Hi again. After significant changing of settings etc, I seem to have found a potential solution. In bios under ide controllers etc there is an option to change the mode between "enhanced" (which apparently is best for xp) and "compatibility" (which is apparently best for 98, ME, 2000). When i change it to compatibility, i am able to transfer files between my drives. However, this mode only allows me to enable one ide controller (either primary OR secondary) along with SATA. Since i have one HDD connected to the primary IDE and 2 dvd drives connected to the secondary IDE, in addition to my 2 SATA drives, this means i would have to sacrifice a device in order for the HDD's to transfer properly.
Surely there must be a solution to this! The latest bios offers no fix, and i cant manage to hange any drive-specific settings or anything else to get it all to work.
