The above shows that your external disk is not mounted.
Try selecting it in Disk Utility and then clicking on the Mount button.

[bont100]

yes, this mounting method will not work either.
I've received instruction on how to reformat, I'm hoping it will mount itself and the most important files on the HD are also located elsewhere, but I'd rather not do that without trying everything... anything else I could try?
Thanks for your help

[hayne]

If the disk won't mount, it might be because the filesystem on it is damaged. Try repairing the filesystem with Disk Utility ("Repair Disk") or with DiskWarrior.

[bont100]

repair wouldn't work/help anything. I went ahead and erased and reformatted. Lost some things, but nothing too important.
Thanks for all your help though!

dear hayne,

i have an external drive and recently i have set the permission to no read and write to block other users from accessing it, apparently i have blocked myself and the harddrive icon doesn't show up anymore.

i ran the following command:

id
ls -l /Volumes
echo "done"

and get:

The above shows that your "WD FireWire HD" drive is owned by user "Mom" and has permissions only for owner.
Your user is "Zak" who therefore has no access to this drive.
If you want to make it accessible to all users, run the command:

sudo chmod a+rwX "/Volumes/WD FireWire HD"

Dear Hayne,
I am having the same problem as bkk4life regarding the Phantom external drive because I accidentally set the ownership & permissions to "no access". I have tried to follow the terminal commands I found in this thread but it doesn't seem to be working. Here is my latest terminal input:

done
Brown-Dog:~ cpv$ sudo chmod -R u+rwX "/Volumes/1Tb VWA Archive"
Password:
Brown-Dog:~ cpv$

After restarting, my external drive still doesn't show up on my desktop. Could you help me resolve my problem?

The above result (drwxrwxrwx) from the 'ls -l' on your external drive shows that the problem doesn't appear to be related to permissions since it has full access for all. (See the Unix FAQ referred to above for a full explanation of permissions)

So maybe it isn't showing up for some other reason.
Go into Disk Utility and select that drive (on the left side of the Disk Utility window) and then press the Mount button. What happens?
Note that you should check if it appears in a Finder window - don't worry about it appearing on the Desktop for the moment.
And check your Finder preferences to make sure that there is a checkmark beside the item to show external drives in the Sidebar section of the preferences.

There is another way! It is through enabling the root user.

http://docs.info.apple.com/article.h...en/mh1549.html

I tried following this posting but I couldn't make it work. Through accessing your computer as the root administrator you can rewrite the permissions. It is easy. I am a novice at computers and I did it with no help.

[mintyfresh]

i had the same problem everyone seems to be experiencing. i just googled it and came across this site. i just copied and pasted some of the script you've given others and obviously edited the relevant bits and it worked first time. thanks very much, almost had a heart attack when i thought i couldnt access my hd.

[nkatz]

Phhheewww!

I too made the mistake of changing the permissions on my ext. hard drive via the get info window. I searched all over the web for tips on how to fix the problem. The best solution I found was Prosoft's Data Rescue II. However, I had a feeling I could fix the solution in Terminal before I doled out the hundred bucks for the software. Unfortunately I was scared *****less of doing that as the previous time I got under the hood of OSX, I bulloxed things up badly enough that I ended up having to reinstall my operating system. That, by the way, was also the first time I had tried using Terminal.

Then I found this thread with your straight-forward, well-written advice and the holy grail itself:

Quote: sudo chmod -R u+X /Volumes/iLios

.
After saying a heart-felt novena I pasted the command into Terminal, substituting the name of my hard drive...

And after restarting there was the icon of my old 250 GB Hard Drive filled with original video footage back on my desktop.

Thank you. Thank you. Thank you. Hayne, you are truly a genius.

Please Help!
I am really sorry to be bothering! My problem is that I own a Lacie D2 250 gig drive that I have always pampered. Recently, the USB cable was accidentally unplugged from my MacBookPro. After that, I can no longer see the Lacie drive icon on my desktop. If I use the disk utility, I can see that the drive is mounted and can unmount it if I want. It seems that the drive itself is healthy. No noises or flashing lights. Just that the icon is gone!

