Permission Denied On USB Hard Drive

[krishna.murphy]

I'm trying to move some .jpg & .mp3 files from a USB hard drive that is formatted under MAC OSX (0xaf) to a Windows Vista Laptop.

I am using a Knoppix 6 live cd. Knoppix sees the laptop hard drive as

System /media/sda2
Vista /media/sda3
Recovery /media/sda1

and the USB hard drive as

disk2s1

I can see files on the laptop's hard drive but when I try to access the USB drive I get 'Permission Denied'

Can the files on this drive be transferred to the laptop?

Thanks for any help or suggestions

Have you tried

ls -la disk2s1

to get more information (owner, etc.), or sudo to make your requests with root permissions?

Cheers!

Hi

All I get is: ls cannot access disk2s1 no such file or directory

Hi

Okay, try this:

locate disk2s1

That should tell you where it is, I think. The MacOS disk format seems to be pretty challenging for other OSs...

Hi

Now I get this:

locate:warning:database '/var/cache/locate/locaedb' is more than 8 days old (actual age is 61.0days)

I think that "disk2s1" is the partition's label. Usually the partition gets a mount point in the directory /media and that mount point is named after the device name. In the PCMan File Manager the partitions are often identified by their label. You might try

ls -l /dev/disk/by-label/disk2s1

to get the device name. Execution of the command

mount

delivers information about the partition's mount point if it's already mounted. Afterwards you might execute

ls -la "mount point"

Example: The partition has got the label "Cruzer1" and the device name is /dev/sda1. The mount command delivers the mount point /media/sda1. Thus I would execute

ls -la /media/sda1

in order to see the owner, group and permissions.

If the partition has not yet been mounted then the mount command won't show you a mount point, but
you might try

sudo mkdir /media/macdisk
sudo mount -o gid=1000,uid=1000 /dev/disk/by-label/disk2s1 /media/macdisk
ls -la /media/disk2s1

If this does not work then mount will give you an error message.

sage: mount -V : print version
mount -h : print this help
mount : list mounted filesystems
mount -l : idem, including volume labels
So far the informational part. Next the mounting.
The command is `mount [-t fstype] something somewhere'.
Details found in /etc/fstab may be omitted.
mount -a [-t|-O] ... : mount all stuff from /etc/fstab
mount device : mount device at the known place
mount directory : mount known device here
mount -t type dev dir : ordinary mount command
Note that one does not really mount a device, one mounts
a filesystem (of the given type) found on the device.
One can also mount an already visible directory tree elsewhere:
mount --bind olddir newdir
or move a subtree:
mount --move olddir newdir
One can change the type of mount containing the directory dir:
mount --make-shared dir
mount --make-slave dir
mount --make-private dir
mount --make-unbindable dir
One can change the type of all the mounts in a mount subtree
containing the directory dir:
mount --make-rshared dir
mount --make-rslave dir
mount --make-rprivate dir
mount --make-runbindable dir
A device can be given by name, say /dev/hda1 or /dev/cdrom,
or by label, using -L label or by uuid, using -U uuid .
Other options: [-nfFrsvw] [-o options] [-p passwdfd].
For many more details, say man 8 mount .



I still get 'Permission Denied' when I try to access the disk. I can mount and un-mount by right clicking the drive.
