Active@ KillDisk makes a decent free drive wipe utility
, good free drive wipe utility
, tips for proper drive disposal
I’ve recently finished work on a forthcoming book about phishing attacks entitled Cyberheist, and have also updated my CISSP Study Guide and Computer Forensics JumpStart titles in the past three months. If there’s one lesson I’ve absorbed into the marrow of my bones as a result of these projects, it’s that unleashing old disk drives to others is an invitation to security disasters. That’s because a competent forensics analysis of a disk drive — even one that’s been erased and reformatted — can turn up all kinds of interesting remnants of its former contents for anybody who has the right tools and knows how to use them.
Thus, when I found myself in the situation of needing to recycle some old disk drives that “the boss” (my wife, Dina) told me needed to get themselves gone from our house, I turned to the Internet to find a usable drive wipe utility that would perform an acceptable drive wipe on some drives that never had financial or other sensitive information written to them (those I would crush or incinerate). After a few false starts that showed me that you really have to try out a drive wipe utility for yourself to see if it does what you want it to (wipe an entire drive clean, in my case), I settled on the free version of a tool named Active@ KillDisk to do the job (the free version does a one-pass erase only, the $49.95 Windows and $59.95 Suite versions support 17 different standard drive-wipe algorithms). The drives in question contained photos, music files, and archives of books and other writing projects, so I wasn’t overly worried about accidential disclosure anyway. Users with more sensitive data should probably take the “crush or incinerate” route, or purchase a commercial drive wipe tool that does multiple erase passes (the DoD recommends a minimum of seven “erase and write random data pattern” passes over a drive to consider it “clean for re-use” — they also recommend “crush or incinerate” for proper drive disposal too, BTW).
Here’s what the GUI for the program looks like:
Program UI shows it is easy and straightforward to use
I mounted my old drives into USB enclosures, plugged them into a laptop USB port, fired off the program and let it chunk all night to wipe each of the two 3.5″ PATA drives I’m taking to Goodwill this coming weekend. Safe enough for non-sensitive data, and easy enough to use, though very time consuming (22 hours for a 200 GB drive, and 29 hours for a 300 GB drive). Check it out!

Easy workaround for Silverlight update failure: uninstall old version then install new one
, Latest Silverlight Security Update Hangs "The Dragon"
With six or seven computers around my office at any given time, in various states of (dis)repair, I find myself devoting at least three or four hours a week to system checkups, diagnoses, updates, and repairs or upgrades. When something like Windows 7 SP1 comes along that number hits a temporary spike but otherwise, this is a pretty consistent number (it also includes fiddling with new programs, drivers, and other aspects of PC maintenance).
This weekend, I cranked up my favorite problem child PC, an HP HDX 9203W (aka “The Dragon”) for which HP doesn’t support Windows 7 (they stopped updating software for this machine at Vista). When I ran my usual weekly Secunia check, I realized this machine had been off since before last Patch Tuesday (March 8th) because a slew of updates was waiting for me to install on that machine, including the ultimate Patch Tuesday (PT) tip-off, the Windows Malicious Software Removal Tool x64 – March 2011 (KB890830). But every time I tried to run the whole batch up updates en masse the update process would hang and never even get to downloading files. In other words, something in the batch was causing the update process to fail.
I started knocking off the March PT elements one at a time. All of the important updates went through single-file without a hitch:
- Update for Windows 7 for x64-based systems (KB2524375)
- Update for Windows 7 for x64-based systems (KB2505438)
- Security Update for Windows 7 for x64-based systems (KB2479943): This is the one that Secunia noticed was missing, and what clued me in to the need for a visit to Windows Update.
- Windows Malicious Software Removal Tool x64 – March 2011 (KB890830)
March 2011 Silverlight Security Update would not install
It was the optional update for Silverlight [Security Update for Microsoft Silverlight (KB978464)] that was hanging. Next, I tried a couple of different installation techniques: by itself from Windows update, then from the standalone KB download link, both without success. Along the way, Windows 7 continued to perform the installation after I triggered a system restart with a new pre-shutdown message “Installing update. Do not power off your PC until installation is complete.” No dice for any scenario.
After reading up on Silverlight, I learned that MS issues a new version of the install executable each time it issues a Silverlight update. So I used a workaround to fix the problem instead: I uninstalled the old version that I couldn’t patch for whatever reason, then simply installed a brand-new version with changes already incorporated. This went without a hitch, and Windows Update even gave the system a clean bill of health when I performed a post-install check to make sure everything had worked as it should have. I’m still not sure why the Silverlight update wouldn’t install on the Dragon, but at least I found a way around that problem and have caught the machine up. It will be interesting to see if I need to go through the same manuevers the next time a Silverlight security update hits.

