iMac g3 has shot hard drive

No It sound like the drive is dead. so it is too late to save anything from it.

Use the install CDs for your Mac to install OS X on the new drive.

ufortunately, you may have a failed or corrupt drive... you MAY, and no guarantees, you MAY be able to take the disk out, put it in an external enclosure, and TRY to recover information from it that way, but as the drive is faulty, this may not work.

If the hard disk has died, only a professional data recovery service can recover its contents, and those can cost hundreds or thousands of dollars.

A blinking question mark doesn't necessarily mean that the internal drive is dead, but usually means you'll need a compatible Mac OS 9 or X install disk.

The ? means the startup software -- firmware -- could not find a valid OS to boot. Could be a corrupt OS or a bad hd.

Sometimes if volumes don't appear in Startup Manager (what you get when you hold down the Option key at startup), you need to reset the Mac's PRAM, NVRAM, and Open Firmware. Shut down the Mac, then power it up, and before the screen lights up, quickly hold down the Command, Option, P, and R keys, until the Mac has chimed twice more after the powerup chime. Then, before the screen lights up, hold down Command-Option-O-F until the Open Firmware screen appears. Then enter these lines, pressing Return after each one:

reset-nvram

set-defaults

reset-all

"The reset-all command should restart your Mac. If so, you have successfully reset the Open Firmware settings."

You need an external Firewire drive to boot a PowerPC Mac computer [ a few G5's will boot from USB ].

I recommend you do a google search on any external harddrive you are looking at.

I bought a low cost external drive enclosure. When I started having trouble with it, I did a google search and found a lot of complaints about the drive enclosure. I ended up buying a new drive enclosure. On my second go around, I decided to buy a drive enclosure with a good history of working with Macs. The chip set seems to be the key ingredient. The Oxford line of chips seems to be good. I got the Oxford 911.

Has everything interface:

FireWire 800/400 + USB2, + eSATA 'Quad Interface'

&

save a little money interface:

FireWire 400 + USB 2.0

This web page lists both external harddrive types. You may need to scroll to the right to see both.

The latest the hard drive enclosures support the newer serial ata drives. The drive and closure that I list supports only older parallel ata.

Here is an external hd enclosure.

FireWire compared to USB. You will find that FireWire 400 is faster than USB 2.0 when used for a external harddrive connection.

The disk loader is dead

What do you mean by this?

( disk loader would be some software/hardware which reads in data from the harddrive. i doubt you mean this. )

What do you do with the machine? What happens? Describe all steps.

What do you want to do?

The next step is to replace the hd or get an external firewire hd.

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. People have put larger drives in the machine, but only 128gig is usable. People have reported problems with small odd size drives, for instance 3gig.

For drives greater than 128, I suggest you create a 127gig partition and leave the rest of the drive as free space. That way you will not have to worry about the boundary conditions.

Did you set the harddrive to master? Master is a must. Cable select doesn't work. You need to set the hard drive to master mode. There is usually a label on the hard drive that tells you what jumpers you need to set. If you are not sure, give us the name and model number of the hard drive and usually someone will be able to tell you how to set that drive.

Did you check all of the cables? Put everything back and verify that all works.

Try holding down the option key then power on. This brings up the startup manager. Click on your hd. Click on right arrow key.
