Making Problems with NEC controllers

I bought an old laptop hard drive to a daily backup of my little C to make this housing partition. For the processing and special screws was said yes enough so I will not go into it here. What is, however, to complain about, the problems of these hard disk associated with NEC controllers. The hard drive enclosure seems to have a chip Asmedia which does not see itself with the NEC chip on my motherboard, the hard disk is ejected by the minute and read again! There seems to be a common problem (Google) between the two chips. At the USB2.0 port the whole thing runs like clockwork the way.
This is a return would not be worth the drive initially remains on USB2.0 port

Since I could not herrausfinden which the manufacturer has messed up his chips / driver I give totzdem 5 stars because of the good P / L ratio.
