Disks Not Automatically Mounting

Since a few weeks ago, my disks haven't been mounting automatically. If I plug in a flash drive, it doesn't show up on my desktop - I have to go to Disk Utility and manually mount it. The same applies for DVD's, hard drives, etc. How do I get my drives to go back to mounting automatically?

This is my last tip. Run Terminal, and paste within this command:
sudo defaults write /Library/Preferences/SystemConfiguration/autodiskmount AutomountDisksWithoutUserLogin -bool true
then, press Enter.
See if this work.

Time Machine Backups disk not automatically unmounting after backup completes in Lion

I am using Time Machine over WiFi on a 3rd party USB drive shared as an AirDisk through an Airport Extreme router. Ever since switching to Lion (clean install), I have noticed that the Time Machine backup disk will not automatically unmount after a backup is completed. This creates a problem when my MacBook Pro comes back from sleep. Specifically, the WiFi notification icon in the Finder toolbar indicates that WiFi is connected, even though it's not connected to a network, and I am unable to connect to any networks for what seems like several minutes until the Time Machine backups disk disappears from the desktop and WiFi actually connects.
Since the disk was not cleanly unmounted, Time Machine then keeps complaining that the sparse bundle file is locked and cannot be mounted every time it tries to do a backup. I have to either disconnect/reconnect the USB drive physically from the router, or restart the router every time this happens to resolve the issue. That is getting really annoying to have to do every time. I suppose I could manually unmount the Time Machine disk after every backup but it's ridiculous to have to do that every time I want to put the computer to sleep.
Is anyone else experiencing this issue and is there a fix?

For others who might be having this problem - I was able to resolve it by connecting my backup disk to my mac via USB, completely erasing it, and starting over from a new backup. Disk Utility was not reporting any errors when I verified the disk, but I went ahead and repartitioned it and started fresh. The disk now automatically unmounts after backups complete.

Arch 2.6.36 not automatically mounting USB devices

Hi,
I am new to Arch but up to now i really like it and i am using this for my home server.
Now i use 2 external USB 1TB disks for backup which i auto mount using /etc/fstab.
The problem is that it is not auto mounting the volumes.

It seems to recognize the physical disks but a mount is not performed?
Did i overlook something or is there something else wrong?

/etc/fstab is for FS options only, putting you device there does not guarantee automounting. This has already been discussed: https://bbs.archlinux.org/viewtopic.php?id=48469

Disks not un-mounting from desktop

I have downloaded a few programs, and the disks won't unmount or eject. I get the trash can turning into an eject icon, drag it to the icon, but nothing happens.
Anyone else experiencing this?

Yes.
Its very annoying. After a restart I was able to eject some for a while, but within a short time the problem returned.
I have found that you can eject them through disk utility.

Partitions on internal disk not always auto-mounting

I have a 24" 2·93GHz Imac running 10.5.8 with the internal hard disc split into five partitions: one for OS X, one for documents, one for first line backup of my email, one as a scratch area and one for Windows under Parallels. Occasionally, the documents and Windows partitions don't automatically mount at start-up. I can mount them in Disk Utility quite happily, and Disk Utility reports the hard drive SMART status as "Verified". Does anyone know why this is happening? Should I be (more) worried?

Was there a time when all five partitions mounted with each startup and then they quit doing so, or has this undesired behavior been present from when you initially created the five partitions?
I've never had a partitioned internal drive but I do use partitions on my external Firewire drive. Maybe someone else can comment but I wonder if the startup drive "likes" to have several partitions on it or not?

Steve M.

Disk Image won't automatically mount for Share iPhoto Library

Hey All,
I've just got a new mac and am sharing an iPhoto library between two users. I moved the iPhoto Library Folder to a DMG set it to ignore permissions.
In each account I did the following: Hold down the option (or alt) key and launch iPhoto. From the resulting dialogue, select 'Choose Library' and navigate to the new library location. From that point on, this will be the default library location. Both accounts will have full access to the library, in fact, both accounts will 'own' it.
The problem is that the DMG won't mount automatically mount. I set it up under both user accounts to mount at start up but it won't do it.
Am I doing something wrong?

