I'm helping out a friend with his computer. The problem is that it won't copy from the CD-ROM drive (e:) to the CD-RW drive (f:) directly. I can use the E: drive to rip a CD without problems at about 7x-8x speed which is about what I get with my 40x CD-ROM on another system. I can then write that data to a CD-R with the F: drive at 8x speed (1200 kb/sec) without problems. But if I try to copy directly from E: to F: (simultaneously) I consistently get a buffer underflow error after 5-10 minutes and the copy is automatically aborted. When the reader and writer obviously work fine independantly, I have a hard time figuring out a possible cause for them to fail when operating simultaneously.
The CD-ROM (E:) is on the same IDE port as the hard drive (C:) - they are both on IDE1, the hard drive is the master and the CD-ROM is the slave. The CD-RW is the only thing using the secondary IDE port (and is the master on that line).
Other stats for the machine: 333MHz Celeron, 64MB SDRAM, ~3 GB hard drive, 2MB video SGRAM. I don't know for sure, but I suspect that it has a 100MHz bus. I think the CD-ROM (E:) is a Goldstar 40x, and the CD-RW (F:) is an HP 32x read / 8x write / 4x rewrite.
Any ideas on why they won't work together or how to get them to work together would be much appreciated!
