CD/DVD not recognized when booted in OS 9

Hi,
I have a PB G4 667 titanium (the gigabite ethernet model) that can boot into OS 9. I normally run OS 10.4.5. I recently re-installed OS 9.2.2 using a generic install disk (not the one that came with this specific model). It boots fine into OS 9, but it will not recognize CD's or DVD's or some extensions, like Apple DVD player (which says it is missing a .lib file.
I also had a new upgraded SuperDrive (MCE Technologies) before I had to re-install OS 9. I didn't try to run OS 9 and see if the drive worked after it was installed, so I don't know if that might be the problem. I tried to load the driver into the extension folder, but there was no folder called "Supporting Authoring files" like the read me text said there should be for OS 9.
Any suggestions as to how to get OS 9 to recognize my CD/DVD's?

HI, marbot61. It sounds to me as though the problem is not that discs aren't recognized, but that your drive itself is not supported by your OS 9 installation — and perhaps it isn't supported in OS 9, period. Call MCE and ask for help setting OS 9 up to support the drive.
If you used a model-specific OS 9 installer disk that came with some other Mac, rather than a retail OS 9.2.1 disc (white, with a big gold 9 on its label) or the installer disk that originally came with your Powerbook, that may be the problem. It may be essential for you to use the disk that was shipped with the Tibook to install OS 9 on it. You should never expect to get a functional OS 9 installation from an installer disk that is specific to any model other than the one you're installing it on, and MCE will be justified in telling you they can't support your drive until you have a proper OS 9 installation on the Powerbook.

New hard drive in, not recognized when boot from DVD

Well, I installed my new Seagate ST3750640AS, 750 GB Baracuda and when I boot from the Tiger install DVD, there is no Hard Drive listed. What could have gone wrong. I have an early model G5 iMac.

Are you sure the cable is connected? Look at the [DIY|http://www.apple.com/support/manuals/imac> for replacing your drive and see if there's anything you may have missed.

Hard Drive not recognized when booting from XP CD on docking station

The hard drive on my X60 failed to the point where I couldn't recover and reinstall the image. I have backups of all my data and a docking station so I didn't sweat it. Bought a new drive and installed it and this is when the trouble began.
I created an XP CD with SP2 slipstreamed in to make sure I have the latest drivers. I boot from XP CD and everything works until I try to install Windows. According to the installation CD there is no drive installed!
I reinstalled the drive to make sure and this time I booted off of Ubuntu Linux which installed flawlessly. That leads me to believe that there is a driver problem with Windows.
I need help! I would like to install Windows on the machine but nothing I've tried works.

Standard Microsoft XP SP2 does not come with any SATA device drivers.
You have two options:
Go into the T60 BIOS and switch the SATA controller mode away from AHCI to "IDE" mode (or pehaps its "legacy" or "compatibility" mode - I forget what specific term is used in a ThinkPad BIOS).
Find the SATA device driver for XP (it's probably in the Intel Chipset driver download) on the Lenovo X60 support web site, download it and install it using the additional driver installation option which is offered right at the start of an XP install.
If you chose option 1, remember to switch the SATA controller back to AHCI mode in the BIOS after you have installed the SATA device driver.
Cheers,
Bill

[CLOSED] CD/DVDs not recognized (hal-less KDE)

Hello everyone,
after the last system upgrade last week CDs and DVDs are not recognized when I insert them in the drive.
I'm running hal-less KDE 4.6 with udisks installed.
I removed hal after the upgrade, however the drive could not recognize the disks even when hal was running.
I searched the forum but haven't found any discussion reporting the very same problem.
Can anyone help me to debug this?
Thanks!

I had the same / similar problem. Just that given that I build my own kernel I thought this was what was causing it. That's why I rebuilded the kernel and enabled ISO and UDF modules in Filesystems. If you're using the standard kernel I have no idea what could be the problem.

