Urgent: Copy hda to hdb with dd?

Run fsck.ext2 on your drive. Make sure it is read only or not mounted of
course because fsck will give you an error. Your drive keeps inodes of how
big it is and what is where etc. The very same thing can happen with dos so
you would run scandisk and it would report that the drive is reporting the
wrong amount of free space. Fsck should do same.

Subject: Re: Urgent: Copy hda to hdb with dd?

Thanks Hans.  I've been following this since I'm doing something
similar, but having different problems.  I used DriveWorks to
partition the new drive and Ghostpe to copy (but partimage looks good
from freshmeat).  Unfortunately, my Mandrake 8.1 kernel doesn't try
to use the expanded "/" area.  "df" says:
Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/hda2              2008140   1846164     59964  97% /
but the partition is about 8Gig.  The whole idea of a new drive!

sfdisk gave me the following part. table info:
Disk /dev/hda: 4865 cylinders, 255 heads, 63 sectors/track
Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0

   Device Boot Start     End   #cyls   #blocks   Id  System
/dev/hda1          0+   1083    1084-  8707198+  1c  Hidden Win95 FAT32
(LBA)
        end: (c,h,s) expected (1023,254,63) found (1022,254,63)
/dev/hda2   *   1084    2103    1020   8193150   83  Linux
        start: (c,h,s) expected (1023,254,63) found (1022,0,1)
        end: (c,h,s) expected (1023,254,63) found (1022,254,63)

        start: (c,h,s) expected (1023,254,63) found (1022,0,1)
        end: (c,h,s) expected (1023,254,63) found (1022,254,63)
/dev/hda4       2486    4270    1785  14338012+  1c  Hidden Win95 FAT32

        end: (c,h,s) expected (1023,254,63) found (1022,254,63)

Several red flags, I'd say! I fixed the partition type for hda3 (now
82). Mandrake didn't seem to mind.

However, although the cylinder numbers appear OK for each partition,
the expected and found start and end values are totally off (they
repeat for all the parttitions!). Will sfdisk (or some other
routine) clean these up? By imaging one part. at a time, deleting &
restoring? Or do I need buy another new drive and construct it
cleanly?

Altho Alan is making multiple copies, I use a 2nd drive as a backup
that is only powered up to copy to.

Handy site to use. Thanks.
