    2.5" HD + 40 wire cable = Ultra ATA/33?

    Before winter starts, I plan on replacing my CarPC's 3.5" 40 gig HD with one of Seagate's "Extreme Environment" series 2.5" HDs since I know for a fact that my current HD can't take the cold very well at all.

    These HDs have an Ultra ATA/100 interface and run at 5400 RPM. My motherboard is a VIA SP13k, so the IDE interfaces are capable of Ultra ATA/133. The problem is that the only cable that I have that converts between 3.5" 40 pin to 2.5" 44 pin is a 40 conductor cable, similar to this:

    If I remember correctly, if you use a 40 (rather than 80) conductor cable on devices that are capable of ATA/66 or higher, they will drop down to ATA/33 speeds. Won't this greatly increase my times coming out of hibernation?

    If that is the case, will this adapter,

    when used in conjunction with an 80 conductor ribbon cable allow the new 2.5" HD to run at ATA/100 speeds?

    Short answer : Yes. Have a look in your bios too, just to make sure things are as expected.

    Is that "Yes" in response to my first question (I'll have greatly increased times out of hibernation), or to my second question (that particular adapter will allow the new hard drive to operate at full speed), or possibly to both my questions?

    Thanks for the response. I just need a slight clarification.

    Nope, I anwered your ATA100 concern. Of course, if the puter can acces Hdd faster, any action involving hdd should be done faster.
