One of the drives in my EXT2 Ultra configured as RAID 1 just failed. Luckily, it should be covered by the 3 year WD warranty (it’s a WD drive). However, I have no idea how to tell which is the drive that failed, since they’re both identical. I also don’t want to try and remove 1 at a time, because I don’t know what that would do to my RAID configuration and, ultimately, my data, which is what I am trying to save the most.
Does anyone know how to identify the drive? According to the My Cloud OS 3 software, Storage, Drive Status page, it’s Drive1. Is that the one on the left or on the right when I am facing the EXT2 Ultra?
Also, say I know which disk it is and I pull it out to get the serial number and send to WD. Should I turn the NAS back on? Will it automatically convert to RAID 0 and I won’t lose any data? And once I get the replacement disk, can I pop it in and then, turn the configuration back to RAID 1, also without losing data?
LOSING MY DATA IS THE ONE THING I CAN’T AFFORD.
Thank you in advance.
UPDATE: After posting this, I opened the EXT2 and noticed the disks are labeled. 1 is on the left and 2 is on the right. I also came up with another idea to confirm… Through the software, I can get the serial number of the good disk. I can then pull both out and check with one has a different serial number on the back. That should be the bad one. The rest of the questions remain.
