After upgrading to Mountain Lion, my LaCie USB 3 drive will not mount

I just upgraded my OS to 10.8 and now my LaCie P'9230 USB 3.0 external drive will not mount. I have re-installed the USB driver and re-booted the computer and drive several times to no avail; any ideas/help?

It's my understanding that LaCie hasn't released a Mountain Lion driver for their PCIe card yet. Sonnet uses a modified version of the LaCie driver and theirs is dead in the water too for that reason-they also warn that their driver won't work with 10.7.5 when it's released.
Indeed, yesterday I pulled the Sonnet USB 3.0 card from my Mac Pro and replaced it with a CalDigit card from OWC; CalDigit has separate drivers for 10.6, 10.7 and 10.8 and I can say that the card works with all three, the first time in 1.5 years that I've had a reliable USB 3.0 connection.

External USB drives will not mount under Mountain Lion

Since upgrading to Mountain Lion, two external USB2 drives that I have will not mount and cannot be viewed in the Finder. The same occurs on a 2012 MacBook Air, a 2009 iMac 27 and a 2010 MacMini, all running OS X Mountain Lion version 10.8.2.
Both drives are Samsung Story external USB drives (one is 1.5 GB and the other is 2 GB) and both have been formatted using Mac Disk Utility with a single Mac OS Extended (Journaled) partition, one using Snow Leopard and the other with Lion.
Both still mount correctly on a friends MacBook Pro that is still running Snow Leopard, and I had no problem with the same drives under Lion. Interestingly both can also be connected to Time Capsule USB port and show up correctly.
Both drives mount correctly under Windows 7 on BootCamp partitions that I have on both the 2012 MacBook Air, a 2009 iMac 27. These BootCamp partitions have Paragon HFS+ installed so I can read Mac formated drives.
Both drives show up in Disk Utility, but when attempt to mount the drives I get the message "The disk could not be mounted. Try running First Aid on the disk and retry mounting." I can run Repair in First Aid on the disk and get the message that the volume appears OK, but again have the same problem when I attempt to mount the disk.
I have also tried using Disk Utility 3,2, but still cannot mount the drives, though the program indicates there is no problem with the drives.
I have other portable USB including a Samsung portable USB2 drive, and two external USB3 drives, and I don't have problems with them.
There is clearly a problem with Mountain Lion with accessing (mounting) these Samsung Story USB drives, and the problem appears to be with Mountain Lion itself as the problem did not occur on the same Macs with Lion and does not occur with Bootcamp partitions on the machines.
I have a lot of time searching forums, but I have not found anyone with an identical problem.
I sure hope someone can help or that Apple come up with a fix for this issue which has only developed since the update to Mountain Lion.

Just installed 7.2 now usb drives will not mount

Only one slot in the back works. they all worked, front and back, untill I upgraded to 10.7.0 and did the updates to 10.7.2.
I have a Mac Pro, Early 2009, 8Gb ram.

I'd put the blame on Lion changed USB external drive support for some types/makes bridges used.
For some, FW stopped but USB still worked.
Do USB ports work iwth other devices or none at all?

Cinema display USB stops working after upgrading to mountain lion

I am using a newly bought 27' Cinema display + mid 2011 MBA. an Apple USB keyboard is attached to the display USB port, and a logitech mouse is attached to the USB port on the keyboard.
After upgrading to mountain lion, when I unplug the thunderbolt from MBA, and then plug it back, the USB keyboard and mouse stops working. Moreover, I cannot open anything in System preference, and cannot properly shutdown the machine!
Please help on this issue.

Launch Terminal, type or copy/paste the following:
killall Dock

MacPro usb very slow after upgrading to mountain lion

When backing up with Carbon Copy to an external USB drive very slow, eventually the system freezes. After upgrading to Mountain Lion its been a complete pain when trying to do back-ups. Does Apple have a USB software fix for this?

Disconnect the external drive and see whether there's an improvement.

After upgrading to Mountain Lion 10.8.2, I cannot print to my Samsung laser printer ML 2525w? How can I get this set up to print?

