Piping dd through gzip to image Win2k Partition

After reading Awesomemachines thread about dd again I am trying to learn how to gzip a image file of my Win 2k partition. The thread shows the command:

Quote:

dd if=/dev/sdb2 ibs=4096 | gzip > partition.image.gz conv=noerror

Obviously, my partition arrangement is different and this is the command I tried while running Puppy:

Quote:

dd /dev/sda5 ibs=4096 | gzip /mnt/sdd7/Win2k.image.gz conv=noerror
and
dd /dev/sda5 ibs=4096 | gzip /dev/sdd7/Win2k.image.gz conv=noerror

this fails saying both /dev/sdd7.. and /mnt/sdd7 are not valid directories or files, so what have I done incorrectly here?

Further info: the sda5 partition is NTFS, and the sdd7 partition is Fat32.

My Win2k partition I have already successfully cloned with dd by using the command:

Quote:

dd if=/dev/sda5 of=/dev/sdb5 bs=4096 conv=notrunc,noerror

This worked without a flaw and I have successfully booted and ran this clone.

NTFS or FAT partition shouldn't matter, if you just can read them. The native ntfs driver is able to read just fine, so shouldn't be a problem (and the error is elsewhere).

Did you notice you're missing one ">" from your commands?

You can use partimage to achieve a similar result. The nice thing about partimage is that it doesn't back up the free space on the partition. It can handle Microsoft file systems.

You may find partimage is in the software repository of your distribution. Then you could use your distribution's package manager to install it.

Partimage will not work on a mounted partition.
