I use badblocks to test my 32GB class-10 microSD card that I use to boot my RPi. I already have a functioning file system on it, so I don’t want to scan it with the -w option (destructive read-write test).
I’m setting up udev to handle my external USB hard drive when it gets plugged in and removed (no mounting yet). So far, I’ve made two new rules in /etc/udev/rules.d/10-local.rules to log adding/removing the disk to a file:
Is it possible to export a block device such as a DVD or CDROM and make it so that it’s mountable on another computer as a block device?
Is there a way to take a disk img file that is broken up into parts and mount it as a single loop device?
I’m looking for a portable way to obtain parent block device name (e.g. /dev/sda) given the partition device name (e.g. /dev/sda1). I know I could just drop the last character, but that wouldn’t work in some cases:
