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 it fine.

What do you get if you run "parted -l /dev/mmcblk0"?

What does running "lsmod | egrep 'mmc|ricoh|sdhci'" produce?

It sounds like the reader may be in the wrong mode. But my experience is with the TI version of the built-in reader. It is also possible that the ricoh_mmc module is not being loaded.

Well, now that it WORKS here's some info...

Output of partd -l /dev/mmcblk0: Model: Unknown (unknown) Disk /dev/mmcblk0: 1024MB Sector size (logical/physical): 512B/512B Partition Table: msdos

Number Start End Size Type File system Flags 1 31.7kB 1024MB 1024MB primary fat16 boot

[root@localhost fedora]# /sbin/lsmod | egrep 'mmc|ricoh|sdhci' mmc_block 18688 2 ricoh_mmc 12544 0 sdhci 23564 0 mmc_core 52800 2 mmc_block,sdhci

I don't remember ricoh_mmc loading last time... The only thing I can think of that I did differently was boot up with the media in the slot... must have made it load the ricoh_mmc module.

Thanks,

Richard

Along those lines, is it possible to get the UUID of a disk from
windows?

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 labels.

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 tifm_core 10268 3 tifm_ms,tifm_sd,tifm_7xx1 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.
