I need to copy partition table for sda, I have 3 primary partitions and 1 extended partition on sda. I understand that fdisk cant copy extended partition table and I need to use sfdisk.
Correct me if I am wrong -
- For primary partitions
dd if=sda-mbr.bin of=/dev/sdX bs=1 count=64 skip=446 seek=446
- For extended partition
sfdisk -d /dev/sda2 > backup-sdX.sf
Where it will store the files after backing them up. I tried SUSE 11.2 DVD, it has back up partition table utility under repairs-advanced options but it suggests saving partition table to floppy. Why it doesnt offer to save it on a removable medium or to CD.
Best,
David
You can use sfdisk to dump this info in a readable format which can be used as input to sfdisk again.
-d Dump the partitions of a device in a format useful as input to
sfdisk. For example,
% sfdisk -d /dev/hda > hda.out
% sfdisk /dev/hda < hda.out
will correct the bad last extended partition that the OS/2 fdisk
creates.
This option is particularly useful for duplicating the partition table of the working disk of a RAID1 pair to a replacement.
Thanks, ken_yap; will try that soon.
Secondly, I need to clone the hard disk, what tools i should use.

Exact copy, dd. Otherwise, perhaps ghost for linux.
