I have a spare PC Card slot on my notebook computer and would like to put in a CF-card-to-PC-card adapter. Can anyone recommend one that is made for CF Type II?
Thanks!

| CF Type II, you mean the ones that are "thickerer?" |

I'm not sure if a CF II adapter will help, but I figured I'd ask anyway.
With my current PC Card adapter, it seems really slow...looking at the Robocopy stats for copying 1.2 Gb of photos:
Files: 98
Bytes: 1.176
Time: 0:22:29
Speed: 935772 Bytes/sec.
Speed: 53.545 MegaBytes/min.
At about 54 MB/min, that seems very, very slow. It took about 23 minutes to copy 1.2 Gb of data. That's unacceptable!
Here's are the results from when I copied the exact same set of files, but used a regular USB 2.0 CF card reader (one of those "all-in-one" readers)...
Files: 98
Bytes: 1.176
Time: 0:02:42
Speed: 7764279 Bytes/sec.
Speed: 444.275 MegaBytes/min.
The speed went up to a whopping 444 MB/min, and only took about 3 minutes.
So, I was wondering if a card was made for both CF Type I and II (if such a PC card exists), if that would help my speed (although the CF card itself is Type I).
Maybe it's something else? Has anyone experienced this?

What you need is a "cardbus" adapter. The normal CF-to-PCMCIA adapters have no electronics, they just provide interconnection. That gives a 16-bit data path. There are adapters that include a cardbus interface and can use the 32-bit data bus width. They are *much* faster. They cost about $80, as opposed to the $10-15 that a simple mechanical adapter costs. For transferring large amounts of files often, they are well worth the money. Look here for further information.
ETA: Also a UDMA version

Ah, that makes sense. Yes, I'm using an plain old adapter that's just acting as a passthrough.
Thanks for the info (and the links).
Is this one that should work? It's only US$39.

Yep, that one looks like it will work. It's the new version, so if your cards support UDMA, it could well be smokin' fast. In any case, it should be limited by your cards in the vast majority of cases.
ETA: B&H and Adorama both list it for $39 as well, so it looks like either prices have dropped, or I've got a poor memory! Probably the latter, you know they say the memory is the first second thing to go!
