Partitions Unrecoverable

#1 Post by sparrowhawk » 28 Mar 2013, 16:53

Good Morning, (at least my time),

My name is Craig. I have a 2tb external hd that Windows stated needed to be formatted. I ran TestDisk. Unfortunately, the TestDisk log file was corrupted, so I am unable to post it.

I have rebooted the Ubuntu Rescue Remix CD that I am using and am running TestDisk again.

In the first batch of analyses, TestDisk reported both:

1) sector doesn't have the endmark 0xAA55

and

2) no partition recoverable


Ideas?

I am running TestDisk again now, but it may be about 10 hours before I have more log data to post.

Thanks,

Craig

Evening,

I have a log to post. The 2tb disk has or had 1 NTFS partition in its most recent incarnation, and that is the partition that I would like to recover or more correctly, be able to access again. I should mention that, while this log does not show it, I also ran analyses after changing the disk head geometry from 255 to 240 and then 16. Both of the results were different but also stated that 'no partition was recoverable'. This most recent analysis was processed in TestDisk run in Windows.

Here is the most recent log:

Please advise as to the next course of action that I should take.

I tried to run Spi**ite and it locked up at about 26% and continued to lock up if I restarted at a location after the original location that it locked up.

So, I thought I would explain how my drive got messed up.

I placed the drive in new external 2 drive dock. The dock has RAID settings which include JBoD and Dual.

I incorrectly inset the dock to JBoD instead of dual, settings explained here:

http://superuser.com/questions/397923/j ... difference


This is how the partition table god messed up, I think. The dock treated the disks as 1 'volume'.

The drive is not a boot drive, it should just be 1 main NTFS partition with data. I'd like to keep the data if possible.

Knowing this and the information from the TestDisk scan, is thereany possible hope of saving the data? Does someone have a next step I can try?

Thanks,

Craig
