Re: Western Digital WD20EARS "Advanced Format" - 4k sectors needed

I got 2 WD15EARS around 15 months ago and last month, one of them started failing so I removed it from the raid array.

Re: Western Digital WD20EARS "Advanced Format" - 4k sectors needed

FWIW, my 5x WD20EARS are still working.

Hours alive: 6425, 1908, 6825, 6775, 6391 . The highest LCC is 152801.

DEV	EVENTS	REALL	PEND	UNCORR	CRC	RAW	ZONE	LCC
sdb1	6773605	0	0	0	2	0	0	83749
sdc1	6773605	0	0	0	0	0	0	127634
sdd1	6773605	0	0	0	0	0	1	152801
sde1	6773605	0	0	0	0	0	1	59909
sdf1	6773605	0	0	0	0	60	8	
sdg1	6773605	0	0	0	0	0	0	82869
sdh1	6773605	0	0	0	0	0	5	

(the ones with LCC are WD20EARS)

1LordAnubis start another topic next time please.
As for EARS-EARX drives they are pretty good in terms price/GiB. If you are afraid from LCC inceasement, you can use WDIDLE3.exe and set it to "off"

1-st is 1 year old ( was untouched until 2 weeks ago )
2-nd is 2 weeks old

And for "AF - 4k sector" parted and gptdisk are fully aware of it from quite some time .. so i may say those drives are not bad at all
