It is. Just make sure you add the right PIDs. I got a K2, and read some of the 0s as Os. I figured if it wasn't right, I wouldn't get a PID. Well, I did, but it wasn't until Calibre started importing as AZW, that I realized I had the wrong PID. It is useful to try the PID with mobidedrm6, first.

Thanks! I needed the upgrade.

I've found that there's even a problem with 0.07 and some Mobipocket books, resulting in extra or wrong text every so often. Hopefully there'll be a 0.08 along shortly to fix those. (Specifically, Mobipocket v5 files that don't have trailing data entries, event though the header is 0xE8 long.)

[edit] And I've received notification (I get emailed when there are new comments) that there's is a new version of the code linked from the Dark Reverser's weblog comments.

This one seems to be a combined stand-alone script /and/ calibre plug-in.

Awesome, thanks for the tips.

v0.09 is out now (7 Jan 2010)...

None of the new versions of mobidedrm work on my drm files. Just an old version of .02 does. Any help with compiling the calibre plugin with the old .02 version? Thanks.

The calibre plugin is not a different program. It is a different startup procedure inside the same program:

if not __name__ == "__main__":
	from calibre.customize import FileTypePlugin

	class MobiDeDRM(FileTypePlugin):

		name                = 'MobiDeDRM' # Name of the plugin
		description         = 'Removes DRM from secure Mobi files'
		supported_platforms = ['linux', 'osx', 'windows'] # Platforms this plugin will run on
		author              = 'The Dark Reverser' # The author of this plugin
		version             = (0, 0, 7)   # The version number of this plugin
		file_types          = set(['prc','mobi','awz']) # The file types that this plugin will be applied to
		on_import           = True # Run this plugin during the import

	
		def run(self, path_to_ebook):
			of = self.temporary_file('.mobi')
			PID = self.site_customization
			data_file = file(path_to_ebook, 'rb').read()
			ar = PID.split(',')
			for i in ar:
				try:
					file(of.name, 'wb').write(DrmStripper(data_file, i).getResult())
				except DrmException:
					# Hm, we should display an error dialog here.
					# Dunno how though.
					# Ignore the dirty hack behind the curtain.
#					strexcept = 'echo exception: %s > /dev/tty' % e
#					subprocess.call(strexcept,shell=True)
					print i + ": not PID for book"
				else:
					return of.name

		def customization_help(self, gui=False):
			return 'Enter PID (separate multiple PIDs with comma)'

if __name__ == "__main__":
	print "MobiDeDrm v0.07. Copyright (c) 2008 The Dark Reverser"
	if len(sys.argv)<4:
		print "Removes protection from Mobipocket books"
		print "Usage:"
		print "  mobidedrm infile.mobi outfile.mobi PID"
	else:  
		infile = sys.argv[1]
		outfile = sys.argv[2]
		pid = sys.argv[3]
		data_file = file(infile, 'rb').read()
		try:
			file(outfile, 'wb').write(DrmStripper(data_file, pid).getResult())
		except DrmException, e:
			print "Error: %s" %

Question is: how much work would it be to patch the startup code into the older versions.

Well, hardly any work. But it's the wrong question. t

The right question is why is this person having problems with later MobiDeDRM?

There are /lots/ of files that 0.02 doesn't handle correctly. I thought that with 0.09 we'd finally tied down just when Mobipocket files have trailing data flags or not. I haven't come across any on which it fails.

v0.09 seems to work OK, but I've only used it a few times. I suppose I could go back and re0try it on all those archived DRM files?

I wouldn't bother until we find out whether or not this is operator error.

Where do you have mobidedrm script? What OS? You might need to type ./mobidedrm02.py because the current folder isn't automatically in the path.

It's just over two years since the Dark Reverser first posted his MobideDRM script, and just over 21 months since I started buying DRMed Mobipocket books because of it.

Eeekk.. The Dark Reverser's work has meant I've spent over $1600 on ebooks in the last 21 months!

Oh... working it out, that's just under $18 a week. And so far this year, I have been reading books at a cost rate of about $15/week. So I suppose I haven't been too wildly extravagant.

So - three cheers for the Dark Reverser!

If you want to do it through ADE you have to install the Sony Library software in order for ADE to recognize the reader and allow you to copy books to it from within ADE.

Oh and yes, the reader has to be registered to the same Adobe ID that you have your Mac registered to or the ebooks won't work on the device. Of course, this won't keep the device from being recognized.
