Only do this if you have a sdb2:
  • If you have sdb2 which format is it?
  • Script is already there. :wink: In last message go to CODE: SELECT ALL, clck on SELECT ALL, Ctl+C to copy, then go to terminal and paste at the prompt with Shift+Insert.

I only have sda1,sd2 and sdb1. The sda1 and sda1 are Windows 7 and sdb1 is USB (Porteus OS). If I do any downloads I copy to sda2.
Script is already there. :wink: In last message go to CODE: SELECT ALL, clck on SELECT ALL, Ctl+C to copy, then go to terminal and paste at the prompt with Shift+Insert.
Which select all cause there 3 of them?
I just like Slackware because I think it teach you about Linux to build packages where Ubuntu is like Windows you just install programs you want.

@ Jack

As you have specially made a usb for this testing, can you see if you are you able split it into 2 partitions? Use win$oze or linux, whichever easier. Then use win$oze make second partition NTFS?

I will take the USB and try to split it in to 2 partition and format the 2nd partition ext4. If it don't work I will rebuild it. When done I will have a fat32 and ext4 partition.
EDIT:
I had to rebuild another USB. And I haven't ran the script yet. I will wait for you to tell in order what you want me to do.

Jack, when you have the sdb2 set up, make sure mksavfile.sh is in /home/guest directory, then just copy code from here to clipboard

Code: Select all

sh mksavfile.sh  porteussave.dat  256
sudo mkdir /mnt/sdb2/Test
sudo chmod  a+rw  /mnt/sdb2/Test
ls -ld /mnt/sdb2/Test
mv  porteussave.dat  /mnt/sdb2/Test
ls  -lh  /mnt/sdb2/Test/porteussave.dat
ls  -sh  /mnt/sdb2/Test/porteussave.dat
du -h  /mnt/sdb2/Test/porteussave.dat
open a terminal amd paste in at the prompt.

No problem Jack. You are coming along just fine.

Now you can reboot with changes=/dev/sdb2/Test/porteussave.dat. Need to keep on using the changes file until you think there has been plenty of changes gone in. Maybe if you download a small video, 20/30 MB, and check it is still in Downloads after you reboot.

Then
  • Reboot without using changes=
  • Run these commands in terminal

    Code: Select all

    ls  -lh  /mnt/sdb2/Test/porteussave.dat
    ls  -sh  /mnt/sdb2/Test/porteussave.dat
    du -h  /mnt/sdb2/Test/porteussave.dat
    [[ ! -e f ]] && mkdir f;
    mountpoint -q f && umount -f f;
    sudo mount /mnt/sdb2/Test/porteussave.dat f;
    du  -sh  f
    df  -h  f
    sudo umount f; rmdir f
    
Please post all the output, as we are trying to see if we can tell how much of the savefile has been used, and how much is still free to be used. Thanks.

This didn't work changes=/dev/sdb2/Test/porteussave.dat so I change it to changes=/dev/sdb2/Test/porteussave.dat and still it didn't work.

Code: Select all

KERNEL vmlinuz
APPEND initrd=initrd.xz changes=/dev/sdb2/Test/porteussave.dat 3
TEXT HELP
    Run Porteus in text mode and
    start the command prompt only
ENDTEXT
Then this.

FYI Windows doesn't support multiple partitions on removable drives. And FAT & exFAT are better formats for USB drives than NTFS.

Ed, thanks for filling in the gaps in my win$oze knowledge. :)

@ Jack

When you put in the usb, please run these commands:

Code: Select all

file  /mnt/sdb2/Test/porteussave.dat
ls  -lh  /mnt/sdb2/Test/porteussave.dat
ls  -sh  /mnt/sdb2/Test/porteussave.dat

mountpoint -q f && umount -f f;
sudo mount /mnt/sdb2/Test/porteussave.dat f;
du  -sh  f
df  -h  f
sudo umount f; rmdir f
Also can you remember what the error message was that you got when you booted with changes=/dev/sdb2/Test/porteussave.dat?

When I boot up brokenman version it show that is going to use porteussave.dat and save when you shut down. And your don't show anything at all. There was no error it just booted up like it wasn't even there. I wish there was away to do a screen shot or a log file.
EDIT:
This is what mind looks like. And I try it both ways and both way does the same thing.

Code: Select all

    LABEL text

    TEXT HELP
        Run Porteus in text mode and
        start the command prompt only
    ENDTEXT
I'm doing this for you cause I will not use it. I just want to keep it in /mnt/sdb1/porteus/porteussave.dat.
EDIT:2
I can't run this if it don't load porteussave.dat.

Code: Select all

file  /mnt/sdb2/Test/porteussave.dat
ls  -lh  /mnt/sdb2/Test/porteussave.dat
ls  -sh  /mnt/sdb2/Test/porteussave.dat
