Combo Drive not recognized

My internal combo drive is not longer recognized by my Intel Mac mini. It does not show up in System Profiler under Disc Burning. Instead I have a message that says: "No burning device was found."
Incidentally there is an audio CD in the drive, which I cannot eject. Holding down the mouse button on startup has no effect. Resetting the SMC has no effect. When I startup with the Option key held down, I can hear the disc spin up very briefly immediately, but there is at least a 2 minute delay before the internal drive shows up as a startup option.
I connected a Firewire optical drive, which works, but DVD Player and FrontRow refuse to work to play DVDs and quit with errors. (I can play DVDs with VLC, however.)
Does anyone have any suggestions for something to try before I take it in for repairs? Thanks!!
Robert

Thanks for the link.
I tried restarting using Command-Option-O-F, even though this was said not to work on Intel computers. I'm not sure if there was any cause-effect, but this time the CD mounted on the desktop and the optical drive is now showing up in System Profiler, and I was able to eject the disk.
This may be some kind of intermittent hardware or software problem. I have my fingers crossed that it doesn't crop up too often.

IBook G4 Combo Drive Not Recognized / Freezes

Hello all,
I have a problem with my iBook G4 1.25ghz
I have erased and reinstalled the OSX do to a hdd error, something about the tree. I dont remember now.
It will intermittently freeze during boot, if I hit the case above the hdd it will unfreeze and continue loading. When the OSX loads (10.4.11) again will intermittently freeze (hit the case and it comes back to life)
It doesn't recognize the combo drive, I therefore cannot do a disc repair from Tigers OSX disc, nor can I load tech tools.
Tried re-seating the Ram, resetting everything PRAM, PMU, NVRAM and countless other suggestions that I have read.
Im kinda hoping its just a hdd and can replace that. Before I tear this thing down anyone have any suggestions? The combo drive not being recognized is throwing me for a loop.
Thanks

Sound like there is directory damage. Try DiskWarrior

The Disk Utility app that comes with the Mac OS is cannot repair that type of error. That is directory damage. You need DiskWarrior.

Hard drive not recognized during windows server 2008 setup

hard drive not recognized during windows server 2008 setup

Hi,
Whether the hard disk is recognized in BIOS?
Connect it to another computer to see if it could be recognzied incase the cause is the disk itself. Also please check if it is really a RAID instead of a single hard disk - a single disk should be recognized directly while RAID cannot be recognized until
a suitable driver is installed.
Please remember to mark the replies as answers if they help and un-mark them if they provide no help. If you have feedback for TechNet Support, contact [email protected]

Apple has release a new version of iTunes 8, in responce the issues with Vista.
1.Unistall iTunes via StartMenu\Control Panel\Programs and Features
2.Delete all previous iTunes installers.
3.Download iTunes 8 from the Apple website.
4.Makes sure you close Outlook and Explorer and all non-essential programs, as it seems to prevent the install at certain points.
5.Install iTunes 8.
6.After the Install is complete, Open iTunes 8 before attaching your iPhone.
7.Unlock your iPhone if it is lock with a pass code.
8.Attach your iPhone, after a few seconds you should see that it has installed a driver for your iphone, then the iPhone will appear in iTunes.
I hope this helps, as I did spend some time with this issue myself.

My dvd drive not recognized in device manager,getting the yellow explanation mark.

my dvd drive not recognized in device manager,getting the yellow explanation mark. Tried uninstallingdevice drive and scanning for new hardware. scanned for updates, etc. I getting no results. The laptop is a Pavilion DV5. Thanks

Hi,
It could be that the drive has a Hardware issue, but try the following.
From the Start Menu, open All Programs, open Accessories, right click the Command Prompt and select 'Run as Administrator'. In to the prompt type the following command and hit enter.
sfc /scannow ( note that there is a space between sfc and the / )
Let the process complete, then type exit and hit enter.
Next, open Device Manager, right click the DVD drive and select Uninstall. When this has completed, restart the notebook and let Windows rediscover the device and check.

Drive not recognized - new issue...help please

I am replacing a 120 GB drive with a 250 GB one to give more space for video files. On reboot, I get the message: You have inserted a drive not recognized...etc...with the choices to initialize, ignore or eject.
Then I notice that the drive on the same bus (in the bottom of the tray) is not seen on the desktop. It was in two volume partitions and was also a 250GB. Big mystery. So I remove the new one and connect just the older drive. No luck, message says ...a drive not recognized...etc. So then I change the jumpers twice - same results - and I remove the jumper...same thing. I see this drive in Disk Utility represented by a number and size (232 GB) but not by the volume names. And when I try to verify or repair, the option is greyed out (yes, I booted to the install disc and went to Disk Utility, as per instructions.
This disk has data on it I need, and it's not backed up. All I did was unplug the connectors and then replaced them as before. So please, tell me how I can restore this one. I could remove it and put it in an external FW enclosure and then see if it shows up, but I don't want to take chances. Worse case scenario is a data retrieval service - and I'm almost certain I shouldn't have to do that as this is a healthy drive.
Any suggestions very gratefully appreciated, thanks!
Keith

