OS X 10.6.8 - None of my usb flash drives are mounting. They don't show up in disk utility either.  System proflier does show the flash drives.  I've run disk warrior and the flash drives show there as well.  I've tried all of the usb outlets with several flash drives and none of them show up.  I can use the same usb outlets to use my wireless keyboard, mouse and also my ipad.

 

Finders preferences are all checked to show items on desktop.

 

One of my flash drives I tried several times and finally got this screen message. "System extension cannot be used  The system extension "/System/Library/Extension/IOStorageFamily.Kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update.   Non of my other 6 flash drives mount and they do not receive any screen message. 

 

I've also run repair disk permissions several times and the it says permissions repaired so I run it again and the same issued it said it was repaired, it lists again. I've done this several times with the same results.

iMac, Mac OS X (10.6.8)

    Hello

     

    from that

     

    "System extension cannot be used  The system extension "/System/Library/Extension/IOStorageFamily.Kext" was installed improperly and cannot be used"

     

     

    try this

     

    - boot from your original system disc

    - plug one of your usb flash drives

    - see if installer software could use usb flash drives as target for install

    ( testing your usb flash drive from a know good system software )

     

    - DO not perform install on flash drive , just need to know if flash is usable

     

    if it could , re-install your system or if it was updated from a previous version re-install 10.6.8 combo update

    checking for any missing update ?

    Re

     

    Regarding boot from your original system disc-- I have iMac Mac 0S X install Disc 1 and Disc 2 are these the system disc?

     

    yes disk 1 is for basic system inslall and disk 2 is for complement and computer test ( AHT )

     

    Use disk 1 for test

    Assuming they're grey ones, yes. Disc 1 has the installer, disc 2 has iLife and possibly some other bundled software.

     

     

    Edit;

    Slow again! Snap! Pierre

    Re

     

    first shut down your imac by pressing start up buttom for more than 10 second

     

    unplug all peripheral , usb drive , printer ... ect

     

    then startup again and see if universal no sign and the spinning circle come again ?

     

    if yes then put in drive your system disc 1 , shut down , start up again but just after start up sound hold C key at

     

    keyboard to start from system disc , folow at screen instructions to install your system .

     

    then one more time update your system to last possible version , using system software update from apple menu
