Very odd hidden harddrive problem

Ok, there is no need to type "ls /Volumes/Untitled" again, but try typing this in exactly:

ls "/Volumes/UNTITLED 1"

Not just what's in the quotes, but the whole line, including ls
 
"JulianCS:~ Julian$ ls "/Volumes/UNTITLED 1"
$RECYCLE.BIN New Mac
Call of Duty2(PELTIE) Planet Earth
Games Salvage Sunday, 9 August 2009
Logo Salvage Sunday, 9 August 2009 1
Metal Trip Movies Windows 7 Beta 64-bit.pdf
New Folder Windows Apps
JulianCS:~ Julian$
"

Just the folders on my external harddrive - not the 1TB one, my other one.
 
Oh, well disconnect that one. It's only going to make this more confusing. Run "diskutil list" again and "ls -l /Volumes/" with ONLY the external drive in question connected.
 
JulianCS:~ Julian$ ls -l /Volumes/
total 24
drwxrwxr-x 6 Julian staff 272 9 Aug 20:00 1TB
lrwxr-xr-x 1 root admin 1 8 Aug 18:10 Macintosh HD -> /
drwxr-xr-x 1 Julian staff 8192 8 Aug 17:01 Untitled


that last untitled is a windows partition - part of the internal drive, can't eject.
 
Its hard to imagine it was all deleted, because there was no hitch, or performance drop of any kind - surely it cant delete ~700GB in a split second? You mentioned earlier that we deleted the 1TB 1, but we typed in 1TB into the deletion command..

Well nothing was deleted from the external drive. It was disconnected when we ran the deletion command, so it's impossible for it to have been touched. Frankly I'm befuddled. The only last thing to try is to perhaps try making another mount point and manually mounting it to that. If that doesn't work then I don't know what to tell you.

Tell me the output of "diskutil list" one last time.
 
Thanks for sticking around, by the way.

Go into disk utility, select the external drive, and click "Unmount." Then open up a terminal window, and type the following command sequence:

cd ~/Desktop
mkdir testmount
sudo mount /dev/disk1s2 -t hfs ~/Desktop/testmount
ls ~/Desktop/testmount/

I think I got the syntax correct, but let me know if it doesn't work and the output either way.
 
"JulianCS:~ Julian$ cd ~/Desktop
JulianCS:Desktop Julian$ mkdir testmount
JulianCS:Desktop Julian$ sudo mount /dev/disk1s2 -t hfs ~/Desktop/testmount

usage: mount [-dfruvw] [-o options] [-t ufs | external_type] special node
mount [-adfruvw] [-t ufs | external_type]
mount [-dfruvw] special | node
JulianCS:Desktop Julian$
"

:confused:
 
Oh I screwed up the order. Try "sudo mount -t hfs /dev/disk1s2 ~/Desktop/testmount" instead.

Edit: followed by "ls ~/Desktop/testmount/"
 
ok, it showed up on the desktop. doubled clicked it, and it was empty, then upon closing it dissapeared.
 
Ok that tells us that the mount is fine that OS X is creating when the drive is connected. At this point you can type in "umount -f ~/Desktop/testmount" and then disconnect the drive. Then go ahead and put the "testmount" folder that's on the desktop in the trash. I'm not sure what's going on and what happened to the data. The only thing I can suggest to do is to run data recovery software on the external drive, after reconnecting it so OS X will make a new mount point in the "Volumes" folder. Don't save any new files or do anything at all with the external drive until you've run data recovery software on it. I'm sorry that I'm unable to help you further but I really do not know what is going on.
 
Right, did a restart and everything is the same. My problem now is that I don't have enough space for the data recovery software to dump the recovered files. It's finding stuff ok, but nothing is named. Anyway, going to be a long night I suppose.I'm gutted. But thanks very much for helping me this far.
 
Ouch! That's a lot of data to lose. Just to back up BillG, from glancing over this thread it looks like everything was done right - this shouldn't have happened.

Try using Disk Utility to verify both disks (Internal and your 1TB) and then more importantly, verify permissions on the drives.
 
Verified fine, and the permissions is greyed out.

About last 10 years of photos, every single music recording I've ever done (I am a musician). All music, Games (~10), Films (~250), TV shows etc... The music is on my iPod so I'll use Senuti on it. Hopefully I'll be able to recover the pictures, and then I'll cut my losses.

Im Sorry for your loss, it happens to the best of us.

In order to fail proof your important data, i suggest making multiple backups of it by priority, i have an external hard drive with all important stuff on it, but the most important stuff i burn onto special dvd's that i store in my airtight vault... best thing in times of drive failures.

Never rely on Internet Hosting/Backups/Storage.

And never rely solely on external drives.
