how to recover data from failed RAID1 configuration of 2.5" enclosure?
-
I built a RAID 1 hard drive using a 2.5" enclosure. after 10 years, one of the drives failed because that indicator light blackened. another hard drive seems good. Now my PC workstation can not recognize this RAID 1 hard drive. So my only way is to pull out the two hard drives and read them from an adapter. any experience to share in this scenario?

Is it a hardware or software RAID? Linux can mount a single drive of a mirror, been quite a while but I used mdadm to mount it.

it is hardware RAID. I initialized and use it on Windows 10.

- Replace the faulty disk and rebuild the RAID "array" 2) Yank out the faulty disk and change the connection from RAID to single disk

If it is really a HW RAID controller, you should enter it's BIOS and rebuild from there (be careful which one mirror onto which one if asks) Read the manual :) [serverfault](https://serverfault.com/questions/907351/replacing-a-drive-in-a-mirrored-set-raid1-how-does-it-know-which-is-primary) [superuser](https://superuser.com/questions/610315/how-does-raid-1-determine-which-drive-should-act-as-the-source-for-a-rebuild) SW one example: [How does Rebuild in host-raid RAID-1 works?](https://serverfault.com/questions/700668/how-does-rebuild-in-host-raid-raid-1-works)

The trickiest bit is figuring which drive is the dead one. With SSDs they don't whir anymore and they stopped putting lights on them so a dead one mimics a live one really well. It's possible connecting a new drive exactly like the old one will trigger the array to rebuild itself on boot. Pretty much replace the bad drive and fiddle with RAID in BIOS/controller though.
