NTFS RAID-0 Recovery with Linux (healthy drives)

cyber_punk · Apr 16, 2015

Hi!
Computer died (motherboard to be exact) and now I have 2x Seagate 320GB SATA drives, that were setup as RAID-0 (I don't know if the RAID was created with BIOS or Windows). I'm trying to mount the RAID array in a Kali Linux environment with both drives in USB3 DuoDockX.
This is where I'm now...
$fdisk -l:

Maybe the wrong device is used? Or the whole disk instead of a

Any help would be greatly appreciated!

Just restore from your backups. It will be a lot less work in the long run.

cyber_punk · Apr 16, 2015

Thank you for your answer but if there would been a backup I wouldn't have posted this question in the first place... Probably.
People don't usually take backups until they need one.

McHenryB · Apr 17, 2015

Everyone who uses RAID-0 needs backups. In fact, everyone with data they don't want to lose needs backups.

Sorry, but I can't think what else to suggest at this point.

McHenryB :

Yes, and everyone knows that, except my friend who didn't!
Anyways, thanks for your time :hello:
