Just dd /dev/zero to the complete device. That purges everything you |
22 |
need: partition tables, boot sectors, contents: |
23 |
|
24 |
# dd if=/dev/zero of=/dev/sdX |
25 |
|
26 |
where sdX is the disk to "kill". Be sure not to purge just on partition |
27 |
by saying sdX1 or so but the complete disk (without number). Then, |
28 |
before running any partitioning software, reboot, so the partition |
29 |
cache of the kernel becomes cleared, or run part-probe if it is |
30 |
installed. |
31 |

dd should also be available in solaris but I guess the whole-disk |
33 |
devices are named differently. |
34 |
|
35 |
A faster alternative may be ddrescue. You could also give dd bigger |
36 |
block sizes: |
37 |
|
38 |
# dd ... bs=1M |
