[Solved] USB Fat32 persistence

Post#1 by setsquard » 08 Feb 2016, 16:42

I have got my usb drive which is formated to ext3 working fine now with your help but a friend wants me to do one for him on a fat32 drive
I have read the [HOWTO] Create a save.dat container
http://www.porteus.org/component/conten ... d-one.html

and saved a "save.dat" container to /mnt/sdb1/porteus/
but i have 4 lines starting with APPEND it does give an example which should be used and where on the line,
changes=/porteus/save.dat should be placed
I have tried with and without "changes=" at the end,as it says, but it does not work

so could someone please the edit my append line below so it will work
LABEL XFCE
MENU LABEL Graphics mode (XFCE)
KERNEL vmlinuz
APPEND initrd=initrd.xz changes=/porteus timezone=Europe/London kmap=gb,us


Thanks

As long as someone more knowledgeable does not come along, try

Code: Select all

Now that we have cleared that up lets move to your choice of ext3

http://www.flashbay.com.au/blog/usb-life-expectancy

Some people get so excited by this write cycle lifetime they insist you choose ext2 as the format. I too am anal but take the big picture that usb stick only cost about $5-10 so prefer to format it as ext4.

In other words it does not hurt to have 2 sticks the same, if you can afford it.

However you seem to be forgetting Murphy's Law. At end of shortened life-cycle could be several vital files on stick, and it decides to break down. Or worse still, these files could get nicely corrupted in innocuous places, so nothing gets noticed until corruption irreversible. This then means you have no idea at which point in time it started, and absolutely no possibility of a rollback. :evil:

Best to be safe than sorry, and reduce as much as possible probability of such an eventuality. 8)

Do people back up important flles to USB stick?

Do people really back up only once?

Actually no to both questions. People store their work assignments on the USB stick, their homework, their birthday pictures and other special memories knowing that should the pc die or be stolen their important files will be on the USB stick. The fact that the USB drive may die never enters their mind. And backups, nobody backups up files, the pc takes care of all that for them. At least that's what they believe.

These opinions change when the USB drive goes thru the 2nd washing machine cycle, is lost on the train/plane, when they forget the password they assigned to the drive, etc.

:wink:
