Dead Hard Drive and My Process

So, I have been pretty sure for a while that the main Hard Drive in my desktop was going out.  It’s probably the oldest drive I own and occasionally it got feisty during reboots.  For a variety of reasons, I kept putting off replacing it.

… and putting it off…. and putting it off…

Then I went down to my office one day, the wife and kids were heading out for the weekend, I had grand plans to waste away my weekend on Overwatch and Battlefield 1.  Those plans came to an abrupt halt because I was greeted with a GRUB error.  My first assumption was that, as has happened before, Windows 10 did an update and screwed things up again.  A good while back I encountered  similar problem and after some troubleshooting I found that my Linux partition had been wiped out.  I reinstalled Ubuntu there and everything booted just fine.  Windows 10 had just done and update and after some searching online there were sporadic reports of similar issues.  After some troubleshooting trying to use a Windows disk to do a Master Boot Record fix and then trying to reinstall Ubuntu again, it became apparent that instead, the drive had failed.

This complicates things a bit.  I pulled out my SpinRite disc and threw it in the drive, hoping it would find and correct the error.  It instead threw out an error partway through the scan.  It’s an older disc, I’m honestly not sure if it’s compatible with the newer set up.  Instead I tried a copy of Norton Ghost to clone the drive to a spare 1TB drive I had in the cabinet.  It looked promising as well, though it also listed that it would take nearly 50 hours to finish.

I guess that meant no Battlefield but Overwatch runs fine on the laptop so a weekend of Overwatch and Netflix it would be.

Unfortunately, the clone crapped out as well after about an hour.

The final solution was to simply reinstall Windows 10, on a new drive.  I never use Ubuntu on the desktop so I opted not to bother reinstalling it.  I downloaded the official Windows 10 recover ISO and ran through the install.  During the install I skipped over entering the CD Key, Windows 10 is supposed to activate itself based on account credentials and hardware on the same machine, time to test that concept out.  The install finishes up and Windows 10 loads up just fine.  It’s even activated as promised in all of the Windows 10 feature lists.

The next task involves getting things back up and running order.

In recent years I’ve pushed a lot of my data off onto either my NAS or into Cloud accessible storage.  This makes this whole task much much easier.  I keep very little irrecoverable data on any one machine these days.  There are a few folders that I will need to recover from the old drive, but nothing super important, and I should be able to simply hook the drive up using a USB drive bay and do normal recovery operations to get to my data.

More interesting through, I ended up saving a ton of time and bandwidth with the games I had on the machine.  At one point I had nearly all of my 1000 Steam Games downloaded and installed, all of my GOG galaxy games and all of my Origin games installed.  These games are spread across several drives of varying size in this machine.  Once I reinstalled Steam, I set up Steam to use each of these drives and it simply detected all of the downloaded games, automatically.  The same happened with GOG Galaxy.  I didn’t see a way to make Origin to reattach to it’s old data so I just dumped that folder and redownloaded things as needed.

Honestly, ultimately this whole debacle has been a bit of a godsend.  I now have a fresh clean Windows 10 install, not one from my Windows 7 upgraded to Windows 10.  I also have a slightly nicer and faster drive as the main drive, which helps performance a bit.  It also gave me an excuse to purge out a lot of cruft I wasn’t really using.  I’ve shifted a lot of my computer use to my laptop, the desktop is primarily used for gaming, so it doesn’t really need anything else installed that doesn’t serve that purpose.

Cleaning up My Password Security

encryption-imageIt seems like there is an increasing amount of hacks and leaks lately.  These also seem to be larger and higher profile targets more and more.  Recently I’ve been seeing stories about Last.fm and Dropbox accounts apparently being compromised as well as a vulnerability in vBulleten, a popular Message Board hosting tool.  For the most part, a lot of these hacks are going to be harmless, for now.  Any website that actually matters is probably (they better be) using salted passwords, making a password dump mostly useless.  Though in Last.fm’s case, apparently 96% of the passwords were decrypted because their encryption algorithm was shoddy.  Still, it seemed like a good time to check over my Password Security.

Beware, those music scrobbles you see might actually be the music taste of some Russian or Chinese hacker!  Seriously though, I don’t really see the point with hacking Last.fm, I’m not entirely sure they even have any sort of financial data.  I imagine the email list is sort of useful for spam accounts.  I suppose there is also the issue of people using the same passwords everywhere.

The good side of these hacks, the lists get put on-line, on hacker sites or TOR sites, and there are several places that take these lists of leaked accounts, dump them in a database and allow you to search to see if your account shows up in a list and for which site, if available.  With all of these recent lists I went through and checked my primary email addresses and found about 20 entries between the two of them that had been compromised.  Most of those were vBulleten Boards that I had signed up for 10 years ago, never posted to, and had forgotten even existed.

I mentioned the problem of using the same password repeatedly.  I’ve got several “layers” I use for how much complexity I put into my passwords.  Financial sites, large buying sites (eBay, Amazon, etc), all get unique passwords.  I just remember those.  The next level, things like Facebook and Twitter, also get unique passwords, but I have some basic algorithms I use to generate them, mentally, so I can remember those as well while keeping them unique.  Sites like the ones that were compromised, tiny one off bulletin boards with little risk to me if they get hacked, I admit, I use the same few passwords on a lot of those.  Especially older ones from ten years ago, before I got serious about my online security.

