becky-cookie;
OK, got you about the cleanmgr utility, scandisk is a somewhat different utility.
What I'm suggesting is to either modify the setting for the number of days that go by without accessing a particular file before it's compressed, which is one of the Options for Compress old files. That Options button will show up if you single click (and thereby select) "Compress old files" when running cleanmgr. By doing that any file would have to age twice as long before it was selected for compression, but there is no hard and fast rule how long that should be, so you could potentially avoid a file that's giving you problems. An even stronger work-around would be to uncheck "Compress old files" so that no files are ever compressed and the hanging step is totally bypassed. Unless you're tight on disk space, compression is probably un-necessary.
All this is assuming you're hung in the step "Compress old files", which is why I asked that you note the amount of space before and after a compression was attempted, so you could tell if all files were actually being compressed (a report of zero KB space available to be saved after compression) or if it was hanging in that step and not completing it (more than zero KB reported as recoverable). The main point to be aware of is that OneCare uses the Cleanmgr utility to do its disk clean-up, so the options/settings that have been set in Cleanmgr are also the settings that OneCare will use when it runs its own tune-up.
