OK, so I have a WD 4100 24TB MyCloud drive. RAID5 Setup. Windows.
The first bay (1) has a red light. The diagnostics say there is a drive fault.
So if I swap it out with a WD Red 6tb HDD, will that fix things? Or will I lose the data on that first drive if I pull it out and replace it?
Thanks!
PS I dont see any data loss yet, how long can I run in this manner and not risk losing my data? Forever, or at least until another drive fails? I guess what Im asking is how long do i have to fix this problem?
Do you have a PR4100, DL4100 or EX4100? Calling it a WD4100 is meaningless, and you don’t have long because if another drive fails you’ll lose all data.
The first step is to determine the condition of the existing drives, which can be done by installing the Get S.M.A.R.T. app from the list below, then running the app and posting the results.
My Cloud OS5 Apps Matrix (Third-Party)
Its an EX4100. Thanks for the link will give it a go

Looks like a false alarm, because none of the drives have any errors. My Cloud OS5 is notorious for this issue. Try rebooting, which should clear the red drive fault LED.
Also, you should create backups, because the drives are quite old.

Wow, looks like you fixed my problem! The red indicator is gone.
I also have these running in an enclosed, dusty area, which probably isn’t helping matters. I’m going to move them.
Yeah, the disks are pretty old… should I go about swapping them out to improve longevity?
Creating external backups is a safer move, because swapping out the old drives for new ones would require multiple RAID rebuilds, which can cause one or more drives to fail without warning.
Concur.
Create a backup. Maintain the backup.
If you roll craps and lose the entire Array; buy all new disks and restore from backup. (probably springing for a newer box while you are at it is not unwise)
