Thumb Drive Management

PermaLink

It seems like everyone has a USB thumb drive/memory stick these days. I’ve observed two things. 1) when I ask people what they do with their drives, the usual answer amounts to “not much”. 2) when I service someone else’s PC and use my thumb drive, a lot of folks are quite interested in how I have mine organized. Thus the reason for this article.

I have several considerations. Among them

I listed those roughly in order of importance. I have several chronic medical problems including diabetes so having my medical info readily at hand even though I might be unconscious is very important.

This brings up a very important decision. How much info to make semi-publicly available? My complete medical history should be easily available to any doctor who needs it but it should not be available to anyone else, including nosy authorities.

The way I’ve addressed the problem is to place an open file on my thumb drive that contains my current drug profile and allergies plus my doc’s contact info. My entire medical history is in another file, this one encrypted and hidden. The people I list in the public file as emergency contacts have the password to access the encrypted file. I’ll provide details of how I set this up as we go along.

The Thumb Drive

If I’m unconscious, the thumb drive won’t do me much good if the emergency responders and ER docs don’t know about it. Many ERs now have computers available and know to look at thumb drives if they can find them. Other ERs have computers but the idea of emergency data being on a thumb drive hasn’t yet dawned on them. I need to get the attention of both types. Here’s what I’ve done.Thumb Drive 01

This is a Verbatim 4 gig drive, 2 for $20 at Sam’s Club. (Amazing!) I chose it mainly because it is bright reddish orange and because the keyring hasp is metal. On one side I’ve placed my name and home phone number. This is primarily to facilitate its return if I manage to lose it. I would have put my cell number but there is no cell service where I live.

Thumb Drive 02

Here is the flip-side. Here I note that “Emergency info Inside”. Hopefully that’ll spur someone in the ER to plug the drive in and see what happens. I carry this drive on a carabiner clipped to a belt loop so it’s always visible.

Thumb drive file layout

Here is a screen dump of the file layout in the root of my thumb drive. Click the image for a larger version. Let’s go down the list.

Files

V-Safe100

This app came with the thumb drive. I don’t know how cryptologically secure this program is but it seems good enough for the kind of stuff that I’ll be using it for.

When first run, it formats the thumb drive and allocates a designated amount of space for the encrypted volume that is separate from any windows file system. The encrypted file system is invisible to windows until it is unlocked

After formatting, when the program is run, a Windows Explorer window opens, pointed to the “root directory” of the encrypted volume. The unencrypted part as described above “goes away”.

Screen dump 02

In this screen dump, I’ve just clicked on V-Safe100.exe. It’s asking for my password. When I give it the correct password, the following appears in the Windows Explorer screen

Screen dump 03

Same Explorer window but now only the encrypted volume is displayed or accessible. The files being displayed are

Portable Apps

As I mentioned above, this is a collection of major applications and utilities that have been packaged to run from a portable memory device, even a read-only one like a CD. In addition to a thumb drive, this suite can be installed on flash memory cards, mp3 players and other portable media devices that connect to a PC.

These are mostly GNU apps, OpenOffice being the notable exception. GNU apps tend to be difficult to deal with, having to chase through several SourceForge screens and even other sites to find the installation package. The root of this is their extreme bias against anything Microsoft (I share that bias) and binaries distributions, and a certain religious-like zealotry. The guys doing Portable Apps have cleanly and neatly addressed all those problems. The GNU apps, like all the rest are Plug’n’Play.

To get started, go here and download the standard package. Yep, 90mb worth. Worth it. The standard package contains the most popular applications. OpenOffice, a file zipper, etc. Other apps are available from SourceForge.

This page lists what applications have been “portablized”. Downloading from that list is a PITA so go here to do your actual downloading. If you have the FireFox Extension Download Them All then you can grab ’em all in one fell swoop

Screen dump 04

When StartPortableApps.exe is clicked on or launched via autorun.cnf, the little round grey icon is installed on the status bar, visible as the first icon at the bottom right. Clicking the icon brings up the screen that is shown in the screen dump above. The list of applications scrolls so not all the ones I have installed show here.

FLASH memory is fairly slow reading and REALLY slow writing so be prepared for leasurly application startups and file saves. C’mon, you’re not in that big a hurry!

Application Notes

Here is some info that will save you some hair pulling.

Firefox

It is not a straightforward process to bring over your Firefox environment, skins, bookmarks, extensions, etc. That’s mostly Mozilla’s fault. One would expect it to be fairly common to want to have the same browser environment on more than one computer. That should be an option within FF. It isn’t so we have to go to Plan B. This page shows you how to do it. Look under Copying Your Local Firefox Settings.

Firefox must be closed for this to work! If FireFox is open when you copy the files over, most will be over-written when FF is next closed.

Also note the next section, Installing Plugins. I highly recommend the last option, titled If the above fails, try the alternate (and more geeky) method. This should be the FIRST option.

