I have to use sd** when using cryptsetup to decrypt the drive. I haven't found a way around that that is easier yet. My command was something like cryptsetup open /dev/sdk1 <name> and then it asks for the password. After that, I use UUID and a entry in fstab to mount. If there is a easier way, I'm open to it. I have three external drives and as long as I only power them up one at a time, they all used sdk. Now they use sdd and I keep trying to type in sdk, from habit. :/ My next project, find a good external drive enclosure like the three I got now. They no longer available tho. I like them because they have a fan, a eSATA port and a nifty display to let me know things are working. Really a good price for the features. I don't like USB connected drives.

I just disabled it for sdd, enabled for the new sdk and restarted the service. It was happy then but getting a email from SMART always makes my heart beat a few extra beats and sometimes causes me to swallow big too. It's rarely good news. Maybe the next reboot will sort things out. Then I get to switch everything back to the old way again. :/ Dale :-) :-)
