Dreambox 7000 harddisk problem

which file system? how many partitions? if you telnet the dreambox can you see the hard disk?

I don't think your hard disk is formatted ntfs because enigma run on linux system, and ntfs is for windows.
Telnet your 400 s and execute the mount command you'll see something like this:
/etc > mount
/dev/root on / type squashfs (ro)
none on /dev type devfs (rw)
none on /sys type sysfs (rw)
/proc on /proc type proc (rw)
devpts on /dev/pts type devpts (rw)
/dev/mtdblock/1 on /var type jffs2 (rw)
none on /tmp type ramfs (rw)
usbfs on /proc/bus/usb type usbfs (rw)
/dev/scsi/host0/bus0/target0/lun0/part1 on /mnt/usb type ext3 (rw,data=ordered)
/dev/ide/host0/bus0/target0/lun0/part1 on /hdd type ext3 (rw,data=ordered)
/dev on /dev type devfs (rw)
none on /sys type sysfs (rw)
/proc on /proc type proc (rw)
devpts on /dev/pts type devpts (rw)
none on /tmp type ramfs (rw)
usbfs on /proc/bus/usb type usbfs (rw)
/dev/scsi/host0/bus0/target0/lun0/part1 on /mnt/usb type ext3 (rw,data=ordered)
/dev/ide/host0/bus0/target0/lun0/part1 on /hdd type ext3 (rw,data=ordered)

The last line represent the mount point of the hard disk on my ipbox 350, as you can see is type ext3.
The first think to do is:
umount /hdd
fsck.ext3 /dev/ide/host0/bus0/target0/lun0/part1
at the end you have to remount the hard disk with:
mount /dev/ide/host0/bus0/target0/lun0/part1 /hdd
and try if work.
May be you have a different fs like reiserfs or jfs, or different device like /dev/hda so pay attention, but the procedure is the same.
I hope this help you.
