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

[thepat20]

Anyone have any idea what to do with my situation?

[crstokes83]

Hi guys, really sorry about this, but I have pretty much the same problem as above... Trouble is I don't appear to be savvy enough to adapt the solutions above to my own system.

I have tried to get my head around the above suggestions, but I must be doing something wrong as I can't seem to get any results.

My problem is:
I tried creating a new folder inside my external hard drive when I realised I didn't have permission to do so (which is odd to begin with, but probably not important). So I tried to change permissions on my drive (for some reason set to another user who is not admin) back tomyself (admin) only to find the drive has now vanished!
It doesn't show up on the desktop of any user, but does show up in disk utility. However the option to repair permissions is not available, and all other options are fruitless.
I need a hero!
I'm running OS 10.4.11, the drive is an external USB 2 drive named "Va Voom Drive". As I pretty much use the Mac for Adobe apps, this side of things is all very new to me and I feel way out ofmy depth reading up above.
Also, I can't remember the paths or exact names of any files on the drive so had real trouble with a couple of the suggestions above

Can any one help?

Thank you very much in advance!!

Hi guys,

Here is my situation. Got a lacie d2 300 gb with triple interface, and it had previously been formatted for PC, which I erased, set up with time machine (it made one volume called "backup") but now all of a sudden it doesn't appear on the desktop, and in disk utility the volume "backup" is grayed out. Sometimes when I try to repair it just gives me a generic error message, other times it says input/output error. I can't mount it, nor can I repair it or verify it.

I tried to check it out in terminal, and i looked under "Backup," the name of the disk which was "WDC WD2500JB-00REA0 Media" and the disk identifier, which is "disk1" and which sometimes shows up instead of "Backup" as the grayed out volume in disk utility.

In terminal (note that i messed up a couple of times... sorry) none of these three can be found, even though the HD is right there in the disk utility... and I don't seem to even be getting the "Welcome to Darwin" language everyone else is...

Help! I don't care about what's on the disk and would be happy to erase and be able to start over somehow. Sorry if this question is totally infantile.

Thanks!

Also, I forget to mention that this is the info the hard drive gives:

Partition Map Scheme : GUID Partition Table
Disk Identifier : disk1
Media Name : WDC WD2500JB-00REA0 Media
Media Type : Generic
Connection Bus : USB
USB Serial Number : 10000E000C7EC57E

Partition Number : 0

Now the one volume on my HD is appearing as "disk1s2" - HELP!!!

Hi folks,

Seems like I'm having similar issues trying to get my brother-in-law's HD working again. I'm no expert, so I was wondering if anyone here might have an idea? I am logged in as the root user and I got the following info from Terminal. The drive (disk0s2 ) is not mounting under Disk Utility, and it says it is "Unable to read FAT partition input/output error"

Etherington:~ root# ls -l /Volumes
total 8
lrwxr-xr-x 1 root admin 1 Nov 26 10:56 Macintosh HD -> /
Etherington:~ root# df -h

map -hosts 0Bi 0Bi 0Bi 100% /net
map auto_home 0Bi 0Bi 0Bi 100% /home
Etherington:~ root# echo "done"

Mucho thanks in advance for any advice!

That doesn't sound like a permissions problem (the topic of this thread).

I/O errors usually indicate a hardware problem with the drive.

Hi everyone,
i have a little problem.
I have an external Hd with two partitions. One is a Fat the other is a hsf+.
Everything was working fine but today after i finished to backup my whole system on the hfs partition (which contains also another folder) when i replugged the ext disk in, the fat partition icon appeared as usual on the desktop, the hfs partition didnt.
Im sure both partitions are mounted because if i ask finder to show hidden files both partitions are on the desktop (but not on the finder window side bar which contains only the FAT one).
Pretty much:
2 partition: FAT and MemUp
inside MemUp a DATA folder and all the system copied folders [like Applications, Desktop DB, Desktop DF, Developer, Library, Network, System, Users, Volumes, automount, bin, cores, dev, and so on].
So i created a new folder "SystemCopy" and i put everything but DATA inside it.
I had to do it through terminal because hidden files didnt get selected with Apple-A.
Before this move action i guess everything was still ok.

Now in my MemUp partition i have two folders. DATA and SystemCopy.

drwxrwxrwx 1 chiapil chiapil 32768 Nov 26 17:45 FAT3
drwxrwxrwx 7 chiapil chiapil 340 Nov 26 19:16 MemUP

drwxrwxrwx 23 chiapil chiapil 782 Nov 25 19:18 DATA

Does anyone know hot to have my MemUp Partition not hidden aka back on my desktop?

