July 22, 2025Jul 22 I keep getting these messages pop up on my server for the cache drive. It says"Unraid Cache Disk Smart Health 187. Warning - reported uncorrect is 28" And the number keeps going up. I ran a parity check. Everything is good. I went into the cache drive self test and it is reporting 0 SMART errors.Why am I getting this message? Is my drive dying?

July 23, 2025Jul 23 Community Expert Yep, it means it's reallocating sectors, so most likely it will fail eventually.
August 5, 2025Aug 5 Author Update:Replacing my cache drive fixed the issue. Also I went from a SATA ssd to a nvme 3.0 drive. I'm not sure if it was the switch from sata to nvme, or if my old cache drive has been failing for awhile, but my unraid system is performing much better now. My VM is snappier and more responsive. Also before the update I was having issues when I would use sonarr or radarr to download new movies or shows in 4k. It would bring my system to it's knees and take forever when importing into Plex. Doesn't do that anymore.
