My USB HDD wont work with USB 2.0 however it is USB 2.0 compatible.
I just bought a new usb 2.0 card that plugs into the PCI slot and my jumpdrive works fine but my HDD doesnt even load. When i plug it into the old 1.1 slot it works though.

The HDD itself is a 40GB Hitachi HTS424040M9AT00 and is put together by the company BlueEye

Can anybody help?

it could be a problem with the slot rather than the HDD itself...maybe the driver isnt installed?

usb 1.1 tends to be slow in transfer..maybe u should just replace the 1.1 with a 2.0? theyre pretty cheap.

did you even read his post Albert_Chu?

the speed most likely has something to do with your harddrive. although networking anything (including external harddrives) is going to be slower than if id was internal.

You said earlier that your drive is "USB 2.0 Compatible". That simply means that it will work with USB 2.0. It doesnt mean that it has a USB 2.0 interface. The truth is that any USB 1.1 device is USB 2.0 Compatible (because USB 2.0 is backwards compatible with USB 1.1)

I just discovered that about my drive enclosure. While the specs say "USB 2.0 Standard", and it is a revised version from the original USB 1.1 model, the interface speed is still listed as 12mbps, which is what I would expect from a USB 1.1 interface - USB 2.0 should be running at 480kbps.

See the specs here

It could just be a typo, but Im always wary of the phrase "USB 2.0 Compatible".
