Hi!
Short version: Raw_Read_Error_Rate has creeped up to 1 on a new WD Red after running SMART tests and badblocks. RMA the drive?
Long version:
System:
Built the system, original PSU was DOA, ran memtest for 48 hours, memory checked out. Then ran SMART tests. My testing went something like this:
For each disk:
$ smartctl -t short /dev/adaX
$ smartctl -t conveyance /dev/adaX
$ smartctl -t long /dev/adaX
Then:
$ sysctl kern.geom.debugflags=0x10
And for each disk:
$ badblocks -ws /dev/adaX
$ smartctl -t long /dev/adaX
$ smartctl -A /dev/adaX
First time I did this everything went fine. Disks were staying around 30 deg C, they weren't agressively spinning down, no errors reported. SMART values all looked sane. (The runtime for the long tests and badblocks seemed to vary between the drives, but I'm guessing this is due to slightly different rotation speeds?)
I rebooted and repeated the SMART and badblocks tests again. Tests passed (again), but I noticed that Raw_Read_Error_Rate is now 1 on one of the disks. This disk is the "oldest" of the bunch: I bought the drives over a period of ~2 months and was playing with FreeNAS before I had all the drives.
Should I be worried? I'm running the long tests again on that drive, and am thinking of running badblocks again. The system has been on for several weeks straight at this point, but besides testing it has been unused (been really busy... :/). Thoughts?
(I tried searching the forums for Raw_Read_Error_Rate but just found a lot of people posting their smartctl output... sorry if this has been asked many times before...)
