Talk:How to hotswap Ultrabay devices

HAL script
If the script works, your lshal output should contain something similar to this. In this case the Ultrabay device was a second HDD (/dev/sdb).
Note that in the example, storage.hotpluggable = true while before it was false, so the script worked.

comments
Interesting, especially the support for swap partitions. but I have two comments, first your calling your script hotswap.sh and then having udev call ultrabay.sh?
Then your hard coding the location of the Ultrabay device. This is not guarenteed to be correct, although it will be in most cases. In particular the A and W-series machines. A-series had support for more then one Ultrabay device, while W-series has support for more then one internal HDD in addition to the Ultrabay device, so the Ultrabay location will shift. That is why the Ultrabay Eject script on the main page gets the eject device information from udev.
comments
Hi, thanks, I fix name of script :) Udev calling ultrabay.sh with option -d, so it remove correct device, if you want remove device manualy, is default device useful. But option may be required...
more comments ;)
You might also have a look at the script on the main page, it has a few extra abilities, such as logging to syslog, beeping and putting up popups on the desktop.
Logging to syslog is simple, just call 'logger' with what you want to log. quite should have no effect on this.
For beeps, similar to what windows does you can echo different values to /proc/acpi/ibm/beep, but it only works if sound is not muted. Unfortunately doing so does seem to generate some annoying messages in syslog.
Lastly you can use notify-send to put up messages on the desktop, but before you can do so you have to do an export DISPLAY=:0.0
Syslog and beep
OK, scrip now support syslog and beeping :).
