Good day, I believe this is the right forum for this post. I have searched the forums here and have not found a solution; so I shall post my problem as follows. The title say it all. I have installed 9.1 on my computer in a dual boot configuration with windows 7. Each OS has its separate drive, and GRUB2 determines which OS I boot into. There are 4 drives in this system, two are standard HD's (one for freebsd FreeBSD 9.1), the Windows drive is a SSD and I have a hybrid drive for all my Windows applications. When I boot into 9.1 x64 it recognizes and can mount all my drives except for the hybrid drive. When I reboot into Windows, the MBR, FAT and a lot of the data is gone from the hybrid. I have no problems with the hybrid drive in this configuration using OpenSUSE or Fedora. But I would much prefer to return to FreeBSD. I should add two additional items. 1 - I initially noticed this occurring in PC-BSD 9.1 x64. As it is based on FreeBSD, I installed FreeBSD 9.1 x64 to see it it solved my problem. No joy, the data on the hybrid drive was still lost. 2 - I only noticed this after the FreeBSD and PC-BSD were installed and updated packages applied. So I can't honestly say if it was an updated package that caused the problem or not. Has anyone else experienced this problem, and/or know of a fix as I cant afford to reinstall / restore everything to my hybrid drive every time I reboot into Winsdows.
