Just to add to the fun; I have a card reader, which blinks a little light in 
response to sda, I never have got it to mount properly. It is the only mass 
storage USB device I have (though there is an emulated SCSI CD-writer which 
gets shoved up a device for it).

[root at dragon mnt]# mount /dev/sda ./cardreader/
/dev/sda: Input/output error
mount: you must specify the filesystem type

is as close as I get. I went through every supported filesystem, it won't play 
- this with a camera card and an iPAQ memory card, same effect. Tried mkfs on 
the camera card, it declined. I do however get a flashing light for my pains 
which is how I know it's /dev/sda. 

I note you're using sda1 & I'm not:
[root at dragon mnt]# mount /dev/sda1 ./cardreader/
mount: special device /dev/sda1 does not exist

/var/log/messages has this to say per attempt:
Sep  1 00:02:37 dragon kernel: sda : READ CAPACITY failed.
Sep  1 00:02:37 dragon kernel: sda : status = 1, message = 00, host = 0,

I just don't know enough about this to force it to work, and it isn't 
important enough to me to learn it! I've always assumed I'd have to reformat 
the iPAQ card (not an option) & the camera 2Mb cards are just too small?

It does get recognised at boot OK, and shown on the desktop by Mandrake's 
desktop thingy but it fails to read it if you click it!

Have to confess it works in M$... :(

Hope this comparison helps.
