Using bootcamp creates disk errors on Macintosh HDD

Hello,

Recently (in the last week) I have started playing the Witcher 3 on the Windows 7 partition of Bootcamp.

However, every time I try and switch back to Mac it automatically boots in Disk Recovery Mode since disk errors have appeared.

When I used Windows before this didn't happen.

Usually (it has happened 4/5 times already) the disk errors are:

Keys out of order
Invalid Volume File Count
Invalid volume directory count
Invalid volume free block count

So far, it has always managed to fix the errors, but I am worried.

I have tried erasing the windows partition and creating a new one but the problem seems to persist.

Does anyone know how to solve this?

I have updated all the bootcamp drivers to the latest ones and I am running Yosemite on the Mac partition.

The only other programs I have installed in Windows are: Chrome, AVG and MacDrive 8.

MacBook Pro (Retina, 15-inch, Late 2013), Mac OS X (10.7.5), Windows 7

likely the hd is dyeing

and you tie those symptoms to various things that happened around the time the hd began it's death throws

check the smart readings of the hd and be sure to backup data you find important

I checked the SMART readings and they were fine. Logging in directly on mac also didn’t cause any problems (I tried it a few times over the last week).

However, logging into windows did immediately cause the problems mentioned above. While the HD may be dying, it seems quite coincidental that it only, and consistently, happens after having used windows.

Does chkdsk get invoked regularly your Windows partition? If yes, your mechanical HDD may have a large number of bad blocks, which is likely to get worse.

You may want to consider http://www.smartmontools.org/ and run some diagnostics and capture data.

Chkdsk doesn't get involved and I checked bad blocks both from Windows and Mac.

I solved the issue by uninstalling MacDrive, so Windows couldn’t write on Mac drive anymore.

I am not sure what was causing it but since uninstalling it I haven’t had any more problems.

You should report this back to MacDrive Tech Support. My experience with third-party NTFS/HFS+ products is not very pleasant. I use NTFS-3g (2010) if necessary. It is much more stable than any current third-party software for such needs.
