1.0 out of 5 stars Works fine after applying firmware update, November 2, 2008

By	John Smiley (Seattle, WA) - See all my reviews (REAL NAME)

Update: I wrote this review before a firmware update was made available and my comments reflect the situation at the time. When the updates were made available, I flashed my 5 drives and they've been working fine ever since. I'd change the rating to a 4 star if the editor allowed.

I and many others have been experiencing serious problems with these drives including:

* dropping out of RAID configurations for no apparent reason
* being ejected from a RAID configuration due to read / write errors
* freezing for up to 30 seconds

These problems have been reported on Linux, Vista, XP, and OS X and appear to be related to how the drives flush their write cache. In many cases, the drives work fine for days or weeks before problems appear. In my case, I bought five of these for my Qnap TS-509 Pro and they worked great for about two weeks under various read / write loads. Since then, I've had all three of the problems mentioned above on different drives and they are growing progressively worse. The latest problem was three of the five drives disappearing from the RAID5 volume while I was attempting to copy the files to a different NAS.

A work-around that has been successful for some is to disable the disk write cache. Other than the obvious performance penalty and reduced lifespan this causes, some systems do not provide a means of disabling disk write cache (such as the Qnap).

5.0 out of 5 stars I believe problems are resolved !, December 6, 2008

By	Honest Guy "geffroman" (Huntington Beach, Ca USA) - See all my reviews

NEVER SHOULD HAVE HAPPENED:
I've watched the issue with these drives carefully for about 2 months. It looks like Seagate solved the problem and that a vocal few were ever really affected. By few I mean relative to the thousands sold. And I am not defending Seagate. This whole fiasco was unacceptable.

MY SYSTEM:
I picked up 8 of these drives. I'm running them in 4 separate DLink DNS-321 RAID boxes. I've copied about 4TB of data back and forth across them for days. My only firmware update needed was for the DLink so that it could properly handle the new 1.5TB drives.

In the end I believe all is well with both the drives and the DLink DNS-321. I will of course update this review immediately if I see any problems.

PERFORMANCE:
We are able to watch movies from this drive arrangement on 3 computers simultaneously across a 100mb network from the same drive while adding new files to the drive from a 4th computer.

This means I can be adding movies unattended to the system while watching an Epic Man movie on the plasma in the living room... while the kids are watching Monsters Inc in the bedroom... and the wife is off watching some chic flick in the Den. :)

The combination of DLink and these 1.5TB drives is fantastic and seems as stable as the WD 1TBs I was using previously.

PROPER DIAGNOSIS:
Don't confuse your drive DIEING after a week with the previous firmware problems of this particular drive. Blame the vendor that shipped the drive like it could bounce !

ON A SIDE NOTE:
I will say I am sick of Amazon, Tiger and other vendors shipping hard drives like they are indestructible ROCKS. Even if they arrive working, this inadequate packaging is certainly taking years off the life of our drives. One of my 8 arrived DEAD as a brick thanks to this nonsense. I am furious about this issue !

Will it take a class action to stop this behavior of guaranteeing future drive sales by damaging todays drives through deliberate mishandling of our purchases ?! Wake up AMAZON ! Wake up TIGER !
