So, yesterday I got myself a new HDD, for extra storage space, at home. I installed it with no problems, then booted Vista (for the more familiar interface) and attempted to format it using FAT32.
Apparently though, 150Gb is way too much for a FAT32 partition and Vista only allowed me to format using NTFS.
I would respect that it didn't allow me to perform an invalid formatting, that would have ruined my new hard-drive, except it isn't so: I booted under Linux and was able to format the partitions with no problems whatsoever.
It turns out that windows is simply lying to you, so that you'd be forced to use a proprietary partition format (leading to platform lock-in) :(
At least, that's the only conclusion I could come up with.
In this case however, all they managed was make me give another vote to Linux.
