Hi there, I connected an ExFAT formatted external HDD that I routinely use to store applications installers (both Windows and Mac, and bigger than 4GB, hence choosing ExFAT since NTFS is read-only) to a Windows 7 virtual machine on my Mac. This drive has seen OS X commonly reporting an error and refusing to mount it, unless I manually checked it in Disk Utility. This checking failed, of course, but it seems to be a known issue of ExFAT on the Mac. Now, for some reason, Windows sees it as unformatted, as for Mac OS X, it is unreadable. Given the short time it was connected to Windows and that the disk was mostly idle, I am pretty sure a glitch happened in the virtual machine and the data is still there, and only "something" in the partition header has failed. Where should I go to ask this question that seems to be Windows-specific? Is there a way, say, with a Mac software, to switch the drive back to its original state?
