My four brand new RE4 WD5003ABYX (FW 01.01S01) drops randomly from RAID at Adaptec 3805 (the newest firmware).
It drops at 1,5Gb/s mode too.
I replaced cables, and did test with fresh operating system (win7 32 bit). Nothing helps.
How it can be? RE means Raid Edition. I had the same problem with desktop drives so I switched to enterprise disks.
What can I do now, please help?
Best regards Chris

Maybe you should try contacting WD's Technical Support about this. You can do so either by phone or email.

Nesvic - thanks for your advice, I did as you said.
I have also tested cache mode on/ff. NCQ on/off, RAID 0, 1, 5. It still happens :-(
Let's hope WD support will help me :-)

I discover TLER in my RE4 is set to 7 sec. My old ES.2 is set to 7 sec and it worked fine for years.
My three Barracudas desktop drives ST3500418AS (FW CC35 and CC37) with TLER set to 0 sec also works fine.
Two very old Barracudas 7200.7 ST380817AS never dropped from RAID with this Adaptec.
One IBM-ESXS MAX3073RC (73GB, 15k) as SAS drives is working perfectly.
I think I can say that my controler is not the problem here.
Can you imagine how I was suprised seeing RE4 dropping all the time (one drive/hour).
Seller refused me to back WD drives. Am I doomed with them?
I hope not :-)
Seems other drives got similar problem and WD resolved that.

In the meantime, I tried to check out IntelliPark status with wdidle3.exe. Tools reported that this feature is disabled on all disks. So it is not the cause of error.
