Help! I tried mounting my Nikon D70 camera on my mandrakelinux 10:
> # mount /dev/sda1 /mnt/camera

but this is what I got:
> /dev/sda1: Input/output error
> mount: /dev/sda1: can't read superblock

I tried checking in USBView and found that linux has detected my hardware and recognized that it is a D70.

can someone please help me?

I had this same problem with kernel 2.6.5-1. The problem seems to be with the kernel.
I recompiled the kernel without the EFI partition support and things are working fine now.
EFI partition support is required only if you are on IA64 machine. I dont know why its enabled by default.

thanks for your reply.

If its not too much on your part, can you please tell me how to recompile without the EFI partition support.

Hmm giving a full explanation would be out of question. you can find lots and lots of help on this on the web.
Simplest I can tell you is
download the kernel sources (or install it from the rpm)
the sources will be kept in /usr/src/linux.. directory for ex mine is /usr/src/linux-2.6.5-1.358
go there
type make xconfig
you will be presented with a gui asking about various options. (If you are not sure which one to take and which one to avoid just blindly accept what ever is default)
Save the configuration
you will find a .config file. edit this file and comment out the CONFIG_EFI_PARTITION. (Instead of this step you could als o disable the same from the gui in the earlier step just deselect Filesystems->patitiontypes->GUID EFI partitions)
run the following commands
make
make modules_install install
reboot to this kernel (grub will show an entry like title Fedora Core (2.6.5-1.358custom)
now try mounting your camera .

ok I'll try that. hope it works. thanks for your help zeropash
