Hey folks -- I found ways to stablize my EP950. As pointed out in this and other forums, this product is badly designed for heat removal. They simply put no slots or holes to encourage air movement out of the box, and with an internal 2TB HD, it cannot BREATE. As a result, I found that even using USB PC to 950 transfers, I would get unrecoverable HD errors. Modern Hard Drives are very stable and can easily tolerate running warm --- that's what they're spec'd for. But alas, it appears the 950 circuitry could be stressed, and start to contribute to drive data corruption. Of course, there are other matters of how to format, and what works best. For me, on a 2TB Hitachi, I let the 950 do the format first, so as to create the two additional partitions --- then place the drive in a PC and format just the Primary partion (NTFS), and verify all is well.
But the key problem is cooling. So I willingly got into the box and did my own changes, to help air flow. This involves some drilling around, and all this made my EP950 "behave". First, I removed the top cover (there's a small grommet on one side), and then lifted up and removed the plastic drive tray assembly (four small screws, lift up toward the right, and then unhook the two drive SATA cables). On the hinge side of that tray, I drilled out a bunch of holes --- its all simple plastic and easy to work on. Next on the bottom of the tray are a series of slots, which would ordinarily be right above the 1186 heat sink. With simple tools, I snapped off those plastic slots, so much more air could get through. For the top cover, I drilled out a series of holes, using a series of larger drill bits, on the hinge side of the cover. The metal is thin and easily worked, and I made sure to clean up the holes (and cover) of all stray filings and sharp edges. What all this will accomplish is let the box have some air intake (besides just that dumb ext SATA cover) to keep the PCB cooler.
One more thing I did was replace that inadequate fan on the right side of the housing. I checked my pile of junk, and came up with an acceptable 12VDC micro fan, just slightly larger than the original. I had to snap off some of the plastic ribbing near the fan area, and also drill a few holes to accommodate the fans mounting holes. It is all easily worked plastic. When the fan was installed, and the wires properly spliced in, I made sure that the drive tray basket would fit without interference. No problem. (If you do this, dont forget to plug in the SATA cables!)
So now the tray was in, the HDD drive verified it fit OK, and the SATA connector all OK, the top cover was reinstalled. When you turn it on, there is substantially more air flow coming out of the box rear, which contributes to keeping all the components happy. Before that, playing a 1 - 2 hour video would result in freezes, or lockups or mysterious Micca reboots. Now everything works OK, the fan is barely noticeable, and I have a stable 2TB box crammed full of videos and pictures.
This worked for me!
