DiskWarrior CD stuck in iMac DV 400 SE

I have tried to help a friend who found he has a 400 Mhz iMac G3 DV, (slot loading DVD with 2 Headphone sockets on front) to clean up the drive, speed it up a bit and load some useful software.
It is running OS 8.6 (is this the best OS to keep it at OR can it run OSX?) and has 198 Mbs of RAM installed. I have got stuck - when the DW had finished I clicked Restart and the iMac sounded the Hero chime as if it was Restarting but it subsided into a sort of sleep-like sate, with the Power light pulsing.
The DW CD is still inside - How do you get it out? and each time one presses the Power button to Restart it sounds as if it will but then seems to "spin-down" and again sit with power light pulsing.
I have tried Option start - NO GO
I have tried C start, in the hope it would start from the DW CD but no luck.
I have tried Shift start as if I was starting without Extensions - this time at least it got just a little further but again went to sleep.
I have unplugged power and replugged - no go.
Nothing seems to get me anywhere. When I opened the "bottom" hatch I saw a strange nylon "key" attached to a little arm attached to a black plastic cable that disappeared off towards the front of the machine, as if when I pulled this the CD might pop out - I didn't pull it but what is this, can I find a plan of the layout inside, to find the Eject button for the CD?
Any help would be terrific - I've forgotten all my OS8 keyboard commands too.

philip howe...
What version of DiskWarrior was used in that iMac? If it was Version 3 (yellow and white cd) there may be a serious problem. It contains Mac OS 10 booting resorces and can mangle your system if firmware was not updated.
Version 2 (silver tone/red CD) boots up in Mac OS 9, so it should be safe then. You had to encounter some other hardware problem in the process.
Please post back with your details.

Can't install OS 8.6 on iMac "DV" (400) Slot Loading?

I have an iMac "DV" (400) Slot Loading that I am trying to install the original system on (8.6, if I'm not mistaken). It has 128 mbs of RAM, a 10 gb HD, and currently no system installed on the hard drive. I have updated the firmware to 4.1.9.
The problem is that the iMac won't boot from the install CD for me to do the installation. The iMac used to have OS 9 installed on it, and when I tried to run the installer with the computer booted from 9, it told me it couldn't run on this machine. I believe I have the correct installation CD. I have also tried a couple of other installation CDs, and neither 8.5 or 8.6 will boot this computer.
Is there a way I can get 8.6 installed on this machine with the 8.6 CD, or is it just not possible for me to install 8.6 any more?

Hi Jon
Load the install CD into the Mac then power off (with the CD still inserted), on rebooting but before the chime, hold down letter C on the keyboard, that will boot from the install CD to let you do a system install.
You did not note whether you had other programs/files on the iMac that you want to keep, but if not, I would suggest that you do a complete "clean install" by re-formating/initializing the HD, then install the OS.
I would also suggest that you partition the HD into 3 (or more) partitions, 1 for the main system, 1 (or more) for your other programs/files and 1 for a "back up system", the logic being the main system is your default "boot-up" while the "back-up" system is what you boot to do maintenance/de-frag etc on the main system with a utility such as Norton's Utilities or similar.
I would also suggest that you have a copy of Norton's (or similar) on both systems, that way you can "chop and change" systems to do the maintenance. Proper maintenance/de-fraging cannot be done to the "boot-up" system that you boot from.
Hope this is of some help.

Please help, need to upgrade from 9.2.2 to osx 10.4 Tiger on imac g3 400 dv

Hello, I would greatly appreciate assistance to upgrade my operating system from 9.2.2 to osx 10.4.10. I have gotten the firmware upgrade installed to 4.1.9. Can anyone tell me what else I need to upgrade to have this computer able to install Tiger 10.4, on an imac g3 400 dv slot loading.....
Right now when I try to install the disc 10.4 using the option key at restart, it wont load the install disc. Any help would be appreciated , thank u in advance!!!!!!!

