Can anyone confirm that any or all of the Western Digital Models WD5000AAKB through WD800AAJB in the Caviar Blue Range would be suitable replacements for my current 80.0 GB Ultra ATA/100 HD (7200 RPM)

iMac G4, Mac OS X (10.4.11)

    As long as the drive is PATA/IDE, it should work. However, some Gen1 iMac G4s may not have support for drives larger than 128GB. Some users report that their Gen1 units will support larger drives but it seems a little "hit-and-miss." Later iMacs are not limited.

    Than you for your reply. I note from the Technical Specification obtained using the Mac Serial Number that the 'Build-to Order Options' shows a 160 GB 7200 limit to the HD which, presumably, sets the limit for any capacity increase?

    A logical conclusion but not true: the limit is in the ATA/IDE controller. The BTO options were more about what drives they could buy at the time.

     

    On a 1.25GHz iMac G4 you can install any just about any size hard size you can find. I installed a 320GB WD drive back in 2005 in my 1.25GHz iMac G4 and it's run very well ever since.

     

    cheers
