controllers.’ He began working on this in late July, noting that at
this time drivers for the formentioned hard drives ‘mostly work,’
and he has continued to clean up the infrastructure based on
suggestions from libATA author Jeff Garzik. Lukasz went on to note,
‘once the infrastructure is accepted, anyone with a
hotswap-unsupported controller and some time on their hands will