Hi, thank u for responding, my harddrive is 10 gigs, and my memory ram is only 64 megs, I ordered 2 512 mg from 18004memory.com and it didnt work , the computer said there was a memory issue. So I returned the memory back to 18004 memory.com...... I will neve ruse them again , because on their website they stated its guranteed to work and is compliant with imac 400 dv. They stated they will send me another set from another manufacturer, but to return the memory first.....
I know I meet all the requirements for tiger , except for the ram which apple says I need 256 mg,
But I was referring to any firmaware upgrades or bios upgrades or any of those type of programming upgrades to ready it for tiger, I know I installed the 4.19, and went from os 9.0 to its current 9.22, I think that alone was 5 upgrades. I think I might be missing an upgrade or maybe not. I will run the utility u posted and thank u for that.....
Apple told me that I can installl tiger 10.4.10 on this computer.
The install discs I bought on ebay state imac MAC osx install disc one and there is and install disc 2, it says AHT VERSION 3A127, and dated as produced in the year 2007. it colored grey , but doesnt have the black X like someone else posted it should have
Oh and it does open the files in 9.22, it does mount, and it does have folders,
Thank u for ur help as I progress to ultimately saving this imac....
many thanks!!!!!!!!!!!!!!!!!!

IMac DV/400 will not read CD's since I installed Panther

Hi,
A customer's iMac DV/400 with 384 MB RAM was running OS 9.2.2. We decided to upgrade his OS to 10.3 (firmware was already up to date 4.19) After the first CD finished and it restarted and asked for disk 2, it would no longer read ANY CD's. In fact I had to cancel the rest of the install, because it wouldn't even recognize disk 2. What can be done to fix this? nothing has changed except the OS. I made the Mac boot from the old 9.2.2 again and the CD's read fine.
HELP!

If the DV ROM works with OS 9.2.2 then there is nothing wrong with it. Try installing Panther again. What is the size of the hard drive? Does it have enough free space?

UPGRADE Panther or Tiger on Imac DV 400?

I am trying to determine which OS would be the better choice for my computer. I have been running 10.2.8 for a few years, but I just bought photoshop elements 4 and now I see I need 10.3 or better. I can use the educator discount from Apple for Tiger, or probably find an old retail disc for Panther, but I am wondering (for those who've tried with a similar system), which OS works better?
iMac DV 400 Mac OS X (10.2.x) original 10G hard drive, 576 ram

It really doesn't matter which one you decide to use. However, that original 10G hard drive must be getting a bit cramped. Without having the RAM up to full capacity (it will take two 512 MB chips), you are overly depending upon virtual memory, which needs lots of free hard drive space to write to. Unless you are doing frequent restarts and keeping lots of hard drive space freed up, you could start having problems, and possibly losing data.
Before considering upgrading the OS, it would be best to consider upgrading the hard drive and/or installing more RAM.

Can't install OSX on iMac DV 400

I have a Blueberry iMac DV 400 with 512MB/10GB and a clean install of 9.1. The hard drive was formatted journaled with Disk Utility from the 10.3 install CD.
I've tried installing 10.3, 10.3.5, and 10.2 with no luck. When trying to install 10.3, I get to the part of the install where it's reading packages and the screen goes blue with the black spinning dial gauge. When I tried to install 10.2, I got the spinning beach ball and then a black screen that said the install could not continue and I needed to restart.
The computer runs fine under 9.1. My niece had been using it for years until she upgraded to an iMac G5
Anyone have any ideas what is causing this?

Thanks. I think I have plenty of hard drive space as it's a 10GB drive and with only OS9 on it, there's about 8GB free space.
However, that article "Mac OS X: Troubleshooting installation and software updates" lead me to this one:
"Troubleshooting Mac OS X installation from CD or DVD"
http://docs.info.apple.com/article.html?artnum=106693
As suggested in this article, I will try copying all the files on the CD to the hard drive to check the optical drive. If that works OK, then I'll pull the RAM one DIMM at a time to check that.

Success with iDefrag and DiskWarrior on my Intel iMac! (indirectly)

