Tokyo-based computer hardware maker Logitec [JP] (not to be confused with Logitech) today announced an external 1TB HDD [JP], which will go on sale in Japan at the end of next month.

The LHD-ED1000U2L comes with a power saving feature that makes the HDD drive rotation stop if the user doesn’t access the device for one minute. Windows fans can adjust the time by themselves (the HDD also works with Mac OS 9.0.4-9.2.2 and Mac OS X 10.1～10.5.1).

Logitec’s “green” HDD is likely to remain Nippon only. The device will cost $250.
