[OT] unhosing .rev and .livecode files

Richmond Mathewson-2
Aa all forensic software for digging in blanked hard drives seems to
find the most obvious
files, and NOT .rev and .livecode files I wonder if anyone has any
bright suggestions how one might
go about looking for them.

Look for the file header text at the beginning of every stack:

like
REVO7000
REVO5500

you may need to do research on the headers for the vintage stack formats.

There should also be a file termination character(s)

That sounds great, but I wonder exactly how I should look for the file
headers.

Hi Richmond,

Glad to hear that you've been able to rescue most of your files. The
Data Rescue programme I use is imaginatively called 'Data Rescue' by
Prosoft. I don't think it would help in your case as I don't think the
Mac version can recover non-Mac HDs. The reason I mention it is that
it has a feature called 'FileIQ', so you drag a .livecode file onto
FileIQ, it then learns the structure of an LC file, then you can Start
Data Rescue to search all similar such files on a HD. I'm sure it
wouldn't be the only Disk Rescue programme that supported such a
feature.

Good luck.

PS. Every single LC stack I create, no matter how large, small,
trivial or world changing, sits in a suitably named folder within a
generic folder 'my stacks' which lives on my Google Drive. I have
plenty of back-up options (as covered by Richard) as I just can't
afford to loose a HD, but for reasons I can't explain, for LC Stacks I
feel it necessary to have quadruple redundancy back-up. Some one on
this List mentioned using Dropbox or Google Drive as a working
location for their stacks, and since following that advise I've been
most thankful. No fuss, no thought, works a treat.

Just one additional level of warning - if you keep Dropbox or Google Drive online, malware can get there too. Usually the baddies just trash your directory, but if they encrypt everything you have accessible online, Dropbox and Google Drive won’t help you. Offline backup is essential, offsite is even better.

“Diskwarrior" is a good tool to use in addition to “Data Rescue”.
If you have to go as far as using “Disk Rescue” you have had
some major problem and may not have been doing your
backups routinely enough.

If you already have a safe-deposit box at a bank, you may want to
consider using that as your offsite backup storage place.  The idea
being that you have a couple of backup drives, one at home and
one in the bank.  Every week or day depending on how much you think
you can afford to lose, visit the bank and swap the drives.  Then you
aren’t trusting the internet with important backups.

Yes it’s old school, but it works!

Just my 2 cents for the day. ;-)

I use Time Machine for hourly backups, mirror my LC stacks folder on Dropbox (so every change is also saved in the cloud), then in addition I have a peripheral hard drive at work where I back up my work stacks every time I close down for the day. I once lost over 2 weeks of notes due to a disk crash, and that taught me that it’s not a matter of *if* a disk will fail, it’s a matter of *when*. Never again.

Re: [OT] unhosing .rev and .livecode files

Richmond Mathewson-2
Thanks, one-and-all, for the kind and informative messages about backing
up and so forth.

I have retrieved as much as I am likely to from my zonked Linux box, and
am now putting the
thing back together.

HOWEVER, before that:

1. Retrieved from one of my hard drives was a "rather intriguing" set of
extremely foul, hard-core
porn images which I most definitely did not download onto that drive.

Looking through a load of old receipts I discovered that I had bought
that hard-drive second-hand.

2. So, at the cost of losing 2 more days time, I am doing a seven-fold
deletion thing offered by
Macintosh's Disk Tools as have no very great desire to find that set of
images popping up again.

3. I also noticed all sorts of advert images which, I, similarly did not
download onto my hard drives;
so can only conclude that whatever webpages one visits, those webpages
dump their images onto your
hard drive in some sort of cache that is not purged properly subsequently.

4. I have invested in a 4 TB external hard-drive as well as a further
three 2 TB external hard-drives
so that I cans et up some sort of rotating system as Richard Gaskin
suggested.

5. I am using a 1 TB partiion on one of the 2 TB hard drives as a
Time-Machine disk for my newly acquired
2006 Intel Mac.

As I was completely unable to retrieve the log files from my hosed
system I have no way of knowing
what zonked my Linux system. What I do know is as follows:

A. The computer (DELL Optiplex 754) works perfectly alright, having had
it up and running doing
forensic stuff on a variety of Live Disks (Xubuntu 16.04, GParted, Hiren's).

B. The night before it "died" I was accessing an external disk that was
freezing up the machine, and
I wonder if the "culprit" was something on that disk.

Richmond.

Re: [OT] unhosing .rev and .livecode files

your drive was probably at some time used as a Torrent server source.
Yes definitely delete all porn, don't even bother seeing if it contains
illegal porn. Chances of child porn are very likely in a Torrent folder,
and one has no idea where's it's from or been.

In the US the son of a friend of mine was thrown in jail for 5 years by the
feds and jailed as a sexual predator for what was on his hard drive. The
federal prosecutor got the defendant's independent examination thrown out
of court which would have proven his innocence and made it hard for him to
defend himself. He's still there.

Whilst your overall comment is extremely valid, that everyone should
have some sort of offline back-up, the sentiment about Google Drive I
think is false and probably driven by articles such as this:

http://blog.teklinks.com/ask-the-engineer-why-dropbox-wont-help-if-youre-the-victim-of-cryptowall

The statement that versioning is just a few hours or a couple of days
at most is just wrong; certainly in the case of Google Drive, and is
just a perfect example of how so many of us do not really understand
the programs and services we use and the options available to us:

http://fieldguide.gizmodo.com/keep-older-versions-of-your-documents-on-google-drive-f-1671188573

If Richmond had Google Drive synced to his stacks (which I appreciate
he doesn't), then even at the default setting, if there was some
crypto attack on his computer I would NOT discount the effort of going
to your Google Drive and looking at the old versions kept - there is a
little clock icon against any file that has multiple versions.

Not only that, Google Drive has a menubar icon which becomes active
only when it's syncing, ie I've just saved a stack. It spends most of
it's time as a static Icon, so if it starts up at a random time and
doesn't stop it's a clear indication to pull the ethernet, USB,
Thunderbolt and FireWire cables and shut the computer down immediately
- especially if I were to click on the menubar Google Drive Icon and
the files it listed as being synced are ones that I haven't worked on
for ages. Had to pull cables a couple of times over the years,
although not for uncommanded Google Drive activity but for network
traffic that didn't seem right.

Cloud based sync is not THE answer, it's just one of many cheap and
easy options that should be ADDED to our stash of computer
prophylactics. Only if your network bandwidth is thin and/or expensive
would you not avail yourself of the side benefits of free Google
Drive/Dropbox.
