Hi,
I have a strange problem about external usb hdd :
Dreambox model : 500HD
External USB HDD : 3.5" Seagate expansion 2 TB , with external power supply. NTFS file system.
Image : Newnigma v3.2


I bought a Seagate HDD recently and all my movie collection transferred from old HDD after transferring my all collection , it is connected to DM500HD via USB. In first few hours everything went very well, movies, music vs. played perfectly, live tv recorded as expected. Then I press power button on the remote, dreambox went in to standby. Approximately 8 hours later I returned to my home and want to watch a movie from my new hdd, ofcourse hdd was on sleep mode. I choose mediaplayer from menu, 2-3 sec later hdd start to spin up , root directory of hdd was displayed , I choose film directory WHAT WHAT I was waiting for movie list but it was empty, I tried open music folder , all my music files were ok. Then I tried film folder but it was still empty. I disconnected HDD and connect to my win7 computer , every single movie file was in the film folder. Again I connected the hdd to dreambox, but film folder still empty. From Device Manager of dreambox , unmount hdd then mount it again. SURPRISE movies were in their folder. I was very happy and I thought that it was a temporary problem. But next day I wanted to record a tv program and I adjust timer, when I arrive to home I saw that program didn't recorded and this time recording folder was empty, I looked at the film folder , it was ok. At the and of the a few try I decided that after hdd spinup I can see root directory , but first selected directory becomes empty, while others were ok. I have to say that I downloded seagate utility and I adjusted standby to never for hdd and from dreambox settings I adjusted standby for hdd to 10 min.
I googled and found that some old seagate external hdd has powersave problem with Linux. But this hdd is brand new and I thought that it was ok for linux to.

If anyone can help me it will be very appreciated.
Thanks in advance

Hi,
I googled a bit and find the following link , it is about usb seagate hdd problem with ubuntu.

ubuntuforums.org/showthread.php?t=494673

ofcourse it can not be applied to dreambox directly but it gives some idea and I tried to change some lines :

1. create a fie /etc/udev/rules.d/85-usb-hd-fix.rules
write the following code in to it :


and change the permision of the file 755

2. create a directory /etc/udev/rules.d/scripts
3 create a file /etc/udev/rules.d/scripts/usbhdfix
write the following code in to it




and change the permision of the file 755
(may be this code become smaller but I don't know bash scripting so it is what I can do)

4. restart dreambox.

it is ok for me for 3 days , there is no any problem anymore.

P.S.: You may use the attached files instead of creating files.

Bye

Hi,
After reboot if your hdd didn't recognized by dreambox , and in the Menu - Information remaining free space is wrong (in my case it is -1MB ) please create a swap file on HDD as explained in sparksofinsanity's threat:
Festplatten initialisierung / Probleme
"Extras: large hard disks: For hard drives from 500GB ~ is the create a file system and fsck not easily possible, but the box has enough RAM. Constructing a swap partition or swap files to this need. The simplest approach would be a swap file using the Devciemanager be provided... "


P.S.: picture taken from another threat, it is only for info.
