How do you re-mount a hard disk

[Willowman]

I have had a hard disk in my DM7000 since I bought it new 3 years ago. It has worked without problems. After playing around with a compact flash memory card I can no longer access the hard disk. I am using the latest PLI Helenite image. If I access the system and hardware settings I can't find the menu option to check the mounts. On the same screen as the red format button there is a yellow button to give disk status. It reports unknown file system. The disk is 78% full and I think the file structure is still in place. How do I remount it. The usb stick is still working ok.

In the web interface there is a mount manager which lists the following see below. Should all of these be mounted? There is a red cross to left of each row. Some of them appear to be duplicates. Before I make the situation worse some advice would be welcome please. Thanks

Having searched through other sections of this board I now think this problem is down to a bug in Enigma which does not allow the simultaneous use of compact flash and a hard disk. Inserting the compact flash has disabled access to the existing file structure.

The question is has it permanently destroyed the file structure on the disk?

I can reformat the disk but I would prefer to recover my movies.

Note to moderator - As this is now a general Dreambox question I will copy the original post to a more widely read forum

Power down your dreambox.
Remove the CF, let the HDD be.
Start your box, and see what happens.
If you're lucky, all is still there.
You could try and see if you're hdd is set as slave before re-inserting your CF.
It must be slave, otherwise it will never work.
There seems to be a hardware mod by removing some pins in the CF slot, but i don't know if that can solve these things.

I've tried that and it didn't work. I am not familiar with Linux to know how to it at the system level. On a PC there are many ways you can recover the directory and file structure on a disk.

telnet to the box, login and type this:

mount /dev/ide/host0/bus0/target0/lun0/part1 /hdd

see what error message it returns.

Hi,

It happened the same to me some months ago (trying to use a CF).

Some CF are not compatible with Dream + HD (many forums discuss the reasons of this… )

Trying to use a CF destroyed the structure of the HD…

What I did…?

I don’t remember the commands (search linux, commands… google)… but at the end I was able to read the data again… but some data was missing… (ex. file that contains the info of the recorded movies..) and I finished re-formatting the HD…

Now I am using HD and CF and USB…. Try to find an old CF (in my case of 512 M) … some one works… others not.

If you are able to read the data again… you will need a second HD in order to copy files (!!!!) and after that format the HD and restore the files…

Good luck

Thanks robb it returns

Can't find /dev/ide/host0/bus0/target0/lun0/part1 /hdd in etc/fstab

If I FTP to the Dreambox and look in etc fstab appears to be empty 0 bytes
the hdd folder is there but it only contains an empty log folder

Thanks picc2001 my knowledge of Linux is very limited. I will investigate linux commands to try to gain access to the disk. I have plenty of storage on my home network to backup as much as I can retrieve when I can see anything on the disk.
The stupid thing was that I don't really need to use CF. I happened to discover a CF stick and tried to install it. I didn't expect this hassle.

[Willowman]

Luckily for me the only thing on the hard disk are movies as everything else is on my USB stick.

It looks like I need to rebuild fstab which I believe is just a text file. Assuming that there is no backup copy of it anywhere on the DM7000 what is the best way to do this?

Could someone with a DM7000 post the contents of their fstab as it would give me a start.

What I don't want to do is lose the content on the USB although I have Flashwizard backups of the boot images on an external PC.

[robb]

It is normal that /etc/fstab is just a 0-byte file. It amazes me that mount is complaining about this.
I think normally mount will just do what you ask when trying to mount with 2 parameters (like I explained). The fstab is just for shortcuts like "mount /hdd".

You could try giving the filesystem type, like this:
mount -t ext3 /dev/ide/host0/bus0/target0/lun0/part1 /hdd

When that does not work, make sure you have swapspace (on your USB stick) and issue this command:
fsck.ext3 /dev/ide/host0/bus0/target0/lun0/part1

This will attempt to repair the disk. It will take quite some time, especially when the disk is large.

All of the above assumes that your disk is formatted in ext3. If you have formatted it long ago, it could be reiserfs and you need to specify the word reiserfs instead of ext3.
Do you remember if it was reiserfs? if so, for the past couple of PLi images you needed to download a separate module for reiserfs support. When that was not required, it should be ext3.


Don't panic yet, there probably is only a minor error somewhere and it can only be made worse by panic.
When you have a spare PC (aside from your system with lots of storage) you could put the disk in there, boot it from a knoppix CD, and mount the disk there.
Then you can copy the files over the network.
But I would only do that if all else fails, as you need to open the box and remove the disk. Should not be required.
