Problems with USB-Devices

[chlehmann]

Hi
I have a Problem with my USB-Devices (mostly harddisks).
The Problem is the following: when i connect a harddisk to my pc, it
makes a connection, an this acoustic signal comes. After a random
duration, suddenly the drive is dissconnected, and i can listen to the
acoustic disconnect-signal again. Afther that, it restores the
connection automaticly and so on...

i've tried it with a couple of harddisks, a usb-hub, and with a fresh
windows-install... nothing helped

do you have an idea?

greez& thanks

chris

Hard drives make some human range audio (noise) when spinning up, and may
also during access. Both occur when connecting a USB enclosure containing a
hard drive when a compatible OS is installed.

What are you basing your observation of a connection and disconnection on?

Sounds like you are talking about the USB connect/disconnect tone.
Perhaps your USB port is turning off to save power.(set that in Device
Manager) or you have a flaky USB port on the computer(try a different one)