Are you using fast user switching or logging out and then back in to the second account? It may be that fast user switching doesn't trigger a "startup" scenario in the second account which is necessary for the disk image to mount.
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier) database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger or later), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 6 and 7 libraries and Tiger and Leopard. Just put the application in the Dock and click on it whenever you want to backup the dB file. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
Note: There's now an Automator backup application for iPhoto 5 that will work with Tiger or Leopard.

Trying to automatically mount two disk images from NAS

I am trying to get two mac os x journaled sparse disk images to automatically mount upon login. I have tried to add the following items to my login items under System Prefs/Accounts and none of them have worked:
1. Browse to the file and choose it
2. Create an alias and choose the alias
3. Mount the disk, and then browse to the mounted disk and choose it
4. Create a symbolic link and then choose it
Maybe I am doing something wrong, and maybe there is a different way to do it. Any ideas?

V.K. wrote:
I don't know what's going on here. as i said it works for me.
try doing it using a terminal command.
make a new workflow consisting of a single action "run shell script".
inside the shell script put the following
hdiutil attach /path/to/diskimage
to get the path to the image drag it to the action window. enclose the path in quotation marks. it should look something like this:
hdiutil attach "/volumes/dlinkroot/Volume_1/media/photos/iPhoto/imagename.sparseimage"
If you want the image to mount a bit faster add -noverify to the command like this:
hdiutil attach "/volumes/dlinkroot/Volume_1/media/photos/iPhoto/imagename.sparseimage" -noverify
see if it mounts this way.
Thanks for the quick feedback.
That shell script option almost works. What I noticed was that /Volumes/Volume_1 which is the volume created on the dlink NAS needs to be mounted in order for the sparse images on the NAS to be mounted. Maybe the other way also I had the same issue (login items as well as automator app). It's just that I noticed it only now.
So is there a way to ensure Volume_1 is always mounted? Adding hdiutil attach /Volumes/Volume_1 does not mount it

LaCie 1TB Big Disk not mounting as a shared device

Hi!
Today, I purchased a brand new AirPort Extreme 802.11n to replace my now dead NetGear WGR614. The set-up went well, but I have a query.
I also own a LaCie 1TB Big Disk connected to the AEBS via ethernet as a NAS Drive. The disk itself is set-up with Apple File Server and Bonjour Services enabled. With my NetGear WGR614, the hard drive would automatically appear in the Shared Devices column in Finder. The only way I have been able to achieve this same outcome is to log into the drive using Command-K and then adding it to the Login Items in the Accounts Preference Pane. This is so it will automatically appear connected in the Shared Devices column after a restart.
I have spent the morning searching many and varied forums for a solution, but almost all entries deal with USB connected drives.
If anyone has some information they would like to share, it would be greatly appreciated.
Many thanks in advance.
Rodger.

Is there a way to prevent a Windows Logical Disk Manager volume from being automatically mounted?

Lion is automatically mounting two LDM partitions from BootCamp, doesn't find a valid filesystem, and then asks to format or eject them, every time that the system boots.
How do I go about preventing these disks from being automounted?
They don't display UDID's, so I'm unsure if I can hide them using fstab, unless fstab supports the old disk-based specification that it used to.

Although the little camera I was using doesn't capture 16 bit, I did run the jpgs briefly through ACR to try out the shadows/highlight feature since the photos were perfect candidates. My preference there is to convert to 16 bit ProPhoto so maybe--even though the files opened as jpgs. That might be the problem: maybe bit depth is the trigger for psd assignment. Still, I wish there was a way to disable it.

Powermac g5 will not boot---hard disk appears not to mount

tried resetting smu, nvram
tried disk util---does not see drive(orig. 160 gb)
tried new disk---not recognized either
boots to OF ok
i'm running out of patience and have no money to take it to apple
would greatly appreciate any input/advice--thanks

Dear Fryan,
Welcome to Apple Discussions.
The HDD is not mounting and there could be lot of reasons for this malfunction.
What you can try is :
1.Open the unit and reseat the HDD cable.
2.Re-pair the RAM .(re-arrange)
3.Do PMU/SMU reset.
4.Try to boot holding the "option" key. You will see the HDD icon if you do not see the HDD icon that means the boot rom is failing to rcognize your HDD. This could be a Logic Board faliure or a HDD faliure (but lets not assume things so fast
If you do see the HDD icon then click on it and then click on the right arrow.
5.If the previous step fail try to boot to the install disk holding the c key or the same procedure usin option key.
6.If it is able to boot to install disk thank god that your logic board is safe.
7.Your install disk has an Apple Hardware Test included you will have to boot it holding the option key and choose AHT to boot to AHT and run the test.
(Addtional testing steps)
1.IF you happen to have another MAc then you can connect the affectd Mac to a known good Mac via firewire cable and boot the affected mac with the HDD of the good MAc by holding the option key and starting the good mac with T key.
Also you can do the reverse step to chekc the HDD of the Affected mac.This procedure is called target disk mode.
Tell me how far you are able to go.
Hopw this helps.
Good Day!

