Is hard-disk really dead?
Hi guys,
I have a Readynas Pro 6 with 6x Hitachi 7K3000 2TB Drives. It's only been running for about 2 weeks & I've been mostly happy with it. It's running with X-RAID dual redundancy.
From the very beginning, one of the drives (disk 2) was reporting increasing ATA error counts with each reboot. It got to ~40, and I shipped it back to my supplier for a replacement.
When I got my replacement, I put it back in the drive 2 bay. It resynced and all seemed happy. However, as soon as it had resynced, Disk ONE began to report ATA errors. It increased, and a couple of days later, the readyNAS reported it had failed.
Out of curiosity I took the disk out, plugged it into a SATA docking station, and completely removed all the partitions (Windows detected the drive and had no problem playing with the partitions). I plugged it back into the ReadyNAS. It detected it as a new drive and said that syncing will start. However nothing has happened, as under Health it is still reported as dead.
So, I have two questions..
1. Is the drive really dead? I could access it no problem in Windows. What does ReadyNAS consider to be a dead/failed drive?
2. Is there a logic behind a new drive getting ATA errors when there are 6 drives in the bay or is it just a coincidence?
Thankyou,
Rhys

- Also, excuse my paranoia, but after removing the drive from disk 1, under the Health menu it still shows as "Dead" with a flashing yellow light, not "Disconnected". Not sure if this is normal =3
- A resync puts heavy stress on all the drives.
1. The drive probably is dead. Best to hook it up to a SATA port on your PC and check it properly using vendor tools
2. Disks can and do fail at any time.
Btw what version of RAIDiator are you running?
When a disk is removed, it showing as dead is normal. - Thanks mate.
Using 4.2.18.
I've not really got anywhere to hook up the drive to a SATA port, believe it or not. May just be easier to ship it back to the supplier as they are offering.
-Rhys - Strange. I ordered two new 2GB Seagate drives and installed into a 6-bay pro (4.2.19-T4).
These were replacements for 1GBs in the same bays.
Replaced one drive at a time, waited for resync, and then for the Volume to expand. Replaced the 2nd drive, ditto.
All seemed well. 3 days later the Bay 1 reports--without ANY ATA errors, that the drive is DEAD. I connected the drive to an external box on my Mac, ran the SMART tests, and it says it has zero errors. I formatted the drive and its running now in the external box for testing.
In my haste, I had already put in a new (same specs) drive in Bay 1. The NAS shows Resync messages, etc. but Frontview still shows drive as DEAD. Even got emails telling me a new drive was installed, and an Email that the drive sync was complete. Nothing happened after the drive resync, so I rebotted. Now it is syncing Volume C: ... Frontview still says drive is DEAD.
coincidence that Bay 1 only has the problems. New drives, same behavior on Frontview as you??? - new drive, replaced in bay 1 again...2 days later, drive is NOW DEAD. Something isn't right here. Anyone have any ideas??
- Could you please run the "Test Disks" boot option using the boot menu (http://www.readynas.com/kb/faq/boot/how_do_i_use_the_boot_menu)
- It ran, rebooted, and I received a message that the RAID sync finished on volume C. The drive is dead, so I assume the-resync was triggered by the reboot and without the first drive.
- Update. I opened a ticket with support. It appears the problem is with the 4.2.19-T4 firmware. I downgraded to 4.2.17 and rebooted the NAS, and the drive came "alive" and resync'd. Its been running for 2 days now and so far still running. Will wait that magic 3rd day when the other drives failed and see if its hardware of software!
- Hi mate,
Yep, I'm getting similar problems.
Disk 2 was the first to go when I got the NAS but since then it's been disk 1 - so all the new disks just failing over and over. Usually I get some ATA errors first. Just last week I put in a new drive.. all was well after resync. Then a scrubbing and it was still ok. But next day, 40 ATA errors. - Its been two weeks now on 4.2.17 and the "failed" drive is working just fine. The other drives that I was getting ready to return are now running in a Mac server==no errors whatsoever, nada on the disk's SMART stats. Something in the 4.2.19 beta FW. Can't get a copy of 4.2.18 so I can resume my Lion time machine backups. Desperately hoping for a new release soon.
