UUID keeps changing


Ive got a really annoying problem with a memory card and its UUID, which changes constantly.

Im slotting the card into an external usb card reader.

the UUID's of my usb pen drives are fine (which connect directly to the computer) and always remain the same.

its just this card reader and memory card.

why would a devices UUID change?

Because it has been reformatted?
Because you have used a tool like tune2fs on it?

Tredegar,

I havent reformatted or used any file ststem tools on the card, it just changes UUID every 6/7 shutdowns, its very odd.

Maybe it is something else you are plugging the card into - a camera perhaps?
Perhaps there is something strange about the cardreader - have you tried another type?
Third thought, for my external cardreader I have to plug the card into the reader, then the reader into USB for it to work properly.

Ive only got the one card reader.I dont think its my phone thats affecting the card either, because I cant remember having this problem in the past with Slack 12.

I need to reformat my HD, so Ill reinstall and see if that makes a difference. the one thing I think *may* have influenced it, is that I didnt enable HAL by default on set up. I had to enable it afterwards.

tredegar, you got HAL installed on your distro? I think it should recognise the card once plugged into the reader (while the reader is plugged into the computer). that was a problem I had before, but HAL seems to have solved that for me.

Yes, on kubuntu 8.04.1 I have:
Code:
ps -A | grep hal
 5248 ?        00:00:02 hald
 5315 ?        00:00:00 hald-runner
 5328 ?        00:00:00 hald-addon-inpu
 5345 ?        00:00:00 hald-addon-cpuf
 5346 ?        00:00:00 hald-addon-acpi
 5361 ?        00:00:00 hald-addon-stor
Everything is working as it should
