Posted by mkenyon2 on Aug. 20 2008,20:10I've got a USB memory card reader, and an SD card (128Mb). DSL is installed on the hard drive.
When I plug in the reader, I get in dmesg:
USB Mass Storage device found at 4
sda: Unit Not Ready, sense:
sda : READ CAPACITY failed
Then a bunch of I/O errors....
I/O error: dev 08:00, sector 0
I/O error: dev 08:00, sector 16
I/O error: dev 08:00, sector 8
I/O error: dev 08:00, sector 24
Posted by ^thehatsrule^ on Aug. 20 2008,20:23Can you mount it anyways?
To make it compatible, you may have to reset the partition, formatting, etc.
Posted by mkenyon2 on Aug. 20 2008,20:31Doing a
mount /dev/sda /mnt/sda
mount: relocation error: mount: undefined symbol: blkid_known_fstype
I've also tried with -t vfat and -t msdos
On my WinXP box, it's a FAT format.
Posted by ^thehatsrule^ on Aug. 20 2008,21:40Yea, you might have to change it as in my previous post.
I'm guessing that using a newer/patched kernel might allow you to mount it, but it's probably more work... and making it compatible will probably be the better way.
Posted by mkenyon2 on Aug. 20 2008,22:36You mean change the format? To what? NTFS? It was Fat32, and that didn't work. I'm thinking that the memory card reader might not work with linux, or maybe something isn't loaded correctly w/ modprobe.
Posted by ^thehatsrule^ on Aug. 20 2008,22:46There are some problems the way some devices are factory formatted iirc. You can search around for others' experiences if you want.
Posted by mkenyon2 on Aug. 21 2008,19:37I see the device come up as sdb in dmesg, but I can't seem to fdisk it.
sudo fdisk /dev/sdb
Unable to read /dev/sdb
Posted by ^thehatsrule^ on Aug. 22 2008,03:57Wasn't it sda in your first post?
Posted by mkenyon2 on Aug. 22 2008,13:25If I boot, and plug in my thumb drive, it comes up as sda, then if I switch to the card reader, it becomes sdb.
