There you can read some of the information on the typical model:
https://everymac.com/systems/apple/i...800_17_fp.html

I didn't see it mentioned what size your SCSI hard drives are, and you will probably notice that not all of those iMac models will support "big drives".

Also, some of the models also have other limiting factors and can be quite fussy as to what goes into their innards. The same with the Mac operating system versions.

If it helps, there is a whole page on replacing hard drives in those models here if you haven't read it already:
How do you replace or upgrade the hard drive in the iMac G4 models? Which models support "big drives" and which do not?
https://everymac.com/systems/apple/i...ig-drives.html

BTW: is there some specific purpose or reason you are wanting to resurrect such an old iMac model???

If I recall, for the little I worked with any of those models, is that they could be very finicky and specific of what could be replaced.

I'm not even sure that Apple didn't restrict hard drive replacements to their own custom built drives.

Anyway good luck with your project, and maybe someone out there in Googleland has some of the answers you are looking for.

You may want to even consider getting and using an external firewire Drive as a boot Drive if you just need to get the unit working.

The imac that i am working is this model
"iMac G4/800 (Flat Panel) features an 800 MHz PowerPC 7445 (G4)"

The hard drive size is 40 gig western digital. i put in an 80 gig Seagate "working" and also a 20 gig seagate that had a os 9.2.2 installed in it as it was from a mac cube and none of those are booting on that imac.

someone posted earlier on the fan noise when i posted that the hard drive is spinning. yes the hard drive is spinning. i have power on the hard drive and trust me. when you hear a old hard drive spinning? you simply know that it is spinning. you can't mistake that sound.

Why i want to revive that puppy? well, good ol games and ol software of course. Plus. it looks better when it is working then a dead imac on the shelve collecting dust right?

mac looks better when it is a collectable and running like those i recently revived like my ol G3 tower? mac cube, G4 MDD, imac sunflower "ya i have 2", imac G3 and currently working on the Color classic.

I think you've probably answered all your own questions already.

1) Is the drive dead or malfunctioning? No. Multiple drives tested with same result.
2) Is there power getting to the drive? Yes, it's spinning. Power cable attached and working
3) Is the drive seen by the computer? No. Not seen by Disk Utility on boot CD

Item 3 is the key. The drive is not being seen by the computer. The most likely problem is that the cable attaching the drive to the motherboard is not installed properly, or it the wrong type of cable. If that's not it, then the motherboard could be toast.

You've also created some confusion by referring to SCSI drives in an earlier post. Apple switched to IDE (Parallel ATA) drives with the G3 models. A G4 iMac definitely does NOT use a SCSI drive. I don't think a normal SCSI drive will even connect with an IDE cable (different number of pins), so you probably do have IDE drives, not SCSI.

Correct RobAnd!! And I'm glad you made the correction, and I'd say that's a pretty damn good summary of the situation.

Maybe there is a unique forum somewhere for specialty or unique problems for those iMac G4/800 (Flat Panel) 800 MHz PowerPC 7445 (G4) mdels or any oddities they may have.

Otherwise I would say your corrected summary of the situation pretty well sums up all the problems.

PS: As for playing old Mac games, I'm sure I came across a post maybe a week ago of a new site that has adapted some sort of emulation for current Mac users to be able to play some of the old games.

I'm sorry I do not have any URL, but maybe that could be found with a quick Google search.

When I had time to mess around with older gear, I made frequent use of Low End Mac. One good place to start for iMac G4 issues.

And as for "why?" - it's an iMac G4! A bonkers, but brilliant, design from Apple. No other company would ever have put something like this on the market. I also have a 15" model in a box in the basement, with a dead HD... one of these days, I'll resurrect it. And I have a friend who has a the 20" model, which I'm trying to decide is worth the pesos he's asking for...

Some great points out there and most likely answered my question like you said. i confused myself with IDE and SCSI. i did replaced the ribbon "40 pins" and result was still the same. Now if it is the motherboard, i'm gonna have to investigate deeper in this. i do have a 20" that have a dead pram battery and i will replace it as i know that g4 is running.


for the time being? that g4 will remain on my shelve as a display, will try to fix it when i will have the time as i am getting a G4 mdd this week end
