on my zm computer I have both the operating system and the ZM program at an USB. That meens that the computer boot from the USB.
I Only have the hard drive to save the images. I made this solution to made it easy to restart after a hard disk crash. Everything works good but I have a problem that my USB will broke after about 3 mounths. I have now at least 3-4 broken USBs.

I have read that after a specified number of writings to an USB it will broke.

So my question is if there is something in ZM which write all the time to the USB? For example a logfile or ...........

Hope that someone have a solution

Yes, that's why people don't do this. :)

It's not zoneminder so much, it's everything. Most distros make constant writes through all their log files, temporary files.

Do "lsof|wc -l" on a working linux system and you'll see many hundreds of open files, it's part of a modern operating system.

There are read-only "live" operating systems around - incuding zmarch - which have done work to save these files to a ramdisk and prevent any writes.

Personally, I think you should create a standard install and do it normally. If you are really concerned about disks dying and having to do it again, either keep good backups, or clone the disk when it's all set up, so you can swap in a new disk when you need to.
