Comment entered by Jay in r1234 seems reasonable.

Yeah, I meant to update this issue the other day but got sidetracked. I went to 
test this on my VMWare Fusion Windows 2003 system and discovered that 
disk_io_counters(perdisk=True) returns an empty dict for me. Obviously that's 
not correct as there are valid disks on my system, and winobj shows 
PhysicalDisk0 etc.

I'm not sure what's going on but it looks to me like the PhysicalDisk0 is 
returning an invalid handle and hits the break statement, short circuiting the 
rest of the iteration. Question I guess is why the invalid handle would be 
getting received and what if anything can we do about it.

Jay can you look into this on your 2003 box?
I can't reproduce the problem you're descripbing on Win XP/7.

I should have fixed this in r1569 .
Since there's apparently no way to figure out how many drives we should expect 
I set a maximum of 32 iterations, which is higher than the number of letters in 
the alphabet (A:\ -> Z:\, aka 26 possibilities).
kotsifi, Jay: if you guys have the possibility to confirm this is fixed (I 
don't as I couldn't reproduce the issue in the first place) please confirm, 
otherwise I'm going to assume this is fixed.
