Cannot upgrade to Leopard from Tiger??

illegal Alien,

Do you have any Previous Systems folders?

If not, WhatSize 10.3.92, will help you determine what is happening.

illegal Alien,

How would I reformat the hard drive. Would that be a quick fix.

Before you consider that action, I would try to determine why your drive has so little storage space remaining.

Could it be a faulty drive.??

I doubt it, but open Disk Utility (First Aid) and click on the startup disk...It will be labeled something like XXX.X GB XXXXXXXXX

What is the S.M.A.R.T Status at the bottom of the window? It should say Verified.

You should also use the repair function of Disk Utility on either your Tiger or Leopard install disks, by using the procedure described in Resolve startup issues and perform disk maintenance with Disk Utility and fsck.

The Repair Disk function link by Dr. Smoke will also elaborate on the procedure.

illegal Alien,

Disk Utility will not open. Says error... Oh No!!! Now what?

1. Do you have your important files/documents backed up?

2. What Repair Disk procedure/installation disk utility (Tiger or Leopard) did you use?

3. What is your S.M.A.R.T. status?

4. Did you try to use WhatSize 10.3.92?

5. You may need to use Disk Warrior before you attempt to install Leopard.

6. What type of Leopard installation option are you attempting to use? 
 - Archive and Install?
 - Erase and Install?

7. Can you still start your computer with Tiger?

8. Do you have any Previous Systems folders on your Macintosh HD?

;~)
