Hello,

I have an external HD which I use for backup. It is connected over USB
2.0 and usually but not always (only when it is the first
USB-mass-storage device) shows up as /dev/sda. Now I have had some
problems as it did not show up in usbview anymore and I could also not
mount it. After some time I realized that /dev/sda1 did not exist
anymore. "ls /dev/sda1" gives "No such file or directory". I have been
playing around with hotplug lately and I sometimes mix up mv and rm. I
think it is possible that I deleted it. How can I create a new /dev/sda1?

Happy Hacking,

1. ls /dev/sda?
On my old compaq server, I get...
brw-rw----    1 root     disk       8,   1 Dec 24 18:19 /dev/sda1
brw-rw----    1 root     disk       8,   2 Dec 24 18:19 /dev/sda2
brw-rw----    1 root     disk       8,   3 Dec 24 18:19 /dev/sda3
brw-rw----    1 root     disk       8,   4 Dec 24 18:19 /dev/sda4

I hope that you'll get a few sda's back so you can get the correct major device number.

2. mknod /dev/sda1 b 8 1
That's using the values above.

Alternatively, there's usually a script called /dev/MAKEDEV or similar, that'll do it for you.


Alternatively, I think it's usually run on reboot.


hth,
