how to connect external hdd?

hello,

i have a toshiba hdd from my old notebook that doen't work anymore (lenovo, bought about 1.5 years ago) with some data i want to rescue. there's win7 installed on it.

i tried to connect the drive to my new notebook (hp with windows 8, the old hdd is in a box with SATA/USB 2.0) but it doesn't show in the list. i tried several things, all ports are working fine, drivers are updated etc. but nothing worked.

can anyone help?

thanks.

You could try this fix from the windows 7 forums, don't know if it will help.
