@openit said in How can we recover data from Hard Drives were on RAID 10 without controller?:
I have a QNAP NAS box, which started giving trouble of stuck at System Booting, as opened a ticket with Support, they conclude that it is hardware level fault.
Not sure if I can do something on Device without sending the device to QNAP, like booting from Linux on USB etc. to access the drives from there.
About recovering the data on hard drives from this NAS Box, which is configured with RAID 10 on 4 SATA Hard Drives.
Is it possible to connect these SATA hard drives to PC and recover data?
If yes, I will boot Fedora Live CD, and connect one by one hard drives, at first to check if hard drives are Okay, by looking at SMART or other tools in Fedora. Once done with Hard Drive checking, I may want to connect to Windows PC and get data.
Again, since it is RAID 10, it will have a pair (for striping), is it HDD 1 and HDD 2 will be pair one ? HDD 3 and HDD 4 will be pair 2?
Once I connected, how can I combine data from HDD 1 and HDD 2 as singe drive to get the data? with any software?
Appreciate you kind response!
Well, you won't be able to do anything with the device itself.
If you are a LVM and MD master, it's possible to read data from those drives. Most techs are much more likely to just erase everything than actually get data off of them.