[SOLVED]Hard Disk not recognized when installing

Hey all, I'm just starting with Arch and I've had some trouble installing it on my Acer netbook.
My first installation went well except that I had forgot to download the wireless tools so I decided to do a fresh install as I had no access to a wired connection at the time. The second installation attempt must have had some error on my part as Arch failed to start after selecting it from Grub, saying that the kernel was not available/not recognized.
Now my subsequent attempts at installing have failed because the hard disk is not recognized when running either cgdisk or cfdisk. Instead of showing my hard drive partitions after running
cfdisk /dev/sda
it shows my usb drive. If I instead use
cgdisk /dev/sda
it displays an error saying that the disk is damaged or not recognized. When I first saw this I thought my disk was failing, so I tried #! to see if it would show the same error, but it was able to recognize the entire disk and install correctly. Now, even after having the entire disk formatted as ext4 with #! installed, cgdisk is still giving me the same error about a damaged disk.
Am I doing something incorrectly or is there a fix for this? I haven't been able to find any information about this after a good while of searching.
Thanks for your help.

If you mean by trashing the USB flash drive, that it will delete all data and partitions on the selected drive it is correct, because:
dd if=/dev/zero of=/dev/$disk bs=4096 count=1
- this will delete all partition-table data
sgdisk -o /dev/$disk
- this will clear out all data. This includes GPT header data, all partition definitions, and the protective MBR.
/dev/$disk
- this will make you enter ncurses-based GUID partition table (GPT) manipulator, where you can create new partitions
You should only do this if you are certain of what disk it is.
Now if when you said this, you were meaning it will became broken, then it may be a special kind of usb drive because i've donne it many times and i've not broken any.
srs5694 wrote:My guess is that either your hard disk has become /dev/sdb (this can happen in some cases; disk identifiers aren't really fixed) or you're missing a driver for your hard disk controller because you've booted a different kernel or a different initrd file. Another possibility is that there's a hardware fault -- probably a loose cable -- that's preventing the kernel from seeing the disk.
If the usb drive is not where you installed arch, then you need to find if there are more recognized drives:
lsblk | grep disk
And see the uuid of the root partition you want, and add it to your bootloader boot line:
blkid /dev/sdxx

Disabled ipod not recognized when plugged back in to itunes.

Daughter's disabled ipod (second time) is not recognized when we follow instructions to enable it and plug into itunes.

HT1808 is the article you need to follow. You need the section labeled "Placing the device into recovery mode."
You need to power the device off. Once the device is off press and hold the Home button or the button on the front of the device and while holding the Home button plug in the device and continue holding the home button until you see the image below.

Is the iPod Touch specifically stated as being compatible? Have you tried to perfrom a hard reset of the iPod with it still connected? To do this, press and hold both the Sleep/Wake and Home buttons together long enough for the Apple logo to appear.

My DVD drive is now not recognized in boot camp.

I just found the Matshita DVD-R UJ-898 is no longer recognized in Boot Camp Win 7. Tried uninstalling in Device Manager but the driver fails to load upon restart and also fails when trying to update. The DVD drive works fine in OSX Lion so I know the drive is ok. It worked fine when I first installed Windows 7 in Boot camp last year. This is an early 2011 macbook Pro 17 with Lion. All updates have been installed. Hadn't used the drive in Win 7 for a long time so not sure when it ceased to work.

Found the solution. Microsoft Fix-It found and made the driver repairs automatically.

AFTER 10.5.4 UPDATE "MEDIA NOT RECOGNIZED" WHEN BLANK DVD ON DRIVE

Hi, after update 10.5.4 my CDs and DVDs will be read and play in the Optical Drive, But when I insert a blank one, any kind, the finder will open and when I select to mount it "media not recognized" comes up. I have the same DVDs that Ive been burning to till this update with no problem at all.
I already did permissions repair.
Please help.
Many Thanks!

