unmounting hard drives?

[fruitylooper]

in osx ive got 3 hard drives that show up, the osx partition the windows partition and a dell utilty partition.

the dell utility partition is useless to me and i dont want it to be visible from osx.

ive tried unmounting it from disk utility but it comes back every time i reboot. can anyone help?

 

also how do i rename drives for osx (but not for windows).

 

thanks

Rename drives - click on the icon of the drive and hit Enter. Type a new name. Hit Enter. Same for any OSX file/folder. Or click on the icon, Get Info on it and change name there.

 

Unmount drives - In Disk Utility, click on the Dell partition. At the bottom of the window, find the Mount Point. It should be /Volumes/(some-partition-name).

 

Make a text file called: rc.local (Make sure it is called rc.local and not rc.local.txt - Use Get Info on it to verify)

 

In the text file, put the line(s): diskutil unmount "/Volumes/(some-partition-name)"

If the name has spaces, be sure to use the quotes.

 

In Finder, Go menu -> Go to Folder -> type: /etc -> click Go

 

Drag the rc.local file to the etc folder. It will ask you to Authenticate. Click the button and give your password.

 

Run Disk Utility and repair permissions on your OSX partition

 

Reboot

hmm have tried this many times and it doesnt work, did you maybe make a mistake in the text line?

 

thanks

The file has to be called rc.local.

 

Go to Terminal and type:

cd /etc
ls rc*

Is the file named rc.local or rc.local.txt?

 

If the partition that you want to unmount is called "No {censored}" then the command inside of rc.local should read: diskutil unmount "/Volumes/No {censored}"

You get this from Disk Utility at the bottom: "Mount Point"

 

Be sure you repaired permissions using Disk Utility.

the file is rc.local not rc. local.txt and it reads:

diskutil unmount "/Volumes/DellUtility"

 

in disk utility the mount point is /Volumes/DellUtility

 

i have repaired disk permissions every time ive tried.

 

i cant see that im doing anything wrong.

[Rammjet]

the file is rc.local not rc. local.txt and it reads:

diskutil unmount "/Volumes/DellUtility"

Try it manually in Terminal: diskutil unmount "/Volumes/DellUtility"

 

Note: you only need the quotes if the name has a space in it.

this was just the same as unmounting from diskutility - the drive came back after reboot.

 

oh well, im sure i can live with it

[Rammjet]

this was just the same as unmounting from diskutility - the drive came back after reboot.

Yes, yes. That was just a test to verify that the command in the rc.local file was working on your system. Now it is time to diagnose why rc.local isn't doing its thing.

 

Fire up terminal and type the following and copy/paste the results here.

 

ls -al /etc/rc* ; cat /etc/rc.local

[fruitylooper]

ok, here are the results

OK, I see 2 problems - file format and permissions.

 

The biggest problem is that when you made the file in TextEdit, you created it as an RTF file. This file contains information for fancy formatting of the text. You needed to create a text file. See all that {censored} listed in the file before your "diskutil unmount" command? That is formatting data.

 

In TextEdit, open a blank document, go to Format menu -> Make Plain Text. Then type your command in the document. When you save the file, give it the name rc.local and be sure to UNcheck the box near the bottom about the .txt extension.

 

Drag the document to the /etc directory. Then go to Terminal and type the following:

sudo chown root:wheel /etc/rc.local
sudo chmod 644 /etc/rc.local

Then reboot.

success,

thanks rammjet
