HDD error message ever since installing a non identical disk ?
hey guys i have been receiving emailed error messages on a disk ever since it was installed (5-6 years ago). The disk is almost identical to the other 5 (4TB) Seagate discs. i.e. 5 x ST4000VN000-1...

Yes, you can just hot-swap the disk.
Netgear does recommend making sure your backup is up-to-date first, as the array isn't protected during the resync. So errors with one of the existing disks during that process will result in data loss.

No. And if it is pre-formatted, you will need to format in the NAS before it will add it to the array.
Personally I do test the disks before I add them (using Seatools in the case of Seagate disks). I run the full generic test, followed by the full erase test (which is a bit tricky to get to with Seatools). I'd strongly recommend doing that with a recertified drive.

a question on replacing the failing drive, with a new drive. (RAID 5)
is it safe to do so even though I am not getting any "degraded raid messages" on the NAS. I know this can have adverse effects doing so on the Synology NAS, does same rule apply to Netgear NAS ?
....or do i simply yank out the offending drive from my nas while powered up and replace it , and wait ? (does new drive need formatted first?)
thanks