After upgrading to Mountain Lion 10.8.2 on my iMac, I cannot print to my Samsung B&W Laser printer ML 2525W either by USB or wireless. Any help on how to setup or reconfigure would be apprecaited.
I either print blank pages or prints one time then goes off line, or spits out a bunch of blank paper, etc. Have gone through all the standard fixes, reboot, reset , reload driver, etc.

From the link to the Thread you provided, I worked through the one message procedures that were listed.
For ease of reference, I have copied them and printed them below. This was an old thread but the guidance still works with no firmware upgrade required.
I would stress that you MUST delete any and all files relating to USB connection of the printer to the MAC, including all print drivers (from both Apple and Samsung either from CD or web downloads) and all print queues, etc. I was only able to get the printer to properly hand shake with my Mac by setting it up wirelessly after all old files were deleted with hard power off reboots on both the Mac and Printer.
I hope that someone from Apple will pass this note along to their programing department because there is some type of incompatibility in the new ML OS and the Samsung ML2525w print dirvers used for a cable (USB) type connection. Apple needs to be talking to Samsung to get the USB issue resolved. I am going to post this same message on the Samsung site to see if someone from there will contact Apple to work together on a final solution for USB connectivity.
Here is the steps I followed to get my ML2525w to work in the wireless mode. Again, I cannot stress the need to clean out all the old files (drivers, print queues, etc. - everything) before setting up wirelessly.
As a note, I ran this printer with Lion for almost 2 years and it always worked fine (both wireless and USB). From other comments on the thread, users were good with this printer using Lep. and Snow Lep also. - - no issues from either a USB connection or wireless until Mountain Lion.
Before the fix, I was experiencing many of the same issues as described on user chat threads, printer going offline after a print job. 1st page sometimes printing but all the rest of the pages were garbage. No printing at all. Printer just running a bunch of blank pages out. etc.
I run an iMAC 27" desktop with the ML OS upgrade just installed from Lion.
"I've just installed one of these printers for my parents.
First of all, don't waste your time connecting the ML-2525W as a USB printer. The printer will go offline after each print job. It's hopeless, at least (I assume) until Samsung gets around to publicly releasing a firmware update.
Instead, you have to use the ML-2525W as a wireless printer. In that mode, it works fine.
This is what I did:
(1) First, if you have already attempted to install the Samsung driver software from the included CD-ROM, uninstall it. Get the uninstaller from the Samsung support site:
http://www.samsung.com/us/support/downloads/ML-2525W
Download the "Printer Driver (ver. 4.0)" ZIP file. It unzips to a folder that contains the uninstaller. Likewise, download the "Smart Panel Driver" ZIP file and uninstall the Smart Panel software.
(2) Disconnect the USB cable from the printer, if it is connected. Pull the power plug on the printer and power cycle it.
(3) Restart your Mac.
(4) Go to the "Printer Driver (ver. 4.0)" folder that you previously unzipped. Inside it is a folder named "WirelessSetting". Open the folder and run the "Wireless Setting.app".
(5) The application will ask you to connect the USB cable to the printer. Do so, and the Mac should be able to communicate with the printer to perform the wireless setup.
(6) The application will show you a list of wireless networks. One of them is the wireless interface in the printer (ad-hoc). You can ignore that unless you intend to use the printer without connecting to another wireless network. In my case, I selected the wireless network in my parents' home (infrastructure) and entered the security passphrase. The application then configured the wireless interface in the ML-2525W to connect to the home network.
(7) The Wireless Setting application will then tell you to disconnect the USB cable.
(8) After finishing the Wireless Setting application, go to Word, Textedit, Pages, or Safari, and select a file or page to print. In the print dialog window, you should see the ML-2525W as a "Nearby Printer" (i.e. via Bonjour). Select the ML-2525W, and your Mac will automatically connect to Apple's Software Update and download the latest Samsung driver. If for any reason the Software Update download does not succeed, you can manually download and install the Apple driver using the previously published link in this discussion.
(9) After that, you should be able to print to the ML-2525W whenever you want, without the printer going offline.
(10) If you have a USB printer queue still in your Print & Fax Preferences (from your previous unsuccessful attempt to connect via USB), you can delete it. You only need to keep the Bonjour queue.
Obviously YMMV, but in my case this procedure got the printer working reliably without the need for a firmware update."

