Who gets your digital pictures when your gone if nobody can find them? Back up your data.

Who knew FPL would be responsible for my thinking this through.

I take a lot of pictures.  I mean a LOT of pictures.  Anyone who dabbles in Photography does.

The last time I looked, between video I shot, intermediate edits, final edits, pictures, and so forth of things that made it through my hands, there are gigs worth of them.

Just a ludicrous amount.

I like looking at my pictures.   Some of you do out there too.  This blog is photography heavy.

My dog, my family, trees, birds, my engine bay of the Jeep.  Just things I like, just things that caught my eye.

Others may say that they’re boring.  After all, how exciting can it be when my dog even yawns at me.

I know many of you out there are exactly like me.

We have our family pictures.  Birthdays, Weddings, Thanksgiving pictures.

If you’re old.  Well ok, over a Certain Age, if you’re being kind, you even have them on paper.

You know, actual Photographs.

Believe it or not, they will last longer.

Why do I say that?  Think of it this way, there have been house fires where the “Family Album” or the wedding album of Aunt Grace and Uncle Jeremiah back in 1910 in front of their flivver featured prominently on the fireplace, survived.

A Flivver I have been told is a Ford Model T where as a Jalopy is an old car from that era.  Jalopy is still used if my arteries to my brain have not hardened and I am not halucinating due to lack of blood flow.

Oh look!  A Shiny Object!

Ahem.

So what about that wonderful digital thing, the digital camera.

Great things aren’t they?  You can take them anywhere because they’re smaller, a little more sturdy, and even these days fit on the back and front of most cell phones.

Give me a Digital SLR any day, they’re much more flexible, and you can get removable lenses.

No, I mean it if you have a spare…

Never mind.  Some day…. Hmmmm….

Anyway.  You have your beautiful DSLR that took the award winning photograph that went viral.  It’s really a weed but looks like a giant flower.  It could be the dimple in your two year old’s cheeks.  Even could be your dog playing.

All those thousands of pictures.

Remember that fire I was talking about?  It doesn’t have to be that drastic.

I had a friend.  Had.  He passed away.

His pictures won’t be making it back to the family.

They were on a computer because he was as gadget mad as I am.

Half of his pictures were undoubtedly on his phone.  Those pictures that were left on his phone are lost forever.  By now, his iCloud account has been purged along with whatever photographic treasures that he had set aside.

Family may want those, are you sure that picture you took might not better be used as a memory of you once you’re gone?  You’ll need to make sure you put it where they can get to it.

The remainder were splattered between a number of laptops that I maintained for him remotely.

He came up here once and I dropped his pics onto a CD-ROM.  Remember those?

They won’t survive a fire but having one here means that a few of his memories will escape onto facebook for whatever good that may bring.

In my case, I found out that I had a problem.

My power here is shoddy.  Sitting in the living room chair, lights dim, power may surge and hum, relays snap on and off and back on again.

I get up from the chair and turn off the breaker on the air conditioner…

 

Yes, it is October, yes I am in Florida, yes I will be air conditioning my house to 24C/76F in January, it’s part of the deal.

… and wonder what I lost.

This all comes out of a data recovery project.  How I preserve my pictures is to have them on an “external hard drive”.  Since I have an android phone, I can copy them to my server or my laptop with ease.  Specifically that is why I don’t have an iPhone, whether or not it is safer on their iCloud or whatever i’s have been left for access and not poked out with a pointed stick.

Just look to the //router/share/pictures directory and have at them.

Why was it a problem?  Those pops and snaps.  Any time your computer or your hard drive is subject to power irregularities, your data could get ruined.

So why am I suggesting keeping them on a fragile hard drive here at home?

For redundancy of course.

Sure you could get an account at one of dozens of online storage sites, but there’s a certain something about keeping the data close at hand.

Yes, even for my pictures of my dog.

I cleaned out the corrupt files, lost much less than I expected, decided that I really did not need that third copy of a linux operating system I stopped using years ago, and gave “the rug” a good vacuuming in order to get rid of the chaff on the hard drive.

So consider once you’re gone, your family won’t have those little pictures.  I’m beginning to think that history will be at a loss as a result of what made it so much easier to share memories.

Even if the Fotomat is long since turned into a couple extra parking places after the whole Film Photography thing went almost completely away.

I THINK the drug stores still do film processing… maybe not!

