[kwlug-disc] 4TB drive throwing errors - what's current drive thinking these days?

[B.S.]

The WD Red used to be 5, now 3 - but along has come Red Pro, which has 5.

As do the Constellations.

The WD RE does too, but I've lost track as to whether it's the old model naming line or not, vis a vis the NAS drives (RE has become Red Pro?). Or something.

http://www.wdc.com/en/products/catalog/ notes there's an SE and AE now, too.


There's 500GB free on the drive - I have a feeling that even if some sectors start going bad the btrfs checksumming will cause it to keep hunting for a sector until it finds a good one. Perhaps buying me some time to deal with things.

Just ignore the bit rot lurking behind the curtain. (My guess as to the cause of the files going bad since last week's scrub.)

'course if it's a mechanical / spindle issue ... it's just going to drop on me.

smartctl -H says it's to die within 24 hours. We'll see.
