I bought several of the Orico 128 and 256 MSATA drives while they were on sale. I tested them last weekend to see if I had any failures before return dates expire.
I was testing on a Windows machine and I'm no expert on disk formatting/initializing preparation, but perhaps someone can make something useful of this tidbit.
On Windows, none of these MSATA drives were initialized at all. Whatever the step is before partitioning, that wasn't done. So they weren't MBR nor GUID in Windows. I had to open disk manager and right click the left-most entry for the MSATA drives and choose "initialize" and then select MBR or GUID before I could get them to do anything, such as move on to partitioning.
I'm not sure how that relates to Mac usage, but perhaps someone else does. I'm used to drives arriving with basic formatting already done, which can be undone if one wishes. These had nothing.
I hope this can help JDW's situation.
