# hdparm -g /dev/sda

/dev/sda:
 geometry      = 19457/255/63, sectors = 312581808, start = 0

Poradi nekdo jak mam prepocitat bloky na sektory, abych to mohl zapsat zpet?

Dekuju moc

Počty cylinrů jednotlivých partition mně vychází:

[r@kvaslinux ~]# echo "(2 * 8193118 + 63) / (63 * 255)"|bc -l
1019.99993775287892934951
[r@kvaslinux ~]# echo "(208845 * 2) /(63 * 255)"|bc -l
26.00000000000000000000
[r@kvaslinux ~]# echo "(145018755 * 2) /(63 * 255)"|bc -l
18054.00000000000000000000
[r@kvaslinux ~]# echo "(2867602 * 2) /(63 * 255)"|bc -l
356.99993775287892934951

tj.

1. 1020 cyl
2. 26
3. 18054
4. 357

nejak to nesouhlasi s tou tabulkou v /proc/partitions, co?

[Franta Hanzlik]

Tě srando, to vypadá že to bylo rozdělované několika toolsama a každý si myslel o geometrii něco jiného. Ten výstup gpart-u vypadá celkem věrohodně... Zkusil bych zapsat "gpart -W" výstup do souboru, omrknout, a zapsat do MBR.

mam z toho podobny pocit :) Ale narval sem to tam co bylo v gpartu a linux i wokna najely
