It would appear (though I have no proof) that WD is now using WebDAV instead of CIFS/SMB when making connections between a Win7 box (and maybe other systems) and PRIVATE shares on the MBL.
This is leading to some rather annoying behavior; there’s lots of indirect mentions of this in other threads, but I’ll summarize what I’ve seen as consequences.
1- It’s INCREDIBLY slow.
a) Copying a large (10GB+) file, I only get 6 megabytes per second write. Copying that same file to the PUBLIC share (which uses SMB) I get 50+ Megabytes per second.
b) DELETING a single folder that has 10,000 files in it takes about 10 minutes to “Discover,” and then individually delete each file. Doing this on the PUBLIC folder takes about 10 seconds; the whole folder is deleted at once.
2- Poor utilization of drive space… The WD creates MANY (2x) DAV files / folders, and those files and folders are consuming 10% of the space on my drive. I copied my 44GB iTunes library over; the WD created 10,000+ DAV files that take about 5 Gbytes of space… it’s wasted space.
3- Intermittent Errors:
When DELETING that iTunes folder, I got about 30 errors: “The file name you specified is not valid or too long. Specify a different file name.” What? *I* am not specifying a file name; Windows is.
When COPYING files to the MBL, I get errors: “The file is too large for the file system.”
