Had 250gb Hitachi Deskstar. Was using it as portable and dis not have
plate over circuitry (big mistake?).

Was working fine with my usb adapter and driver on both old and new
systems. Usb adapter and driver works fine on other drives still.

Suddenly the Hitachi will no longer respond to the loading usb driver
and is not recognized by 2 independent systems. No error message. No
noises or clicking from drive, sounds normal spinning up.

I guess I must have touched the circuitry and destroyed the controller?
Is that the reason?

They are called DeathStars for a reason.

Its more likely it just died. There's a reason there was a full class action suit over those drives.

I just had an issue I resolved for my own external hard drive. It turned
out that the problem was the power supply that plugs into the USB
enclosure. There was power flowing through one of the rails but not the
other, so the USB interface kept working and it would appear in my USB
connections list, but there wasn't enough juice to actually run the
drive behind the interface. Simply changed the power supply.

Just touching the circuitry rarely destroys the hardware. It
may destroy a bit of data though.
