I have a G-Raid RAID-0, but having a RAID-0 doubles the risk of data failure, so we're trying to format it as RAID-1 using FAT32 or any other filesystem that will support both MAC OS X & Windows 7. How could we do this?
MediaFour has recently updated their MacDrive code to include support for Apple RAID partitions on Windows. This was previously only available in an older release circa Win2k, with their former Cross-Stripe edition.
I've never used the G-RAID myself. By your first post, I took it to mean the enclosure didn't do hardware RAID 1. After having a quick read through the manual for the drive it appears the device is perpetually stuck in a hardware RAID 0.
It appears their G-RAID mini has a RAID 1 option, however.
Assuming you're using this for video I would avoid Fat32 and use either MacDrive or Paragon Software's HFS+ for Windows.
It looks like you won't need the Apple Software RAID support with MacDrive Pro, so could likely get away with the standard version.
Both MacDrive and Paragon have trials available of their software.
