External PHANTOM Drive (no access) Permission, Disk Utility, Mounted, Terminal Code - Page 6

Woodman0682 · 01-07-2007, 12:13 PM

Hi I have a problem with my external HD (lacie 300g) which used to show on my desktop then disapeared for no reason.
I rang mac help and they told me to start a new log in user account, the drive then appeared in this new accounts desktop.

However the drive would only give me read permissions and could not record any more information to it. I then went to Apple i for information and tried to change permissions and the drive disappeared.
I cannot get it back by changing account details and drive does not work on any other apple computer.

I tried all usual disk repair stuff, and mac info tells me that the drive is mounted in the firewire port but i cannot find a way to access it.

I have read the other items on this forum but I have a very basic knowledge of computers and do not feel confident in just typing any old thing into terminal. I have tried which is the mount point????

sudo chmod -R +rw /Volumes/Dans 300G HD
sudo chown root /Volumes/Dans 300G HD
sudo chgrp wheel /Volumes/Dans 300G HD

comes up with this

One of the problems you are having with the commands you tried to run is that there are spaces in the name of your external hard drive and hence you need to enclose the path name in quotes.

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
ls -l "/Volumes/Dans 300G HD"
echo "done"

Hey

Thanks for getting back to me so quickly i copied the above into terminal and it came back with this

The above shows that the top-level folder of your external drive has no permissions for "owner".
To fix this, copy & paste the following command into a Terminal window, then press Return. You will be asked for your password.

sudo chmod u+rwx "/Volumes/Dans 300G HD"

That should fix it immediately - no need to log out or anything.

Woodman0682 · 01-08-2007, 10:17 AM

Ok thats brilliant

I have my files back and can access them, the drive is up and running on the desktop.

The only problem I have now with this drive is that is set to "transfer" only. When i try to run any audio on drive it comes up with:

This session is saved on a volume set to "Transfer" only.

If permitted, set the volume(s) in question to "P" (Playback) or "R" (record) in the Workspace.

Any idea how to change it in the workspace?

once again thankyou for bringing my drive back to life

Paypal will be visited

kind Regards

Danny

I have no idea what you are talking about now - it sounds like you are referring to some 3rd-party audio application. If so, you should start a new thread about this new problem, giving full details of what you are doing and how you have your system configured, what versions of the software, etc.

I've been following the phantom external drive thread and I have a question for you.

I can only see that I have an external drive from disk utility and it is "grayed out". I click on "mount" and it will not mount. I get an error messge.

It's my understanding that if I can't get the drive to mount in disk utility, then there is no command that I can make in terminal that will restore my external drive so that it appears on my desktop so that I may access it. Is that correct?

You should know that the drive was a recent purchase and I had not yet formatted it for Mac. It still shows that it is a DOS/PC type disk. Still, I had put some files on there that I don't wish to lose.

Is there anything I can do?

I don't know.
What exactly (verbatim) was the error message that you received in Disk Utility?

cabbageandpotato · 01-08-2007, 01:58 PM

The disk “MY FILES” could not be mounted.
Try running First Aid on the disk and then retry mounting.

. . .followed by the this message when I try to repair the disk:

Code:

Verify and Repair disk “MY FILES”
** /dev/disk1s1
** Phase 1 - Read FAT
Unable to read FAT (Input/output error)
Error: The underlying task reported failure on exit


1 non HFS volume checked
	1 volume could not be repaired because of an error

You are a legend!

That doesn't sound good. It would seem like a possible hardware problem with the disk.

You could try using a 3rd-party utility like "Data Rescue" or "FileSalvage" or "Virtual Lab" or the command-line utility 'ddrescue' (google to find them, note also that ddrescue was discussed in an article on the main macosxhints site).

But since the drive is using a Windows format, you might have a bette chance recovering the data with a Windows utility (with the drive connected to a PC).

If the files are of critical importance to you (such that you would be willing to spend a minimum of several hundred dollars to recover them) you should take the drive to a professional data recovery service.

cabbageandpotato · 01-08-2007, 02:31 PM

Okay, thanks!

Could you answer my original question:

It's my understanding that if I can't get a drive to mount in disk utility, then there is no command that I can make in terminal that will restore my external drive so that it appears on my desktop so that I may access it. Is that correct?

cabbageandpotato · 01-08-2007, 03:26 PM

I went to Data Rescue II and I am downloading a demo. Supposedly, the demo will show me the files that it will be able to recover and then I can purchase the product.

According to the information on their web-site, Data Resue II can recover my photos regardless if the drive is PC.

Anyway, the cool thing is that I don't spend my money for the product until I know it is going to recover my family photos.

Not always. It is possible that there is a command-line program/utility that would fix whatever is preventing your drive from mounting.
There are command-line tools that allow fine-grained low-level access to the data on the disk. The trouble is that you need to know how to use them. Disk Utility not mounting your disk is like your car not starting when you turn the key. But a mechanic with the proper tools can go inside the engine and twiddle something to make it work. But mechanics cost money.

cabbageandpotato · 01-10-2007, 09:08 PM

Okay, I got a Data Rescue II demo and it worked. I can recover all my files and then intialize the problem drive and then my ducks should be all in a nice, neat little row. Sound like a plan?

Sounds good - unless of course you suspect that the drive might have failed due to some hardware problem.

cabbageandpotato · 01-22-2007, 02:57 PM

All is right with the universe! I got my files back. I really wasn't too worried because I had a lot of the most important files backed-up on CD. Still, there are a few things that I would have lost.

I hate to sound ungrateful but Data Rescue II amost worked too good. It seems to approach a file from several angles, thus recovering a particular file several times. Now my photos, which numbered just over 1,200, has swelled to over 10,000. Oh, and something else it does is change the file name.

Does anyone understand why this is? Just curious how things work.

Wish me happy sorting!!

Hayne,
Hello, I have a LaCie d2 hard drive extreme, 250 GB. It wont mount to my desktop or through disk utility. However, it is visible in disk utility, but none of the files are accessible. I was hoping you could work the same magic you have with others here. I tried to replicate some of your terminal fixes substituting for the name of my HD, nothing seemed to work, I tried the initial command you gave woodman0682 so I could have something to show, but nothing came up.
my HD is simply 'LaCie Disk'

Thanks!
Michael

Since there is a space in the name, you need to put it all inside quotes.

Try:

ls -l /Volumes
ls -l "/Volumes/LaCie Disk"

I'm positive my disk is called 'LaCie Disk' though, as that is what shows in disk utility. another LaCie name showed up that isn't what my disk is called, but I tried it anyways and it was the same message (substitute new name)...
anything else I should try?
Thanks!
