Unable open destination drive for Writing?

[dumpav]

I am trying to upgrade my Humax DTR800 from 80G to 500G

I dl the PTV free iso for this process.

I hook up my device in this order

Primary master ide > original tivo drive

Second master ide > cd rom with boot up PTR disc

Second slave ide > seagate 500G

when i type

dmesg | grep hd

it list my
hda have 80G
hdc is the cd rom
hdd is the 500G

but

so i use this command:

mfsbackup -Tao - /dev/hda | mfsrestore -s 250 -r 4 -xzpi - /dev/hdd

and after it scan when it start writing it said

cannot open destination drive for writing.

any advice what i should do?

thanks!

Typically, that message indicates the drives are not mapped correctly to the letter in the command. In your example, it appears OK; are you sure of the drive-letter mapping? You don't have /dev/hdd mounted?

As the previous poster has indicated. Your command is fine if the drives are hooked like you indicate they are. Have you tried this more than once after turning off computer and letting it sit for a minute or so. You can do the process over and over without hurting anything since mfstools reformats every time it runs.
