I have the following setup: *ASUS p2b *Promise Ultra 100 Card with newest BIOS (2.01 Built 27), and newest driver. *IBM DTLA 307030 (30GB, 7200RPM U100) *40pin 80wire IDE cable After running Winbench 99 I had the following results: Disk Transfer Rate: Beginning: 35900 Thousand Bytes/Sec End: 33800 Thousand Bytes/Sec These results are quiet far away from 100MB/Sec as Promise promised (NPI). It is not a matter of life and death, but I would certanly like to get my moneys worth. Does anyone know of a solution for this. Any input is appreciated.

Win2k has no naitive support for ATA100 hard disks even after the release of Service Pack 1.HOWEVER , they did release a HOTFIX for this slight 'oversight': Go to the following site and enter the following :- 1.Enter WINDOWS 2000 under "My search is about:" 2.Check SPECIFIC ARTICLE NUMBER under "I want to search by:" 3.Enter this article number q260233 under "My question is:" GOOD LUCK and email me if you dont get anywhere with Microsoft

OOPS, here is the URL for the Microsoft web site to get your info ;) http://search.support.microsoft.com/kb/c.asp then enter the info in my last post .

Cut the bulls--- please ! There's nothing to do with Microsoft, Asus or Promise, Todays harddisks parform max. 43 MB/s, and those are SCSI 160 drives. Absolute maximum for GXP 40 MB/s, so your 36 MB is normal, although I got 39 MB/s with HD Tach...

Karu , Looks like you are are unaware of the Win2k/ATA100 issue. Don't take my word for it, go check it out yourself at Microsoft's website. Regardless of the throughput you are getting, there is a problem with Win2k running ATA100 disks at ATA66 by default. Microsoft did release a fix for this and I have listed it above in my earlier posts. By the way , why dont you cut the bull . If you dont have anything to post of any use or help , feel free to not post at all . Wether or not you like it , there IS an issue with Win2k and ATA100 disks running at ATA66. PS. if you're going to post some type of data why dont you back it up with a link for people to verify . HAVE A GREAT ONE ;)

Yes, I'm unaware of it, because I have had ATA-66 and ATA-100 disks for already year now and haven't had any problems so far. And I'm using Win2000 without any fixes and patches. Also you are saying that there is an issue running ATA-100 disks at ATA-66 mode ? a'ight ? But in the first question (concentriq) it was Promise ATA-100 controller ! And W2K is using Promise ATA-100 drivers to accsess the ATA-100 harddisk with ATA-66/100+ 80 cable. The fix from Microsoft is more like cosmetical and the issue is not affecting the HDD perfomance. Belive me, it's not logical. If there is problems, they are either HDD problems (like Quantum had) or ATA-66 controller driver problems (Promise, Highpoint). You said, that if I don't have anything to post, then don't. I agree. But I had. My first post was about that "concentriq" actually don't have the problem. You guys are searching from wrong place ! Download Winbench or HD Tach and run some tests, visit the hardware sites or homepage of IBM... Max you can get from clean harddrive is 40 MB/s. So the 36 MB/s is good enough. PS. Sorry 'bout bull____

Whoooaaa!!!! I have been testing my 2 x 30gb IBM ATA100 harddisks, and i noticed that the transferrate certainly has something to do with the FSB.!!! AT 66mhz FSB it could peak at 58mb/sec and at 83,5mhzFSB it was doing 81mb/sec !!!! (Norton diskdrive benchmark and SiSoft Sandra ) .....so what is your CPU/RAM/FSB....etc.etc ??