Tom, I tried every one of your suggestions: set the older drive (Seagate) at P4 and first connector on IDE ribbon to cable select and the new drive (Hitachi) in tray just above it at P5 - end connector on ribbon also to cable select. Result: two dialog boxes for both drive on reboot "You have inserted a device not recognized..."
Then I tried slave on the Seagate and Master on the Hitachi...same result as above.
Then I tried alternate Master and Cable Select configs. on the Hitachi for 15 or 16 pin..whatever that is...but was printed on strip on drive. No go.
I think it must be another issue here than jumpers...although that may have something to do with it. When I installed a new drive in my Quicksilver I never got the Device Not Recognized dialog...it either saw the drive with all data on it or it didn't, until I set the jumpers correctly, as directed for that incident.
What bothers me is that when I removed the new Hitachi entirely and reconnected the old Seagate as the only drive on that cable, either with jumper set to CS or M or S I am still getting the dialog.
Any other solutions, please.

USB flash drive not recognized on desktop or disk utility

I see a number of similar threads to this but nothing solves this problem. Any help will be greatly appreciated as I am about to go crazy!
I have 3 USB thumb drives that all worked 2 days ago - now only one does. I have tried all drives in multiple ports and the same result. I have restarted the iMac (2009 Yosemite) a number of times and the same result.
This came about attempting to create bootable USBs with each of these. I was struggling with the process on my mac so took 2 (brand new 16GB PNYs) to a PC created the live boot USBs and they booted fine on the PC (knowing this wouldn't boot my mac). I did however plug them into my mac and they were recognized. I finally found success creating a Ubuntu live boot with my old USB. With that success I wanted to try with one of the new USBs on the mac.
Here is what I did:
1. Using Disk Utility - Reformatted the drive 1 partition MS Dos FAT 32
2. In Terminal unmounted the drive and ran a dd command to copy the linux .img file successfully
3. Box came up saying drive not recognized and selected to ignore (this happened on my old one that still works also)
4. Ejected drive from terminal
5 Restarted mac and attempted to boot from USB without success.
After this the 2 new USBs were no longer recognized in any usb port while the other still is. They do not show on the desktop nor in Disk Utility. I checked them on the PC and they are still both recognized and showing the FAT 32 format.
Help please!

Thank you for the reply. I found some time to go through this process a number of times without success
Any other suggestions?

HT5639 after The Boot Camp for Windows 8? DVD Drive Not Recognized or Reading CD/DVD

after i made The Boot Camp Setup for running Microsoft Windows 8? DVD Drive Not Recognized or Reading CD/DVD

thanks for the response
1. Yeah I thought that's a mandatory thing because i need to be able to control the brightness with my keyboard, updated graphics card, boot camp control panel, etc
2. No there's no enable for this because Windows 8 recognizes it as a "disconnected device" and asks me to reconnect the dvd drive to the machine (which it obviously already is).
3. Ive tried those before, also even editing the registry but it didnt work.
It's weird because it never happened before on Snow Leopard » Lion bootcamp driver updates. Just in Mountain Lion

CD stuck in combo drive – not mounted / not recognized, so cannot eject

A CD which had been recognized and could be played in iTunes was in the combo drive when I rebooted. After reboot the CD was not recognized/mounted, and was not visible in Finder, iTunes, or DiskUtility (therefore, it cannot be ejected).
I rebooted with the mouse button held down but nothing happened. Then I did drutil eject, trying it a few times in succession, but nothing happened.
At no time after the original reboot has there been the slightest clicking or whirring noise from the combo drive. Evidently the system 'thinks' the combo drive has no disk inside it.
I haven't tried to go into single-user mode to try to eject it from there. (Incidentally, I have conflicting methods on how to enter single-user mode – is it cmd-s or cmd-opt-o-f ?) Before I try that, my question is that given that I know a good CD is inside the combo drive, is there any command (in Terminal) that would make the system force it to mount?
Thanks for any info.

New Pioneer DVD drive not recognized in profiler

I have used these forums many times to solve my problems so a big thanks to everyone who contributes. I've never had to actually ask a specific questions until now so here goes....
I have an e-mac running 10.3.9. My superdrive started to get flakey (not recognizing some DVD's, spitting them out, etc.). I followed all the advice here but no luck so I finally replaced the original drive with a Pioneer DVR-118. My problems still exist and the system profiler is telling me I have a Pioneer DVR-106. Did I do something wrong on the install? Shouldn't the profiler recognize the new drive?
A big thank you to anyone who can help me through this.

