Locate devices:
```
camcontrol devlist
```
Output; in this case only:
```
<ST3500418AS CC35>                 at scbus3 target 0 lun 0 (pass0,ada0)
<ST500DM002-1BD142 KC45>           at scbus5 target 0 lun 0 (pass1,ada1)
<AHCI SGPIO Enclosure 1.00 0001>   at scbus9 target 0 lun 0 (ses0,pass2)
<Generic STORAGE DEVICE 1532>      at scbus10 target 0 lun 0 (da0,pass3)
<Generic STORAGE DEVICE 1532>      at scbus10 target 0 lun 1 (da1,pass4)
```
Where ada0 and ada1 are mechanical drives, da0 is a miniSD card in a USB enclosure da1

Or to print all partitions:
```
gpart show
```
Output (after formatting USB device):
```

List partitions on dev da0:
```
gpart show da0
```
Delete existing partitions:
```
gpart delete -i da0
```
Destroy label:
```
gpart destroy da0
```
Create new mbr spanning entire disk:
```
gpart create -s mbr da0
```
Create new fat32 partition spanning entire disk:
```
gpart add -t fat32 da0
```
Initialize fat32 file system:
```
newfs_msdos -F32 /dev/da0s1
```
Lets break something!

Don’t do any of this unless you are prepared to break it all, or better yet, you read the man pages and find out what they actually do, very useful tools however.

I’m just making notes from other notes, various resources on the net.
```
gpart destroy -F da0
```
Zero out the drive === !!!Don’t do this jazz regularly on any USB!!! The type of memory has a finite read/write number===
```
dd if=/dev/zero of=/dev/da0 bs=2m count=1
```
Format the drive
```
newfs_msdos -F32 /dev/da0s1
```

  If attempting to install FreeBSD on a disk which previously belongs to a ZFS, and you get this error: Before installing, select the option ‘shell’
  
  Once in the shell, remove geom protections by running:
  sysctl kern.geom.debugflags=0x10
  When your finished, type exit and return to the install / configure screen.

Which means geom is protecting the disk.

Running the following clears the protection:
sysctl kern.geom.debugflags=0x10
