USB external drive not recognised

[zoohair]

Hi,
I have a USB Mass Storage device(external HDD enclosure) that is able to be detected by Win XP and Linux, with the drive volume also being detected and able to be accessed. However, OS X doesn't seem to detect the volume. It does however detect the USB-IDE bridge chip, which means the USB chip is enumerating correctly? I'm wondering why then doesn't it detect the volume? Disk Utility also doesn't see the drive.

You sure the drive is plugged in all the way? Also what is the drive formatted as?

well since its brand new and wasn't recognized by the mac i had to test it out with the pc which means it is currently as NTFS , and yes im sure, i even tried having it plugged in the DC power incase it wasn't getting enough juice but that did nothing

Any suggestions?

recognizing a usb drive

I have had the same problem. Tried everything in the book with no success.
I finally just switched to a firewire drive and it works great and totally dependable.

It's also possible OS X needs drivers to recognize the IDE/USB adapter.

In other words, it sees the adapter, but doesn't see the physical disk, because it doesn't know what the adapter is.

No idea what chip is on the adapter, so best way is to get a new enclosure.
