OSX does not automatically mount external drives for a user

I'm having a problem where external drives are not mounted automatically in one of my user accounts. This is independent of the format of the drive, ability, or port. Driving, if the drive flash, hard drive or SD card, must be installed manually in disk utility. It appears dimmed under external and I select the mount option. Once I do this drive works normally.

This only happens in one of my user accounts. Into account other external drives come up automatically and displayed in the Finder and the desktop. Users have permissions admin, no parental control is activated. The only difference I know is the user account that does not correctly use iCloud as login.

The details of the device/osx are:

MacBook Pro (retina, 15 inch, mid-2015)

10.11.2 version (15 c 50)

So far I have used first aid on my boot drive, run Apple Diagnostics (no problem found) and reset the NVRAM.

Please read this message before doing anything.

This procedure is a diagnostic test. It is unlikely to solve your problem. Don't be disappointed when you find that nothing has changed after you complete it.

The test is intended to determine if the problem is caused by a third-party software that loads automatically at startup or logon, by a device, by a police conflict or corruption of system files or some system caches.

Disconnect all devices wired except those required to test and remove all the expansion cards from secondary market, as appropriate. Start in safe mode and log on to the account of the problem.

Note: If FileVault is enabled in OS X 10.9 or an earlier version, or if a firmware password is defined, or if the boot volume is a software RAID, you can not do this. Ask for additional instructions.

Safe mode is much slower to boot and run as normal, with limited graphics performance, and some things work at all, including an audio output and a Wi - Fi connection on some models. The next normal boot can also be a bit slow.

The login screen is displayed even if you usually connect automatically. You need your password to log on. If you have forgotten the password, you will have to reset it before you begin.

Test in safe mode. Same problem?

After testing, restart as usual (not in safe mode) and make sure you always have the problem. View the results of the test.

  • Windows 7 backup function does not recognize the external drive connected to the wireless router

    I installed a Belkin router for my laptop and pc, it came with a usb port so that I can connect my external hard drive directly and share it as a backup drive.  But when I tried to set up in Windows 7, the backup options list.  The network recognizes it, but Windows will not let me select it as backup destination.  A buddy of mine said that the backup of Windows 7 does not work with network drives, but no matter who else thought of it?  Thnx.

    It depends on the flavor of Windows 7. The Home Premium version will not network disks, backup but the Ultimate version. You can connect your drive as a USB drive when you make your backup.

  • Disk utility does not see an external drive on my network

    I'm trying to reformat the external drive that I use for backup on Time Machine, but disk utility does not see it. She appears in the Finder as a shared drive. I use OS x 10.11.6. Thank you.

    Disk utility is not supposed to see the network drives.

    If it's a USB, connect it to your computer.

    If it's an Ethernet or wireless, using a utility specifically designed for this.

  • Backup Restore Time Machine does not see RAID external drive

    Hi all

    I have a problem with my iMac restore from a Time Machine backup, and I was wondering if anyone else had the same problem already.

    I had to reinstall OS X El Capitan from scratch, based on education, I received Support from Apple. That worked without problems and my iMac works fine. However, I wanted to restore it to how it was before, using Time Machine. I keep my backups on a LaCie 5big Thunderbolt 2 and never had any problems with it.

    To restore the system, I followed the instructions on the Support page. I restarted my system in recovery mode and selected the "restore from Time Machine backup". Unfortunately the LaCie 5big does not appear on the list of drives, so I'm stuck... When you use the system in normal mode, the external RAID is visible and Time Machine stores backups on it without any problem.

    Any of you are familiar with this problem? I would be very grateful if you could help me with this problem!

    Kind regards

    Valerio

    Hello

    -While the system is booted in recovery mode, confirm that the Lacie 5big network is visible in disk utility.   You will need to disconnect / reconnect the Thunderbolt cable to the Lacie 5big be detected.

    -Once seen, a new attempt to restore from Time Machine backup.

    See you soon

    Hello

    where to download the driver? On the European site? Maybe you should try the Canadian site, they sometimes have some drivers who hasn´t europe and maybe you can find the audio driver that matches:

    http://EU.computers.Toshiba-Europe.com/cgi-bin/ToshibaCSG/download_drivers_bios.jsp

    Otherwise, there is another option: find out which audio chipset is installed, visit the website of manufacturers of this chipset and download the drivers. Him to work.

  • OfficeJet 7210 printing preferences does not work with the driver for Windows 8

    I have successfully installed the driver of Windows 8 (64 bit) full of features.  Printer copy, scan, fax and print from the computer.  However, I'm no longer able to print in grayscale, select a print quality (fast draft, project, etc.) and choose the paper type on the printer menu shortcuts in the printing preferences.

    In the box "what do I want?" and choose fast/economical printing, the selections above will appear in the list of options, but when you go to select an option in the drop-down lists that can empty al.

    You probably work with a more basic driver in Windows 8, and this is why you are not able to use these features. I would check to see if there is another driver that will allow you to use the. Here's a message written by a colleague who deals with how you can do this:

  • Portege Z930-118 does not recognize the external USB CD/DVD drive

    My new Z930-118, with windows 7 64 bit home, does not recognize the external CD/DVD drive when I plug it into the USB port.

    The CD/DVD device does not even appear at all in Device Manager.

    The reader is a SE-S084 Samsun and works well on another laptop.

    I already checked for the "upper_filter", "lower_filter" with the regedit, but entries are not there, so no help.

    Hello
    I m not very well how to help you.

    I found some information about this WEIRD disc and it seems that he didn't need an external power supply. Its USB bus powered so I guess around 500mA power since it is the default value provided by a USB 2.0 port.

    I don t think that there is a problem of missing software. It is a plug n play device so you need to connect it to the USB port and the system should automatically recognise.

    From my point of view of the few you try to connect the external USB ODD two ports to aid a * Y * Cableusb.
    I think the reader needs more power provided by a single USB port.
