to 2.2 TB.
Bigger disks and partitions require GUID partitions (GPT
GUID partitions are build in slices.
So that geometry is not important or needed.
Despite that, a boot sector recovery or diagnose is possible.

GUID partitions are a little bit different.
Under windows, you have a MS Reserved partition at the start of your disk and your impotant partition containing data is your MS Data-partition.
Sometimes TestDisk / Advanced lists the MS Data partition but no file system.
In case you can use the menu Type to set it to NTFS for example.
Then you'd be able to use the menu boot and Rebuild BS to have a try to rebuild a boot sector for example.

Here is the screen shot from Disk Manager. I am showing the Disk 1 which is damanged and it's "twin" in Disk 2 for your benefit. Did you want me to stop quick search, and start doing something from Advanced menu right away?
