What do you mean by "remove"?
The only possible actions within the launchpad notification window are:
- "Warnung ignorieren" (ignore warning),
- "Dashboard öffnen" (open dashboard).
Are you sure, that newer "Sector unreadable on disk" messages (from other disks) will pop-up as an error again in the future, when i press "ignore warning" now?
As you see in my screenshots. The first entry from the list ("Die Option "Ergänzende Informationen aus de...") was a message which i "ignored" by selecting it via the given options mentioned some lines above. This message is still present, but not marked als error. What i don't want/need is that the scanner reports a damage on a other disk in the future, but nobody recognises it, because the warning message is (still) ignored.
As far as i know (from other notifications, e.g. "free disk space low on client computer XYZ") the error messages disappear itself after some amount of time (if the cause/reason is fixed). The message from Stablebit scanner is from 11th of July. We have 16th of July right now and the disk is already dismounted (not present at server).
