@trurlYes. I have notifications set up so I can stay on top of the server status. @Frank1940 weighed in above regarding whether or not I should add my new 10TB drive or not. Do you agree with them or would you recommend just adding it to my array? I'm not hurting for space yet.

@trurl Since it did not throw any errors, do you think the disk is probably fine after the rebuild? Or, would you recommend replacing it anyway?

I followed these steps: Stop Array, Unassigned the disabled disk, Restart Array, Stop Array, Reassigned the disabled disk. A parity check/sync completed with 0 errors and the disk is green again. I ran an extended SMART Test and the Current Pending Sector attribute returned to 0. Offline uncorrectable is also 0. I have also received my new disk. Should I proceed with replacing this disk or would it be advisable for me to add my shiny new 10TB to my array? Thanks for your help.

The disabled disk is 10TB - the largest disk I currently have on hand is 8TB.

Thank you for your fast reply, trurl. My spare disk is in the mail and will be here in a couple days. I have other spare disks lying around but none that are the same capacity as the disabled one. Diagnostics are attached.

Hello, I know this is a common issue that has been discussed frequently on the forums. However, after reading through those threads, I am still confused as to what my best course of action is. The situation: recently, a disk in my array was disabled. I am not sure why, but after running an extended S.M.A.R.T. test I noticed the "Current pending sector" attribute had a Raw Value of 96 which, as I understand, could potentially be a cause for concern. I am posting my S.M.A.R.T. report for that disk. Any and all help would be greatly appreciated. SMART_Report.txt