I have a problem pretty much like that too, I updated my mac, and now my superdrive won't read my discs, but unlike yours, it spits the disc out.
I did find out that it can recognize DVD +R, sometimes, but it can nolonger recognize DVD -R.
Also my superdrive makes a sound like this: http://www.imeem.com/people/2tOboJ/music/gQwemcsY/superdrive_problemwav/
Sorry if I'm hitching on your post Alex, I also have another problem, and that is I can see the "reply to this post" icon but I cant see any icons that say "post new topic" anywhere, I wonder why. =(

DVD--not recognized AND stuck in drive

I've had trouble with my G4 not recognizing DVDs. I just put one in that was burned at a store with a friend's videotape--it never showed up in the finder. When I launch Disk Utility, it hangs. I am using an older keyboard without the disk eject button; I can't get the disk to eject, can't drag it to the trash because it doesn't show up. When I reboot with the mouse button held down, the Mac won't start up--I just get a Windows-like gray screen of death.
I don't know what the drive is--it's an old Super Drive--because the Apple System Profiler also hangs when I click on the "Disc Burning" option.
How do I get the DVD out, and how do I get the G4 to recognize DVDs?
Thanks for any help--Bob

Hi-
Try and open the tower drive cover, and look for a small hole about the size of a paper clip, in the front of the dvd drive. Insert a straightened paper clip in the hole, and you should be able to open the tray.
You should then try your Tiger install disc. (While you're at it, boot from the install disk, and run Disk Utility to repair your hard drive).
If the install disk is read, then the drive is probably okay.
You may consider an "Archive and Install" reinstall of your OS X.
Prior to that, you may consider a reinstall of the OS 10.4.8 combo update:

Keyboard & trackpad not active when booted!

Got a white 2.0GHz Intel Core2Duo 13" with 1GB RAM and OS 10.5.8.
The keyboard and trackpad are suddenly locked when the the machine is booted. The cursor is in the same place after restart - not movable - but not frozen either. Because when I insert a CD or DVD it autostart the respective item, and the cursor becomes the spinning beach ball for some seconds....iow. NOT frozen. None of the keyboard buttons will work except the on/off button. So I thought for a minute that the keyboard was physically shortcutted. But upon restart, I was able to run a PRAM reset (Alt-Cmd-R-P) - also ejecting a DVD, that would NOT eject when fully booted....
So it must be a software related problem. Or is it a "panel lock" or "key lock" function that I've activated accidentally???
Thanks for any input on this. I will in the meantime try to restart from the OS DVD.

Some additional info:
System profile tells me it's a MacBook 1,1 with a Intel Core Duo (not a Core2) - if it makes any difference.
Well, I booted up from a Leopard install DVD, and everything related to keyboard and trackpad works. Run Repair Disk Permissions, and Verify Disk - just when I'm at it!
Restart from internal disk again....Nope. No keyboard or mouse action....
Time the reinstall the complete OS perhaps.

Keyboard and Mouse no longer recognized when Boot Camp'ing into Windows XP

Mac Pro early 2008, Mac OS X 10.6.2, all updates applied. WinXP SP3. Standard wired Apple smooth mouse.
I normally use Parallels 4.0 to access my Windows XP on this Mac. That's been working fine and continues to do so. I upgraded to Snow Leopard not long after it was released. My Parallels is set to use the Boot Camp partition as the basis for its virtual machine.
I haven't started Windows directly from Boot Camp in some time. It used to work fine also. I am not sure I have accessed it directly from Boot Camp since I upgraded to Snow Leopard.
In any event, when I try to boot into Window, my slim wired Apple USB keyboard and mouse are not recognized. I get to the opening Windows Log-In screen and at that point, I can't move the mouse cursor and I can't type anything into the Windows password input box. The red mouse laser light flashes once every 7 or 8 seconds but also doesn't stay on.
Starting Windows under Parallels still works fine. I downloaded the BootCamp 3.1 Windows 32-bit upgrade from Apple. I tried running it in Windows under Parallels. Something ran for a while when I did that but there was no installation screens or dialogs after I clicked the "run" button.
Not sure what to do next.
Thanks.

Adding to the above: I also tried plugging in an Microsoft USB keyboard at the point when Windows freezes at the Windows log-in screen. The keyboard is not recognized and the only way I can leave this screen is to power-off the computer.
