[Soap Box Mode ON:]

5.25" refers to the width, not the height..
But one Full height would take up two 5.25"
bay Slots..

I own two 300 Meg Seagate MFM Full Height Hdd's
that took up 4 Bay slot's on a Full Height Tower Case
and they sucked up so much Amperage on Boot-up
that they Over-loaded the 300 watt power supply,
and the Computer would Crash on boot-up..

The Trick to Using Booth HDD's in the same Computer
was a Jumper Switch on the Drives,
that Let you Delay the Boot sequince on the Second
HDD, until the First Hdd was Booted and Running..
Once that Big Drive was Booted, It drew only 5 amps
or so and that allowed enough Amperage for the second
Hdd to Bootup.. (Now you know a little more about
how much fun we FidoNet Sysop's had durring the early
years)


I own several dozen full Height Drives,
Mostly MFM formated HDD's (10mb,20mb,40mb,80mb,120mb,300mb)

Half-height IDE's were a God-send to Sysop's
