I am having trouble getting Fedora 9 (x86_64 live cd) to read my SD
card using a built-in Ricoh MMC reader on an HP 8510 laptop (Core 2
Duo). I get mmcblk0 and mmcblk0p1 in /dev but any attempt to read the
card fails. I see an icon in Nautilus but after opening it and a brief
pause I get an error "Can't read superblock". Also, any attempt to
inspect the device in parted or fdisk also fail. They both complain
about lables but I'm not sure if they are talking about filesystem
labels or volume lables. I can't see why the latter would cause an
issue. I tried the mklabel command in parted setting it to msdos but
it couldn't complete... I'm in Windows XP right now and it's reading
Along those lines, is it possible to get the UUID of a disk from
It sounds like it is trying to mount the card as a ext2 file system.
I am not sure why that is. As far as the labels, you need to copy
the exact message - I don't think it is talking about file system
Dumb question - when you are trying to use fdisk, are you using
mmcblk0 or mmcblk0p1? You should be using mmcblk0.
I have similar problem on HPnx500 with a built-in sd card reader
After insert sd card, dmesg only show
tifm_core: MMC/SD card detected in socket 0:0
nothing happening in /dev
here is output of lsmod|egrep 'sd|timf'
sdhci 17540 0
tifm_sd 12552 0
mmc_core 40604 2 sdhci,tifm_sd

sd_mod 26008 5
scsi_mod 122876 4 usb_storage,sg,libata,sd_mod
how to get this fixed?
You have a different chip set from the OP - you have the TI chip
set, and he has the Ricoh chip set. They use different drivers. I am
not sure why you are having problems with the TI drivers - they have
been working correctly in my Toshiba laptop. I forget the first
kernel that they started working without tweaking the registers
before loading the modules, but I think it was in FC6. You should
file a bug report because it may be something to your specific setup
and it will probably not be fixed otherwise - the developers do not
know there is a problem if the people it is not working for do not
file a bug report.
