I have an external hard drive with 3 partitions. Lately, seemingly at random, the partitions are becoming unmountable (usually one per day). Running Disk Utility always repairs the partition without issue. Its very annoying. Any suggestions?
I just noticed that when this happens if I simply unplug the external drive's USB cable and plug it back in, the partitions all mount properly. The only way to mount them without unplugging is to "repair" them.
