So, ive been running 6x WD15EARS in a Raid 5 on an Adaptec 3805 for about 1 year. Its been a very stable raid - never had any errors at all !
I wanted to expand with two more drives - i bought those, plugged them in, powered on and started the expansion. Seemed to run fine. I was happy a bit too early… a few days later, both the new drives fails within minutes of each other. #¤&¤%/ oh well, got most of the data elsewere - but still annoying. During the next few days, the drives would disappear and reappear MANY times. I noticed that the new drives had a newer firmware version then the old ones.
I therefore bought 6 new 2TB WD Green EARS, so i had 6 identical disks. 2 hours after the new raid was formed (and background initialization was started), the first drive disappeared and reappeared 13 seconds later = raid rebuild started… I deleted the raid, while trying to figure out why these new drives bleep SO MUCH. While doing so, two drives disappeared and reapeared again… This would have resulted in a total raid failure.
I’m fully aware that the drives are non-TLER drives, however, neither were my former drives - and these have had zero problems in almost a year (more than 100TB has been transfered on/off those 6x 1.5TB drives!). Upon my searching for an answer, i came across “WDTLER” - which i also discovered, is now completly useless, because WD has blocked this in their new firmwares… Its like asking “please buy our competitors drives instead”. Im nowhere closer to answer, why these new drives **bleep** this badly.
So where am i now? Im stuck with 6 new 2TB WD drives, that will fail within a day. Unlike the old drives, these are unreliable.
Any way to enable TLER on WD20EARS? I should i just go buy Seagate or Samsung drives instead?
