Hello,

I purchased this week a Seagate 2Tb ST2000DM001-1CH164, firmware CC24.
I did a couple tests with SeaTools and HD Tune Pro 5.0, everything looks normal, the HDD passes all tests... except when I try to actually transfert data from another interal drive to the new Drive, the transfert speed starts around 80Mo/s and quickly fall down to 40Mo/s or even down to Ko/s, until the Drive stop responding, every other file transfer in the computer get slowed down to similar speed (Even between 2 complete separate HDD), and ultimately, the drive disapear from windows until the next reboot.
Could it be an issue with the drive? or the Sata stuff transfert with my motherboard? This is way beyond my knowledge.

My current configuration is:
Proc: AMD Fx 6100 (6 core 3.3Ghz)
Motherboard: Asus M5A97 R2.0
Ram: Corsair 8Go x2
Power: Seasonic 650W 80+
radeon HD6870 VaporX
Hard Drives: Corsair SSD 120Go (operating system)
2x 320Gb Seagate Barracuda 7200.10 (ST3320620AS)
Windows 7

I tried to put the new HDD instead of one of my previous HDD and the problem persist. I am therefore fairly certain this isn't a cable or a power issue.

I also did a HDD Scan SMART report. You will find the result attached to the message. It shows some errors, but I have no idea what it mean exactly.

Do you think I should return the HDD or is there something wrong with my computer?

Thanks, I will. I just wanted to make sure it wasn't an error on my side. I wouldn't want to send back the HDD for nothing.

Are you certain? I placed the new HD instead of one of my 320Gb Seagate Barracuda 7200.10, and the problem persist.
SATA cable, SATA port and power input shouldn't be the problem.

Maybe a SATA controller in the motherboard? It's firmware is already up to date (June 2012)
 
See http://en.wikipedia.org/wiki/S.M.A.R.T.

The ST3320620AS is a 3Gbps drive whereas the ST2000DM001 is capable of 6Gbps. It could be that the SATA interface has problems at 6Gbps. That appears to the reason for the SATA Downshifts. I suspect that when the interface experiences an excessive number of transmission errors, then the drive and SATA controller renegotiate a lower speed.

that's a very good point. Do you think I can force it to work at 3Gbs?
I saw a jumper to force it down to 1,5Gbs.

So the motherboard could be defective... sadly I can't test that unless I have a second HDD or another MB.

Motherboard caracteristics:
Controler AMD SB950 :
6 x port(s) SATA 6 Gb/s
Support Raid 0, 1, 5, 10

I'll use a jumper to force it down to 1,5Gbs and see if it fix the issue.

I was having trouble with two of these in a Linux software RAID1 array (with a third, different drive in three-way replication). Each failed inexplicably, often during RAID self-checks (accessing all sectors), but then would work find after cycling the power and passed all SeaTools checks, etc. I then found this:

http://ask.adaptec.com/app/answers/detail/a_id/17241/~/known-issues-with-seagate-barracuda-7200.14-desktop-drives

"Yes, there is a known issue with the Seagate Barracuda 7200.14 SATA III 6Gb/s drives (models: ST3000DM001, ST2500DM001, ST2000DM001 and ST1000DM003) running firmware CC4G (or earlier). They have been reported as having random failures in RAID arrays.

Seagate has updated firmware that may help stabilize the drives. We recommend flashing the drives to the latest firmware CC4H (or higher) provided by Seagate."

I haven't run long enough to know if this fixes the problem, but it's a good sign.

I bought 6 of these drives and I keep getting randon errors on multiple drives reported too yet that pass the seatools test. So far one hdd has 'failed' and rebuilt twice. The disks get this random error
Unexpected sense: PD = 0:0 - Invalid field in CDB, CDB = 0x4d 0x00 0x4d 0x00 0x00 0x00 0x00 0x00 0x20 0x00 , Sense = 0x70 0x00 0x05 0x00 0x00 0x00 0x00 0x0a 0x00 0x00 0x00 0x00 0x24 0x00 0x00 0x00 0x00 0x00

it seems like you have bad sectors on your drive, this model WD2000DM001 is pretty good model, but Seagate made a lot of revisions, so some could be not the best quality. Try copying one folder at the time, until you copy the most important data and then send it for replacement