Since your computer's Apple Hardware Test is on a disc and the built-in optical
drive won't work, you may have to see if an external optical drive capable of
being used as a boot, is available. This of course would be a FireWire combo
type drive that can read & write DVD & CD media and boot Macs.
You may have to see if you can archive anything worth saving from that eMac
and put it on media via another computer; if the eMac can be booted into
Target Disk Mode where it is seen by another computer as a FireWire drive.
In fact, you could see (in a reverse scenario, perhaps?) if another computer's
optical drive could be used by your eMac, if a second healthy computer is
available & then boot it into FireWire Target Disk Mode to see if you can use
the optical drive in there as though it were a peripheral. - This may not work.
I've not had to really use FireWire Target Disk Mode, but do have cables,
and an externally enclosed LaCie FW HDD which is partitioned for clones.
There are times where a FireWire externally enclosed superdrive is handy.
There may be some damage on the logic board or some circuit that does the
controlling of ATA devices on one of the buses in the computer. That would
be a possible cause of the issue. If the identity of this drive can be changed
by the user before it is installed, be sure that is set correctly for use in eMacs.
{The three eMacs I've owned, had issues early on and I got rid of them in mere
days of first purchase; at considerable distance and effort by me. Then I got
an iMac which was an unholy terror to debug after an 'authorized service' ctr
did their best to kill logic boards and sell me defective store-brand RAM they
were authorized to install in a place I was not. ThreeThousand Miles and Six
Months later, I finally got my iMac back, repaired. Only because Apple told
them to read my test notes - & just install the parts I said it originally needed.}
Do you have a second Mac nearby (presuming yes, and using it online) which
may be used to attempta further diagnostic or testing of the eMac?
Not sure if an Apple Hardware Test would be sufficient to tell the issues in
your computer; if you have a way to make use of it via external FW. Hope-
fully someone with more extensive eMac and drive experience will advise.
Good luck & happy computing!

External hard drive not recognized... help please.

okay, well here is the story:
my iBook G4 had its stock 30gb hard drive in it and it was running extremely low on space. so i figured i didn't want to carry around an external hard drive, therefore i would buy an internal hard drive an install it. so i purchased a new 2.5" 80gb hard drive and called up the local apple store. they told me that although it was under warranty, that it did not cover hard drive installation. so i looked it up online and found step by step instructions to install the hard drive. so after lots of hard work and many screws, i installed the new hard drive successfully... but i still had this perfect 30gb hard drive. i thought maybe to save a few bucks i could turn it into a usb external hard drive. i found an enclosure for the hard drive and a usb 2.0 cable and plugged it into my ibook. it was recognized and everything. i put some files on the external hard drive and transferred it to another mac. this is where the trouble started. i plugged the hard drive into a PowerMac G4, and it was not recognized... so i tried it on a different mac. this time on a PowerBook G4, but no luck. this issue has been troubling me for a few weeks. but then i tried it on a similar iBook G4... and it was recognized. but i don't know why it was only recognized only on the iBook G4 (not the same iBook G4 it was pulled out of) and no other macs.
does anybody have any ideas what we can do to get this hard drive to be recognized by other macs?
any of even the smallest ideas would be greatly appreciated.
thanks,
tyler
iBook G4 Mac OS X (10.4.3)

I can walk you through formatting the hard drive:
1. Hook it up to an iBook that recognizes it.
2. Go into your Applications folder, then scroll down to Utilities. Open Utilities and scroll down a bit and you should see Disk Utility. Double-click.
3. On the left side you should see your internal hard drive and your external one. Each hard drive will have a sub-catagory with the partition indented.
4. Your external hard drive will probably be the second catagory. Click it.
5. In the center-top you should see the tabs First Aid, Erase, Partition, RAID, and Restore. Click the Erase tab.
6. You should see Volume Format: and then a drop down menu, and Name: and a text box. Type in the name you want the external hard drive to be named.
7. In the drop down menu, select Mac OS Extended (Journaled).
8. Then, simply click Erase, watch the progress and it should be good to go!!
Hope I helped you out. Oh, and it might be the enclosure...and also what OS's? Since it's USB it is probably using a USB Mass Storage driver. Mac-wise, if formatting doesn't help, I would get a FireWire enclosure because FireWire is much faster than just USB 2.0. Oh, thats nother thing...Is the enclosure Hi-Speed USB? If it isn't, I would definitely get a FireWire one...If it is, the PowerMac G4 doesn't have Hi-Speed so you're not taking full advantage..Just some insight

