The Mac HD drive doesn't appear in Windows, even though it did some time ago (maybe a year ago?). Running 10.10.1
(was upgraded from Mavericks). Really wish it were there so I could read files off it! Thanks for the help.
OS X Yosemite (10.10.1)
Yosemite can convert your disk to a CoreStorage volume (check the output of the terminal command - diskutil cs list ). Also, please see windows 8 does not recognise Macintosh HD, No drive Letter.
Apple does not provide CS volume readability (as it did for a JHFS+ file system) as of Yosemite 10.10.1.

Thanks for the reply. It says "No CoreStorage logical volume groups found"
That means yosemite didn't convert it from HFS right?
Do you use FileVault2? Are Bootcamp drivers installed? Do you have more than one version of OSX installed on your Mac?
Can you post a text version of the output of diskutil list (remove any personal information as you see fit)?
I don't think I use FileVault; in security and privacy under preference it says it's turned off. I don't know what FileVault2 is though.
Bootcamp drivers are installed and function normally for everything else in windows. Only 1 version of OSX on this Mac.
Here's diskutil:
/dev/disk0
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *750.2 GB disk0
1: EFI EFI 209.7 MB disk0s1
2: Apple_HFS Macintosh HD 449.0 GB disk0s2
3: Apple_Boot Recovery HD 650.0 MB disk0s3
4: Microsoft Basic Data BOOTCAMP 300.3 GB disk0s4
/dev/disk1
#: TYPE NAME SIZE IDENTIFIER
0: Apple_partition_scheme *21.5 GB disk1
1: Apple_partition_map 32.3 KB disk1s1
2: Apple_HFS Wildlife 21.5 GB disk1s2
FV2 is described here - OS X: About FileVault 2 - Apple Support.
Can you check under Disk Management in Windows?
Here's a screen cap of disk management in windows- it seems to acknowledge the space exists where Mac HD should be but isn't reading it.
Your MBR is incorrect. There should be two entries before BC/Windows. a 200MB EFI, and then a 449GB HFS, but your display shows a single protective MBR. Was the BC MBR manipulated by any utilities like GPT Fdisk?
The diskutil list and this layout do not match as you can obviously see, so you cannot see your HFS+ volume.
Can you post the output of
sudo gpt -vv -r show /dev/disk0
sudo fdisk /dev/disk0
I used Alcohol 120% recently to mount a drive, maybe that had something to do with it? Is there some way to fix this?
I don't really think it was working before I used Alcohol 120, and I don't think that messed with the partition tables.

Yes.

Partition manipulation should be done very carefully. Data loss discovered too late is very painful to recover from. 😉

Rebuild MBR to match GPT information thus resetting the Hybrid MBR. Use defaults for other questions (like partition codes). The boot flags only impact Windows. The Bootability of OSX is EFI-based.
Test and verify.
Worked!!! so amazing much genie wow.
My Mac HD partition will not appear in Windows 8.1, how do I get read access in windows?
