Plextor 716SA problem

AMD 64 3200+ Winchester
eVGA Geforce 6800GT
WD Raptor 74GB HDD
Maxtor Maxline 10 300GB HDD
Crucial Ballistix PC3200 1GB

Ok problem, last night when I first installed Windows some how some way while transferring a 2.5GB file off of a DVD to my Raptor HDD it was blazing fast. Today I had to format and re-install Windows again. This time copying the same files from the DVD yielded different results. It was extremely slow. It said it would take around 11 minutes to complete everything.

Any ideas on what might be causing this slow down?

Yes, DMA is probably not enabled anymore. Have a look here:
My Plextor drive is burning and/or reading very slowly.

Good luck :wink:
