No detection of Harddsik

[jochemvanengers]

Hey everybody,
I've got a problem:
My External Harddisk is not showing up in finder, and not even in the disk utility.
USB ports are tested with several other devices and work fine.
External Harddisk is working on another PC AND a Macbook early 2008, same OSX and intel Based.
My harddisk is NTFS formatted..
Harddisk is an external powered toshiba 3,5 " 320 GB of 1.5-2 years old. I cant find the exact modelnumber anymore...
Does anybody have an idea how I can get this to work?

thank you very much

Hello, have you tried unplugging the external drive and trying again?

 

[jochemvanengers]

Yup I tried everything...
On another forum people are having the same problems, a lot with firewire ports too... But no solution yet...
ANY IDEAS? This cant be true on a new $ 2000+ laptop

Have you tried plugging something else in the same firewire port to see if it works?

Oops, sorry, that threw me off when you mentioned "a lot with firewire ports too". I take it that when you "unplugged" the external drive you not only disconnected the usb cable from the Mac, you also turned off the external drive and unplugged it from it's power source as well. One more thing, have you repaired permissions on the Mac?

Yup I tried all kinds of unplugging and plugging in, power on and off, etc etc..
I just ran the repair permission tool in disk utility (thats what you mean right?, wasnt familiar with that before) unfortunately no changes...
