Finder Error -10810
I don’t normally curse (ok, ok, when writing) but fuck!
Update: I ended up nuking and paving the laptop after grabbing data via target mode. The effort late last year to finally organize my apps, data, and such is paying off. The FileVault image works, and I was able to mount it elsewhere (so I expect to drop it back in the laptop after I finish reinstalling). Eating my own sysadmin dog food: anytime!
Update: Really, a little thinking about the chain of events that may have caused this. Just before the Finder bent itself into oblivion, I just attached my video camera and (gasp!) poked around its file system from the CLI. I had attached the camera before without problems (but this was the first time I sniffed around). I’m not sure this has anything to do, other than folks seem to think this issue is related to external disks.
