Discs not mounting

so this is wierd, has anyone had this happen? i am going through my cd collection and copying them to my external HD using itunes. i have noticed that about 50% of the time i put in a CD and itunes reads it and asks if i want to add it to my library. i click yes and POOF it disappears. no longer showing in itunes or on the desktop. i then go into disc utilities and mount it - once again itunes asks if i want to add it, i click yes and no further problems. i have cleaned my superdrive using a commercial lens cleaner disc. any ideas?

Yes this is happening to me too! It is getting somewhat annoying as there doesn't appear to be any pattern associated with it happening. Keen to have an answer on this one.

10.5.5 update Startup disc not mount to desktop

Since updating to 10.5.5 my startup disc (Main) does not mount on desktop or appear in finder.
Disc utility says all is normal. In fact the volume appears in sysprefs as startup volume.
I tried deleting com.apple.finder plist to no avail.
Automatic login is disabled.
Any other suggestions?
What about DiskWarrior or other utilities?
TIA, John

check finder preferences general and sidebar. make sure that hard drives are set to show up in the sidebar and on the desktop. if that doesn't help, it might be the invisibility bug. check out this link

Tiger install discs not mounting

Hi folks,
My girlfriends G4 Powerbook (867mhz) has been playing up, sluggish,kernal panics etc.
The usual maintenance/troubleshooting has made little difference.
I suggested she re-install Tiger, however her Tiger discs won`t mount (other discs are fine).
Q: Can I use the install disc that came with my G5dual 2.7 ?
Cheers

I'm assuming you're trying to use machine specific disks (gray in color) with the G4. Apple changed how the bundled disks are made starting with Tiger. The disks check to see if the hardware matches the Mac they came with. If not, they won't work.
In order to install Tiger on her G4, you'll have to purchase a retail, commercial copy of Tiger.

USB hard disc not mounting.

I've just got a new USB 2 hard drive (20GB Smartdisk Fotochute FAT32 formatted)) but I can't get it to mount on my iMac (C2D 24") in OS X (10.4.10).
The drive works fine on my iBook G3 (700mhz 10.4.9) and also on the iMac in bootcamp, it appears in system profiler but not in Disk Utility. The oddest thing of all is that it works fine when connected via the USB port on the keyboard. I've tried connecting through my belkin hub and directly to all 3 ports on the iMac with and without the drives external power connected.
I have 2 other USB hard drives that connect just fine (one FAT32 and one HFS+ formatted).
Any ideas what might be stopping the drive from mounting?
24" iMac Mac OS X (10.4.10)

Hi FonzCam
Shut down and disconnect all USB devices (including hubs and extension cables) except for your Apple keyboard and mouse. Restart, then connect your External HD directly to your computer. If your External HD now mounts and works properly, there is a conflict between that device and one of your other USB devices or hub. There maybe another device (iPod, jump drive, scanner, etc...) already mounted on the (USB string or chain) causing a conflict.

Z400 Discs with EFI partition not mounting after Win 7 Pro upgrade

HP z400: After a repair/upgrade of Win 7 Pro (64) sp1, any external disc with an EFI partition will not mount. Drive will be present in BIOS and Disc Management, though without a letter. Unable to assign a drive letter. All other discs mount correctly. Drives with EFI partition will mount on other PCs. All drivers appear to be current and fuctional.
This question was solved.
View Solution.

I figured it out... after two weeks of head-scratching, I finally found the cause.
I run MacDrive 8 so i can read discs with HFS+ formatting. That program needed to be fully uninstalled and re-installed after the upgrade. I had de-activated it prior to the upgrade, but it needed more than that. Everything works now as expected.
But wouldn't it be ince if Windows would read mac discs natively?

Install disc will not mount

I was hoping to use Disc Utility on the install disc that came with my MacBook, but it refuses to mount! My MacBook will read the Applications disc it came with as well as any other DVD I put in. However, it will not mount my install disc or my wife's white MacBook install disc. For whatever reason, it makes some noise and spits it right back out. I tested both discs on my wife's computer and they mount just fine.
Why would my MacBook refuse to mount any install disc but continue to mount all other discs? I tested both single and DL discs.
I should also point out that my drive was just replaced under AppleCare. I am not sure if this was a problem before because I never needed to use the install disc until now.

Since this is a hardware problem you just had fixed, I suggest you take the computer back for more service.

Inserted disc sometimes does not mount

Hello -
Just picked up a new i5 iMac over the weekend. Going through the process of reinstalling my software.
Occasionally when I insert an installer disc into the drive, it does not mount, and I am unable to eject it. If I launch Disk Utility it does force the drive to start spinning and it recognizes the disc. This doesn't happen every time, and it's not always the same disc that causes the problem. Seems that the drive intermittently does not start spinning when I insert a disc.
I do plan on calling Apple if I cannot fix the problem myself.
Any suggestions that may fix this?

Very simple solution - take it back and ask for a replacement computer. if you read thru the posts you will see there are thousands of people with the same problem. Apple has not come up with a cure yet.

