  • HORM for dummies?

    I'm having som hibernation/resume problems, and was thinking that HORM might be the answer.

    My system has a single 2.5" HDD, with two partitions.
    Can i use HORM on the boot partition without making changes to the 2nd partition? Or do i need 2 drives?

    HORM will work fine regardless of your partition setup.

    What kind of hibernate/resume issues are you having?

      what problems are you having? yes, you can have multiple partitions. however, you need to unmount the other partitions when you hibernate so that the write cache is not saved with the hibernation state.

        Ok, I thought that I needed some kind of write protection that would make my non-system partition useless.


        My system is set to hibernate on ignition off (+ power button & sleep button).
        But the system does a normal boot ~60% of the time, pretty random. There does not seem to be any connection to the off time of the car.

          Is there some where I can find an easy guide to HORM?

            The first thing that comes to mind is that your system isn't completing the hibernation process prior to your power supple cutting off power. But I don't know how your system is set up and exactly what it's doing.

              The PSU is set to 5 sec. to shotdown signal, 45 sec. to hard off.

                That should be enough unless your system is hanging for some reason.

                  I get the screen power from ignition (my battery got drained). So I can't se if the problem is when it writes the hibernation file.

                    I tried lookin into your link, it seems to me that i do infact need EWF to use HORM?

                    All it takes is a simple file called “horm.dat” on the root of your drive. Just create a simple textfile and rename it. When it’s present on the root drive, the EWF NTLDR knows not to reset the hibernation file...

                      I currently have a similar setup where I have the OS on the EWF/HORM partition and my FE(Road Runner)/Winamp on the other.

                      The new carPC is still being bench tested, so I haven't fully enabled/tested EWF/HORM and hibernate/resume w/ my FE yet.

                      After much research, I did it this way to have a stable hib file and so my FE can pick up where it left off, which is read from an ini file that is updated when hibernating. I didn't read/find anything about "unmounting" a partition prior to creating the hib file when using EWF/HORM on another partition.

                      Could you please explain this? I would greatly appreciate it.

                      TIA!

                        yes, you need EWF in order for HORM to work.

                        See my site for instructions for both.

                          I found a problem yesterday that sounds just like that. I use a dinovo mini keyboard. I normally keep it paired with the internal bluetooth so I can keep the dinovo dongle free for my HTPC when needed (2 dinovo's, one dongle). However, I wanted to test it out by using the dinovo dongle kept in. It was plugged into a d-link powered 7 port usb hub. I kept noticing that it would go into hibernation fine, but when I would start up, it would be a cold boot.

                          Found that after it went into hibernation, something with the dongle would wake it back up (probably legacy USB support that I leave on for emergencies). After it came out of hibernation, then it would shutdown cold. Removed the dongle, and everything was yipee skippy again.
                          My opinion is my own.