I have done a disk repair on the drive. It said one permission was restored, but still no icon. Looking on your forum help advice with similar issues to this, I did type the following commands on “Terminal” which I saw on the forum page:

id
ls -l /Volumes
ls -ld /Volumes/PEEWEE
ls -ld /Volumes/PEEWEE/wip
ls -ld "/Volumes/PEEWEE/wip/Ballet 4 graeme"
ls -l "/Volumes/PEEWEE/wip/Ballet 4 graeme/ballet.lso"
echo ---------------

After that I got the following info on “Terminal”:

My-Computer:~ DGPro$ id
uid=504(DGPro) gid=504(DGPro) groups=504(DGPro), 81(appserveradm), 79(appserverusr), 80(admin)

I don’t know what to do exactly from here in order to fix the problem. I am not very familiar with the myriad of codes in Terminal and what they actually do, but I am a good listener and can carry out any advice or direction that you can help in restoring my drive, which has priceless family photos. Thanks.

HELPP!!!!!!!! I am literally crying!!! I am having the same problem like everyone else. Tried, and typed everything that I saw on this post, and still doesn't seem working. I have 2 Maxtor one Touch hard drive, that I did to both of them, and I have a deadline in 2 weeks. I have all my data in it. While mounted them at work, I accidentally (now knowing it would result this) checked "ignore ownership". Please, please, please HELP! I appreciate every feedback, as I am miserable now

[splash]

I did the #129 and it WORKED!!!!!!!!! thank you so much Cdino! You saved my life! I had so much work in those two drivers!

[ejbevan]

Hey,

I have a similar problem to others here! I have a Buffalo 250GB external drive, and I have accidentally manage to uncheck Ignore Ownership Permissions on this external drive. It shows up in Disk Utility as an orange USB drive with standard file icon below, and I can't access it in Finder, I have an alias to it on my dock which, when clicked says:

"The application "(null)" cannot be launched.

-5000"

The disk has an awful lot of school work on, some I could really do with it back!

Hope someone can help,

Thanks,

John

[hayne]

ejbevan:

Please open a Terminal window (Terminal.app is an application in /Applications/Utilities) and then copy & paste the following commands (all together) into the Terminal window, then press Return, and then copy & paste the full contents of that Terminal window back here so we can see it:

id
ls -l /Volumes
df -h
echo "done"

[thepat20]

Hi-

I recently bought an external HD, and it does not mount properly in leopard. When i turn it on, i can hear the platter spinning and it sounds like it was working.

The Terminal Commands Return This:

Macintosh-3:~ billyjean$ sudo chmod -R +rw/Volumes/NewVolume
Password:
usage: chmod [-fhv] [-R [-H | -L | -P]] [-a | +a | =a [i][# [ n]]] mode|entry file ...
chmod [-fhv] [-R [-H | -L | -P]] [-E | -C | -i | -I] file ...
Macintosh-3:~ billyjean$ sudo chown root/Volumes/NewVolume
usage: chown [-fhv] [-R [-H | -L | -P]] owner[:group] file ...
chown [-fhv] [-R [-H | -L | -P]] :group file ...
Macintosh-3:~ billyjean$ sudo chgrp wheel/Volumes/NewVolume
usage: chgrp [-fhv] [-R [-H | -L | -P]] group file ...
Macintosh-3:~ billyjean$


It is a 360 gig External Maxtor Personal Storage.
It does not show up in Disk utility, but sytem profiler recognizes it under

USB ->USB High Speed bus ->
Maxtor 3200:

Hi Hayne,

I am thoroughly impressed with your knowledge of this. Like so many I found this thread through google and am amazed. I hope somebody is paying you well with all that info you have stored in brain!

I have attempted to use the info in other threads but am getting stuck when it comes to me putting in my password.

I tried reading the unix thread you recommended but do not see the revelance to the password issue that I am having.

here is my code...

The fact that you didn't get prompted for your password when you entered the last two commands would seem to mean that you had entered it correctly above (the second try).
And (as explained in the Unix FAQ referred to above) the fact that you got no output from the 'chmod' command would seem to mean that it worked.

Have you tried to see if all is well now?

[whynot]

Yes, after the computer booted up this morning it indeed did appear on the desktop.

Could you please direct me to where I can show my gratitude for the information on this page with a donation?

Thank you.
