Is there a way to switch a internal card slot from /dev/mmcblk0** to /dev/sd** ? I'm backing up (via rsync) an ebook directory (1.9gb) to sd card and get massive i/o errors, card turning read-only,etc. This is via a built-in slot on a toshiba laptop. When I use a card reader, the card attaches to /dev/sdd1 and all is fine.

This is a new Sid install. The laptop's card slot worked fine under Ubuntu 9.04 and still works if the amounts of data are small. All I can figure is that the mmcblk device dies under a heavy load...

Thanks!

Never mind on this one. modprobe sdhci seems to fix the problem I has having with the toshiba sdcard reader.
