Put External Drive in Mac Pro, not recognized?

[matty1551]

I have a WD Mybook 3tb usb3 external drive that I use for backups and to store some media files. I've been thinking that I would get better read and write speeds if I took the drive out of its case and installed it directly in my mac pro.

Well I did this, however, it says the hard drive can not be read. Upon putting the drive back in its case and connecting via usb, it is recognized just fine.

What am I missing here? The drive is already formatted for Mac so I don't understand what the issue could be.

Probably just some "firmware" in the WD enclosure, between the USB socket
and the Hard drive itself.

May be that you would need to re-format the drive to use it internally.

When you installed the "bare" drive into the Mac Pro, did you open Disk Utility?

Does DU recognize "the presence" of the drive "on the internal bus" ??

Even if it doesn't mount on the desktop ??

It is on the internal bus. It's just not formatted for some reason. Upon further research I found some forum posts stating that WD Mybook's encrypt your data in some form.

After copying my external content to my internal and reformatting in Disk Utility, it is now functioning as expected.
