I think I know the problem and the solution, but it's relatively  
difficult.

These 40GB drives were made at a time of transition of ATA standards.  
I believe the problem is that the HD itself has firmware that is older  
and perhaps purposefully set to an older standard so that it would  
work with older PCs. Also, some OEM PC manufacturers bought 40GB HDs  
in bulk and then crippled some in firmware to read as only 20GB. Then  
they'd offer an "upgrade" to 40 GB which was simply running a firmware  
program for about 1 minute and charging you a small fortune for this  
"upgrade". Anyone who never purchased the "upgrade" had a HD with  
crippled firmware that read half full. (Aside: this type "upgrade" is  
identical to what happens with vans and trucks, they place a large  
fuel tank in EVERY van & truck, and then put a "standard" filler  
nozzle that extends down halfway into the tank so that the tank will  
only fill halfway. Then they sell you an "oversize" tank by simply  
replacing the "standard" nozzle with a shorter "oversize" nozzle that  
allows the tank to completely fill. Both the HD upgrade and fuel tank  
upgrade are scams in my mind, and I guess you could toss QuickTime Pro  
into that genre also).

Maxtor made a flash program to reset the firmware on these HDs, but it  
is an old DOS program that runs on a PC only. There were several  
versions of this program. If you have a PC, I can email you a copy of  
the flash program off-list.
