I've used ext2/3 drivers in 32-bit windows and it worked fine... 64-bit windows is a crapshoot, there's so much stuff that doesn't support it. I use dm-crypt for backup DVDs (full disc, not container-on-unencrypted-disc), I once tried to mount one using freeotfe (i think?) in Windows, and at the time (years ago) it was unable to mount a CDROM like that and I never tried it again. I haven't tried a hard drive. For now I mount it in linux and access it from windows over the network. (VPN from windows to linux box + samba/cifs/whatever)