Trying to use Disc Utility to copy a disc. What is "unattached disc file" and status "not mounted"

Trying to copy video disc. Messages are "unattached disc" and status "not mounted". The disc has been recognized by Disc Utility.

You do not need to run the setup disk...you can configure your router manually.

Lacie d2 DVD+RW not mounting discs

Alright, I have a Lacie d2 DVD+RW burner. I bought it in november and it has worked perfectly since buying it.
Today I attempted to burn my first dual layer DVD, I author it in DSP 4 and then burn it using Toast 7.
So I attempted to do my first dual layer DVD burn when i was bombarded with errors from toast. Unfortunatly I cant remember what they were.
So I went and checked the file in DSP and noticed i did not switch the disc preferences to dual layer, so i fixed that and did a build again.
I went to do a burn using toast inserted my DVD and it did not reconize them as blanks.
So i did a reboot and tried inserting a blank DVD and it did not mount it, I tried putting in a normal DVD and it did not mount, I tried a CD, same thing.
So I tried a bunch of troubleshooting and nothing worked, installed all the latest firmware and still nothing. I've switched cables and still nothing.
The system profiler at work where this was going on, said everything was there and working, that is using PowerMac G5, 10.3.9
I've since taken the burner home and tried and still nothing works, at home im using iBook (10.4.8).
The system profiler at home says this,
TSSTcorp CD/DVDW SH-W162L:
Firmware Revision: LC03
Interconnect: FireWire
Burn Support: Yes (Unsupported)
Profile Path: None
Cache: 2048 KB
Reads DVD: Yes
CD-Write: -R, -RW

Burn Underrun Protection CD: Yes
Burn Underrun Protection DVD: Yes
Write Strategies: CD-TAO, CD-SAO, CD-Raw, DVD-DAO
Media: No
Can anyone PLEASE HELP ME!
I need the burner, because the burner on my PowerMac G5 already died.

I am currently awaiting a email from Lacie to see what they think.
I am trying to see if this is a tower problem, Lacie problem, and if it was caused by the disc which I originally tried to burn (a Verbatium DVD+R DL).
I can still control the drive, making it eject, its just not even trying to read the discs.

Drives are not mounting to desktop on macbook pro.

External USB drives, SD cards and even DVD media is not mounting to desktop when connected.
This is a new problem for me and have not had this issue previously. I have successfully connected the same devices in the past.
They all show up in the disc utility as connected. I am unable to mount them from disc utility (this button is disabled) and they are not showing up in Finder either.
Please help!

Hi Paul,
Sorry for the late answer. I live in Europe, so that's why I was asleep ;-)
Basically the command tells your computer to unhide everything on your Desktop, so if you don't have a Desktop, something is definitely wrong.
My guess is that there's something wrong with your account on that computer. You can check that by creating a new account in System Preferences (click on Accounts, click the lock in the bottom-left corner and then click the "+" button just above).
Then try mounting "some" media and see if it appears on the new user's Desktop. If not, I would highly recommend to reinstall Mac OS X.
HTH,
Jasper.

Internal Hard Drive will not mount -- need help!

My Mac Dual 450 has been a constant problem since I installed Tiger several weeks ago. There have been crashes every day. Disk First Aid did not help. Then I discovered I had TechTool Deluxe which I had gotten from Apple a few months ago. It has diagnostics for just about everything you can think of. I tried it. Big mistake.
Everything came out OK except it said there were some bad blocks, and an invalid BTree node size 8.0 (whatever that is). I tried to get it to repair the HD and it said it could not, that the HD was not mounted (I had booted from TechTool disk). Then I tried to reboot from the internal HD and I got a big bad black box saying that I had to restart. I tried that many times and kept getting the message. I booted from the Apple Tiger install disk and tried to run Disk First Aid on my HD but it said there were problems and Disk First Aid could not correct them because the HD was not mounted. I tried this and the TechTools Disk many times. Same result.
I then booted from an external system 9.2.2 HD and tried to use the Disk First Aid on that. Same result: it said the Macintosh HD (my internal) was not mounted so Disk First Aid could not repair it.
I have tried everything I could think of (option-boot, C-boot, etc) and nothing will let me boot from the internal HD or even mount it. I spent quite a bit of time with AppleCare rep and he could not succeed in getting the HD to mount.
He suggested either trying Disc Warrior which I do not have, or possibly resetting the PMU on the logic board and he sent me instructions for that, which seem ominous to say the least. And I doubt that it would solve my problem since the computer sees the HD, it just can't mount it. Resetting the PMU seems to be for computers that can't see the HD and won't start. But mine does just fine with other start-up disks.
Are there any suggestions on what else I can try? Is there a program that can be downloaded that mounts hard drives?
My Mac Dual 450 has 1.25 gb of RAM.
Thanks for any help. I need it fast.

