can't mount drives

[mhodges]

I've recently started getting errors of SD not being able to mount drives to clone from. After repairing permissions on the boot drive I've gotten a few to mount but I've yet to get others to "mount" at all with SD during the copy process. I've tried rebooting and disk repair and all the drives in question check out. Everything was working fine until recently but I can't seem to find anything that has changed. Some of my drives to be cloned are 90% full. Could this keep them from being mounted during a smart update? What should I look for during trouble shooting?

No, shouldn't be a problem. So -- the don't "mount" meaning you have them ejected and they don't automount during schedules?