Ironically, these sites are now possibly my most secure passwords.  Because I used Lastpass to generate the passwords.  Lastpass is a plug in for pretty much every browser.  It remembers your passwords, and syncs them across your Lastpass account.  I’ve used it for years to store and sync passwords, but I never really bothered with the generated passwords feature.  The best practice at the moment, for passwords, are long strings of random characters, lastpass can create these, and then remember them, so you don’t have to.  I don’t know what my new password is for the PPCGeeks message board, but I don’t need to, because when I visit, Lastpass will enter it and log me in.  It’s long and complex.  I mostly avoided this feature before because it pretty much meant I would never be able to log in via mobile since I would have to manually type the password in.  Lastpass now has a mobile solution, but I also just sort of accepted that, I’m never going to visit many of these sites on mobile anyway.

The even better solution, when available, is to use 2 Factor Authorization.  Something you know, a password, something you have, an Authenticator.  Every mobile platform has an authenticator App.  If you happen to be one of the 1% using Windows Phone like me, the Microsoft Authenticator works just like the Google Authenticator when setting it up.  When I want to log into say, Dropbox, I enter my username and password, like normal, and then I am prompted to enter the generated code from my Authenticator.  It doesn’t matter if someone else has my password, because they don’t have the Authenticator, which is randomly generated and can’t be duplicated.  I use this for any site that has it, which is almost all of the “big ones”, Microsoft, Google, Dropbox, etc.  I actually get frustrated when it’s not available, like when my Rockstar Games account got stolen 6 months ago or with Playstation Network, which has had like 3 or 4 hacks now.

Self Driving Cars

Robot Car

Every so often, I’ve seen the “ethical dilemma” of Self Driving cars come up for debate.  Specifically, the scenario goes something like this:

A self driving car is approaching a crowd of children, it can veer off a cliff and kill the occupants, saving the children, what choice does it make?  Who is responsible for the deaths?”

Its a dilemma to be sure, but it’s also completely absurd and effectively a non issue, which is an angle no one seems to really look at or realize.  This specific scenario is completely absurd because, why are a bunch of children blocking a road on the side of a cliff to begin with?  It can be toned down to be a bit more realistic of course, what if it’s a blind corner, maybe the children are just on a street and it’s just a crowd of people and not children.  The children are just there to appeal to your emotional “Think of the children!!” need anyway.  Maybe the alternative is to smash into a building at 60 mph after turning this blind corner into the crowd of people.

No wait, why was the car screwing around any corner where people may be at 60mph?  That’s highway speeds, there’s a reason we have different speed limits after all, open view open areas like highways are faster because we can see farther down the road and we have more room to swerve into other lanes or the shoulder and not into buildings or random crowds of people.

Exceeding the speed limit like that is a human problem, not a robot problem.

So, maybe the car is obeying the speed limit, maybe the brakes have suddenly, inexplicably, failed, and the car simply can’t stop…

No wait, that doesn’t work either.  Brakes generally don’t just “fail”.  A robot car will be loaded with sensors, it will know the instant the brakes display even a little bit of an issue and probably drive off to have itself serviced.  Or at the very least it will alert the driver of the problem and when it reaches a critical stage, simply refuse to start or operate until fixed.  Should have taken it into the shop, that on demand last minute fix service call will probably cost you three times as much while you are late to work.

Looks like ignoring warning signs of trouble is also a human problem, not a robot problem.

So what if there simply isn’t time to react properly because it’s a “blind corner”?  Maybe some idiot is hiding behind a mailbox or tree waiting to jump out in front of your self driving car.  Except this is still more of a human problem than a robot problem.

All of these self driving robot cars, are all going to talk to each other.  You car will know about every crowd of people in a twenty mile radius because all of the other cars will be talking to it and saying things like “Yo dawg, main street’s closed, there’s a parade of nuns and children there,” and the car will simply plan a different route.

They will even tell each other about that suicidal fool hiding behind the tree.

Maybe your car is alone, in the dark in a deserted area.  First, it’s a robot, it doesn’t care about the darkness, if there isn’t some infrared scanner attached telling it there is someone hiding somewhere, it’s going to still see the obstruction.  It will be able to know “How fast could a dog or a person jump out from behind that thing, how wide should I swing around it, how slow should I pass by it.”

It knows, because this is all it does.

Speaking of dogs, or possums, or deers, this also becomes a non issue.  The car will be able to see everything around it, in the dark, because it can “see” better than any human.  It also constantly sees everything in a 360 degree view.  The self driving robot car will never get distracted rubber necking at an accident, it will never be distracted by that “hot chick” walking along the side of the street, it will never road range because some other robot car cut it off (which won’t happen anyway).

It just drives.

And it will do it exceptionally well.

And even if our crazy scenario comes true, even if a self driving car has a freak accident and kills a buss full fo children every year or really every month, it will still kill fewer people than humans kill while driving.

So feel free to waste time debating which deserves to die, the driver or the pack of people, or debate who is responsible, you may as well ask who will be responsible for cleaning up all the poop cars make when they replace the horse and buggy.
