For me, it's a big hassle to open the player, and pull out the disk and archive it that way. So I just dup the recorded programs to DVD+RW to archive them on USB hard disk. My experiments were only for possible contribution here, I actually don't have a need for it
I'm still hoping some Linux user can try that dd command since many people who are upgrading from a 80 or 160GB drive could use it to copy their files to the new 500GB (or whatever size) new drive in one raw copy op... they won't have to copy each title to DVD, copy back to HDD, etc.

Here's the latest info on this subject in the help file on file systems
, etc.:HDD Copy
A Philips 3455 user copied the entire contents of one HDD to another using the Linux dd command ("copy and convert a file"), and the new HDD operated normally, as described here.
He mentions FAT32 in the link above, but later here
he says the HDD that worked showed NO formatting using gparted Live CD. The "no-formatting" sounds right since I believe new HDDs we buy don't have a specific formatting cuz they need to be able to be formatted for all kinds of uses and operating systems.
The Linux dd command is a "raw" process that doesn't involve addressing and extracting each individual file one at a time. It's does a "global" copy from one HDD to another. (File extraction for title recovery is discussed in the next subject below.)
Since the 3455 was built in 2006 and our 357x and Mag series started in 2007, it's quite likely that our HDDs can also be copied to other HDDs with the Linux dd command.
Funai mfg'd all these units but since they only had complete "control" over the Mags, so we need to check each brand.Here's a short tutorial
on how to copy an entire HDD with the Linux dd command.Here's another tutorial
that describes how to use Linux to copy a smaller HDD to a larger one, like 160GB to 500GB as we like to do, and retain ALL the space of the larger one. SInce that specific command might be hard to find, here's the statement from the tutorial:
"If you duplicate a smaller partition to a larger one, using dd, the larger one will now be formatted the same as the smaller one. And there will be no space left on the drive. The way around this is to use rsync."
