Finding the Unix path of a firewire drive

I was wanting to do some experimenting and to do that I need to know the Unix path of a firewire drive. Is there an easy way to do that?

Ok I'm trying to do that but dir does not work, when I try cd /volumes/"the name of the drive" it reports that no such volume exists.

So I guess my question is how exactly do I look into /Volumes?

The filesystem is case sensitive... "Volumes" is not the same as "volumes". Try "cd /Volumes".

Computer:~ $ cd /Volumes
Computer:/Volumes $ /Zee Disk
-bash: /Zee: No such file or directory
Computer:/Volumes $ dir
-bash: dir: command not found
Computer:/Volumes $ cd /Volumes/Zee Disk
-bash: cd: /Volumes/Zee: No such file or directory
Computer:/Volumes $

This is what I tried but can't get past this point/

You have to quote (or escape) any volume name with a space in it...

On my system:

cd /Volumes/Macintosh\\ HD

or

cd "/Volumes/Macintosh HD"

'ls' is the command for getting a directory listing.

You can also use the mount command.

OK, attempting to use with dd gets me this:

dd bs=512x8 if=/Volumes/Zee\\ Disk/Movies of=/Volumes/disk\\2
dd: /Volumes/Zee Disk/Movies: Is a directory
0+0 records in
0+0 records out
0 bytes transferred in 0.005186 secs (0 bytes/sec)

Movies is actually a file, and I tried to copy the whole disk.

What are you trying to do? Backup an entire disk? 'dd' isn't the right tool.

I use rsync for backups (tar and 'cp -r' would probably do as well), but if you're not comfortable at a shell prompt, I would recommend any one of the many backup utilities available on OS X.

No I'm trying to backup a working disk to prove that dd works but in the future I want to use it to copy a damaged HD.

Fair enough.

just as a word of warning, don't expect the process to be as simple or cut-and-dry as the note seems to indicate. Chances are when the disk is dead, nothing is going to help including 'dd'. Typically, dead disks are not readable.

Keep good backups and then you won't have to worry about trying to recover data on a failed disk.

This works if I go file by file, but the output is not visible.

dd bs=512x8 if=/Volumes/Zee\\ Disk/ of=/Disk\\2/foo.dmg
dd: /Disk2/foo.dmg: Not a directory

If I go straight to Disk2 then no problem other than I cannot see the file. If I call the output file "foo.dmg" I get the above error. Not a directory

I have tried to send it to Disk 2.dmg but I cannot see that image.

Do you have a folder "/Disk2" or did you mean something else?

Wouldn't that be mounted under "/Volumes/Disk 2" and not "/Disk2"?

That's it, sorry I thought that I tried that, already. I think that I tried /volumes, instead of /Volumes. The output is foo.dmg which is as it is supposed to be but I cannot mount the image.

dd bs=512x1000 if=/Volumes/Zee\\ Disk/Movie.mp4 of=/Volumes/Disk\\ 2/foo.dmg
2275+1 records in
2275+1 records out
1165063033 bytes transferred in 69.536074 secs (16754800 bytes/sec)

Ty

edit: OK it is not a disk image, if I output to foo.mp4 everything is fine, but I should be able to copy the whole disk or at least a folder, does anybody know how to do that??

You cannot use dd to backup folders, you use it for backing up entire partitions (as the document you quoted explains).

I found the 'if' and 'of' paths by using df -h, all works well.

You can get the full unix path to anything by dragging its icon into a Terminal window.

(Except sidebar items - so use the alternatives such as the proxy icon in the titlebar when the drive is selected, the desktop icon if you have it set to show, or go up in the "paths" list in the Finder and drag the Firewire drive's icon.)

As "ThinkingDifferent" mentioned previously, "mount" works as well for showing where volumes are mounted.

FYI: You can also find the UNIX firewire Mount Point in the System profile.

Some Unix commands want a device or file path and yet others or for other reasons you may want a directory or folder path. df -h gives you both.
