Welcome to the forums!
There is a hotfix by Microsoft to allow your system to "see" SDHC cards - applicable for XP (unsure of Vista, although technically it should recognize SDHC cards without added patches):
---> direct link to hotfix download: Update for Windows XP (KB934428)
This hotfix is included in SP3 for XP, so it's not a required download unless you're running XP-SP2 or earlier.
Hope this helps

Thanks for the input, you jogged me in the right direction. Somehow I expected this to be a hardware issue instead of an OS issue, but now that I think about it, it all makes sense.
After checking the Microsoft knowledgebase I found Vista is supported by hotfix 936825. I checked my update history and it was automatically loaded in Sepetmber of 07. Gotta love those automatic updates!
My intent is to use the SD card for ReadyBoost, however, I just plugged my 2Gig Datatravler into the USB slot and selected the ReadyBoost option from the pop up menu only to find that readyboost is already using another device on my computer. I do show a 513 Gig drive in the Storage Management Console, so I guess this is the built in flash that came with the T61p.
Glad I checked before I plunked down some hard earned cash for a speedy SD Card.

513GB is a lot. You mean 513MB perhaps. Do you have the Intel Turbo Memory card (1GB) installed on your system? That could be it. If that is the case, Vista won't allow you to use another device for the "memory boost" feature.
Either way, keep in mind that Microsoft drastically reduced the number of compatible "memory boost" flash drives in the latest SP1 for Vista. There are numerous posts about this new SP1 "feature" all over the internet. This means that not all those flash drive units that worked well in vanilla Vista will now work if you install SP1 for Vista.
Just a heads up.

You are quite right...I was typing so many Megs and Gigs I got them backward! I do have the turbo memory feature that was offered, although it was advertised as "Intel Turbo Memory 1 GB" and it shows up as 513 Mb (instead of 512 for some reason). One of the articles I read earlier today mentioned something about compression which would make up the difference. Everything seems to work pretty well as far as the hardware goes, so I'm not going to complain over that small amount of memory.
This is the first time I've heard the term "vanilla Vista". I seem to be getting along pretty well with the program so far but I probably don't delve as deeply as some who don't like it.
Thanks again for your info!

Hi, I tried the Microsoft upgrade on my T61P but am still not able to use SDHC cards using the 4 -in1 reader. I hope this problem can be solved as I was planning to use the 16Gb SDHC card from my Canon HF10 videocamera in combination with the 4-1 reader (no cables etc.). NB: the SDHC cards work fine through a USB stick converter.
I get the impression from the ricoh site that the hardware is not compatible, there seems to be a new chip available that is able to use SDHC. The ricoh driver does not affect the SD/SDHC performance.
Is anybody more successful using SDHC in an T61?

I encountered the same problem in a slightly different way - with every official SDHC update installed, I could only see 4Gb cards, not the shiny new PhotoFast 16Gb card that I just got. I wanted to ensure that the 4-in-1 card reader in my T61 was the running the latest driver for its internal Ricoh hardware.
I had no luck, so started trawling through forums that dealt with competitor (starts with D...) support and found articles about the same Ricoh 4-in-1 card readers. They commented that the chipset was common to a lot of Lenovo notebooks as well, although the T61 wasn't listed (it was a slightly old article).
The article stated that the packaged "official" reader updates only include drivers from as old as 2001 - well before SDHC was a mature standard! I thought I'd take a gamble and see if the Ricoh-specific drivers would work, and lo-and-behold, they do!
How I did it:
1) I copied C:\Windows\system32\drivers\risdtpsk.sys to somewhere safe (you can always boot in to Safe Mode)
2) I downloaded this driver, specific to the SD reader part of the Ricoh chipset. Unzip it somewhere you remember
3) Clicked Start -> Settings -> Control Panel -> System -> Hardware -> Device Manager -> IDE ATA/ATAPI Controllers and double clicked "Ricoh SD Host Controller"
4) Change to the Driver tab and select "Update drvier..."
5) In the Hardware Update Wizard, say No to connecting to the Internet (if presented with an opportunity to do so)
6) Select "Install from a list or specific location (Advanced)"
7) Select "Don't search. I will choose the driver to install."
8) Click "Have Disk..."
9) Click "Browse..." and locate the unzipped files from step 2. Select risdtpsk.sys
10) Select "Ricoh SD Host Controller"
The system will then update and ask to reboot. Save all work and say yes.
After that, my 4-in-1 recognised a variety of SDHC cards (4Gb, 8Gb) as well as the 16Gb Dual channel Class 6 SDHC I wanted.
Hope this helps!

I have a question for you: Does your Ricoh 4 in 1 recognize and can utilize Ready Boost? I have a few different cards that will ready boost on an external card reader, but when I insert them into the ricoh 4 in 1 it doesen't give me the option to Ready boost, but only to use as a normal card?? Their is 1 exception: I have an 8 Gig sony pro duo card that gives me the option, but says that i doesn't have the speed requirements to "Ready Boost". My Transcent 4gig card that I use on the external card doesn't even give the option to "Ready Boost" when I insert it into the Ricoh 4 in 1 reader. I can ready boost from the 8gig Sony Pro Duo only after repeatedly saying test again,test again ect.ect. But after doing so, it is quite obvious on my machine that it doesn't like it, where as in the external it is fine and works as normal! Any Ideas! I have been trying to find an answer to this issue for quite some time! Thanks for any help.

I'm afraid to say I have no idea. I downgraded to Windows XP (work security and infrastructure requirement) so I haven't been able to test that. I can attempt it on one of my colleague's machines and will let you know....

Ok, Thanks a bunch Kalon, I have been trying for about 6 months to find a solution to this problem. I have the latest drivers and I have also read that the 4 in 1 card readers thruput is very slow. I don't know if it is a driver problem or what??
