I’m not being able to use both original drives (WD Red 2TB) on My Cloud Mirror. Can someone help me to do so?
Long story short, I needed to backup files from a 4TB internal HDD and restore this backup to a new drive (both drives are internal to a desktop). The backup time would be huge if I would do the backup to My Cloud Mirror thru Ethernet. So I thought: what if I remove the HDDs from the enclosure and connect them directly thru SATA cables? It would take so much less time… And then I did it. But of course, I had to format the drives (and I did not create an image. Bad idea).
As a result of my journey, I sucessfully did the backup and replaced the intrenal drive. But when I tried to put the original WD 2TB drives back to the enclosure, I was not able to do so. I thought that putting the drives back to the enclosure would be the same as replacing both original drives for new larger ones, that is, the system should be able to format/create its needed file structure from scratch. But it seems not to be the case…
ps: I was able to format both original drives as EXT4. Both are fine and working well when connected to the desktop. The problem is just when I try to put it back to the My Cloud Mirror enclosure.
Below are screenshots of the messages i’m getting:
When I go to Settings->Utilities->Disk Test->Quick Test (I did not do a Full Test), all seems fine:
So, I went to Storage->RAID->Set up RAID Mode. It leads to the self test before creating the RAID, that throws a disk status “Bad” and prevent me from moving on:
Just to be thorough, I’ve checked the system log and it has only the following message for both drives: “The drive x (x=1 or x=2, depending on which drive is being tested) self-checked failed. Contact WD Support.”
After all of that, I’m wondering why I get a “Passed” for both drives on Self Test Results and a “Bad” status for the same drives when I try to Set up the RAID? Anybody can help me to put My Cloud Mirror working again?
ps: I searched this forum extensively before creating this thread. Some threads looked promising to help with my issue, but none of them have worket out. The most simple and promising was this, posted by Danny: https://community.wd.com/t/my-cloud-mirror-replacing-drives-with-larger-drives/143535/7.
If someone can help, it would be much appreciated. Thanks!
