Having issues unmounting partition for debian install
Clash Royale CLAN TAG#URR8PPP
I have a 50gb partition set up on my mac for installing debian, MS-DOS (FAT) format. I blessed it and am now unmounting it in order to copy the img file over. I'm using:$ diskutil unmountDisk /dev/disk0s5 to unmount and am planning to then use: $ sudo dd if=debian7.8.0-amd64-CD-1.img of=/dev/disk0s5 bs=1m to copy the img file to the partition.
The problem is every time I try to execute the unmount on Term, it gives me Unmount of disk0 failed: at least one volume could not be unmounted. I've verified this is the right disk using diskutil list. Any ideas what is wrong?

At least one process (or the kernel itself with another mount) is using this volume. That may be an open file or just the current working directory.
If /dev/disk0s5 is mounted to /mnt/tmp then run
fuser -vm /mnt/tmp
to find out which processes block the unmounting.
You find the right mountpoint (under Linux) by searching /proc/mounts for the block device:
grep ^/dev/disk0s5 /proc/mounts
Or you may use the command mount.
But I must admit that I ignored the point that Linux doesn't call it's drives /dev/disk0s5 thus I guess you described what you did under MacOS. That would explain the different fuser behaviour.

I have a couple questions regarding this answer. First off, how can I check where/dev/disk0s5is mounted? Secondly, I tried usingfuser -vm /mnt/tmp, and I gotUnknown option: k Unknown option: m fuser: [-cfu] file ... -c file is treated as mount point -f the report is only for the named files -u print username of pid in parenthesis. Suggestions?
