Hi

A friend gave me a 2.5 inch HD and I wanted to put it in my Clamshell ibook but the attachment points on the sides keep it from fitting in the HD drive frame. Is there anything I can do?

Those black “attachment points” should be removable by unscrewing them. Does it look like it accepts an hex wrench?

Thanks I'll check... Yep they Unscrew. thank you..

Now the only question is will my Clamshell running 9.2.2 see a 120gig drive

That clamshell can use up to 128GB drive, but the boot partition needs to be less than 8GB, and needs to be the first partition on the drive. (?)
Am I mis-remembering something about that?

That's a peculiarity of old world ROM(ADB+Serial+floppy, no built in USB) when booting OS X from the built in IDE controller. OS 9 can be on a partition of any size, and OS X on New World ROM systems(built in USB) can do the same.

The absolute limit for OS9 was 190GB per volume, even on New World Macs. Apple's official line was 200GB but people found that 190GB was safer.


As said, the 128GB was a hardware limit of 48bit LBA built into the IDE controllers of Old World Macs. Those could be bypassed on desktops by using a PCI IDE controller card with a newer chip or a SATA controller or SCSI but only up to OS9's 190GB limit per volume on those drives. On a laptop, you just had to deal with what you got.
 
I fitted the drive and it works fine only it came up as 111 gig
That's normal. 120 gigabytes printed on the drive is to say 120,000,000,000 bytes which translates to 111.75870896 gibibytes (what OS X means when it says "GB") when divided by 1024×1024×1024.
