Mokkisjeva Posted May 5, 2020 Share Posted May 5, 2020 Hello, (Hope I'm in the correct section of the forum) I'm starting to get errors on my WD Red 8TB, and wondering how critical it is for me to replace, as in.... what time frame are we talking about here. Raw read error rate 0x000b 100 100 016 Pre-fail Always Never 0 2 Throughput performance 0x0005 131 131 054 Pre-fail Offline Never 116 3 Spin up time 0x0007 148 148 024 Pre-fail Always Never 454 (average 432) 4 Start stop count 0x0012 100 100 000 Old age Always Never 20 5 Reallocated sector count 0x0033 100 100 005 Pre-fail Always Never 19 7 Seek error rate 0x000b 100 100 067 Pre-fail Always Never 0 8 Seek time performance 0x0005 128 128 020 Pre-fail Offline Never 18 9 Power on hours 0x0012 096 096 000 Old age Always Never 29766 (3y, 4m, 23d, 6h) 10 Spin retry count 0x0013 100 100 060 Pre-fail Always Never 0 12 Power cycle count 0x0032 100 100 000 Old age Always Never 20 22 Helium level 0x0023 100 100 025 Pre-fail Always Never 100 192 Power-off retract count 0x0032 064 064 000 Old age Always Never 43353 193 Load cycle count 0x0012 064 064 000 Old age Always Never 43353 194 Temperature celsius 0x0002 162 162 000 Old age Always Never 37 (min/max 24/47) 196 Reallocated event count 0x0032 100 100 000 Old age Always Never 19 197 Current pending sector 0x0022 100 100 000 Old age Always Never 0 198 Offline uncorrectable 0x0008 100 100 000 Old age Offline Never 0 199 UDMA CRC error count 0x000a 200 200 000 Old age Always Never 0 I'm also wondering how I can find out why this drive in particular is being used so much more than any of the others.

JorgeB Posted May 5, 2020 Share Posted May 5, 2020 A few reallocated sectors can be OK, if they remain stable, and as long as there are no read errors now. Quote Link to comment
Mokkisjeva Posted May 5, 2020 Author Share Posted May 5, 2020 So what is a "few" in this case? Sure, if I see a rapid increase then obviously I would have to do something soon, but you say they can be stable which ofc makes me want to believe the drive might be still be good for some time. Assuming read errors are where I would stop using the drive all together? Quote Link to comment

For me up to low double digits reallocate sectors are just "a few". 6 minutes ago, Mokkisjeva said: Assuming read errors are where I would stop using the drive all together? If the dive fails an extended SMART test or gives read errors on parity check it should be replaced now, independent of how may reallocated sectors there are. Quote Link to comment
Mokkisjeva Posted May 9, 2020 Author Share Posted May 9, 2020 (edited) Update: After 4 days the reallocate sector value is now 60, so it just keep going up at a steady pace. New drive on the way and I'm currently moving files off the disk. What I'm wondering is if there's a chance a cable or mb port could be the issue? It's just so weird it happened after upgrading HW, like first reallocate sector warning came day after new rig. If so, would new cable/port and a preclear "reveal" all the bad sectors?

Cable/port won't make any difference (unless there's a problem with the power, bad power can in some cases cause pending/reallocated sectors), preclear or a full write might or not mark/reallocate all bad sectors, difficult to say.
