• 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

• iMac does not recognize the external speakers

  After working flawlessly for two years, my iMac (running Mavericks) now does not recognize my speakers B & W MM1.  I restarted my iMac, unplugged and reconnected my speakers as well from the electrical outlet and the USB connection, but nothing has worked so far.  All other connections are solid.  Any suggestions?  Thank you.

  Hmmm. These speakers are USB, so they should be relatively problem-free.

  Try to disconnect all your USB devices, restart, and then reconnect the USB devices again. It remaps the USB.

  In addition, make sure the configuration under the system preferences/Sound/output is correct.

• Win 7 64 does not see disks external usb 3.0 at startup

  I have a 3 TB usb 3.0 drive external which is plugged into a usb port 3 on my Windows 7 Asus computer. At startup, the computer see this player. If I inplug the power from the USB and plug it in again, the computer sees the drive and all is well.

  If I plug this drive into a usb 2.0 location, the computer sees it at startup. I would like to be able to use the speed of the usb 3.0 slot, however.

  I installed a new driver on the seagate site (all on the phone with technical support of seagate). This did not help. The man said he thought that the problem was probably in the settings of the bios of the computer.

  In Device Manager, I've uninstalled the USB mass storage device element which had a '! ' and then right click and choose scan for hardware changes. Scan the computer, and then try to install the drivers, then the error message that says that the driver installation failed, without explaining why.

  Help, please

  I thank each of you for your attempts to answer this question!
  YES, microsoft 'fixed' the problem that was part of the addition of service pack 1 for win 7.
  It seems that the transition "done something" to how usb 3.0 drivers worked. Or in my case, didn't work. After you apply the fix, everything seems TSE be as it should have in the first place.

  You can close this one!

• VMFS does not see the measuring devices?

  I ran into a problem with my ESX 4 deployment.  Recently, I expanded the size of a LUN in my SAN so that I could extend the data store associated with this volume.  The data store recognizes the new 300 GB size (image vmfs_prop), however, I'm not presented with options for a measuring device when I try to 'increase the ability to data store' (image vmfs_increase).  I've also updated the filter of vmfs in options advanced thinking that LUN was already associated with the data store and may have been filtered (image vmfs_filter).  Any advice?

  

  

  

  What I meant with "connect directly to the host ESX (i)" has been to connect by using the vSphere Client. Generally, you don't need to use the command line. Have you tried that before the more command line data store? It does not work?

  All hard disks have finishes by fail.  Which may occur to your 1 TB HDD Mactor.

  Save your MBP on another HARD disk.

  Then look for hardware problems.  Using different USB ports.  Try different USB cables.  Remove the HARD drive and install in another known functional pregnant.  Test it on another Mac.

  If no success, then test it using disk utility > first aid.
