For the last month or so, I have been receiving notification windows in the upper right-hand corner whenever a volume is mounted or unmounted (i.e. portable hard drive, Time Machine, etc.) How do I turn these notifications off?

As far as I know, this isn't built in to the system. Do you remember installing any software to trigger this? Also, do you just mean that an icon appears on the desktop, or a real notification box appears? – Nathan Greenstein Mar 20 '11 at 14:05

If Growl is installed and you want to turn off just the notifications for volume mounts and dismounts (as opposed to getting rid of Growl altogether):

  • System Preferences, Growl panel
  • Applications tab
  • Select HardwareGrowler from the list
  • Configure
  • Notifications tab
  • In the dropdown, for each notification (e.g. Volume Mounted) you want to disable:
  • Select it and untick the 'Enabled' box.

(Edit:) Or, as fnurl points out, remove HG entirely. I find it useful enough to keep, but tweaked to my liking. It alerts me if my WiFi starts bouncing, f/ex. YMMV, as always.

Check to see if you have Growl installed - it will be in System Preferences. Sometimes applications install it without your permission - even though the growl team explicitly don't allow it. Its safe though, I use and love the product.

I use HardwareGrowler to get these messages.

Perhaps HardwareGrowler is launching at startup? If you do not want this, go to

System Preferences → Accounts → Your Account → Login items

and find HardwareGrowler and remove it from the list.