Had some very good success using iDefrag and DiskWarrior on my intel iMac, both of which do not run directly on the intel platform yet. As I had observed a gradual (modest) slow-down over the course of the past month since I got my iMac, I couldn't help but try to figure out a way to defrag and optimize the hard drive since I had over 125GB (including quite a few large media files, and a couple system updates, both of which tend to cause fragmentation). So, after doing two independent backups on separate external HD's, I ran iDefrag on my iBook and defrag/optimized the iMac's hard drive using Target Disk Mode. As expected, the hd was VERY fragmented - and the process took overnight to complete. Being as careful as possible to ensure no problems, I then ran verify disk and repair permissions on the iMac's hard drive, and no problem. Did notice a very meaningful increase in responsiveness and speed on the iMac, even more than I would have expected. Since I historically always ran DiskWarrior after doing this exercise on my PPC mac's, I decided to attempt the same here. Since I (and others on this board) have been unsuccessful in running DW3.03 using the iMac in Target Disk Mode, I decided to update backup drive #1 post-iDefrag, and was then able to mount this drive (backup#1) and run DiskWarrior on it from the iBook. No problems were detected which was great news, but the I had it write the new index/directory files. I then sync'd back to my iMac's hard drive (from backup#1 to iMac HD) and observed that a number of files were updated most likely as a result of the updated directory/index files from running DW (I use FolderSynchronizer to sync). So keeping backup#2 of the pre-iDefrag/DiskWarrior for a while, but so far so good, and a very meaningful improvement in performance. So the experiment seems to be a success.
DISLAIMERS: If anyone does "try this at home" please backup and re-backup before attempting. In addition, please note that Coriolis is in the process of developing an intel build for iDefrag and probably recommended in general to wait for this update.

Thanks for this posting and the good advice. I put in some time chasing the 801.57 gb limit before finding this thread that steers in the direction I see now I must persue, a new enclosure (modern day version rather than 5 year old technology -- yes, the old external drive has the Oxford chipset mentioned repeatedly in other threads) to go with my new drive. Would have been better off $$-wise to have purchased a complete unit, but this is so much more fun on a Monday evening.
Great being here with you all!

Upgrading iMac G3 400 DVD slot-loader to Tiger

My iMac's hard drive is dying and have purchased a brand new Seagate Barracuda 7200 8MB cache 120GB ATA IDE hard drive on eBay to replace it (haven't received it yet). Also am going to replace the PRAM battery and add 256MB of RAM. The Mac currently only has 64MB of RAM in it!! Will add more RAM when I can afford to...
I have checked the System Profile before the hard drive gives up the ghost and the firmware will need updated. The Mac has OS 9.0 on it. Had to buy a OS 9.0 full version disk on eBay (to install on the new drive) and happened to find the 9.2.1 update CD at a garage sale last year! Have downloaded the 9.2.2 update from the Apple website.
After I replace the hard drive and install OS 9.0, the 9.2.1 and 9.2.2 updates and the firmware update, here is my question:
Can Tiger be installed after the above installations, or would I have to install Jaguar (that's the other version of OS X I have on hand) before Tiger can be installed?
I want to use the iMac as an "all-in-one" DVD player for the most part. Tried playing a DVD on it before the factory hard drive started messing up again, but it couldn't find the video card or something. Am sure the hard drive is losing files as it's slowly dying...
Thanks.

Hello and Welcome to Apple Discussions.
It's far better to start your own thread then resurrect one from the end of last year - if you do you'll get several opinions.
10.2.8 is a useable OS and if you have no legacy OS9 applications then you don't need to keep the OS 9 System Folder or Applications (the former of which allows OS X to run Classic mode). Just delete them. Before you delete OS 9 boot in to it ( Apple Menu > System Preferences... > Startup Disk ) and ensure that you have installed this firmware update (link). Technically it is required prior to OS X but will cause serious harm if you go above 10.2.8 without it. After that you can delete OS 9.
This iMac is going to be a pretty lean and not so mean iMovie machine. You might wish to consider giving her the full 1Gb of RAM and 128Gb Hard Drive.

IMac G3 400, clicking noise w/new 120GB when trying to sleep

iMac G3 400, OS X 10.4.6 356 MB ram. clicking noise w/new/used 120GB when trying to sleep. Used drive came out of a Lacie 120GB D2 that was only used for backups once every month. Ran Tech Tool Pro advanced test and everything checks out. It is almost like it is clicking down to sleep and it starts back up again and shuts down again ect... The clicking is about every 3-5 seconds. Any ideas?? I don't want to stick my old drive back in.

Does the machine in question have firmware 4.1.9? I've observed strange behaviour with slot loading iMacs not running the latest firmware with OSX installed. Granted, most have been monitor/optical drive issues but I don't think your problem could be completely ruled out as a possibility. System Profiler will tell you the version in the Boot Rom section. I discovered a 400MHz indigo with an 80GB WD and the same obnoxious affliction today. I'll see what I can do to resolve it and let you know.

Tiger Install on iMac G3/400 DV reboot problem.