Time Machine / Time Capsule Error: Backup disk image could not be mounted

So I'm trying to back up to time machine, which used to be working fine, but I have this problem happening on two computers now (which probably means the error is in my Time Capsule.)
The Time Capsule shows up on my "shared" list in my finder windows.
I can connect to it, and open the folder inside, and SEE my two disk image files in there.
But Time Machine gives me a "The Backup Disk Image Could Not Be Mounted" error. No other information.
If I double-click on the disk image file directly, I get an error "The Following disk images failed to mount" and then it lists the file and says "Resource temporarily unavailable."
Help, please.

I'm caught in the same loop, with no end in sight. I've only been using Time Machine and Time Capsule for 2 months. This week it stopped working. First error message:
"Unable to complete backup. An error occurred while copying files to the backup volume."
Checking the Time Machine preferences, "Last backup" would read "backup failed"
When I got this error, all the wireless functions went offline, even thought the TC light was still green.
I would shut down, shut down the Time Capsule, shut off my modem reboot everything in order.
Next error message:
"Disk repair. The disk 'Backup of [my computer]' was not repairable by this computer. It is being made available to you with limited functionality. You must backup your data and reformat the drive."
Then: "Time Machine Error: The backup volume is read only. To select a different volume ... Time Machine preferences ... "
I spoke to someone at Apple, who sent me the Time Machine Troubleshooting page:
http://support.apple.com/kb/HT3275?viewlocale=en_US
I went through:
1. updated my system software
2. updated the TC firmware to 7.4.1
3. dragged the sparsebundle to DiskUtility. It took a while (more than an hour?) but said the disk could not be repaired. When I tried again, the repair function wouldn't run.
4. tried to delete the sparsebundle, but it would choke at almost the end, sometimes it would just crash the finder, sometimes say "Sorry, an unexpected error occurred," sometimes "Operation cannot be completed because the item 'bands' is in use." I even tried to Stuff the bundle with 'delete original' checked, but the stuffing, after about 15 hours, jammed near the end (stuffed 20 gigs of 35 gigs).
5. tried to reselect the TC, and run backup anyways ... now it can't find the volume, back to the error messages and crashing Finder
6. checked password in Keychain, all ok.
Now what??
Do I use Airport Utility to erase it? At least TC is still showing up there. Or press the rest button on the back of the Time Capsule to reset to factory defaults?
I've resigned myself to losing my backups. Now I would just like to get it up and running again.
In hopes,
Linda

Startup disk "Not mounted", needs to be repaired but can't get it to mount

I did a Verify Disk because my HD has been having issues. It told me I needed to backup and reformat, so I went ahead and backed everything up and went to DU in recovery mode.
But when I got there, my Macintosh HD showed up as "Mount Point: Not Mounted", so I did the following:
I clicked on the Macintosh HD from the list and clicked "Mount". It gives me the following:
Mount failed
The disk "Macintosh HD" could not be mounted.
Try running First Aid on the disk and then try mounting.
So I click "Verify Disk" and it gives me this:
Disk Utility stopped verifying "Macintosh HD"
This disk needs to be repaired. Click Repair Disk.
So I go to click Repair Disk but it's grey and cannot be selected, I assume because my drive is not mounted.
So how can I'm in a paradox and REALLY need help with getting my startup drive mounted again. Can anyone help?
Let me know if I can provide more info for troubleshooting and thank you in advance!

Install or Reinstall Mavericks or Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
OS X Mavericks- Erase and reinstall OS X
OS X Mountain Lion- Erase and reinstall OS X
OS X Lion- Erase and reinstall Mac OS X
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.

