Probably the reason that you hear so little is that you provide so
little information. Most of us are not clairvoyant.

Why would you force an unmount?

For starters, how big is ar0s1g? If the offset is in bytes, it is around
270 GB, which is not that unusual in this day and age.

What does 'df' say?

Did you notice any file corruption in the filesystem on ar0s1g?

Unmount the filesystem and run fsck(8) on it. Does it report any errors?

Did you manage to create a partition larger than the disk is (using
newfs's -s switch)? In that case it could be that you're trying to write
past the end of the device.
