GPT って、カーネルがサポートしてないと使えない?
良くわかってないので、勉強必要。

ude:~# parted -s /dev/sdb print Warning: /dev/sdb contains GPT signatures, indicating that it has a GPT table. However, it does not have a valid fake msdos partition table, as it should. Perhaps it was corrupted -- possibly by a program that doesn't understand GPT partition tables. Or perhaps you deleted the GPT table, and are now using an msdos partition table. Is this a GPT partition table?
