De-bricking script errors

I’m attempting to resurrect a bricked MyBookLive (2TB), using the popular de-bricking script. Using a USB enclosure, connected to my Win7 laptop (Lenovo W520), via WMware Workstation / Ubuntu. Here are the errors:

mdadm: /dev/sdc1 appears to contain an ext2fs file system

mdadm: /dev/sdc1 appears to be part of a raid array:

I’m a complete linux novice, and have no idea what’s going on here. Any insight would be well appreciated!

I had this happen to me after the script failed. Reboot your computer to free up md0 and try again :wink:

I had to use SystemRescueCd (x86, version 4.4.0) to run the script. mdadm in ubuntu 16.04 refuses to create raid array of partitions, which is required. you also probably don’t have compiler installed and even then the swap.c would need to be edited. using sysresccd is just so much easier for this task.

or you can edit the script to use md1 (or 2,3,4 etc.) instead of md0 and rebooting the pc.
