While in Ottawa for BSDCan 2015 and PGCon 2015, I obtained a 4TB external USB HDD. It now contains copies of the videos back to 2012 for BSDCan and PGCon. This is for backup. All these videos exist elsewhere (e.g. Youtube) and I have these just for backup.

NOTE: the videos for BSDCan 2015 and PGCon 2015 will be online as soon as they are available. There is no ETA.

Here’s what it shows up as when plugged into a FreeBSD 10.1-RELEASE server:

Here is me trying to get it mounted:

$ sudo mount -t msdos /dev/da0p2 /mnt
mount: Using "-t msdosfs", since "-t msdos" is deprecated.
mount_msdosfs: /dev/da0p2: Disk too big, try '-o large' mount option: Invalid argument

$ sudo mount -t msdosfs -o large /dev/da0p2 /mnt

Good. Now let’s go read-only, like I should have before:

$ umount /mnt
umount: unmount of /mnt failed: Operation not permitted

$ sudo umount /mnt

$ sudo mount -t msdosfs -o large -o read-only /dev/da0p2 /mnt
mount_msdosfs: /dev/da0p2: mount option  is unknown: Invalid argument

$ sudo mount -t msdosfs -o large -o ro /dev/da0p2 /mnt
$

Ahh good.

How much do I have to copy over:

$ df -h /mnt
Filesystem    Size    Used   Avail Capacity  Mounted on
/dev/da0p2    1.6T    275G    1.4T    16%    /mnt

About 1.6TB. That should work…
