W700 internal Ricoh card reader under XP x64

2009-10-19, 21:23 PM

I'm very pleased that lenovo finally decided to release Windows XP x64 drivers. However the drivers for the internal Ricoh SD card reader don't work on my W700 (2757CTO). When I insert a SD card into to the reader the LED goes on but no drive is displayed in "My Computer" or "Computer Management\Disk Management". The driver installation went smoothly and resulted in addition of three Ricoh controllers (Memory Stick, SD/MMC, xD-Picture Card) to the device manager. The "Add or Remove Programs" panel lists a "RICOH R5U8xx Media Driver ver.3.58.01" as it's supposed to be. I tested this on a clean XP x64 in addition and the same SD card works fine in two other card readers (USB and ExpressCard). I also have Vista x64 and 7 x64 on the same machine and the reader works properly under the two OS. Any suggestions?

 

Thanks

I found a solution myself. The problem isn't caused by the Ricoh/Lenovo drivers but by the Microsoft SD Bus driver, which doesn't support SDHC. There is a hotfix for XP x86 provided by MS (KB934428). For x64 however there's only an unofficial source available:

The new x64 driver is from Microsoft as well and I don't know why they don't offer it officially on their own site. At least after installing this hotfix my SD card reader works properly.
