Ok so the USB disk device name changed from sde1 to sdb1. Is that possible without a reboot ? As far as I know the disk was plugged in all the time and I’m sure there was no reboot.
Is it possible to make permanent udev rules for such a disk ? I believe it is but could someone point me to some simple howto ?
Thanks for help. I have discovered that the name was changed because the disk has external power supply and there was a power supply outage. That’s why the name was changed.
