SAMSUNG HD753LJ vs. WDC WD7500AACS

Featured Replies

Hi,

 

just a note.

 

The Samsung 750GB HD753LJ don't report temperature when connected to my Promise SATA300 TX4 controllers.

 

The Western Digital 750GB WD7500AACS do!

 

The Western Digital 1000GB WD10EACS report too!.

 

Regards

Harald

 

It may be a firmware issue in the Promise controller.

I just had a drive that stopped reporting temperature. In my case it was a drive problem. If I swap the drive to different drive slot, it is still the same drive that does't report temps. My drive is a Western Digital WD5000AAKS 500GB. I have two of these drives and only one of them just started to do this. If someone knows what would cause this please let me know.

Just an update on this one.

 

I read some information about smarctl here in the boards. Issuing:

 

/boot/smartctl -a -d ata -s on /dev/sda

 

to my Samsungs started them showing temperature. Is there a way to issue this command after "go" and "spin-up" for all drives?

 

Thanks

Harald

 

I think I was the one that posted that.

 

I put this at the end of my go script:

############################
#
# Enables SMART on Samsung disks
# SMART is not enable by default
#   on these drives
#
/boot/smartctl -a -d ata -s on /dev/sdf
/boot/smartctl -a -d ata -s on /dev/sdg
/boot/smartctl -a -d ata -s on /dev/sdh
#
############################

 

I haven't actually rebooted yet to see if it works, but it should!

 

EDIT: For the purpose of the original post, I'd prefer the WD AACS drive. The AACS drives are their green power ones.

I just installed a WD WD10EACS in my server. The temps down my drives show how efficient it is, and atm I'm currently writing from DISK1 to DISK6 (no parity atm! Waiting for the 2nd 1TB disk to arrive!!! its scary..) :

DISK1 - Samsung HD401LJ - 36

DISK2 - Samsung HD401LJ - 32

DISK3 - Samsung HD401LJ - 32

DISK4 - Seagate T3200827AS - 31

DISK5 - Seagate T3200827AS - 34

DISK6 - WD WD10EACS - 28

DISK7 - Seagate T3200827AS - 38
