Hello I have a MX-M363N sharp copier. It will be off lease soon. Does anyone know if the data stored in the hard drive can be erase? I called leasing company and they said that no data was stored in it. Document filing is disabled.  

Re: erase copier drive

Never mind I found it in the manual searching for the keyword hard drive. There is a automatic deletion settings section.

If it is IDE or SATA, and modern enough, you can
use the built-in Secure Erase function.

To use this, I recommend reading *all* the documentation.

Secure erase has some reliance on a "password". And the
password is there, I presume, to prevent malicious
erasure attempts. With a Sharpie, you can write the
password on the drive.


A more carefree solution is DBAN.

To use it, you need:

1) Computer, with just the optical drive connected.
2) Connect the victim hard drive.
3) Blank CD, with DBAN "OS" loaded on it.
4) Boot from CD.
5) DBAN can erase 100 hard drives in parallel, if
    all of them are connected to the machine at the same
    time. Don't do anything dopey, like connect your primary
    drive and backup drive to the machine, then do the
    erasing. In the DBAN forums, there were always a few
    lovable losers who would erase their backup drive and
    lose all their data. Funny funny stuff.

That's why you use the safety precaution, of *only*
connecting the hard drive to be erased. All other
valuable drives, at the very least disconnect their
data cables. We wouldn't want to see you begging in
the DBAN forums, for some means to restore the data :-)


All erasure products, can have issues with HPA (host
protected area). You can check for an HPA from Linux.
On my current computer, my BIOS locks HPA options on
the SATA ports, but (fortunately) leaves the third-party
IDE chip open. And by using an IDE to SATA adapter,
I was able to both set and remove an HPA from a drive.
Normally, there would not be any information of interest
inside an HPA, unless you were a spy, and hid stuff in
there. Some disk setups, there is an OS of sorts hiding
in there.


I'd give it a half-hearted erasure with DBAN, a
single-pass erase, and call it a day.

I have other ways to do that, like

    dd if=/dev/zero of=\?\Device\Harddisk1\Partition0

which erases all of the disk appearing second down
from the top in Disk Management. It doesn't matter
what kind of partitions are on the disk, or even
whether the MBR is invalid (a raw partition). That
command should still do it.

(Windows command line...)

but like anything disk related, one typing mistake
could spell disaster. Having a machine with only
the victim drive connected (the DBAN CD way), is
a plus, as there is no danger.


Windows provides "diskpart", and the "clean all" command
may also do something similar to what "dd" would do. Like
many other methods (even "dd"), it would ignore an HPA
and not erase it. Just the visible part of the disk gets
erased, sector by sector.

Have fun,

I would not be surprised if securely erasing the HDD in a device such as a
copier actually breaks the device or, perhaps a better way to put it might be
"renders it impossible to use its main function - copying" because of whatever
firmware / internal utilities that might be stored there. If you can return a
broken off-lease device with no penalties, then sure, the best way to ensure
that noone can see what you've copied is secure erase.

OTOH, I imagine if you erase the image storage part  of the HDD using the
internal "erase" function of the copier, you are not actually erasing images,
you're just updating the filesystem that the machine uses. Anyone who's
sufficiently interested in what you've copied may still get to the images.

So, the choice appears to be between returning a broken copier and assuming that
the images are not completely and securely erased.

From Google:
"80-GB HDD; 38-GB for Document Filing System and Electronic Sorting"

It looks like you want to take care to ensure you only erase the 38-GB  
assigned to the Document Filing System and Electronic Sorting. I would not  
be surprised if the leasing company has simplified matters. If you return  
the copier to the lease company and if an employee is curious, they may have  
access to material you have copied or faxes received.

In a government setting the HDD would be removed and shredded.

From the above Sharp link you can access a number of manuals:

Yes, I think you should investigate how to erase your stored data.
