N5200 Pro and Seagates (750GB 7200.10) ST3750640AS

I ordered 5 OEM ST3750640AS from Newegg and 2 were physically dmaged when I received them. I installed the other three in my brand new N5200Pro.

My "Disks Information" page shows each drive with an O.K. status. When I click on the O.K. to see the status I get the following

Tray Number 1
Model ST3750640AS
Power On Hours 35 Hours
Temperature Celsius 44
Reallocated Sector Count 0
Current Pending Sector 0
Raw Read Error Rate 12539647
Seek Error Rate 3316398
Hardware ECC Recovered 200912133

Tray Number 3
Model ST3750640AS
Power On Hours 35 Hours
Temperature Celsius 41
Reallocated Sector Count 0
Current Pending Sector 0
Raw Read Error Rate 4645109
Seek Error Rate 3347229
Hardware ECC Recovered 199423014

Tray Number 5
Model ST3750640AS
Power On Hours 35 Hours
Temperature Celsius 43
Reallocated Sector Count 0
Current Pending Sector 0
Raw Read Error Rate 102570698
Seek Error Rate 3280735
Hardware ECC Recovered 45916580

An hour later I have an average increased in Seek Error Rate and Hardware ECC Recovered of 14173 and 15562025 respectively. My change in Raw Read Error Rate for drives 1, 3, and 5 is -230301353, -230387292, and 15664538 respectively. So drives 1 and 3 decreased and drive 5 increased.

I am running V2.00.04 firmware and the following modules

Module Management
Name Version Description Enable Status
PERL 2.00.01 Perl Programming Language Yes
SSHD 2.00.00 Enable SSHD Yes
SYSUSER 2.00.02 Add sys user Yes
UTILS 2.00.01 Utility Programs Yes
SQUEEZECENTER 2.00.01 SqueezeCenter Media Server No

I've read in this forum and the usersgroup forum that Seagate may not want other manufacturers to be able to understand this data, but I don't see many people complaining so I wonder if this is normal or not. Since 2 of the 5 drives had physical signs of damage I am little worried about the state of these three drives.

Thanks and I apologize for the long post.

Your discs seems to be ok. The important information to look at is

Reallocated Sector Count and Current Pending Sector

If these counters are going up it is an indication, that the drive will become a problem. Depending on the speed the first counter changes, earlier or later.

If this counters are 0 your discs are ok.

Thanks Mike. I was a little freaked out. After reading about it, your comments make me feel a lot better.

Take Care,
Alex
