Dragging it to the waste basket and deleting didn't work, as it reappears each time I restart.
OS9 appears as a hard drive on the desktop rather than as a folder in the system folder. Putting it in the trash is almost like ejecting a disc rather than deleting it.
You won't be able to delete the partition and claim back the disk space without ...
Actually you can - but only if you buy something like "Drive Genius" by "Prosoft".
But bear in mind that the G4 tower* has three Hard Drive bays so it may be an actual drive and not a partition.
*I'm assuming the OP is referring to a tower and not an iMac or iBook or something else with a G4 processor!
kweb - you'll need a HD with firewire as the G4 towers don't have usb2.0 ... you should be able to replace the existing cd drive with a dvd drive for about £25 - Apple generally used Pioneer drives so have a hunt for them ... I got my one from here : http://svp.co.uk/index.php?ref=buyers ... enter code 'theteamatsvp' and get another 10% off ...
If you can post the model no of your G4 (should be M/******) then can better advise on memory, etc
The existing cables will be OK - other models shipped with a dvd drive so the ATA flat ribbon cable and power cable should be all you will need to connect ...
Your G4 is a 'sawtooth' model, the max ram you can install is 2gb (crucial link for info: http://crucial.com/uk/store/mpartspecs.aspx?mtbpoid=2068351BA5CA7304) ... has ATI Rage 128 graphics card in an AGP-type slot ... will run *most* current software but not very quickly ;-)
Hope that's useful ...
