I am trying to use a 3.0 thunderbolt device and the enclosure has a usb output for multiple usb drives. I ten the recent OSX update recently and now my usb HD with 1.5 TB of audio sessions won't work....HELP?!?!?!
MacBook Pro (13-inch Early 2011), OS X Mavericks (10.9.4)
Well, the first thing to do is to check all your cable's and connections to the drive. Be sure the power is properly connected and turned on. Shutdown the computer and wait 30 seconds. Connect the drive to the computer. If you drive supports USB then use a USB cable, otherwise go with your your Thunderbolt setup. Power up the computer. Does the disk icon show up? If not then open Disk Utility and look in the sidebar. Do you see a listing for the drive? If you don't, then there's a problem, but what, exactly, is hard to know. It could be:
Any of the above are possible. I would take your computer and the drive in for a diagnosis to your local Apple retailer.
Now, if you do get the drive to show up, then I would use Disk Utility to repartition and re-format the drive:
Drive Partition and Format
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Apply button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
So my device isn't showing up which means that it is corrupted? I look for it under the utilities section and it finds it but it says S.M.A.R.T.- not supported I believe.....sadly it has never done this before but it's not seeming hopeful. Not sure what to do except not buy a "deal" for a Toshiba from Best Buy again lol....Thank you Kappy
I couldn't say. You haven't provided any information about what is happening. The drive could be corrupted, but you could reformat it if it shows up in Disk Utility. SMART is not supported for external drives. As for Toshiba I'm using a Toshiba external drive on a Mid-2010 iMac without a problem.
yeah sorry. I plug in the device either through the thunderbolt connection or via the USB port on the side of my MacBook... Usually it takes a few seconds and loads up but after my latest update it hasn't shown the icon on the desktop like normal. Everything I've read thus far and experienced like this before with a few other drives before points to a corruption but I am a drummer and audio engineer so computers aren't my forte.... You may know a lot of other things I haven't thought about.
You don't. The OS X drivers are only updated when OS X is updated.
how do I update the usb 3.0 drivers on my Mac?