Primary slave drive not recognized

Here is my setup:
MSI 865 Neo2 motherboard
WD 80GB SATA hard drive (primary master)
Maxtor 3400 11.5GB hard drive (want it to be the primary slave)
DVD/CD-RW combo drive (secondary master)
Zip Drive (secondary slave)
The WD SATA hard drive is hooked up to SATA1. The secondary drives are hooked up to IDE2. The Maxtor drive is the only thing not working correctly, and is currently hooked up to IDE1.
- I've tried no jumpers to set the drive as slave
- I've tried the cable select jumper with the slave position on the IDE cable
- The drive isn't recognized in Windows or BIOS
- When hooked up to IDE2, it's recognized (so I know the drive CAN function)
- I have successfully(?) messed with BIOS to the point where the drive is recognized by Windows, but then my DVD/Zip drives become the 4th master and slave
I think that it's a BIOS setting thing, but I don't know enough about BIOS to get it to work properly.
Thanks.

This will probably be fixed with a reformat. The computer does not recognize this hard drive as the boot-to hard drive. Somehow either the MBR became corrupt or you just need to go old school with your cabling system.

Let me just say that NO JUMPERS means cable select....
Have you ever tried putting the devices in the correct positions on the cables? Although this is an older solution, you are using a legacy method anyway.
First position: Master
Second position: Slave

Macbook Leopard Update- Hard drive not recognized?!?!

Question- What do you think caused this problem, and how can I best fix it?
(See below for information)
Well, I finally decided to update to Leopard. I put the disk in my Macbook, and everything went smoothly as it verified the installation DVD- until the end of the verification, that is. A message screen would pop up telling me the disk was dirty. "Okay," I thought,"No problem." I was a bit puzzled, though, because the installation with the same Family Pack disk went fine on my father's Mac. I cleaned the disk, and tried again. And again. Each time, I was greeted with the same message at the end of the verification. Frustrated, I took the disk and my laptop to Best Buy, hoping someone could help me there. We ran the installation again... to no surprise, the same problem occurs. This time, though, when we quit the installer and try to reboot, after the gray screen with the apple at the beginning, we are greeted with a black screen with one command line. NOT GOOD! We rebooted the computer again, this time starting up with a disk to check the permissions and hard drive. The diagnosis: The permissions on my Mac are screwed up, so it's not recognizing the hard drive. The Best Buy guy claims the permissions have been messed up since I bought the Mac, and everything will be just fine and dandy after I transfer the data to another computer, install the Tiger disk that my Macbook came with, update to Leopard, then transfer the data back to my Mac. I'm taking my Mac to the closest Apple store (about 2 hours away) for advice from the pros on Saturday. Until then, I'm hesitant to even turn the thing on, out of fear it will spontaneously erase the data or something to that extent.
Question: (in case you forgot)What do you think caused this problem, and how can I best fix it?

Unplugging worked!!!
I have no idea what PRAM is but someone said that unplugging your computer resets it so, I thought I'd give unplugging a shot. So, I shut down my computer and unplugged it. I also unplugged the power on the HD. (because I wasn't sure which one they were talking about.)
Anyway, I went away for about five minutes.
I came back plugged in the HD power first. Then, I plugged in the power cord for the computer and turned it on.
As soon as I logged in I was asked if I wanted to use my external HD for Time Machine backups.
I saw the icon for the HD on the Desktop where is belongs. I can open the drive and access the files with no problem.
Try this if you haven't yet.

IMac G5 Internal Hard Drive Not Recognized

I shut down my iMac G5 with the power button and not through the typical shutdown procedure once and then when it booted up it would not get past the gray screen. I eventually used the Leopard DVD to try to boot it and was able to get to disk utility to look at the drive. I tried to repair the drive but then the machine froze and I had to restart once more. Now the internal hard drive isn't recognized or seen at all. I actually switched out the SATA hard drive with another spare I had and that was not recognized either. I can get the mac to recognize the installation DVD still so I know my computer still functions properly but I just need it to recognize the drive now. Does anyone have any ideas how to resolve this?

Have you access to DiskWarrior or TechToolPro? Either of those might fix your problem otherwise, try booting from the Apple Hardware Test on your install disc and see what it says.

Hard crash now hard drive not recognized in disk utility.

During a virus scan the Macbook froze up now the computer does not seem to be accessing the hard drive. Tried to reinstall Leopard but the internal hard drive is not recognized (same is true when we tried to use Disk Utility). It will not start in safe mode either. Does this sound like a fried hard drive or maybe a corrupted drive that might be repairable with DiskWarrior? Any thoughts would be appreciated.

If the A/V you were using was Norton/Symantec, the drive may be OK. Norton is a virus.
Burn a Ununtu CD and see if you can boot into it and look at the drive before giving up on it.
