first of all my NEC 2500A was burning 4x Riteks @ 2.4 speed.
and should have been doing 4x

so i started looking about and found out that my DMA on this drive reverted to MultiWord DMA 2

instead of ULTRA DMA 2

im wondering why this happened ???

anyone know why ? :eek:

Could be

a) bad IDE cable

b) DMA disabled

c) non DMA capable device on same channel e.g. Zip drive

The Multiword DMA might explain the 2.4x burn. What is the media code for the discs?
