Drive no longer available as TM target in Mountain Lion

With Lion, I had an external drive attached to my Mac Mini Server and used it as a network Time Machine target to backup my laptop. I just upgraded my Mac Mini Server to Mountain Lion with the Server upgrade and now the drive no longer shows up as a target.
I read through all pages at http://pondini.org/TM/Troubleshooting.html, reformatted the drive, double-check File Sharing permissions, and it still doesn't show up. It mounts just fine on the client laptop through Finder. Has something changed in Mountain Lion?

Sounds like the same problem I'm having. My external drive mounts just fine on my Lion-based machines, but on my Mountain Lion machine it not only will not mount, but when I try to Repair in Disk Utility it tells me:
"Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files."
Since it mounts fine on my Lion machines, I know there's nothing wrong with the physical disk or the filesystem, so I'm not going to the trouble of reformatting and restoring. Instead I think I'll just "upgrade" back to Lion.
I'm having several other usability issues with Mountain Lion as well. What gives with this OS, Apple??

Shared drives no longer network accessible on iMac running Mountain Lion.

Hey all,
I've been searching the community on and off for weeks and have not been able to come to a solution. I have an external hard drive connected to a 2007 iMac running Mountain Lion that has successfully been shared on my network for over two years starting with Snow Leopard. Just recently I noticed the shared drives were no longer showing up on my networked Macs (running anything from Leopard to Mountain Lion). What's odd is the shared drives will connect and show up for the first 5 minutes or so after the iMac is restarted, but will go offline soon after. The iMac shows up in the side bar, but I get the dreaded "Connection Failed" message in Finder when I click "Connect As" after the shared drives first go away. Screen sharing works fine all the time when accessing the iMac. I've tried everything on the iMac from disabling the firewall completely to renaming it on the network to disabling SMB on all shared partitions. Anyone have any suggestions?

What version of OS X are you installing on the external drive? Is the drive partitioned GUID and formatted Mac OS Extended, Journaled?

I have a free agent desk 500GB external hard drive. Since updating my iMac OS to mountain lion recently, it will no longer backup, stating "an error occurred while creating the backup folder". Can anyone help me with this?

I have a free agent desk 500 GB external hard drive. Since updating my iMac OS to Mountain Lion it no longer backs up through Time Maching like it did in the past. Now, after completing its work it says, "Unable to complete backup. An error occurred while creating the backup folder." I cannot find any sites that help me fix this. Do I need to purchase a new external hard drive?

Can't imaging something not being covered there.

How long does it take to reinstall Mountain Lion on a new hard drive?

Due to performance/corruption issues, I erased my MacBook pro's hard drive. Now, I'm attempting to reinstall Mountain Lion (then do the upgrade to Mavericks). However, after about 5 hours of it doing the reinstall and downloading files (I have it connected to a network cable), I went to bed.
At some point during the night, the process seems to have timed out. Evidently, I will need to start from the beginning of the installation process.
My Questions:
How long should I take?
Is there a way I can prevent the MacBook from going into sleep mode so I can leave it unattended?
Since I've worked in corporate IT, I'm more than familiar with the Windows reinstall process and generally know what's going on and how long portions of an installation should take. Is there a way I can have the installation tell me what's going on?
Any other tips/tricks or general information?
Thank you for any assistance.
Rich

Wish I had your DSL speed. iTunes suggests I have about 7 1/2 hours still to go! Just glad it is giving it it's best shot.
Thanks for your reply.

how long does it take to install mountain lion

It depends on a number of factors - the speed of your computer and hard drive mostly. My experience has been that a standard upgrade will take 30-45 minutes. If you are erasing the hard drive and installing, it takes about 20-30 minutes, not counting migrating your data and applications.
This doesn't count downloading which can take as litting as 40 minutes (a very fast broadband connection during off hours) to as much as several hours.