Time machine - "the backup disk image could not be mounted"

SInce a few days, I am unable to backup via Time Machine.
I always get the message:
TIME MACHINE ERROR
The backup disk image could not be mounted
I use an Apple Time Capsule and still have more than enough free space on it.
Use OS X 10.5.5
Help.....
Tks

Rosy,
*_"The Backup Disk Image Could Not Be Mounted" (Console - “Failed to mount disk image”)_*
First, it is important to distinguish this error message from another, similar Time Machine error that states “The backup volume could not be mounted”. This is important as the causes and cures for these two errors can be very different.
Consider each topic below separately. When one option does not resolve your issue, then move on the next one.
*Unmount the Backup Disk Image* (TC)
If, for some reason, you have manually mounted the Time Machine backup disk image (sparsebundle), or Time Machine failed to eject it after the previous backup, subsequent backups may fail. (Console - “Failed to mount disk image”… “Backup failed with error: 21”)
Eject the backup disk image (white drive icon) by either clicking the little Eject icon to the right of the disk image in the Finders’ Sidebar, or Ctrl-Click the drive icon on the desktop and select “Eject” from the contextual menu. Now try backing up again or launching Time Machine to view previous backups.
*“Disconnect All Users…”:*
If your Time Machine backup drive (“Backup of Users Computer”) is mounted on your desktop or in the Sidebar of the Finder window. then Time Machine may think the drive is already in use. Alternatively, if the Time Capsule hard disk has been recently accessed by a Windows machine, it may not have fully relinquished control. Do the following:
Open Airport Utility and select the Time Capsule on the left.
Click “Manual Setup”.
Select “Disks” at top of window.
Click “Disconnect All Users…” at bottom of window.
Close the Airport Utility.
Now try Backing up again.
“I got it resolved. Apparently it had to do with one of the files being open on the disk from the drive. I had browsed the disk with one of my windows boxes here and it must have left one of the folders "open". Anyway, I rebooted the TC and we are good to go now.”
*Proper Computer Name* #
Make sure your computer has a proper name. Go to System Preferences --> Sharing. Time Machine needs to differentiate your computer from others on your network (i.e. "Bills MacBook" or "Office iMac"). If the "Computer Name" field is blank, create a name. Realize that if this step is necessary, you will likely have to start the Time Machine backup process over again and do another full initial backup.
According to this article, [http://support.apple.com/kb/TS1760], Time Machine may experience problems if your computer name includes certain characters. Make sure the computer name only includes ASCII characters from the following set.
(0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ)
Once a change in the computer name occurs, you should stop and restart Sharing on the affected computer. Uncheck and then recheck Sharing in the Services list on the left.
Let us know if any of the suggestions above resolves your issue.
Cheers!

Time machine error: The backup disk image could not be mounted

Time Machine worked OK for several months. Now I get this error every 10 minutes or so.
I unplugged Time Machine capsule and "Change Disk" in Time Machine options.
Nothing helps, I continue to get this error.
I cannot Enter Time Machine either. "Connecting to Server, Connecting to backup" does not work.
Help please because I will probably have to archive and reinstall Leopard. I need the backups,

It may be that the previous backup attempt was ungracefully interrupted leaving remains that Time Machine can’t deal with.
Stop any current backup attempt. Choose “Stop Backing Up” from the Time Machine menu.
Open the Time Machine Preferences and turn “OFF” Time Machine.
Open your Time Machine drive.
Open the folder labeled “Backups,backupdb”.
Now open the folder containing backups of the computer in question.
Are there any “.inProgress” files there. Delete them by dragging the file to the Trash. Or Ctrl-Click the file and select "Move to Trash" from the contextual menu. (Give this time as deleting a large file on an external disk can take a while.)
Turn Time Machine back “ON”. Now try backing up again.
NOTE: If the above procedure becomes impossible to perform, try accessing the disk image from another Mac. Some have discovered that attempting a repair from another computer succeeds where the original computer failed.
Let us know if any of the suggestions above helped to resolve your issue.

The Backup Disk Image Could Not Be Mounted

I've successfully installed Time Capsule on my network and it is working correctly. I can access it via wireless and choose it from Time Machine. The initial backups go well, and I can access them if I enter Time Machine. However, at some point, it creates a disk image on my desktop and then returns the error The Backup Disk Could Not Be Mounted. The only way to restore everything to normal is to reboot.
I've already dismounted and remounted the drive, so permissions don't seem to be the problem.
Can anyone tell me what's going on and how to fix this??
Thanks!