The first time you fire off FireFox after moving your settings, Firefox will churn a LONG time. At least 30 minutes on my old machine. This is not a bug! Firefox has to do a lot of thinking and reorganizing to accommodate the big dump of config files it just found. Be patient.

Also note that certain performance enhancers such as page caching are disabled in the portable version. This is so that the FLASH memory, which has a finite write life, won’t be constantly thrashed. This makes FF a bit slower but it’s a decent tradeoff.

Media Players

The two media players currently included in the package, VLC Media Player and and MPlayer are both vastly superior to the bloated crap normally used like Windows Media Player, RealPlayer, etc. Both play .flv movie files. In fact, both have played everything that I’ve thrown at them including some corrupted video files that WMP just tosses its hands up at and goes Tango Uniform.

ClamWin

This is a virus scanner. At this point it doesn’t do live scanning (looking at what is coming in). It only does a hard drive scan. It does that well and in a fraction of the time needed by the major name bloatwares. And since it doesn’t do live scanning, it doesn’t slow down the machine.

If you’re careful with your browsing and don’t use microsh*t virus transport software software like IE then ClamWin is probably all you need. They update the virus database several times a day.

Password Safe and KeePass

Both of these apps are secure password safes. I’ve used PWS for years and am comfortable with it. I simply copied the application and the encrypted database to my thumb drive. No other installation is needed. Unfortunately it hasn’t been “portablized” yet.

I’ve been carefully looking at and researching KeePass. I like the user interface and the added functionality. As soon as I’m convinced that it is as cryptographically secure as PWS then I’ll probably convert. So far everything has come up roses. It is open source and so has received a LOT of critical attention from crypto experts. It uses AES and Twofish encryption algorithms, considered to be the two strongest available.

What I’m watching now is the general nature of bug reports. I’m interested in whether there were any major programming gaffs which might indicate other structural weaknesses. So far I’ve seen nothing. Fortunately KeePass can import the PWS database so the transition should be fairly painless.

Summary

That’s about it. I love this setup and have kept the thumb drive plugged in whenever I was using this machine. Recently I uninstalled OpenOffice and several other apps and installed PortableApps directly to my computer. I did so for several reasons.

Finally, I should note that all this stuff will just barely fit on a 2 gig drive. I had to pare down my pictures collection a little but no big deal. Without my photo collection, it would probably fit on a 1 gig drive. Can you even find those anymore?

    Dear John:
    You mentioned how you manage what’s on your thumb drive, but how do you manage a whole gaggle of thumb drives?

    As a magazine editor, I get a lot of press releases and articles submitted on thumb drives and they are all over my desk with no way to figure out what is on each one.

    Do they make racks or boxes for them like they do for CDs and did for floppy disks? Is there a way to label them as to contents with more than just one line?

    I’ve wrapped mine in Post-It notes with “December backup” or “Microsoft Press Kit” scribbled on it, but they are still all over my desk, and sometimes the wrapper falls off.

    Any suggestions?

    Love, Jeanne

    Hi Jeanne:

    You bring up a problem that frankly, I’ve never thought of. I’m not sure what the answer would be. I published a magazine back in the early days of electronic publishing, and then my monitor, my keyboard, my printer, and everything else around was covered with yellow sticky notes and my desk was covered with floppy discs. Because floppies were so unreliable, I tended to move everything off onto the server (almost 1 gigabyte – over $4000 worth) hard drive farm that was backed up to tape several times a day.

    As I think about this problem, I think I would probably move all the data on the my hard drive, wipe the thumb drives, perhaps load an electronic business card and maybe a template for emergency medical information, and then hand them out like business cards or perhaps gifts.

    Probably the central point that I wanted to make in this entry is that a thumb drive can be used to store your emergency information in a form that emergency departments are increasingly aware of.

    Earlier in the week, as a matter of fact, I was talking to an ER nurse and queried her about her knowledge of thumb drives. She said that they had recently had a seminar on the subject. It raised awareness of the drives and the data they may contain.

    Coincidentally, I had taken one of my smaller obsolete thumb drives and set up an emergency information form that she could fill in with her favorite editor. I gave it to her, told her to fill in all the information, and put it on her key ring. She thought it a grand idea.

    Thanks for writing,

    John

    PS: Arthritis has finally gotten to my fingers to the point that typing is painful and difficult. I recently installed Dragon Naturally Speaking software. I spent the last week training it to my voice and this is about the second or third memo that I’ve “written” with it. Other than acronyms, I’ve had to make almost no corrections or changes. As soon as I learn the command language, I’ll even be able to handle them.

    If you type as much as I do, and I’m sure you do, you ought to give this package a look. It’s a Godsend for my fingers. Of course, if you work in a cube farm, people will think you very strange to be talking to yourself :-)
