View Full Version : Mounted volumes not showing up on desktop

-----------------
The computer I'm using is:

Machine Name: Power Mac G4 (AGP graphics)
CPU Type: PowerPC G4 (2.6)
CPU Speed: 450 MHz
Memory: 1 GB
OS Version: 10.4
-----------------

I was running 10.4.6, and one day all of the sudden my mounted volumes (one FW, one USB) just quit showing up on my desktop as icons. Naturally (after unplugging/replugging both drives) I checked Disk Utility to see what was up, and the FW one was still listed, but the USB gone.

Since I also own a newer PB G4, I went over and plugged both drives into the laptop, and they came up just fine. So I ended up just restarting and trying tons of things to get the drives to show on the older Power Mac, but nothing worked. In the end I finally just did a clean reinstall of osx, figuring that would solve the problem once and for all.

But it didn't!

I am clueless on what to try next... any suggestions? The FW drive still shows up in Disk Utility, but with no icon on the desktop or in the finder menu (where the drives are listed in each window). Disk utility tells me it's mounted at "volumes/misato" (misato is the name of the drive).

Thanks!

Are any showing up in Finder? Either in the Side Bar or under the computer name where the Harddrive, Network, and any Optical Disk may be?

Yes, sorry, should have mentioned that. The main internal hard drive shows up fine. In fact, everything else works fine. It's just the external hard drives that don't show.

The icons for the hard drives showing up (or not) is a separate issue from whether these drives are getting mounted.
The latter is far more important.
You said that the Firewire drive shows as mounted in Disk Utility.
Good. Presumably you can access the files on it by using the "Go to folder" menu item in Finder's "Go" menu and typing in /Volumes/misato
If so, then the only problem with that drive is the icon missing in Finder. For that you need to check carefully the Finder preferences.

If the USB drive is not showing up in Disk Utility, that might indicate a hardware problem with your USB port. Do other USB devices work in this port? Is this a drive that gets its electrical power from the USB port? If so, the USB port may not be giving it enough power. There have been lots of reports of USB drives that take more power than is defined by the USB spec - these drives may work on some machines and not on others. Best is to use a powered USB hub with them.

Alright.. with Firewire drive "Misato", I checked the Go To Folder command.

It said folder "was not found". I tried multiple spellings/caps formations.

With the USB drive, it does not get it's power from the USB port. It gets power from a seperate wall wart type power plug. I tried switching the USB port it was plugged into multiple times, but it never mounted.

With the two external drives plugged in and powered up, restart your Mac and then let's look at the situation using Terminal:

Please launch the "Terminal" application (under /Applications/Utilities) and copy & paste the following commands, press Return, then copy & paste the results back here so we can see:

id
ls -l /Volumes
df -h
system_profiler SPFireWireDataType
system_profiler SPUSBDataType
echo "done"

The above shows that the "Misato" drive is mounted but that there is a permissions problem. Somehow you have changed it so that owner (colinlar) has no permissions at all on that folder (the top level folder of that drive).
I.e. the situation is the same as that of this older thread:
http://forums.macosxhints.com/showthread.php?t=44391

Run the following command (in a Terminal window):

sudo chmod -R u+rwX /Volumes/Misato

The USB drive is not showing up in the results from System Profiler.
Try disconnecting your Macally USB devices, then restarting your Mac and try again with the USB drive.

In addition to removing the Macally devices from your computer, also use a new or known-good USB cable on the USB drive in place of the existing USB cable, plugged directly into the computer's USB port.

Hooray!

I have no idea how the permissions for the drive got changed... I usually don't make it my intent to go around changing such things, and I clearly remember not touching anything permissions related between the time the drive was working and not working. Bah, whatever.

Either way, thanks! Now if I could just get these things to network correctly easily. ;)
