Version: (using KDE 4.3.0) Installed from: Ubuntu Packages The hard disc system monitor seems to keep an inital partition list persistent forever. I shuffled around my hard discs, meaning I swapped two (sda and sdb) and added a third (sdc). However the applet doesn't reflect that. It still shows the old partition list i.e. it has those that used to be sda still as sda even though they are sdb by now, and the new ones from sdc don't show up at all.

Ok, I'll reopen the bug, I've found this bug already reported but, like you've wrote on bug #202721, it wasn't that, probably I've had pasted the wrong bug id... now the problem is to find again the other bug :-)
Plugged in memory stick and it shows in hard disk configuration dialog.
I disagree with marking this as resolved... Pluggin in USB sticks and having it show up in the config has never been a problem for me, too! The problem seems rather when the partitions of a disc change. Then the old data is kept and not properly updated. What makes it more confusing is that this doesn't happen always when partitions on the disc change. As I wrote, I shuffled around and reformatted my discs. And somewhere in between I noticed this problem. However, by now everything seems fine i.e. the list in the config dialog reflects reality. Well, except for one partition (I'm not sure if this is the same problem. I wouldn't be surprised though): My windows partition on /dev/sda1. It's labeled "WindowsXP". And the config of the hard disk monitor used to show that label. At some point, when shuffling around the discs, a different partition on a different disc became sda1 and the entry changed to "/dev/sda1" (it was an ext3 partition with no label IIRC). Now the original disc with the "WindowsXP" labeled partition is sda1 again. However: the entry is still "/dev/sda1". It has not been updated.
Since hard disk monitor seems to update in partition changes (USB etc.) I'm not sure if this is a bug is in hdd monitor or somewhere deeper, but it's now reopened.
I'd even try it out again, the problem is, I don't have a spare SATA disc atm. ... I also wondered, whether the problem might actually be on a lower level. But I still think there might be something wrong, how the applet handles the partition list. I never saw any problems with the device list in Dolphin for example (IIRC). As for the sda1 problem for instance, I just noticed these two entries in plasma-desktop-appletrc: /org/freedesktop/Hal/devices/volume_uuid_1CF4_2041=/dev/sda1 (not accessible) [...] /org/freedesktop/Hal/devices/volume_uuid_1CF4_2041_0=WindowsXP (not accessible) [...] When I remove these entries and restart plasma I get: /org/freedesktop/Hal/devices/volume_uuid_1CF4_2041=WindowsXP (No idea where this _0 one comes from) But at some point this "/dev/sda" slipped in for 1CF4_2041, and now it's there forever (or until I removed it). No idea how this uuid list is handled internally... But what happens if a partition has disappeared after reboot (i.e. there is no live event plasma or whoever could pick up), but is still referenced in the plasma config? Is is checked and removed? As for a while I had ghost partitions in the hard disk config partition list, which didn't exists in reality anymore. So somehow there haven't been removed from the list... Also what happens when a different partition with a different uuid appears, but with the same name e.g. /dev/sdb1?
Yes, I think I know whats goes wrong here. Applet has user editable name for partition. If uuid has not name yet, it tries to guess it from device label, mount path and device name. If same uuid is seen as another device label stays the same (but user can edit it in config dialog). Maybe if label starts with "/dev/" it should try to guess it again...

I can manually edit the label??... Indeed! :) I think that should be made a bit more discoverable... ;) Anyway, what about the following case? Applet reads in a label from the device, in my case "WindowsXP". Then the label is changed (not in the applet config dialog, but with some file system tool). Then I'd expect the applet (config) to reflect that and automatically show the changed label, as long as I haven't changed the label in the config by hand. So IMHO the manually set/changed label should be saved separately. If empty, the applet shows the label extracted from the device. On every system start the extracted label is checked, whether it has changed or not. Or maybe don't save them at all, and on every startup read all the labels from the devices and show them. And in the config only save the uuid and a possible manually set label. Anyway, this seems indeed to be a different problem than the original one of the report, and thus the original problem is still not fixed... I'd say ;) I'll see if I get a disc to reproduce it... Oh, and thanks for working on this non the less! :)

So you'd have to save them both, the extracted and the manually set label.

This bug has been marked RESOLVED but I am still facing problem with system monitor-hard disk widget. I am not sure if it is a problem with the widget or with solid, but the same problem I found with my fiend running KDE trunk. I have attached snapshots before and after mounting my USB drive. What happens is, when I first insert the USB drive (not mounted), system monitor-hard disk settings shows the device inaccessible. But when I mount the device, the same system monitor-hard disk settings does not show any option for my USB drive. What might be wrong?