[metherington48]

OK - any solutions for this kind of thing? It won't repair in Disk Utility, but you can see the drive (it just won't mount).

Seems like the FAT partition got messed up when the power went out on the hard drive, and it didn't unmount the right way.

It seems like that would be a software issue(?)

Thanks for any other tips you could give...

If the problem is a corrupted filesystem, then that's a software issue and since the filesystem in question is in FAT format, I'd recommend using a filesystem repair tool in Windows since FAT is a Windows format and hence the tools for it are more sophisticated on Windows.

But if the error messages are I/O errors, that usually indicates a hardware problem - maybe the drive was close to failure and the power outage pushed it over the edge.

In any case, I repeat that this doesn't seem to be a permissions problem (the topic of this thread).

[chiapil]

Just to let you guys know, there is a utility - SetFile (stored in /Developer/Tools, thus included in Xcode) which set the invisible extended attribute on folders.

I messed with my permissions and access yesterday to find out today nothing is accessible on my external firewire drive. It does show up in disk utility. I did enter the code in terminal and this is what I got :

Hi, ur combination (d------r-x) is def pretty weird ....
Just try with

chmod 777 /Volumes/DJL AUDIO

(I'm Running Leopard on MBP and i just did a Repair Disk to the External)
I was making an Automator Application that would Eject my External Drive at the end of it's program. When I went into Disk Utility to remount the drive after my test worked nothing showed up on the desktop.

Disk Utility says it's mounted √.
I can Access it via Cmd-G (/Volumes/External Drive) √.

However it has a funny icon, doesn't show up on the desktop anymore or the sidebar on finder windows and does not show in the Main root directory (where Macintosh HD and Network reside not the same as /volumes)

Would appreciate any advice.

Here's some photos for reference
1. Info of disappeared Disk



2. Diskutility (mounted)



3. Drive works (I can see folders)

[redworm]

i had a similar problem,
I made a task in Automator in which my External Drive would eject at the end of the task, however after the first run I wasn't able to see it on the desktop anymore:

after an hour on the phone with an apple tech agent that did not know much about computers, i was fortunate enough to speak with a specialist who gave me a legitimate solution:

"sudo chflags nohidden (PATH)"

Hi everyone,

I'm a music producer and i've just bought a new 8 core mac pro. It's OSX 10.5.4 on it. Basically it's somehow locked me out of my external lacie hard drives and they are my entire life's work! I've managed to log in a 'root' admin to be able to explore the drives which is a relief, but they're still showing up as locked and the 'get info' permission altering and disk utility from installation disk won't fix the problem.. I'm honestly at my wits end so any help would be unbelievably gratefully received..

Many thanks in advance..

James

Read the suggestions in this older thread and do what seems appropriate for your drive:
http://forums.macosxhints.com/showthread.php?t=44391
The basic idea is to use 'sudo chmod' to add appropriate permissions to the top-level folder in your drive.
Note that if the name of your drive contains spaces or quotation marks etc, you will need to enclode the drive name in double quotes.

Hi everyone, i've just got an 8 core mac pro and i've got 3 lacie 300gb external hard drives containing my life's work. I applied read and write access to all enclosed items under Macintosh HD and then the computer failed to load. After painful advice from an apple technician, i reinstalled Mac OSX with an erase and install.

After loading it up, i went to open my external hard drives but they wouldn't open. It comes up sayig "you do not have sufficient access privileges". They all have a little lock icon on the bottom left of the Lacie icon. I've tried disk utilty but no luck (even from the installation disk). I've tried 'get info' but it just says that there's "custom access" in the permissions bit and it won't let me change them. I've tried a lot of the code on this thread but terminal keeps coming up with "operation not permitted"..

Please, please, please help as it's literally my life's work and i'm at my wits end.

Many thanks in advance,

James

[jimbo777]

Hey thanks for the quick response, i've actually posted on that thread with more info. None of the commands seem to work and i've copied and pasted them, being as meticulous as possible.. It comes up as 'operation not permitted'.. Also, under 'get info' it says that there is custom access ad it won't let me change that..

[hayne]

jimbo777:
I merged your new thread with this existing one so it is all together.

Please show us (by copy/pasting the contents of the Terminal window) what commands you are issuing and their results instead of telling us about them.

Be sure to show us the results of the following:

ls -aOle "/Volumes/name_of_your_disk"

And tell us what version of OS X you have (I'm guessing Leopard (10.5))

[jimbo777]

Thanks so much Hayne..
