September 27, 20205 yr I think I have a problem - after an unclean shutdown the parity check started. Many errors are being reported on Parity2 drive and the estimated finish for the parity check is currently more than 400 days! Zero sync errors, though! Apart from changing the Parity2 drive (my newest drive) does anyone have any advice? The majority of my drives are WD Reds - what drives are people using now to avoid the issues with shingled drives?

It's because Parity 2 has clocked up 7942 errors during the parity check! Anyway, the estimated time is down to ten hours now. Clearly, I need to replace the drive, but with what? Are the WD Red Pro still good, or should I be looking at other models?
September 27, 20205 yr Author Well, here are the diagnostics. It does seem to be simply a very high number of read errors near the beginning of the drive tower-diagnostics-20200927-2234.zip

September 28, 20205 yr Community Expert Parity2 does have a lot of reallocated. I didn't look at the others. Are there SMART warnings for any other disks on the Dashboard?
September 28, 20205 yr Author No, all of the other drives are solid - just Parity 2, my newest drive, which is sick.