 

Securely Erasing Your Old Hard Drive Easily with Linux or a Mac

I have been thinking of the easiest way to completely and securely erase a hard drive lately.  I was given two old laptops and was asked by a dear family member to help get some personal effects off of an old laptop.

To keep this short, I was able to do that using an external hard drive case and my own machine.

Since I use Linux, I am immune to windows viruses, I can simply copy the desired data to my computer.  I now have a directory of 1.1 GB of pictures, writings and other information on my desktop which I will burn to a DVD and say “Here you go, enjoy”.

Mac people and other BSD people can rejoice in that as well.

She’ll need to scan that for viruses before she looks at it in detail since she’s on windows.

Ok, that’s all done right, just toss the drive in the nearest secure shredder or sneak it into the trash or….

Not so fast.

You see, data can be forever.

A CD typically lasts 10 years.

A CD that “you” wrote may not last that long, say 5 years.

A DVD will last longer, I haven’t had one that I wrote fail yet, and some are well more than 10 years.

I still don’t trust that removable and optical stuff.

But, if I can get the computer I am looking at now to recognize the drive, the data will still be there.  Useful or not.

Even those old 500 MB drives from the first days of the IDE era can be read if I have a way to convince my laptop to read it.  How?

Get an external hard drive case.   You need to know what kind of hard drive you have in your hands.

IDE External Cases are still available.

Serial ATA or SATA cases are available in USB 3.0 and 2.0 if you want cheap.

I paid under $5 for mine when they were on sale.

Put the drive in question in the case.

Plug the drive case into the computer.

Assuming that your computer can see the drive and the data on it, now what.  You’ve got your data off and you want to securely erase the drive.

Here’s where Linux comes in to play, although a Mac will work as well.

Don’t have a Mac or Linux computer?  The easy fix is to download a copy of Ubuntu and burn that to a DVD or to a memory stick and boot from that.   That is all done via a program called unetbootin and it is available for any modern operating system that I can reasonably think of.   Follow the instructions and you end up with a bootable USB stick.  Boot from that stick.  Plug the external drive in.

Now you’re looking at Linux.

(If you’re a Mac guy, you can to follow this on your Mac.)

Commands from this point forward will be in BOLD
Start Terminal.

Get root with “su” or “sudo su” and give it the system’s password.

Verify the address of the external drive.  “dmesg” will give the device name at the end of the display.  You can also find it in gparted (if installed).  The address will be similar to /dev/sdb.

Verify it again.  “Measure twice and cut once”.

In terminal enter the following command – I am assuming that the operating system thinks that the external drive is on “/dev/sdb”.  You need to know which partition and this will tell you where it is:

fdisk -l /dev/sdb

(Man, I hate Helvetica – That is a lower case -l )

On the Windows drive I have in question, it gave me two partitions – sdb1 and sdb2.  Windows being what it is, will almost always use sdb1 as the boot partition, and it will almost always be the largest one and the one in question with your data.

Since I have cleared out all the data that I would be worried about in an earlier step, I do not have to worry about deleting any partitions.  But I do have to create a space to work with.

Within terminal, mkdir work will make an empty directory to play with.

To access the data on the external drive: mount /dev/sdb1 work

To verify you have connected to the drive, cd work 

To list any data files you left in that directory, ls  will show you.

To create a big file to overwrite all that empty space enter the following command.

    dd if=/dev/urandom of=junkfile.txt

That dd Command will write random garbage out to the file called junkfile.txt until it runs out of space. Out of Space is a bit misleading because certain disk formats have maximum file sizes, so just run it again with a different name on the “of” portion of the command – like “junkfile1.txt” until you are satisfied.

That’s about it.   Your empty space on the drive has been filled with garbage.  You can delete that junkfile.txt and use the drive as a floppy if you like.  Since you previously deleted things that you wanted to be securely deleted, this happened with it was overwritten with random data.

The theory goes that with the “new” and “large” disks we have inside of our computers over the last few years, simply writing garbage out would be sufficient.
The Geek version was that the old drives had enough space between tracks that the data would sometimes, but not always, be mirrored and repeated in the empty spaces.  Some of the information could be “recovered” by reading that space.

You don’t have the technology to do that.  Any “normal” person finding your drive would not either.

New drives over the last few years are so densely packed that that space between the tracks is too small to store extra copies of the data.

If you are super worried (paranoid) about your data, give the drive to a destructive person, and some hand tools, and let them disassemble it for the magnets.  Or run over it with a truck.   Or both.

But this is as far as I go with my own personal data.
