The SD Card slot (Secure Digital) is found on select ThinkPads and Docking stations.
In addition to SD Cards, SD Card slots can also accept the older MMC (MultiMedia Card).
PCI-based SD Card slot
This implementation is called "SD Card with IO support", and supports in addition to regular SD memory cards also special SDIO cards (e.g. Bluetooth, WiFi, etc).
Linux support
You can read/write large SDHC cards since Linux kernel version 2.6.22, this has been tested on X41 Tablet, X41 and X40 with 16 GB SDHC (FAT32), 4 GB (non-HC, FAT32) and 2 GB (non-HC, FAT16) cards. However there have been some old reports that you can't, delete, create, resize or format partitions, there seems to be no problems with this on 2.6.24. These problem will not exist if you use an USB connected SDHC card reader instead of the internal one, so you can always use the cards.
The driver where coded by the SDHCi project supporting these and other SD controller chips, making them work with SDHC cards as well. The driver has been reported to work on ThinkPad X40, X41, Z60m, Z60t, X60 and X61 models, and has been available in mainline kernel since 2.6.17-rc1. See also "How to get the internal SD-CARD working".
lspci reports it as a Ricoh device with PCI ID 1180:0822 (X Series, Z60m, Z60t), or 1180:0841 (Z Series).
Windows support
The Microsoft hotfix 934428 is available here [1] it adds SDHC (SD High Capacity) support to Windows XP SP2 systems.
Models featuring this Technology
- ThinkPad X40, X41, X41 Tablet
- ThinkPad X60, X60s, X60 Tablet, X61, X61s, X61 Tablet
- ThinkPad Z60m, Z60t
USB based SD Card slot
This implementation only supports SD Memory cards.
Linux support
Should be supported by the Linux USB Storage drivers (usb-storage).