Take each of the following steps that you haven't already tried, until the problem is resolved. Some of these steps are only possible if you have control over the wrieless router.
Step 1
Turn Wi-Fi off and back on.
Step 2
Restart the router and the computer. Many problems are solved that way.
Step 3
Change the name of the wireless network, if applicable, to eliminate any characters other than letters and digits. You do that on your router via its web page, if it's not an Apple device, or via AirPort Utility, if it is an Apple device.
Step 4
Run the Network Diagnostics assistant.
Step 5
In OS X 10.8.4 or later, run Wireless Diagnostics and fix the issues listed in the Summary, if any.
Step 6
Back up all data.
Launch the Keychain Access application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Keychain Access in the icon grid.
Enter the name of your wireless network in the search box. You should have one or more "AirPort network password" items with that name. Make a note of the name and password, then delete all the items. Quit Keychain Access. Turn Wi-Fi off and then back on. Reconnect to the network.
Step 7
You may need to change other settings on the router. See the guidelines linked below:
Recommended settings for Wi-Fi routers and access points
Potential sources of interference
Step 8
Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
Step 9
Reset the System Management Controller (SMC).

Long pause after login screen on Mountain Lion

Here's some strange behaviour I noticed on a quite fresh and clean install of Mountain Lion:
There's a long pause (around 10 sec) after I type my password in the login screen until the Desktop is actually shown. The funny part is: if I hit the key for Mission Control during that pause, the I'm able to see the Desktop and interact with it, while the login screen is moved to the side. The Finder is fully usable but as soon as I start an application, the login screen moves back in and covers all until finally the login animation is displayed.
I never experienced that behaviour before and always had the whole boot process in less than 15 secs. Now it takes up to 30 secs until I see the desktop.
I already tried a lot (HardDisk Utility, permissions, LaunchAgents, LaunchDemons, StartupItems etc) with no luck. Theres nothing in the Konsole for this pause.
Any ideas? My world won't crumble about this but I'm curious what might cause this delay.
Thanks in advance,
Arroyodorado

I had no luck with that one either. Maybe Mountain Lion is not longer accepting that particular command setting. Thanks for trying to help though. If you ever find out please give me a shout.
To recap, the Terminal commands...
sudo defaults write com.apple.driver.AppleBluetoothMultitouch.trackpad Clicking -int 1
and
# Enable tap to click on a Magic Trackpad
defaults write com.apple.driver.AppleBluetoothMultitouch.trackpad Clicking -bool true
# Enable tap to click for the active user
defaults -currentHost write NSGlobalDomain com.apple.mouse.tapBehavior -int 1
# Enable tap to click on the login screen
defaults write NSGlobalDomain com.apple.mouse.tapBehavior -int 1
... have not worked when using OSX Mountain Lion.
Has anyone else got any other options we could try?

Can No Longer Get Camera Photos After Installing Mountain Lion

After installing Mountain Lion, I am no longer am able to see pictures from my digital camera thru the USB port. This camera has worked for years with my iMac, but not anymore. Anybody else having this issue after installing the newest system?
Dick

Paul_31:
I have not tried to import the photos directly into iPhoto. However, I did remove the SD card from the camera and plug it into a USB card reader, and my iMac would NOT read the photos that way either. I took the camera and plugged it into my Win. 7 laptop and the pictures showed up nicely, so I know the camera and the card are Ok. My iMac has been working strangely since I installed Mountain Lion. I'm getting lockups using iMovie too.

How long should it take to download Mountain Lion?

How long should it take to download and install Mountain Lion? I have been downloading it for about 5 hours and it still has 1 gig to go. My current OS X is 10.7.4

It depends on what bottlenecks you have interposed.
If you have a fast Ethernet connection, not cable Internet, that is not throttled by your ISP, and are using fast Ethernet on your local network, you should be able to download in about an hour.
If you are transmitting it over your wireless connection, it may take substantially longer.

How long does it take to download mountain lion

just downloading mountain lion on my imac ( MAC OS X 10.7.5) ---any idea how long it should take? its starting to look like its going to be slow...

That's around 1.6 MB/s or approximately. So it should take about one hour at that speed. However, your service speed is not necessarily the transfer speed between you and the Apple servers. Expect the actual time to be longer.

How can i get a printer driver for my HP desk jet 3050a for mountain lion

I just bought HP deskjet printer for my son 3050 seriers and how we cant print. We need a driver to support mountain lion 10.8 and at the HP website they have up to 10.7. help please.

I have the HP 3050A and I have just updated to ML. One of the first things I tried was printing/scanning, works OK, I presume ML includes the correct drivers if you already have it working in Lion.
Sorry cannot give more information other than that it worked for me.
