Q: Unable to view 1TB Fusion disk

MacMini with 1TB Fusion Drive. I can only see the SSD  showing that I only have 120GB of storage. Cannot see the 1TB

disk. Does this mean that the 1TB disk has failed?

iMac, Mac OS X (10.6.8)

A:

The hard drive isn't working.

Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. You may have to leave the machine there for several days.

Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional—ask if you need guidance.

If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

Keeping your confidential data secure during hardware repair

Apple also recommends that you deauthorize a device in the iTunes Store before having it serviced.

*An SSD doesn't need to be zeroed.

    This procedure is a diagnostic test. It makes no changes to your data.

    Please triple-click anywhere in the line below on this page to select it:

    { diskutil list; echo; diskutil cs list; } | pbcopy

    Copy the selected text to the Clipboard by pressing the key combination command-C.

    Launch the built-in Terminal application in any one 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 and start typing the name.

    Paste into the Terminal window by pressing the key combination command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.

    Wait for a new line ending in a dollar sign ($) to appear below what you entered.

    The output of the command will be automatically copied to the Clipboard. If the command produced no output, the Clipboard will be empty. Paste into a reply to this message.

    The Terminal window doesn't show the output. Please don't copy anything from there.

    If any personal information appears in the output, anonymize before posting, but don’t remove the context.

    Linc.......thanks very much for your help. The MacMini is covered by an Apple support contract....and I have a local authorized service provider.

    I have two Time Capsules that Time Machine backs up to..........when I became suspicious of the hard drive I also started doing backups to a portable Seagate drive. So believe I have it covered.

     

    Again, thanks very much for your help.
