Occasional Core Dump with hot swap USB Thumb Drive

Hello Unix World,
I've been having this issue for the longest time.
Here is my setup
OS: SCO OpenServer 6.0 with mp4, mp3
Server: Dell PowerEdge 840, 800, 2900
USB Stick: Patriot 16GB High Speed, and many other different brands.

Occasinaly while system is running and USB is pluged in the main console will
start looping the following
... Disk Drive: HA4 TC0 LU0 - I/O ERROR 0x4DD13002 HCI Driver
and if unpluged and pluged back in the system will dump core.

Anyone else experience the same problem or maybe know a fix for it?
Please post here. Thank you
