My old Bondi iMac slot-loading G3 has suddenly lost 10GB of hard drive space. It was a 20GB unit since purchase, I continue to use it for some music software and haven't installed anything new on it for years. Can a section of the hard drive just disappear/go corrupt? I was saving files the other day and got an "out of disk" space error and thought "What?!?!" I checked the computer and there is now only 10GB of hard disk space available. No partitions or anything like that have been made, computer works fine except for the fact he's suddenly a little thinner! Any ideas?

iMac, Mac OS 9.2.x

    A program like Photoshop might have temporary storage space allocated to it in its preferences.   Or virtual memory might eat up hard disk space from the Memory control panel.     Or running a big program might take up a lot of memory if the virtual memory not setup or its memory allocation in the Finder Get Info window allows it to eat that much memory.  Directory issues could make disk space disappear, for that you might need an old copy of Disk Warrior 2.1.1.

    Well if Disk Warrior can't repair the directory, it usually is sign of impending doom for the hard drive.

    When was the PRAM battery last changed? That would be related to the clock issues, but might be causing other problems if it's too weak.

    This. The PRAM battery would cause the time issues ("Your computer is set to a time before 2001.")

    Also, it could be to do with temporary files from programs (i.e. not virtual memory).

    Finally, if none of this works the HDD may be dying and this is causing the errors (I have seen these symptoms before on a G4/450). Can you hear a clicking noise when you use the computer?

    How to upgrade slot loading iMacs


    There are two assemblies with the iMac G3. The crt and the computer. The crt is fully enclosed. The computer is a tray that slides off. Working with the computer tray should be safe.


    You need to get the 3 and a 1/2 inch ATA harddrive.  They are also known as parallel ATA or PATA. The iMac was designed to take a maximum drive size of 128gig.  The 120gig drives are the largest readily available. Odd ball sizes do not work like 7gig and 13gig.  Pick a size that appeared on the iMac G3 or is a common size greater than 20gig like 40, 60, 80, or 120. Sizes larger than 128 will work but you can access only the first 128gig without buying additional third party software.  For very large hd's, format the drive for 127 gig or less.
