Re: A Colossal HDD Failure

Ugh another sick 2TB disk

The saga continues:

 5 Reallocated_Sector_Ct  0x0033  051  051  005  Pre-fail Always    -    1050
 9 Power_On_Hours     0x0012  095  095  000  Old_age  Always    -    40489

193 Load_Cycle_Count    0x0012  001  001  000  Old_age  Always    -    242918
196 Reallocated_Event_Count 0x0032  050  050  000  Old_age  Always    -    1075
192 Power-Off_Retract_Count 0x0032  046  046  000  Old_age  Always    -    65535
197 Current_Pending_Sector 0x0022  100  100  000  Old_age  Always    -    0

This is one of three identical disks configured the same way, those load cycles were self imposed, not from power savings...

The disk is currently *very* slow and is slowing down the RAID5 that it's part of right now. I wonder if I should replace it sooner than later, though if I can find a cheap replacement I should buy one now?

Re: A Colossal HDD Failure

Speeds went back to normal once more...but with a few more bad.

 5 Reallocated_Sector_Ct  0x0033  051  051  005  Pre-fail Always    -    1055
 9 Power_On_Hours     0x0012  095  095  000  Old_age  Always    -    40513
 12 Power_Cycle_Count    0x0032  100  100  000  Old_age  Always    -    101
193 Load_Cycle_Count    0x0012  001  001  000  Old_age  Always    -    246393
196 Reallocated_Event_Count 0x0032  049  049  000  Old_age  Always    -    1080
192 Power-Off_Retract_Count 0x0032  046  046  000  Old_age  Always    -    65535

Re: A Colossal HDD Failure

Which disk will die first...the above disk or one that has

 5 Reallocated_Sector_Ct  0x0033  200  200  140  Pre-fail Always    -    0
 9 Power_On_Hours     0x0032  001  001  000  Old_age  Always    -    75482
 12 Power_Cycle_Count    0x0032  100  100  000  Old_age  Always    -    361
192 Power-Off_Retract_Count 0x0032  200  200  000  Old_age  Always    -    266
193 Load_Cycle_Count    0x0032  001  001  000  Old_age  Always    -    628758
196 Reallocated_Event_Count 0x0032  200  200  000  Old_age  Always    -    0
197 Current_Pending_Sector 0x0032  200  200  000  Old_age  Always    -    0
200 Multi_Zone_Error_Rate  0x0008  200  200  000  Old_age  Offline   -    2

And be d**ned if I have to get a SMR disk because they're cheaper...though I'd think the SMR disk might work fine for the PVR.

Re: A Colossal HDD Failure

Interesting. Seems the flakiness is related to temperature... hmmm....

Possible bad connection causing sanity checks to fail?

Re: A Colossal HDD Failure

Seems like it's a specific temperature. Don't know. Also the drive appears to "work" ... just very slow when the ambient temperature is, say, above 70F or so... Below that, it works perfectly.

Re: A Colossal HDD Failure

BOOTED! Well, normally that's a good thing...except when it got kicked from my disk array! Just noticed my RAID was running degraded.

Looks like the disk went to greener pastures. Sort of. It's still "working" (and SMART says "PASSED") alas it's probably time to say goodbye... It only had ~40000 hours on it when it finally got the boot, sigh.

I just hotswapped a not-so-great condition WD RE4 for the very sick Toshiba disk (manufactured late 2014) as a stopgap. Currently going through recovery at the moment....I think it will take about 8 hours. The WD RE4 was a RAID1 mirror to another 2TB disk, and that RAID1 was the backup to the current RAID5 - the mirror device was a better lower hour disk and I figure that if I lose the contents of the WD and the main RAID5, I'd still have that younger disk left over as the remaining backup and not gamble whether the WD RE4 was healthy.

I still need another disk real soon, and hopefully I can boot off the WD RE4, though probably will need to reinstall grub onto the disk and array...

Re: A Colossal HDD Failure

Bah. I moved that sick Toshiba disk to another machine and ran a nondestructive write badblocks run...
Came through clean - no problems reading or writing!

Same SMART error log showed up as on the other machine, but the drive worked just fine. Wonder if I should trust using this disk anymore. Currently running it RAID1 with the other array I broke up to put another disk in the main RAID5.
