Hi, Ive recently upgraded to a macbook pro from a powerbook and Im having some problems with some USB devices, namely a USB 2 card reader and 3.5 inch external HDD.
When I connect them to the macbook growl informs me that a connection has been made, e.g. USB mass storage device, but nothing else happens and if I try to start disk utility (to check if the HDD is mounted) it just gives me the spinning beachball.

Some background info - both of these devices used to (and still do) work on my powerbook.
The HDD Im having problems with is windows formatted (Fat32 partition and NTFS partition). It works on my powerbook and works under windows xp (Bootcamp) on the macbook - OSX is the only thing that doesnt recognise it.
I have another HDD, same type of HDD, same enclosure except formatted on the mac and that works ok (so it cant be the enclosure, especially as windows picks it up too).
The card reader is just a standard generic card reader, nothing special and again works on the powerbook but wont mount on OS X.

Im a bit confused as to what I can do to resolve this - googling just mostly resulted in recommendations to change the enclosure but as the same enclosure works on the powerbook and under XP on the macbook I dont think thats it.

Any ideas please anyone?

Thanks in advance for the help.

Regards,

Andrew

It might be the way you formatted the Windows disk? Have you tried reformatting the problematic hard disk?

Also, are both your devices showing up in System Profiler?

The disk isn't recognized by the Mac OS, which I've seen happen before. The fastest way to fix this problem is to attach the drive to a windows machine and reformat it. Then plug it into the macbook.

Start with the drive with the least information on it (flash drive) and see if that makes it readable for your mac. If so, let me know and I'll try and find the process again that will fix this without reformatting.
