Problem with high FSB and HDD

Edit: ARgh Sorry I postet at Intel Motherboards

Hi, perhaps you remember my old posting. My Abit KD7 Raid works again at 200MHz FSB.
But there is a Problem with 200MHz FSB.
I have 2 HDDs, one WD1200JB as Master and one WD400BB als Slave at the same connector.
With 200MHz FSB the PC is primestable for some hours. But when i download a zip-file and extract it the files are corrupt. When i want to move the files into an other folder the files don't get moved But on the other HDD there are no Problems with these files, it works great on it.

So i thought it may be that UDMA33 could help but it didnt. And i have set the PCI Timer to 42 but this didn't help.
Now its on you to help

My System

Abit KD7
1800+ T-Bred B JIUCB
512 Mb TwinMos PC3700 BH5
Antec 380W True Power
WD1200JB
WD400BB

this must be the components that have to do with this problem.

P.S.: sorry 4 my bad english

I guess you need to use a multiplier to get the PCI speeds more close to 33MHz...
My other guess is the memory...

i don't think that the memory is at the end, i put it to 3V to test but it didn't help.

And if it was the Ram the other HDD would make Problems too
