No, 7-8 remained as-is. ad7p1 was created using: #gpart add -t freebsd-ufs -s 10G -b 63 ad7 So it begins at sector #63, but physical 4096-block begins at logical sector 64.

WD Green disks suck. Is it a problem of WD Green or it is common to all 4096-sector models? -- С уважением, Илья Бакулин (ON Labs)
