How to : Hdd extern + dm 800……

The DM 800 works VERY well with an external disk connected to its USB 2.0 port. At the end of the day, manipulations of the remote control are identical to those with an internal disk or an external disk connected to the eSATA port.

But, in order to get there, you must begin with a bit of tweaking. The following explanation supposes that you are capable of giving Unix/Linux line commands to a Dreambox (See other threads if necessary…)

Enigma 2 pre-supposes that the disk on which you intend to record (or read) movies be mounted on /media/hdd/ and that it itself contains a movie/ subdirectory.

If you already have an eSATA internal or external disk mounted on your DM 800, you must first unmount it:

umount /media/hdd

Then, you must mount the disk connected to the USB 2.0 port in its place:

mount /dev/scsi/host0/bus0/target0/lun0/part1 /media/hdd

(Note that the disk seems to be on a SCSI bus, although this is NOT the case. It’s a rather ordinary Linux trick to emulate a USB bus as a SCSI bus (via the driver) in order to simplify device access for the kernel.)

To make the mount command for your USB disk persistant through reboots, you must modify or add a line to the /etc/fstab file.
If there is already a line meant to mount an eSATA disk that you wish to replace with a USB disk, erase it. It looks like:

/dev/ide/host0/bus0/target0/lun0/part1 /media/hdd auto defaults 0 0

In order to mount the USB disk at boot time, add the following line:

/dev/scsi/host0/bus0/target0/lun0/part1 /media/hdd auto defaults 0 0

The nuance is subtle, but makes a world of difference…
