My 2011 Mac Mini recently started acting up. I posted bountiful details of the problems in this thread in the MM section, but the short story is that the Mac wouldn't recognize either my OS X or my Bootcamp partitions as bootable startup volumes. If I booted from my external backup OS X HDD, though, I could see that all the data was intact & copyable. I first thought disk failure, but stumbled on some isolated reports of the Paragon HFS+ and NTFS drivers causing exactly these kinds of problems. I had just installed the Paragon drivers (free with a Seagate HDD, gee thanks!) right before the Mini started acting up, so I'm strongly suspicious that's the real culprit. I think the HFS+ driver in particular messes with the Master Boot Record, or some other part of the partition needed to show the volumes as bootable. Does anyone have any ideas how to use Terminal or something else for an easy fix to undo these issues? Folks in this thread seemed to have had some success in similar cases, but not necessarily with Paragon. If I install the NFTS driver on my backup drive (shudder), I might be able to delete the HFS+ driver from the Bootcamp partition, but not sure that alone would fix the problem, and might screw up the backup. (Worst comes to worst, I can wipe & repartition the drive and restore from somewhat dated OS X and Winclone backups, but that's Plan B given the time and hassle. Not my main machine, so no worries about data loss...just a pain.) Thanks.
