how to find the right /dev file?
I keep hitting this problem, because I have no method dealing with it.
I have a USB memory key, which on my own PC comes up as /dev/sda1. I go another PC, load Knoppix, but sda1 is called an invalid block device. OK, I think, just try out the other "usual suspects", /dev/sda, /dev/sdb, etc. No luck. dmesg tells me a USB mass storage device has been found, but no clues as to which file in /dev. Similarly lsmod tells me, it's there but nothng else. And there are so many files to choose from in /dev! Which one could it be? IS there any sort of autmated method of sifting through them and finding which one? Or has it always got to be a manual trial and error thing? |
I used to find this by doing
fdisk -l /dev/sd* if it finds a device with a partition on it, it will list it. I have no clue whether that's the "correct" way of finding out which device to use, but it still hasn't failed me so far :) |
Hey that's pretty cool.
I think most people just hope that conventions are followed and do it by trial and error. May be there is no correct way. Yours quickens up things a good bit, thanks! Good one! |
