Unknown partition table, wrong capacity
Trying to salvage whatever I can from my friend's 3TB Western Digital hard drive. It doesn't make any terrible sounds that might indicate serious physical damage, for whatever it's worth. Doesn't mount and has an unknown partition table. Attempted a partition table recovery with TestDisk, but it's detecting it as 500GB. How can I get it to see the correct capacity and find lost partitions/data?
Re: Unknown partition table, wrong capacity
I'd need infos about the previous filesystem and your OS.
Current size of the disk might be important too.
Can you upload a screenshot from Testdisk Analyse (current partition structur).

Re: Unknown partition table, wrong capacity
I'm running Arch Linux x86-64 on the data recovery machine, and I believe my friend had a single NTFS partition filling the drive. TestDisk is unable to find any partitions, which I assume is because it doesn't see the right capacity. Maybe I need to manually adjust the geometry? The analysis screen shows it as 539 GB / 502 GiB. Here is the output of my dmesg if it's any help:

Re: Unknown partition table, wrong capacity
some motherboards have problem with 3TB recognition. Your WD hard disk was in external enclosure ? If yes, you have to let it in, because of "on the fly" encryption. You won't find correct info with testdisk until your HD isn't recognized :
You'll perhaps also (not sure, i've to verify) have a block allocation of 4096 instead of 512.sd 11:0:0:0: [sdg] Very big device. Trying to use READ CAPACITY(16).
Re: Unknown partition table, wrong capacity
I would be surprised since it's a brand new ASUS Sabertooth 990FX motherboard. I don't believe he encrypted his hard drive, since he used it for movie storage and plugged it into many computers without problems.remy wrote:some motherboards have problem with 3TB recognition.

Re: Unknown partition table, wrong capacity
Hi kahlil88
It's only a recommendation.
We already have had some cases with encrypted external WD MY PASSPORT disks.
Even the users didn't notice it.
