/dev/sdxx disappear?

**DoctorDan** · 10-30-2005

I upgraded from 2.4.27 to 2.6.14 kernel yesterday from kernel source (meaning i went from devfs to udev if that has anything to do with this). after this I now have no sda, sdb, etc. i only have these ptyxx ttyxx things (x is a letter or number) in /dev instead. i want my sdxx's back!. Thoughts? I'm having a lot of trouble on google trying to figure this out.

i read that page and could not find much to help me. i'm still pretty new to linux, so i may not be finding what you intended for me to.

I'm assuming that you have hotplug and udev started?

**DoctorDan** · 10-30-2005

yes

**lakerdonald** · 10-30-2005

What is the exact device that you are trying to use?

**DoctorDan** · 10-31-2005

sda1 and sdb1

they're just gone from my /dev/

I meant the physical devices.

usb flash drive and ipod mini, but either way i want my sdxx's back

My experience with Debian is that device files don't appear until the device is plugged in. Everything is done automatically.

Have you plugged the devices in and still have the same problem? If yes, run "/dev/MAKEDEV sda" or "/dev/MAKEDEV sdb".

Type "man MAKEDEV" for info on how it works. Like I said though, my experience with Debian has been that these block files just appear out of no where when the kernel detects them.
