如何清除GPT標簽

１）看到ＧＰＴ很不爽

# fdisk -l /dev/sdc

WARNING: GPT (GUID Partition Table) detected on '/dev/sdc'! The util fdisk doesn't support GPT. Use GNU Parted.

Disk /dev/sdc: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdc doesn't contain a valid partition table

2）先把前兩個ｓｅｃｔｏｒｓ洗掉

# dd if=/dev/zero of=/dev/sdc bs=512 count=2; sync
2+0 records in
2+0 records out
1024 bytes (1.0 kB) copied, 0.00061 seconds, 1.7 MB/s

３）ＧＰＴ標簽還在

# fdisk -l /dev/sdc

WARNING: GPT (GUID Partition Table) detected on '/dev/sdc'! The util fdisk doesn't support GPT. Use GNU Parted.

Disk /dev/sdc: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdc doesn't contain a valid partition table

４）再把后兩個sectors也洗掉（500107862016 / 512 - 2 = 976773166）

# dd if=/dev/zero of=/dev/sdc bs=512 seek=976773166 count=2; sync
2+0 records in
2+0 records out
1024 bytes (1.0 kB) copied, 0.000616 seconds, 1.7 MB/s

5）完成。

# fdisk -l /dev/sdc

Disk /dev/sdc: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdc doesn't contain a valid partition table
