X48, AHCI, ICH9R, SATA Hot Plug/Swap not working correctly.

Hello,

So I have a DFI X48-T2R motherboard running XP Pro SP3 + latest updates and all seems to be working just fine.

 

The problem I have is with hot swapping SATA drives inasmuch as if I boot the system with a drive plugged

 

into the SATA port. I can unplug the drive and it disappears from the XP explorer and if I plug it in again

 

the it appears in the XP explorer windows and I can read and write to the drive.

 

However if I boot the system without the drive plug into the port I am using to hot swap then it will NEVER work.

 

Inasmuch as I can plug the drive in but it never appears in the explorer windows or in Disk Manager.

 

I have turned AHCI on in the bios (NONE RAID) and when installing XP I loaded the driver

 

"ICHP SATA AHCI DeskTop ICH93" at F6 time. I have also loaded the latest iata96enu.exe drivers from

 

the intel web site and have install them but the problem is the same.

I have a Dfi NVidia based MB and hot swap works perfectly on it.

 

It just does not seem to happen with intel ICH93

Any ideas please why hot swap/plug does not work?
