Q: OSX and Bootcamp discussion
-
Aug 19, 2014 8:44 AMby Christopher Murphy,Since it looks like everyone's going to get CoreStorage volumes by default with Yosemite, even if they don't use FileVault 2 or a "fusion" drive, I'm going to guess that Apple's Bootcamp drivers for Windows will enable Windows to read CoreStorage volumes.
But this has always been read only support in the past. I wonder about 3rd party read/write HFS+ support, which will not work on a CoreStorage volume until that software is updated to support CoreStorage.

Before Bootcamp (via CSM-BIOS), this is what it looks like...

Sep 1, 2014 7:51 AMby Loner T,Some additional testing using ML 10.8.5 and CoreStorage. This is an example of reducing/creating new volumes when the original volume covers the entire set of two disks. (This is a 512GB SSD/1TB HDD Mac mini 2012).
Original CS volume…
