如何格式化硬碟

建義你先看

以下例子是格式化 Primary IDE Master 硬碟

觀看 後，我們知道 Primary IDE Master 硬碟名稱是c0d0。

請先行 Login 成為 root user

# drvconfig ( configure the /devices directory )
# disks ( creates /dev entries for hard disks attached to the system )
# format
Searching for disks...done

AVAILABLE DISK SELECTIONS:
0. c0d0
/pci@0,0/pci-ide@7,1/ide@0/cmdk@0,0
1. c1t6d0
/pci@0,0/pci9004,8178@f/sd@6,0
Specify disk (enter its number): 0 ( 因為 Primary IDE Master 硬碟名稱是c0d0，所以選擇 0 )

AVAILABLE DRIVE TYPES:
0. other
Specify disk type (enter its number):0
( 正常應該是 0. DEFAULT 1. other，通常應該選擇DEFAULT，但是Solaris不明白我的硬碟是什麼，所以只有other可供選擇。)

如果是選擇DEFAULT，藍色字的內容可以不理。

我的IDE HardDisk架構如下:-
( 可以從BIOS Auto Detect查出來，通常都有LBA,LARGE,AUTO三種選擇，建議你使用Auto，因為不能大過16Heads和不能大過63Sectoes )
Cylinders = 25232
Heads = 16
Sectors = 63

Enter number of data cylinders:25232
Enter number of alternate cylinders[2]:
Enter number of physical cylinders[25234]:
Enter number of heads: 16
Enter number of data sectors/track: 63
Enter rpm of drive[3600]:
Enter format time[default]:
Enter cylinder skew[default]:
Enter track skew[default]:
Enter tracks per zone[default]:
Enter alternate tracks[default]:
Enter alternate sectors[default]:
Enter cache control[default]:
Enter prefetch threshold[default]:
Enter minimum prefetch[default]:
Enter maximum prefetch[default]:
Enter disk type name (remember quotes): cyl 25232 alt 2 hd 16 sec 63

現在打算把 /dev/rdsk/c0d0s0 mount 在 /mnt/newhd
# cd /mnt
# mkdir newhd

在 /etc/vfstab Auto mount 的設定

device to mount = /dev/dsk/c0d0s0
device to fsck = /dev/rdsk/c0d0s0
mount point = /mnt/newhd
FS type = ufs
fsck pass = 1
mount at boot = yes
mount options = -

# pico vfstab or vi vfstab
加入 /dev/dsk/c0d0s0/dev/rdsk/c0d0s0/mnt/newhdufs1yes-

# mount /mnt/newhd

完成 !
