Recovery Process after Partition Reformatted  Topic is solved

#1 Post by elim » 26 Feb 2012, 00:17

Today I opened up Disk Utility and wanted to reformat one of the partitions on my 2.0TB hard drive.
Originally, I had a 0.5TB HFS+ partition followed by a 1.5TB NTFS partition. (Initially partitioned by OSX Disk Utility as .5TB HFS+ and 1.5TB FAT32 on MBR partition scheme, then brought to Windows and 1.5TB FAT32 reformatted to 1.5TB NTFS)

Unfortunately, when I hit reformat, I accidentally reformatted both partitions to HFS+.
We have sensitive data on the latter half of the hard drive in the NTFS partition. And would like to recover that partition.

We began by trying to fix our partition table using these instructions http://www.cgsecurity.org/wiki/TestDisk_Step_By_Step

During the Deep Scan, at 3% completion, we gave up hope and found that testdisk had already found around 40 different partitions that all could not be recovered. Here is the error message:

Disk /dev/rdisk1 - 2000 GB / 1862 GiB - CHS 3906963456 1 1

The harddisk (2000 GB / 1862 GiB) seems too small! (< 6310817 TB / 5739655 TiB)
Check the harddisk size: HD jumpers settings, BIOS detection...

The following partitions can't be recovered:

[ Continue ]

We then searched deeper within the website and found some instructions on how to undo our reformat to make the HFS+ partition go back to our NTFS partition using this resource: http://www.cgsecurity.org/wiki/Data_Rec ... _partition

Within that process, we are currently at the RebuildBS step and here is a screenshot

Do you have any suggestions for me?

Is the NTFS partition still listed in the current partition table ?
If it's not the case, run TestDisk, Analyse, Quick Search, Deeper Search, use the arrow keys to switch the first HFS+
partition and the NTFS partition to P(rimary). On next screen, choose Write and confirm, if asked, BackupBS and confirm, Quit and restart your computer.

If the NTFS partition is listed, run TestDisk, Advanced, if available, choose BackupBS and confirm, otherwise List.

At this stage, I am trying to execute the List command, but by hitting return, nothing happens. The results here was not from deep scan, will the deep scan can bring different list results? I tried the deep scan a bit, it printed 40 some lines of partition info which I don't know why was so...

I followed the instructions on the website and selected the Advanced command, the partition and type, entered NTFS as my previous filesystem, choose Boot and executed the RebuildBS command. After waiting overnight, I reached the screenshot above but was unable to preform the next step, List.

I don't quite understand this, but it seems like that's the partition info before I accidentally formatted the hard drive.

Before formatting, the partition scheme was:
1st HFS Mac partition with about 500GB
2nd NTFS partition with the remaining space on the 2TB drive (About 1.5TB)

I accidentally hit reformat, but the partition table remains MBR, the current partition scheme is
1st HFS Mac partition with about 500GB
2nd HFS Mac partition with the remaining space (about 1.5TB)

We like to undo the reformatting from HFS and recover all the files in the NTFS partition, and performed the commands from http://www.cgsecurity.org/wiki/Data_Rec ... _partition

What should we do? Do we have enough information to proceed and [Undelete] the partition? Or should we try again or try another method because I am unable to list files?

Can you post the testdisk.log file ? It may help to understand why RebuildBS has failed.

Re: Recovery Process after Partition Reformatted

#6 Post by cgrenier » 28 Feb 2012, 07:52

In the Advanced menu, press 'a' to add a partition starting at 1172137239, set the partition type to NTFS, choose Boot, RebuildBS, List. Does it work ?
If it's the case, it's now time to write the information, choose Write and confirm to rewrite the boot sector, run Analyse, Quick Search, add again the partition and on next screen, choose to Write and confirm to write the new partition table.

I think I understand what you're asking me to do. From the Main screen, I have highlighted Advanced, then hit 'return', then hit 'a', typed in 1172137239 under Cylinder, change the type to NTFS (07), then hit done but did not find options for Boot, RebuildBS, or List.

Once you choose [Done] on this last screenshot, you should be able to select the NTFS partition and choose Boot, List...

Re: Recovery Process after Partition Reformatted

Hello Everyone,

After about a week, I finally recovered my previous partition map!

Here is our abridged story:
We had a 2TB drive with a 600GB HFS+ partition for Mac Backups and a 1.4TB NTFS partition for Windows backup and storage. One morning I accidentally reformatted the entire drive to 500GB HFS+ and 1.5TB HFS+.

We searched online and found TestDisk from cgsecurity.org. We found TestDisk and compiled it for OS X Snow Leopard to use on our Mac. Then we tried using the Analyse tool and Quick Search, but were unable to find our lost partition. We proceeded to the Deeper Scan, but after two nights of searching, I stopped the search, only to find a mismatch of over 40 unrecoverable partitions listed on my Terminal.

We then tried a different tool under the Advanced option, hoping to convert our latter partition back to NTFS, but with no success. Finally, after exchanging several posts with @cgrenier, who looked through our logs, we were able to use advanced commands add a new partition with specific Starting Cylinder values from our logs, a specific Ending Cylinder value (the greatest value in the range of the HD), and a partition type. When Booting and RebuildingBS, we were finally able to List our files.

Lastly, we returned back to the Analyse tool, and although Quick Search could not find our lost partition, we simply added the specific partition again with its type and Starting and Ending Cylinder values. We confirmed and rewrote the partition map, restarted and found our Hard Drive restored completely to it's original form.

Thank you all so much for this wonderful program and your expedient support on this forum.

Sincerely,
Elim Qiu
