I dunno,but say what i also use a el cheapo HDD casing -"Supercomp 2.0 USB" casing for my 3.5" SATA Segate 750 HDD.Numerous times have happened when the Hdd drive has shut itself up after sometimes/aprrox 10-15 min of use or even when data r getting written on it with a similar message like "Delayed Write Fail"... "...dunno what to take out from that,but have always re-started the hdd after that to get it back working GOOD. Checked with Seagate hdd check agent/acronis disk director & Hd tune, Not to find any fault. Lucky mayb!!!
** 1thing,i dont put the HDD within the casing enclosure,but rather leave the hdd open just attached to the control board of the casing!
