Powering a 3.5 IDE hard disk via USB ports?

[godwin.coelho]

Is there any way to power a standard 3.5 ide hard disk via usb ports?
are there ne adapters like this?

 

[Bob I]

they require 5volts AND 12volts so NO.

There are external hard drive enclosures that will do this. However, they
usually require a separate power supply for the unit.

I have a device (box) called a "drive kit "that purports to do just that.
You are supposed to be able to install any IDE deivce in the box and connect
via USB,,, that includes CD-Rom and DVD-Rom devices along with standard hard
drives. You can leave a device in the box permanantly or swap them out. It
has a standard 110v connection and includes a fan for cooling.

In other words, the answer is NO! You always need external power for a USB
external hard drive.

Hi Richard -

For 3.5" drives, probably so.

For 2.5" notebook drives (and probably 1.8" drives as well) this is not
always the case.

I have an external USB 2.0 enclosure that uses two USB ports for connection
with no external power required. One USB port is used for the data signals,
as well as up to 500ma power. The second connection provides up to an
additional 500ma power. If you check the specifications, most 2.5" drives
use less power than this, even spinning up.

i got an USB HD enclosure for 3.5 HDs. It's got its own power supply.
everything seems ok. it's recognized. It's when I'm copying files. I
can copy files bu it suddenly stops, disappears from My Computer. Light
is still on. external HD is still runnning. But windows can no longer
see it. I have to unplug/replug USB and unplug/replug power for
windows to see it again.

what's happening?