Thank you for your suggestions and your continuing interest in trying to solve my problem. I rebooted with CMD + S and got the black screen with white text. Unfortunately I could not type anything on it. I typed /sbin/fsck -y and hit return. Nothing showed on the screen. I waited awhile in case this was one of those situations where it is hidden. But nothing happened. I tried the whole sequence a couple more times and same thing: I was unable to type anything that would show up on the screen.
Am I missing something here? I tried typing holding down various keys and could not get anything to register.
For what it is worth, the last line that showed on the screen is "panic. We are hanging here..."
I do not think that is related to what I typed since it was there when the screen first appeared, but could it nonetheless have somethng to do with my computer or hard drive?
I am right now installing system X.4 onto an external HD. If I can get that to boot and work OK, I can just use that for awhile until I get the internal either replaced or repaired.
If you see my previous posts, I had a devil of a time installing system X.4 to begin with. Maybe my HD was troubled all this time??? Or could there be some other underlying problem with my Dual 450? I suppose I will find out when I try to boot from the external.
Incidentally, I have an external HD with 9.2.2 on it and have had no trouble booting from it or using it.
Thanks again for your help.

CD/DVDs Not Mounting But Drive is Recognized / SCSI Card Not Seen

Apologies for this mess in advance, but I thought it was worth seeing if anyone had an idea of what to try on either of these two issues from a system software perspective before I start breaking the computer apart and tinkering with hardware.
My G4 is the 733 MHz model which first shipped with the SuperDrive. That SuperDrive died years ago and I replaced it with an HP DVD Writer 300n which worked fine up until some version update of 10.4 though I can't recall the specific version. In any case, now the drive will not mount any CD or DVD that I insert, commercially-pressed or otherwise. The eject key on the keyboard functions properly, the tray opens and closes without problem and when a disc is inserted the activity light goes on and the disc spins for a minute and all seems normal, but the disc never appears on the desktop nor in any Finder window. The drive is still recognized in the System Profiler and I've double-checked the CD/DVD settings under System Preferences to verify that nothing is set to ignore there. I suppose it's possible the laser suddenly went bad, but as I said, the symptoms showed up following an update (though it was a while ago and at the time I had no need for a optical drive on this computer so I didn't address it then).
The second issue I discovered when I attached an external optical drive via the SCSI port I hadn't used in many years. That drive wasn't recognized at all and when I looked in the System Profiler the SCSI card isn't listed under PCI Cards. Is there a generic SCSI card driver I might be missing under OS X or will I need to open up the computer and determine which card I actually have in there?
Any suggestions would be appreciated and hopefully I've provided enough information to make that possible.

Hi K Roth, and a warm welcome to the forums!
I find Optical drives fairly short lived myself, but on the Internal, you might try PatchBurn...
http://www.patchburn.de/
Do you have another Mac with Firewire and a good optical drive?
If so you can boot the Other Mac into Target mode...

Boot this G4 with the Option key held down, see if the Install Disc in the other Mac shows up as a boot choice.

External drive will not mount to desktop

Ok so i just bought a new hard drive and hooked everything up to my imac. However, it will not mount to my desktop.
1. I opened disc utility and i can see that my newly purchased hard drive is listed on the LHS with 931 GB available.
2. I click on the mount button on the top and i get this message- "The disk “disk1s1” could not be mounted. Try running First Aid on the disk and then retry mounting."
3. So now i click on First Aid and attempt to repair disc, however I get this message-"Disk Utility stopped repairing “disk1s1” because the following error was encountered: Filesystem verify or repair failed."
Does anyone have any idea how to fix this problem?
Thanks in advance.

how did that solve the issue? my 350gb seagate drive just started behaving the same way as your initial post -- it shows in Disk Utility but will not mount -- even after running disk repair/verify. This just started happening two days ago...

External backup drive will not mount on new mac mini. still works fine on the old one. new one is running mavericks

I just bought new-to-me mac mini running OSX mavericks.
Trying to migrate from old mac mini using simpletech external hard drive.
It still mounts on my old mac mini (system 10.5) but will not mount or show up when I plug it in to the new mac mini running mavericks.
Any ideas?

What exactly shows in System Profiler>Hardware>USB for those drives?
Boot from the Install Disc & see if they show up, not grayed out in Disk Utility.
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
We were thinking along the same lines. While at home I dug up a firewire enclosure and put a bootable GUID formatted drive in it (that I had in one of the usb enclosures) and started her computer holding down the option key and then chose to boot from the external firewire. All usb drives are now mounting upon connection. I asume that her drive has bad sectors on it (even though the SMART status says it's OK) and is not loading all the drivers properly for USB to mount. I was suspicious from the beginning that the OS was corrupt when she first had me look at it. It was at that point that I booted it in target mode, connected to my Macbook Pro, and then CCC'd to a usb drive that I had. I then had a couple of difficulties installing the new OS. Should have known......
I am now going to put a new drive in it for her and she'll be up and running.
Thanks so much for your help and thoughts that got me thinking as well.
