Done, checked out fine. About 50MB/s.

Checked. There are two IDE slots on my mobo. One hooks up both my HDs and the other is for the optical alone.

Ok, how do i check if that's enabled or not? ( my mobo is a VIA btw )

Kinda lost me there. How do i check the DMA (edit, ok, i checked, it's enabled as multi-word(?) DMA mode 2) and what 4 in 1 drivers are you talking about?

Nah, i always keep my HDs perfectly defragged. I use the slower one for downloads and the faster one for storage and burning. The

Yeah, if i can get this speed-lock issue in check the max i'll get is 4x anyways. My DVDR was 8x, probably gonna get a 16x for the exchange, but I can't seem to find any media around here over 4x. :-\


Gives us a kiss precious.
