Full height 3.5" drives are 1-5/8" tall, which just happens to be 1/2  
of the height of a full-height 5.25" drive.

1-5/8" is 1.625".

One half of 1-5/8" is 0.8125"

For marketing reasons, manufacturers try to make 3.5" drives a  
maximum of 1" high, except for the older SCSI models, for which  
1-5/8" applies.

The SE, SE/FDHD and SE/30 drive carrier was designed for 1" drives.  
It cannot accommodate 1-5/8" drives.
