Hello

I just recently purchased a Seagate Barracuda 200GB HDD and put it in a FW400 enclosure.

The Disk Utility is seeing 200GB but only state that I have 180GB available.

Where did the 20GB go??
Potential mac switcher but still researching

well some of it went to formating but I'm not sure if all 20gb was lost to that, it does seem a bit much. What type of enclosure is it? You say FW 400 but is it an old case b/c I hear some of the old cases do no support the same size drives as the newer cases.

This is part of the Common misunderstanding of how OS's and Hard Drives work.

Seagate looks at a harddrive and says 1000bytes is 1mb a operating systems looks at 1mb and says it is actually 1024bytes. So both systems are right. You haven't lost space just diffrent measuring standards depending on which side of the manufacturing isle you stand.


Edit: I just ran the numbers and my math maybe off or my numbers in the above post my be a bit off as well came out with about 188gigs though
Quicksilver 867, 700mhz iBook, 1st Gen iPod, iSight, Newton 2100, and a 128k Mac. All operating and used on a constant Basis
