Yesterday I bought a 250GB hard drive (IBM/Hitachi, just the drive, i.e. no external case), which I wanted to use to replace my external 160GB Maxtor drive as backup-drive. After I removed my 160GB drive from the case and installed the 260GB and attached it (firewire) to my 12" rev C Powerbook, it showed up as 128GB. (Not formated yet, but when I started up Disk Utilities.)

Now, I know that certain ATA controllers have a certain limit for the drive sizes that they can controll, but I would have imagined that if it can take a 160GB, but not larger, the 250GB would show up also as a 160GB.

I then installed the 250GB in my "very old, very first generation" G4 350Mhz, where it also only showed up as a 128GB drive.

Now, am I just very unlucky, that both controllers dont support larger drives and for some odd reasons the 250GB shows up as a 128GB in the external case, even though it supports drives as large as 160GB, and the old G4 doesnt go larger anyway,....
OR
is the drive broken?

any ideas and suggestions?

thanks
