im using Slackware 10.1 on kernel 2.6.12.3

whenever i plug in pendrive

it detects it as scsi1 device

but i have no node as sda or sdb made on the OS

so i run this comman

# mknod /dev/sda c 8 0
# chmod 777 /dev/sda
# mount /dev/sda /mnt/pendrive
sda is not a block device

im getting the above error
how do i mount the pen drive

What do you see from dmesg right after you plug it in? It may not be a simple /dev/sdaX (my camera isn't, for example.)

dmesg i wrote above is detecting it as scsi device....

Shouldn't you be mounting sda1 and not sda? In order for you to access a drive to read or write data there needs to be at least one partition.

sda1 is also giving me the same error message

Check to see if the device is recognized as /dev/uba when you plug it in. I had this happen when I upgraded to the 2.6 kernal from the Slackware 10.1 cd. It would mount for me but would not let me copy to or from the drive though. I am sure it is just an option in the kernel but am not sure which one. Upgrading again to the kernel packages in the current tree under testing solved the problem for me. If you don't want to try upgradin the kernel as an option this ealy in trouble shooting and it does show up as /dev/uba then try to see if you have the sd_mod module as in this earlier thread.
