RetroISA process prevents unmounting of drives

[macpro]

Whenever I mount a physical disk to my Mac, I cannot unmount it anymore.

It shows a message that the disk is in use by another process.

I can force remove it if I want, but that's not a nice option, so I don't.

 

Found out that RetroISA is the process that is accessing this drive.

Don't know why it is, but if I stop RetroISA using activity monitor, I can safely remove the drive as wanted.

 

I'm running Retrospect client 11.5.0 (137) but this happens with earlier versions too.

Clients are Macs with 10.8 thru 10.10.

If you want to avoid this issue, you can turn off instant scan in the Retrospect engine preference pane.

Thanks for the work around, but that's not really a solution for this problem.

I found that identifying volumes to exclude in the Retrospect Client Privacy tab in System Preferences seems to help with this situation. I typically add similar exclusions in Spotlight and Time Machine System Preferences, where appropriate.

Thanks, that's a nice tip. I'll give that a try, although I'm positive it will not make me happy.

It's all about occasionally connecting a drive to my Mac and thats most of the time a drive that wasn't connected before.

So I would have to do that every time.

 

I'd rather have Retrospect not touch my external drives unless I explicitly use them in backup jobs on the server.
