No, 7-8 remained as-is. ad7p1 was created using: #gpart add -t freebsd-ufs -s 10G -b 63 ad7=20 So it begins at sector #63, but physical 4096-block begins at logical secto= r 64. That's why I shifted gnop by 1 sector. > No, performance blows. :-( But this drive was bought primarily as backup solution. That is a good choi= ce according to your blog entry :-) > Yes. WD Green disks suck. Is it a problem of WD Green or it is common to all 4096-sector models? --=20 =D0=A1 =D1=83=D0=B2=D0=B0=D0=B6=D0=B5=D0=BD=D0=B8=D0=B5=D0=BC, =D0=98=D0=BB=D1=8C=D1=8F =D0=91=D0=B0=D0=BA=D1=83=D0=BB=D0=B8=D0=BD (ON Lab= s)
