Safely remove hardware, also partitioning new HDD?

[Kenny]

1.Why does a newly added internal SATA HDD appear in this but not a wireless
USB adapter?

2.New SATA internal drive, wanted it split into 2 roughly equal partitions.
Created one logical partition but when I went to create the second the only
option I had was Primary partition.
Why is this and does it matter?

When you created the Extended partition did you specify the full capacity of
the drive prior to creating the Logical drive?

Because SATA can be HOT SWAPPED, but the wireless won't have data pending.

You may have only ONE extended partition which is where the Logical
partition was placed, you may have up to 4 Primary partitions or 3
Primary and 1 extended partitions.
