 Coming from a Linux background, creating drives on OpenBSD is a little weird.

 Creating a FAT32 drive in OpenBSD is of course doable.

 This last command did't produce any output, it just quit after thirty seconds or so.
 From my experience, `newfs` can take time, so I wasn't concerned about the time it took, but there was a problem.
-After running `newfs` and running `disklabel -h sd3`, I saw that the `i` partition was gone.
+After running `newfs` and running `disklabel -h sd3`, I saw that the `i` partition was gone and of course as a result I was unable to mount or do anything with the disk.
+
+At that point, I tried a few things, including formatting the partition using `newfs_ext2fs`, but that seemed to hang completely without doing anything at all.
+
+Stuck.
+
+It was then that I decided to look at a FAT 32 drive I was already using for my ~/Music folder, managed using `beets`.
+I couldn't remember whether I created this drive in Linux or OpenBSD but I knew it was a FAT32 drive, mounted using `mount_msdos`.
+
+The interesting and surprising thing was that `fdisk sd2` revealed that it did *not* have a `A6` OpenBSD parition on it. Nothing.
+`disklabel -h sd2` revealed an `i` partition of type `MSDOS` which is what I would have expected.
+How was this?
+Does a USB drive not require a MBR? Surely it needs a partition table, albeit the "boot" element of Master Boot Record is probably notable.
+
+And here is demonstrated my lack of knowledge about operating systems, particularly the boot process. No shame in that - no one is really supposed to know this stuff that doesn't have a computer science degree or is a sysadmin of sorts.
+
+So I decided I need to try and replicate the situation I could see with my Music drive.
+To do this, I used `dd if=/dev/zero of=/dev/sd3 bs=1M`, but I didn't need it all doing so I quit after ten minutes (probably just needed to zero out the beginning of the drive with `count=1` but, as I said, what do I know?).
+
+`fdisk sd3` proved that the `A6` partition was gone.
+
+I repeated the steps, creating a new `i` parition and formatted the drive.
+This time it worked.
+
+I could mount the drive on OpenBSD and on Linux, but without a partition number, which is very very weird to me: `mount /dev/sde`.
+I have no idea if what I am doing breaks some universal law or it entirely congruent with one that I have no knowledge of.
+Clearly the latter.
+
+Either way, I got my drive.

+Lovely bright day today.
+
+A *great* day to release a [hastily-written blog post](../blog/trouble_with_usb_drives_in_openbsd) on formatting USB sticks.
