It is at least true under normal circumstances... iirc though, the test harness uses PED_SECTOR_SIZE to force parted to ignore the size the disk reports and pretend it has a larger sector size. Is that what is going on here? If so then then problem is only with the test harness and I'm not entirely sure using that override that way is really supported. In other words, this kind of feels like a "don't do that" bug. On the other hand, I suppose it wouldn't *hurt* to fix it. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (MingW32) iQEcBAEBAgAGBQJU1RICAAoJENRVrw2cjl5RheIH/iEu4lhFO5S+gHILhOPjQ2yL nQKNoBUA8G1it6JZAH9Hk7+lXbWjk1Eh0tCQZ/4uQh0r4NbeYbQRbIt/6LpT6w2f //bE93IhC4abZoce8xz1ENI5tQAW+jc5im3mqfiq+mQ1jNSthDJVNUUjN91mV6dW fPxalrBCMjdMeEZ9Qcu75kpCVGxQwdYMSxFGIFZV5W6wZU5aXPkcFkzeUcjHjr6J qNNx7ANhR7tMYZopbSeb69S4B/yT9mNlAL7wijBRUlXUqJBlyfxFuKawX+JDGYd0 rbYraoVr00V7fSltWoYC15+R4JQCc5XJTrbS5YTNgzQhv/AU1pk5odBWuWEDOqk= =NRjF -----END PGP SIGNATURE-----
