That is exactly what I was looking for. Your drive isn't optimized. unmaskirq should be enabled and it should use 32 bit support, not 16.
Thanks for replying.

I've not used hdparm - what am I looking for? This is the output of just running the command on my /dev/hdc device:
[root@nbc-linux ~]# hdparm /dev/hdc
/dev/hdc: HDIO_GET_MULTCOUNT failed: Invalid argument IO_support = 0 (default 16-bit) unmaskirq = 0 (off) using_dma = 1 (on) keepsettings = 0 (off) readonly = 0 (off) readahead = 256 (on) HDIO_GETGEO failed: Invalid argument
If there is something specific I should look for, please let me know - Feel free to email me directly (nbc@cisco.com) and save bandwidth on this list...

Could some of you check your CDROM optimizations with hdparm ? I am wondering if FC3 kernels are optimizing them properly. It might be a udev thing. See/reply to the "k3b: poor CDROM performance... " thread.
Sorry for intruding on your thread.

The latest udev update seems to allow only root access to /media/usbdisk. Although a mortal user can mount the device. Even an ls -l to the mounted dev fails for the mortal user.
