Since a few days, my udoo ocassionally loses connection to the connected SATA drive. /dev/sda simply disappears without a trace. Sometimes it reconnects, sometimes I have to restart multiple times for it to work again. The UDOO is not moved nor should the cables be moved. Might that be an overheating issue?
Could be. We have a couple of UDOO connected with SATA and with both of them we use this case: https://www.indiegogo.com/projects/ucas ... metal-case Never had a overheating issue.
