I may try to boot my old kernel and see if it works as it should there. I'm pretty sure I connected the new enclosure a couple times tho to the old kernel and it worked. I'm just not 100% sure. I'm just wondering if something I enabled might affect how it works somehow. I mostly followed the Gentoo dm-crypt wiki except that I enabled a few extra encryption logarithms. Thing is, given the 770T has a newer kernel than my main rig, hard to compare. I got my backups moved around so I won't need to hook it back up for a week or so. If I get the chance to reboot tho, I can always test it then. Wol, I used USB a few times on some old enclosures I had. I bricked a few hard drives with those things. I was always getting data errors and eventually, the drives would die. Oddly, one of the enclosures worked fine. I stopped using them when I bought the ones I use now. Dale :-) :-)