Hi there, first time post .
I obtained a slot loading G3/400 DV. I replaced the 10GB that was inside it, with a 80GB. It has aproximatly 320MB of RAM and does have firewire.
I believe the CD-ROM is toast, as it will not boot of a CD when 'C' is held down. I have managed to install OS 9 onto it, by transfering a clean install of 9 via firewire and upgraded it too 9.2.2. Everything worked fine. System boots fine.. etc..
I have just bought a DVD copy of Tiger for my Cube(needed 9 before for, my UD12X12 tablet). I read it is possible to install OS X via Firewire. I held down T and all that, and put X onto the 80gb via the DVD from the cube. Now, when I reboot the iMac I get a flashing folder with a ? on it, and will not rebbot on a Option hold down.
What am I doing wrong, please help.
PS: The previous HD, has a dual boot with OS X and 9; but it has a admin lock on it, and is only 10GB.
Thanks

I am not certain, but your 80 GB might be a machiine that requires X be installed on the first 8 GB's of a drive. You may need to partition.
Keep the machine in target mode, and see if the cube starts from the installation. This would be a good clue, if the install was good.

Turning iMac DV 400 (G3 slot loader) on via the Apple Pro keyboard?

I was looking at my iMac's Lowendmac profile (located here: http://lowendmac.com/imacs/400.shtml) when I noticed right at the bottom of the page under "Cautions" it mentions:
"You must have the keyboard plugged directly into an iMac USB port to boot with the power key (Eject on the Apple Pro Keyboard); it will not work if the keyboard is attached to a hub."
I never knew this. Before I got the iMac I had an old slow Performa LC630 and it did have a power key on the keyboard so when I went to the iMac I was a bit miffed to find the Pro keyboard didn't have such a feature (not that it mattered a great deal of course, I just always liked power buttons being on the keyboard).
Reading this bit of info though obviously made me excited since in all these years that I've owned the iMac I never knew it could be turned on by pressing eject.
I tried it. Nothing happened. The keyboard is plugged into the main USB panel on the actual iMac too, I tried both slots. No ball. Pressing the eject button doesn't turn the iMac on.
Is this article simply incorrect or is there something I'm missing?

Perhaps the article meant to indicate that those Apple USB keyboards having a power button and the Apple Pro keyboard having the media Eject key must be plugged directly into the computer's USB port and not into a hub, for functionality of those keys. If the Eject key served the same purpose as a Power button, I'd expect to get a prompt asking if I'd like to shut down the computer, every time I ejected a disk. I just connected a Pro keyboard to my iMac DV, and pressing the Eject key didn't power ON the computer.

Help! Disc Stuck in iMac!

I have a iMac blueberry 333mhz, and a CD is stuck in the slot. I've read through this area and have tried the following but with no success:
1.Restart with Mouse button held down
2.Open firmware and type in eject CD
The drive makes a whirring sound as if it is trying to eject the disc, but it doesn't come out. Is there a hole that I can put a paperclip in to eject the disc?
Are there other ways to get the disc out?
Thanks for any help!

Hi Kathy
Apple tells you to put RAM in through the little door - that's why it's there.
Just open the door, held the RAM carefully (without touching the gold strips) and press it into the slot untill the 2 tabs click in at either end. Then try and pull it out. If it doesn't come out it's in and seated properly. Takes about 30 seconds.
The other reeason for the door is to fit an airport card and card adaptor.
It's only the battery where you are told to open the computer up. Although there are quite a few on the list who say that it can be done through the door, it's very easy to break the battery holder getting the old battery out if it is reluctant to come out.
If you check the help files for upgrading your mac it should show you how to add more memory.

CD Stuck in iMac Disc Drive, Mechanical Problem

I, surprisingly, could not find a good solution for this on Google because of the vast number of people with software-related disc jams and bad tutorials.
I put a Windows 2000 recovery disc in my Mac so I could test to see if I could make a disk image from it and mount it as a real CD...anyway, I should have known that the HP-made disc would get stuck in my drive. It felt kind of strange as if it was the wrong thickness.
Now, I cannot eject it nor can I see the disc trying to be ejected due to the flaps on the drive blocking it. I tried feeling around with a credit card, but there was a metal bar blocking the disc. If I try to eject it, it keeps trying over and over again but can never eject it.
I'm looking for a hardware-related way to get this out. I know about the "click on bootup" and "force eject" methods, but those will not work.

