Why this disk is too slow.BootVis say to me this disk has thw Write cache disableb.How can i Enable this cache?

Not sure if this covers WD Raptor but worth a shot.

Write Cacheing is a firmware issue. It's something the engineering samples sent out for preview had off, thus turning in some poor performance on real world tests. Sounds like you might have bought a pre-release raptor as opposed to a retail one

P-X

 

[microAmp]

I couldn't find any firmware updates for you, maybe if contact one of the AnandTech Staff (if they still have it) or Western Digital they might give it to you.

I have two in RAID 0 and it's sweeeeeeeeeeeet!!!

I think you got a BETA version, was it OEM/Retail, and where did u buy it?

 

[Viper96720]

I would contact western digital see if you can get a firmware update or get the better drive. I don't think your drive should've been sold.

 

[chris75]

Hmm I have made a test in PcMark2002 and I have only 775 Pts. .My next Wd Caviar 800JB has 1068 Pts. Maybe my controller HPT347 is not good for this drive.
MotoAMd: I dont have this field in Properties uncheck Write Cache .Maybe this driver does not support Write cache.

 

[Viper96720]

There was two versions
pre release notice the low scores
Production version scores much better
We think yours is a beta version. I would contact western digital maybe they can tell what version you have by a product code.

I have the same mobo, with 2 WD400JBs in RAID 0, and Sandra gave me the same crap. That section under policies is grayed out. However, under 'SCSI properties', there are two options: 'Disable tagged queueing' and 'Disable synchronous transfers'. Anyone know what these are for? Perhaps this could be the key. Sounds like they would work anyway. Hey Chris, when you got the motherboard, what version of the BIOS did you have? I had a old one, but couldn't get the RAID drivers to work right with a fresh install of XP. I had an old BIOS (when you flash it, the 374 gets flashed too), but it said I could do RAID 5, which would figure because that chip is huge, way bigger than the one on my Adaptec 1200A, the same size as the one on the cards that do do RAID 5. Just curious about that last part, Thx

To enable write cacheing. Click my computer then right click on the drive and select properties. Select hardware highlight the drive and click properties. Click policies and optimize for performance

Happy Cracker: When I buy his Mobo i have this bios AT72B7.exe from 9/9/2002 , now Im working on latest bios version.I think also this is problem with firmaware.Today I go to my friend and I must test this HD on another SATA controller.

There is no way you ended up with a preproduction drive. None at all. Even if by some complete freak accident, you did, you would know right away by the drive label with the large BETA SAMPLE stamped on it. There are multiple places that write cache can be enabled and disabled, the drive, the controller, and windows, though it is more than likely that you can't use any of them to actually change the setting. I doubt there is anything wrong with the drive. It's probably the piece of junk Sandra benchmark that is messed up. Try using something like ATTO which gives more consistent results.

sandra is a piece of crap drive benchmark is the story.

I believe we told him the same thing over at . Storage Review

Big Thanks for any Answers.
Im going now to shop to change this drive.Anyone know how must be number in firmware Ver. with Write cache Enabled or when this drive must be built (date)
This Is My test in ATTO Disk benchamrk

ATTO Overlapped IO WDRaptor

For comparison next next is from My old WD800JB

ATTO Overlapped IO WD800JB

Next test IO comparison ATTO Disk benchmark
ATTO IO Comparison WDRaptor

Next test from HDTach 2.61

HDTach 2.61 WDRaptor

I dont know this is good preformance or not.
