/dev/sda1 doesn't exist

Hello,

Whenever I try to mount my flash drive I use this command: 

#mount /dev/sda1 /mnt/usb

For some reason, it says now that /dev/sda1 doesn't exist.
I think my flash drive itself is dead but it's not inserted when the computer starts so I don't know why the device isn't in /dev.
I'm currently at school so I can't give the exact error. Tell me if you need the output of any command.

Re: /dev/sda1 doesn't exist

I do have other things in the usb ports. They're a brother printer and a wireless mouse piece. Here is the output of dmesg:

Re: /dev/sda1 doesn't exist

I assume the device you are looking is connected.... if it is then its not showing up then it may be faulty ... you use a hub at all ... try connecting directly to pc

Re: /dev/sda1 doesn't exist

Yea its directly connected to the pc. I plugged it in a Windows computer and nothing happened so I assuming that the drive itself is faulty. Thanks for your help.
