Hello,

i have a NAS using raid10 under ubuntu 12 x86.

one of my disk has an I/O error and it seems the error has been mirrored to the other HDD.

In order to avoid any issue (as my RAID10 is not accessible) i'm looking for a way to recover all my data from destroyed RAID10 and to save them to my local computer.

how can i do that using my ubuntu 15.10 ? if possible (as my RAID 10 has 4 HDD) i would like to avoid to destroy original data from RAID.... may be only 1 HDD has a failure.

i can connect each disk to my USB port but partition are: swap, RAID member, etc... and i do not know how to do next step.

thx.
