Ext. HD turns off intermittently.

Your problem is overheating, more so with 2 HD's in the same case,

Remedy: make sure you have a insulated heat abzorber between HD's and install a fan ( motherboard fans are perfect minor alteration needed)

Worked perfect for me for over 3 years, make sure your Hd's are secure they don't like rough handling.

Sheesh, I was saying that I have two SEPARATE HD's in separate cases. One is used a bit, but the other is barely used. Sometimes they will turn off after 5 or 10 seconds (Cmon, hardly enough time to heat up). Even after that, they will come right back on and run the whole night.

What I was saying that coincidently BOTH of them are acting up in the same manner, at different times, and when on different computers, too.

If your ext Hd is under your laptop with no heat resistant material between, plus the heat off the power transformer, plus in a confined space ( case ) and with no fan to cool it your HD will not work;

take it or leave it, I run three systems with 2 x 500's in each case and don't have any problems'

I run 4 ext HDs 500 gb, no fans in ext cases and never had a heat problem.
4 yrs of this. they run perfect.
started out as 250 gb and now are 500 gb.
so i believe your problem is not heat related. Bob

I see. my HD is away from any heat source, in an air conditioned room. When I first noticed this, it was outdoors in the morning, no sun, in the shade, windy day (wind will remove heat), and away fro any other heat source, and it was less than a minute before it blinked off.

Bobcox, thanks for realizing it may not be heat related.
