 The firmware hack has the advantage of being based in the hardware's

 though as I Didn't have classic when I started using this method.


The LBA48 property is lost ONLY IF the reset-nvram O.F. command is  
issued.

If NVRAM is not reset, then the property remains active.

The LBA48 property is automatically included in all QS 2002 and later  
G4s.



 The Hi Cap driver costs money. and is an actual driver inside the OS.
 This would have to be reinstalled any time you reinstall the OS. It
 doesn't support OS 9. but does support 10.2 and up.

It isn't needed on OS 9, per se. However, a special initializer is  
needed for OS 9, which is provided by HDST.

It IS needed on OS X, and it works up to 10.4.11, but it doesn't work  
on 10.5, which is why I abandoned it and went back to LBA48.

LBA48 works on all later G4s (AGP and later, I believe, and certainly  
on all Gigabit through QS 2001).

 Hello, Y'all,

 I have a 450 Sawtooth AGP with 2 HDs, a 5400 60 gb and a 7200 10  
 gb. Memory is one gig. When I upgraded from OS 9.2.2, I went up to  
 a very stable OS 10.2.8. I put the OS X on the 60 gb.  I upgraded  
 to OS 10.2.8 about a year ago.
 Recently I noticed my HD(s) sounds a little off. Louder than  
 normal. No problems yet. Also I am now down to 7.4 gb  space left.  
 on the larger drive. I do some picture and sound work.

 I want to replace both hard drives with bigger, faster, quieter 200  
 GB range HDs. Of course I want to keep what data, settings, apps I  
 have. I have been studying about cloning my present hard drive(s).  
 But, I am not sure if I can put the size (200 or more) into my  
 present machine as it is now.

 Can I do the bigger drives with my present OS? Do I need to go up  
 to 10.3 or higher? Is cloning a good way to go?

 TIA.  Jim

Hi Jim;

A clone copy to an external HD would be the safest thing you could do.

It should (people can sometimes screw up the simplest tasks) be  
'Bootable', which will let you get back to 'square one' without  
problems.

[I.E. --- Get an external 'FW case/200GB Drive'    Clone the 60  
GB drive to a 60GB partition on the 200GB drive. Get out the screw  
driver, and swap the 60GB  200GB drives (200GB in system, 60GB in  
external case.]

At that point, you SHOULD be able to boot from the internal 200GB  
drive and be exactly where you were. (Except for now having 200GB  
internally.)
IF THIS doesn't work, carefully restore the 60GB to it's internal  
status, and tell us what you DID do, and results.

Chuck D.
