it is a 16GB class 10 Transcend, but the eeepc uses a usb card reader inside of it - no mmc I think.
Actually, the first thing I tried to do with it was to format to ext2, and then the formating proccess frozed in the middle of it.. I've tried to load it in a windows pc after but couldn't read, and when I tried to format, everything frozed - but it was a public computer, so I don't know if it ever had a working card reader. I've booted ubuntu in the eeepc now, and the card is shown in /dev/sdc1, but I can't edit it using disk utility - it gives me error calling fsync(2), on:/dev/sdc: input/output error. But on ubuntu I don't see no dmesg error msgs like the ones I see on gentoo just by plugin it on the port. Is there any disk error checking utility in gentoo or ubuntu? Érico V.
