CD writer and DVD/CD rom can't be shared in workgroup
I configured the CD writer and DVD/CD rom to be shared in workgroup on my
desktop running Windows XP Pro. All the users in workgroup can see the drives but not allow to access. I have given the write access to everyone Can someone advise the possible causes and fixes. Thanks, Ray

CD writer and DVD/CD rom can't be shared in workgroup
They don't need write access, they need read access.

Should I apply it to the pc with CD-ROM drive or the pc to access the CD-ROM drive. Thanks for your further advice. Ray "Kelly" wrote in message ...

Well, you're correct about not writing to the CD writer, but wrong about not
being able to supply data fast enough through a network - even the fastest IDE subsystem cannot perform as fast as even a 10mb network. -- Mike Matheny "Steve Winograd [MVP]" wrote in message news  In article , "Ray" wrote: I configured the CD writer and DVD/CD rom to be shared in workgroup on my desktop running Windows XP Pro.

Well, you're correct about not writing to the CD writer, but wrong about not being able to supply data fast enough through a network - even the fastest IDE subsystem cannot perform as fast as even a 10mb network. Are you sure about that, Mike? Here are the rated transfer speeds of some systems: Ultra ATA/33 IDE drive interface: 33 megabytes/second Ultra ATA/66 IDE drive interface 66 megabytes/second Ultra ATA/100 IDE drive interface 100 megabytes/second 10BaseT Ethernet: 10 megabits/second = 1.25 megabytes/second 100BaseTx (Fast) Ethernet 100 megabits/second = 12.5 megabytes/second As I interpret those numbers, the slowest IDE disk is almost three times faster than Fast Ethernet. Is that right? I've measured actual speeds for disk copies over a Fast Ethernet network, and the result is typically 50-70 megabits/second. That involves reading one computer's disk and writing the other computer's disk, and it's much faster than a 10 megabit/second network. -- Best Wishes, Steve Winograd, MS-MVP (Windows Networking) Please post any reply as a follow-up message in the news group for everyone to see.

CD writer and DVD/CD rom can't be shared in workgroup
It is important to note that most CD and DVD Writers can operate in DMA
Mode 2. This is 33 MegaBytes Per Second for the max throughput. The only way you are going to be able to burn a DVD at anthing higher than 8x over a network is if the network is capable of transfering that amount of data which would require a Gigabit Network. Also important to note is that most of these hardware components only operate at about 80% efficiency. This means with DMA Mode 2 (33 MB/s), you really only get around 25 MB/s. Burning 16x DVD's requires about 22 MB/s. One way to make sure that your DVD's and CD's are properly burned over the network would be to limit the speed of writing to handle the amount of data that can be transfered (and allow room for error as well). Here are my suggestions for writing to a CD over a network: For 10 MBit Networks: CD Burn speed of 4x (Though 8x may be possible, I wouldn't recommend it) DVD Burning will not work on a 10 MBit network For 100 MBit Networks: CD Burn speed of 52x (Full speed should be supported) DVD Burn speed of 8x (May lower to 4x on high traffic networks) ---- Nathan McNulty Steve Winograd [MVP] wrote: In article , "Mike Matheny" mikematheny@swbelldotnet wrote: When you share a CD or DVD writer over a network, it's shared as a read-only device, even if you've specified write access.
