OK, replying to myself after having played around a bit with both Unix under Billware and vice versa:
1) - Somehow the HDs turned into a "GPT Protective Partition", which XP cannot read. Googling a bit reveals that XP cannot read these (although a utility for destroying and reformatting is available). XP not touching it is A Good Thing I think. Sorry for letting this slip into a Billware support question, but: ----> Is it safe to have a guest OS raw-accessing these discs, without worrying that the data being destroyed by an XP host? 2) - Using XP under OpenSolaris (build 134, most recent VirtualBox) is still not appealing -- even having done a fresh install. It is unbearably slow, I can't even play a media file on an external USB soundcard (using pass-through). So ... either WinXP host, or another box. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
