Many people are still trying to find a 2.5" drive that will work correctly with a TE4 Bolt, and not fail within a year or so. I still think the best solution is to go with a good quality 3.5 PMR/CMR drive in an external enclosure. The drive in the enclosure ideally should be connected directly to the Sata port on the Bolt MB. And get it's power from the enclosure. Mine has been working well for quite awhile now. I did not even have to cut the Bolt case, I used a couple cardboard shims where the cable comes out of the Bolt. And used two cables that can connect/disconnect so can separate the Bolt from the enclosure easily. Here are some pics if anyone interested. No Esata being used, the cable coming out of the Bolt is connected to the Sata port on the Bolt MB, the cable coming out of the enclosure is connected directly to the Sata connection on the drive. Added bonus, since no drive in the Bolt it does run a bit cooler. Not as much as I expected though, most of the heat must come from the MB/CPU, not the drive.
