Creative I/O USB2 external case

[oldgrey]

I have a Creative I/O USB2/1394 Firewire enclosure. I have installed
a Plextor 740A IDE DVD drive. When the DVD drive is in the desktop it
will test at the rated speed of the media. When I installed the drive
in the creative I/O external case and connect to either the USB2 or
the 1394 Firewire cable the media will not test faster than 2.4x no
matter what the rating of the media is.

According to the Plextor tech support the problem is with the bridge
between the IDE drive and my computers. I have tested with a notebook
running XP home and a desk top running XP Pro.

Have anyone had this problem? If you have and have solved please post
your solution to this message.

Thanks,

Do you have USB2? Or are you using Version 1.1?

http://en.wikipedia.org/wiki/USB#Transfer_speed

Version 1.1 will support 1.5 Megabytes/sec
Version 2.0 will support 60 Megabytes/sec

If your computer has only version 1.1 ports, you will transfer at the
slower rate.
And just because you have usb2 does not mean that it will support the
high speed transfer rate.

HOWEVER, given that this enclosure supports firewire, which has higher
bitrates, i suspect that the enclosure is your limiting factor. Which
is what Plextor told you. I would try a different brand enclosure.