I can't recall exactly what I did to make the credit card work that first time. About 1/3 the way from the edge of the slot (top of the slot on my iMac), you can feel some mechanism that's closed normally. When you go to eject the disc you can feel that mechanism open and you can hold it open using the card. I recall it took a lot of fiddling to get the thing to pop out, so I can't say exactly what I did. You can try to use the card to sort of coax the disc out or push it up or down, depending on which way it's having trouble ejecting...
Sometimes you can see the disc poke out a little only to do back in. In those times I've thought about getting a pair of tweezers to grab it, but usually didn't end up having to. Could be a two-person job.
If nothing works, before taking it to a shop I'd try opening the bezel. I don't know how or why but that really did the trick for me last time I went through this.

IMac DV 400 & Samsung HD ?

Hello,
Can I replace the original hard drive of my iMac G3 DV 400 with a Samsung SpinPoint V40 SV6003H (3.5", 60 GB, 5400 rpm, ATA-100 - 40-pin IDC - 2 MB buffer) ?
Thanx in advance,
PowerBook G4 Alu 15" - Oct. 2005 Mac OS X (10.4.8)

Yes, any ATA133, ATA100 or ATA66 drive will slow down to work on your iMac's ATA33 bus. Nowadays 5,400rpm 2Mb cache is a slow hard drive. You should really be looking for a 7,200rpm drive with 8Mb cache to give yourself a speed boost. BTW you can install up to a 128Gb drive.
Here are the installation instructions (link).
Put the old stock drive in an External Firewire HDD Enclosure to restore your data back to the internal and then act as an essential back-up device.
Let us know how you get on.

DiskWarrior CD stuck in MBP

I've got a bad DiskWarrior CD, I know that much. I tried booting one MBP off it, holding down the C key to force boot from the optical drive, but it only hung with a gray screen, never the OSX symbol. To troubleshoot whether it was computer rather than the disc, I tried the same thing on a different MBP. And I got the same result. Only this time, I can't restart and eject the CD. It won't let me. I've tried zapping the PRAM and have restarted several times holding the trackpad key down, and holding the "d" down (which forces the machine to boot off the internal drive). None of that works. I just get this gray screen.
Any ideas?

I don't suppose there's some easy-access hatch I can open up and click some manual eject mechanism inside?
No, have you tried holding the left button down while booting of a standard wired mouse?
This is supposed to be a low level hardware level cd eject method.
Perhaps you didn't hold the trackpad button down hard enough?
It could be the new Mac's trackpads are different, Apple is loading higher level firmware into everything and that could be denying your ability for a low level cd eject.
That said, I've tried all of your helpful tips. (Thanks very much!) Tried starting up holding D, then Option, then command-S (to start in single-user mode). All with the same result: The chime rings, the screen turns on as gray, I can hear the CD spinning up, and after a while the CD spins down. And that's...it.
This old Disk Warrior disk seems to have done a number on your EFI firmware, it's set itself as the first boot option, borked your EFI/EPROM based firmware (normally copied from your hard drive) you need to prevent the machine from reading from this cd disk.
This may require you to, upon booting, to place pressure on the disk edge so it doesn't rotate at the proper speed, slowing it down, this might make the disk be ejected as unreadable (so be prepared), at least it won't load into RAM which is what you want, you want the hardware firmware to recognize your boot drive as first boot) and use that instead to load the EFI firmware, so you might have to do the slowdown trick twice if the disk doesn't eject.. If you get into OSX, get that disk out with the above methods within OS X. Then reboot the machine two more times, this should load the EFI firmware from your hard drive back in the EPROM.
You should contact the folks at DiskWarrior and tell them what occurred and how to get the disk out and repair the damage as well. However since it didn't boot, it likely didn't do anyhting harmful to your drive, just to your EPROM which will get loaded from the hard disk again once the cd is out.
Use the above methods only if your out of warranty/AppleCare or at your own risk, I haven't attempted anything ike this, but I understand the boot process to some degree.
http://www.macyourself.com/2009/05/01/the-ultimate-guide-to-ejecting-a-stuck-dis c-from-mac-superdrive/
If you find Linc Davis, trouble him with your problem, your EFI is borked by a old DW disk that set itself as the primary boot, nothing works, not option or command s etc. You need the disk out so the firmware reads load the EFI of your hard drive again.
Good Luck.
