Recover 2 partition from RAID 0

#1 Post by Pepinen » 29 Nov 2015, 22:19

Hello i think cloud be anyone can help me. i Have 2 Raids 2x3.5 sata 2TB raid 0 and 2x3.5 3TB Raid 0.

Mi mobo have a problem and they reset the fractory defaults, the 3 of 4 hard disk says non raid disk.

I have this problem before and then erease the raid or raids create the same raids and execute testdisk, they do a quick scan and detect de partition, write the partition and reboot.

The both raids recover all data.

Now y have the same problem but the testdisk not recononice the gpt partition, on 6TB raid says that que hard drive is small because they detect a partiton with more capacity.

¿anyone can help me please?, i need to recover one of 2 rais because 4TB raid is a backup from 6TB raids and both have problems with testdisk.

i tried to use a getdataback or reclaime fire recovery. Both detect the data but only recover corrupts files.

Here is the log from 6TB raid:

Check the harddisk size: HD jumpers settings, BIOS detection...
The harddisk (6001 GB / 5589 GiB) seems too small! (< 12 TB / 10 TiB)

Did you use TestDisk 64bit?
TestDisk 7.1WIP 32bit is recommended.
Under disk selection select Disk /dev/sd' (a,b,c, etc..) instead of PhysicalDrive.
TestDisk 64bit is only recommended on genuine 64bit environment like Itanium.
There is also a note:
Windows 64-bit Use only on systems lacking WoW64 as some features are missing
Can you repeat your diagnose and copy and paste the content of your testdisk.log into your next post?
