I almost prepped myself up this Friday evening for a solo Debian reinstall party to solve an extremely slow reading/writing on internal hdd/sdd problem until I accidentally realized the problem disappeared once I had removed my external disk from the docking station. Went from 2mb/s to 2gb/s r. and 800mb/s w. > I spent several hours fixing a problem and I learned next to nothing in the process. This trick is unlikely to be useful again. By the time I encounter something similar, it is likely I will have forgotten about the solution. So much this.