HT4798 username/password not working after upgrade to mountain lion

hello, on my imac after upgrading to mountain lion my computer password and/or username seems not to work anymore: when i want to install an update or search for updates on the app store the combination i used so far, does not work anymore. i tried to find out how to reset the computer password but without too much success, and i'm a bit confused, what can i do? thanks a lot

You went wrong at the very beginning by not erasing the hard drive of a used computer before starting to use it yourself. I suggest you do that now.
Back up all data to at least two different storage devices.
Boot into Recovery (command-R at startup), launch Disk Utility, and erase the startup volume. This operation will destroy all data on the volume, so you had be better be sure of your backups. Install OS X. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade, so make a note of those before you begin.
When you reboot, you'll be prompted to go through the initial setup process. That’s when you transfer the data from one of your backups. For a walkthrough, see here:
Using Setup Assistant
Don't transfer the Guest account, if it was enabled on the old system.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.

Imac keeps crashing in time machine backup after upgrade to mountain lion

2008 imac kept crashing (shutdown and restart) during first backup after upgraded to mountain lion. The backup size was about 10GB but time machine crashed after a while (at most 2GB) and never completed backup. So, I don't have any backup since right before I upgraded from Lion. Any suggestion?

Something strange happened. I was able to get time machine to work by going out to the login screen (the account kept logged in) and let it run the backup with the screen off (screen auto off after a few min). I tried it on two different external drives and that did the trick on both. Since the initial Mountain Lion backup was huge (155 GB), I was quite surprise that it worked at all. I assume your MBP was a Lion to ML. I also just did a 2012 MBP upgrade but that one was smoother. I did not recall having crashing issue. One thing I did find during this was that my WD passport USB drive was corrupted. Not sure it was the cause or not. I had to erase and reformat to get it back to work. Maybe do a verify disk to confirm. Good luck.

ITunes doesn't sync iCal with iPhone after upgraded to Mountain Lion

iTunes doesn't sync iCal with iPhone after upgraded to Mountain Lion. I even tried to use Replace Information On This iPhone and it doesn't work. Any idea guys?

I'm having the same problem. It's as if my iPhone and MacBook Pro now have two separate calendars.
Basically, I have a MacBook Pro (Mountain Lion, 13", late 2011) that I sync via USB with an iPhone 4S (iOS 5.1.1). Before upgrading to Mountain Lion, all of my iCal events would sync flawlessly. But none of the events I've created in iCal (Calendars) since upgrading have synced to the iPhone. Likewise, no new events that I create on the iPhone Calendar will sync to iCal. Also, changes to an existing event (even one created before upgrading to Mountain Lion) don't get synced either.
Everything else seems to be syncing just fine though (music, apps, contacts, etc).

With Lion I had 2 user accounts. Why do I have three user accounts after upgrading to Mountain Lion?

I had consistenlty had a master admin user account for myself under Lion, plus the "Guest" account recommended and created by Lion. After upgrading to Mountain Lion, I now have the same 2 accounts, plus a new one called "Other." Why do I have that? Why was it created? How do I get rid of it if it is not needed?

After upgrading to Mountain Lion on my 2011 27" iMac, my Mac occasionally lock-ups.

After upgrading to Mountain Lion on my 2011 27" iMac, my Mac occassionaly locks up while using Safari, Mail or Dreamweaver and I have to d a force-quit, then restart my Mac. Anybody having similar probelms?
I am thinking about doing a clean install of Mountain Lion. Would I be able to restore my applications and data from Time Machine after the re-install?

My 24 inch iMac... 2.8 GHZ dual core (Early 2008) is having the same problem. After it sleeps, I go to use something... and the beachball of death occurs. This happens multiple times a day... and let me tell you... it is annoying... and I am the one who is being annoyed!
It could possibly be revolving around safari... as that is really the only thing that is running consistently. I don't use iTunes on this iMac as I have so many other Macs up and running in the house... and I never consume media on it... so I kind of dismiss iTunes being the culprit.
This is majorly affecting my Mac... in terms of reliability and uptime... which coincedently is the main reason why I switched to Mac in 2008. This is my only Mac that could upgrade to ML... so I don't know how widespread this is... but I hope that this problem can be solved...
I agree with another person who commented on this issue... do we really need a 10.8.1 update already... to fix this?
