March 27, 20233 yr Hey guys, I have an array with just two hard drives. Those two being Seagate Exos X16 SAS HDDs. The thing is that one of them has a nice red cross next to it and it says that it's contents are emulated. The parity drive is still keeping it going (thank goodness). But as that's the only drive in the server that's working, it's not safe for me to keep it running. I have requested an RMA from Seagate which looks pretty straightforward, but here's the problem: I don't have an external SAS adapter to just remove the drive and wipe the contents (I need to wipe the drive before I send it in as there's A LOT of data on there), so I have to wipe it from within the server to get it ready for the RMA. I just don't know how to do it. I. have this script to wipe the HDDs, but it requires the whole HDD to be empty from the get-go, so any help to wipe a full HDD from within the array would be much appreciated. Cheers!
March 27, 20233 yr Community Expert Bad connections are more common than bad disks. Attach diagnostics to your NEXT post in this thread
March 27, 20233 yr Community Expert === START OF READ SMART DATA SECTION === SMART Health Status: DATA CHANNEL IMPENDING FAILURE DATA ERROR RATE TOO HIGH [asc=5d, ascq=32] Yeah, that disk should be replaced, if you want to try and wipe it you can with the preclear plugin, first unassigned the disk, then start array, then you can use preclear on it.

Hey, do you mean the pre-clear plugin or the docker app? I found two packages and am unsure which you mean...
March 28, 20233 yr Author Hey, so after unassigning the Hard drive and installing the UD preclear plug-in, I can't see the HDD show up when I go to launch pre-clear, any idea why? The array has been started without the data drive assigned...
March 28, 20233 yr Community Expert Ahh, I believe you need to wipe the partition first, you can do that with the UD plugin.
March 28, 20233 yr Author Just now, JorgeB said: Ahh, I believe you need to wipe the partition first, you can do that with the UD plugin. How would I do that? I haven’t been able to find any reference to this in Unraid.
March 28, 20233 yr Community Expert In the UD settings enable destructive mode, you will then see a red x next to the disk to wipe it.
March 28, 20233 yr Author Yes I saw it now, I am wiping the disk now, looks like it's going to be way a very long time...
March 28, 20233 yr If you can successfully pre clear it without errors, I guess there is no need to RMA it then. That proves you can write to the whole disk ok 🤔

March 28, 20233 yr Community Expert SMART fail is a drive fail - no point in ignoring SMART, that's its only job
March 28, 20233 yr Author Yeah the pre-read conked out, here's the log. preclear_disk_ZL27KHEZ0000C102J0F2_27209.txt
March 28, 20233 yr Community Expert You should only do the clear, no point in running pre or post reads.
March 29, 20233 yr Author So clearing the drive worked, but zeroing yielded errors. preclear_disk_ZL27KHEZ0000C102J0F2_17669.txt
March 29, 20233 yr Community Expert Read errors are expected since the drive is failing, but it should now be clear of your data.
March 29, 20233 yr Author Awesome, thanks for all the help!! I'll reply if there are any further issues.
