I recently purchased an external Iomega USB 2.0 CD-RW 52x24x52 and it is not performing well. I am using the included HotBurn Pro software, version 2.3.3. I am using Memorex 48x CD-Rs, but if I try to copy faster than 12x, I get an unusable CD. My USB hub is 2.0, but it is integrated into the motherboard with six ports and I was wondering if adding another PCI USB 2.0 controller card for the Iomega would help. Any other suggestions as to what I could do to improve the performance? My machine is a Pentium IV at 1.8GHz, 256MB RAM, and I write to an image file on the hard drive before burning. Any type of help will be greatly appreciated.
Try the discs on a different burner to rule out the possibility that its the discs that are messing you up. You mention that anything faster than 12x results in a messed CD.... do you have DMA enabled?
Junk cd burning software and a memory hog as well m8. Be sure that you've installed USB 2.0 drivers and working properly. As Praetor mentioned, enable DMA and switch to a free burning software called burnatonce. burnatonce 0.99a http://www.burnatonce.com/downloads/ Shoey
Thanks for the help. I got to looking and it seems I have a conflict between the DMA controller and PCI bus, and also between the USB controller and several installed cards. I am trying to work out something with my computer manufacturer, but it will probably be awhile. I will try the BurnAtOnce program to see if it makes a difference.
How do you know m8? Are there "conflicts" with your USB controllers& installed cards? Right click My Computer>properties>Hardware tab folder>Device Manager. Do you see anything highlighted in "yellow"? If so post and maybe I can help. Be sure to click the + beside each device... Shoey
Nothing shows in Device Manager. However, in System information, I am seeing IRQ conflicts and other conflicts. Here is the info.: I/O Port 0x00000000-0x00000CF7 PCI bus I/O Port 0x00000000-0x00000CF7 Direct memory access controller IRQ 16 Intel(R) 82801DB/DBM USB Universal Host Controller - 24C2 IRQ 16 BCM V.90 56K Modem IRQ 18 Intel(R) 82801DB/DBM USB Universal Host Controller - 24C7 IRQ 18 Creative SB Live! series Memory Address 0xA0000-0xBFFFF PCI bus Memory Address 0xA0000-0xBFFFF RADEON 7000
