SATA Hot Swap Problems on file server - causes server network connectivity to stop

We have setup a new server with removable SATA hard drives for backups.

The system comprises:

* IBM X3400 Server
* Sunix SATA2100 Internal PCI SATA Controller (SATA hot plug/unplug hardware support)
* Vantec Ez-Swap SATA removable hard drive kit
* Two Seagate SATA hard drives
* Microsoft Windows Small Business Server 2003 R2 Standard

The problem we are having is whenever we hot swap the removable hard drives we lose all network connectivity to the server until we restart it.

All is okay when we unplug a hard drive but when we plug in a hard drive the system seems to freeze for a few seconds and then we can no longer access the server (all workstations report no longer connected to server and server doesn't respond to ping) and server can no longer access network.

Also, at this point, if you try and disable the network adaptor or get network connection properties those windows will just freeze up.

The even logs do not show any issues and we can see no way of restoring network connectivity except a restart (which usually then takes much longer than a regular restart).

Hoping someone can help with whether the problem is due to the IBM server (IBM support was of no help), or whether a different SATA controller card will work, or what else we can do to overcome this problem.
