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.... Read more ›

Size Name:1.5 TB
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).

1.0 out of 5 stars
I wish I could give it zero stars - these drives are STILL faulty as of Jun '09!
July 8, 2009
By Zeev Suraski
Size Name:1.5 TB
If you do NOT value your time, money or data - then I highly recommend this drive. For everyone else - STAY AWAY!
As I said in the title, I truly wish I could give this drive 0 stars, and 0 stars for Seagate's support procedures, too (emphasis on procedures - I have nothing against their support reps). I've used dozens of hard drives from many different vendors over the years (including WD, Seagate, Toshiba, Fujitsu), some were better and some were worse - but I never came close to experience anything quite like what I experienced here.
Bottom line - both the original drive I purchased, as well as the replacement drive I received - crashed within a couple of months of fairly low usage. Read on if you'd like the full details.
When I first bought the drive, it was towards the end of 2008, when Seagate was already acknowledging an issue, and began providing new firmwares. I figured that a big company like Seagate won't be able to afford not-to-fix that issue, and decided the buy the drive despite the negative reports. A clear mistake.
Within several days after purchase I started experiencing the same symptoms people were reporting - the drive slows to a halt, disappears from Windows, and also began to 'develop' a handful of bad sectors. Upgrading the firmwares (multiple times, as they were released) seemed to improve the situation - but didn't really. After less than 4 months, the drive died completely failing to spin up and manifesting the dreaded click of death.
It was the first time ever a drive failed on me while in warranty (discounting a drive that crashed when I dropped my laptop a few years ago - which was completely my fault), so it was an unpleasant surprise to receive a refurbished drive in return.... Read more ›
