Ubuntu 6.10: External DVD RW will work on desktop, but SLOW on laptop


Hello:

I have an interesting problem that I am unable to solve. I have two computers, one is an HP Desktop and the other is a Dell Inspiron 2650, both of which are running Ubuntu Edgy. The Inspiron is running 512MB of ram, 60 GB Hard Drive, and 1.6 P4. I recently purchased an internal DVD Recorder and then bought an external USB 2.0 Case for it. (so I could use it on the laptop).

When I connect the DVD Drive to the HP, GnomeBaker or K3b will write to it with no problems at all. (Approximately 5 min for 4 gig). When I hook it up to the laptop though, GnomeBaker and K3b both write to it at speeds approximately 0.6X. It also reads from Decrypter in Wine at 0.7X .

I have done my research before posting, and tried to enable DMA on the laptop. When I enter this command: hdparm -d1 /dev/sr0 I get the following output:

setting using_dma to 1 (on)
HDIO_SET_DMA failed: Function not implemented

The reason why I used sr0 is because that seems to be where it is mounting my USB drive. I am scratching my head here, especially because it will work fine on my HP, just no the Dell. I have also checked to make sure that the Dell is reconizing it as a USB 2.0 Device, which it is. The enclosure is a NexStar 2 and the Drive is a : Optiarc DVD RW AD-7170A .

Any advice or information that someone could provide would be greatly appreciated. I have been scratching my head on this for awhile now, and am very anxious to get this resolved. Thanks in advance!
