MP 1,1-5,1 Converting an external hard drive into an internal drive for Mac Pro 5,1

[mightyjabba]

I've got several USB drives that I would like to use as internal drives on my new Mac Pro 5,1. I thought this would be as simple as removing the drive from the enclosure (shucking it) and then putting it into the Mac Pro's drive sled. However, it tells me that it can't read the drive and asks if I want to reformat. If possible, I'd like to avoid this, and I'd also like to know what the issue is because I thought this approach should work. Any input?

Most USB enclosures from big name HDD manufactures, Seagate and WD love this, use a specific way to partition the drives and won't work after you remove it from the enclosure and connect directly to the SATA ports of Mac Pro.

If a drive then ask your for a reformat, you have to copy the data via the enclosure and then reformat after installed inside the Mac Pro.

Thanks, reformatting isn't huge deal but it will require me to do some shuffling of files around to different drives.
