Hi,
Im new to this forum stuff but Ive been trying for almost a year to get more than one hard drive working in my computer.

I have an Asus P5K-E Wifi, which has the IHC9R controller,
and also has the JMicron JMB36X IDE controller which also has 2 esata ports (works fine but can slow right down from 100 mb/sec transfer rate, to 12 mb/sec after about 15-30 seconds of transfer with large files, is this normal), which is set in AHCI mode, to utilize plug and play hard ware.
Also have a dvd writer connected to IDE.

Im running a 500 gb seagate hdd as my boot disk, and Ive tried with multiple hard drives.
Both in IDE mode and AHCI mode in XP, got it to work for a short time but then just dissapeared,
And have also tried in Windows 7, but the bios, would not even recognise the hdd.
The hdd are a 1.5 tb seagate, (working firmware CC1G), and a 500 gb Western Digital Caviar, both of which work fine in a External Hard disk enclosure.

Any suggestions, or if anyone has experienced any problems similar to this it would be much appreciated.
Thanks Sam