Firefox 4 downloads blow IE 9 completely away
, Firefox 4 first-day tally double IE 9's take (4.7M vs 2.35M)
Holy moly! Firefox 4 hit the streets on Tuesday, March 22, and quickly blew away IE 9 download numbers from the previous week. By the end of the first day, the count topped 4.7 million (ahead of IE 9′s 2.35 million in its first 24 hours, as tallied in this CNET story), and it topped 10 million by the end of Day 2 (Wednesday, 3/23: PC Magazine reports that it hit this milestone by 4:30 PM Eastern time that day). As I write this blog, the number at the FireFox 4 Download Stats page is climbing up from 24 million, as shown in this screen cap:
On Friday, 3/25, the download count topped 20 million
That’s an impressive daily run rate so far. Already at just after 9 AM CDT (-06:00 UCT) the daily average is over 6 million for the first four days, and with 15 hours left to go in that day, it could conceivably wind up somewhere between 7 and 8 million per day by the time the clock hits midnight (a straight-line extrapolation says it will be just over 7 million but that doesn’t factor any acceleration in). But the current tally clearly demonstrates that the daily rate is accelerating from day 1, and might conceivably go as high as 175% of the first day’s numbers by the end of today, day 4. This may not wind up as high as the 8 million copies of Firefox 3 downloaded in 2008 on its first day outing, but it’s certainly sustaining itself quite nicely.
In seeking to explain why Firefox is zooming past IE9, the aforecited PC Mag article provide an entirely credible hypothesis that with over half of all PC users still running Windows XP, Firefox 4 has a much bigger audience than IE 9, which runs only on PCs with Windows Vista or Windows 7 installed (Vista’s market share is now just over 11% and Windows 7 is clocking in at just over 23%, but XP still enjoys a market share of over 55%, according to today’s Operating System Market Share numbers at Netmarketshare.com). What that really means is that the total percentage of users that Firefox 4 can reach is almost three times as large as the one IE 9 can serve. Seems like an entirely plausible analysis to me!
I’m running Firefox 4 on several machines now, and I already like it much better than version 3.6.3 I had been running previously. It’s more streamlined, and much faster than its predecessor. With snappy svelte new versions of Chrome, IE 9, and Firefox 4 all recently on the streets, the browser game has certainly picked up lately, hasn’t it?

IE9 launches at SXSW with interesting video
, IE9 sets download record for first 24 hours
As of March 16, Ryan Gavin at Microsoft reported that IE9 more than 2.35 Million downloads of IE occurred in the first 24 hours following its release on Monday night, March 14, 2011. He also reports that this works out to 27 downloads every second over that period. Wow!
These numbers represent more than double the download rate for the IE9 Beta upon its release, and quadruple the rate for the IE9 Release Candidate as well.
So far, I’m running IE9 on a single machine in my office (on my HP i7 quad core notebook). I’m still learning how to drive the UI and haven’t quite learned all the ins and outs yet, but I can say I like the more compact layout better than IE8. It also runs perceptibly faster than IE8 does on equivalent hardware. It still doesn’t keep up with the latest Chrome in its support for HTML5, though matters on that front have improved somewhat. I’m going to take this one slow and get to know the program better before I roll it out to all my machines.

, and learning
, keeping up with patches and fixes requires occasional thought
, Secunia's automated updates don't always work for various good reasons
I run Secunia PSI on all of my networked PCs (which means “all my PCs,” in fact). Every now and then, the program smacks me with forcible reminders of how interesting it can be for network admins to keep up with an ever-changing landscape of patches, fixes, and updates.
As the updates hit, my synch level has had some misses lately
Two cases in point on my production PC this morning:
- Secunia informed me that my Citrix WebApp plug-in was out of date and that a newer version was available. But because I’m not a licensed Citrix user at present (I was working as a contractor for a chemical company last year, and got the plug-in from them so I could use their VPN) I wasn’t able to download the latest version (no license, no access, as is perfectly understandable). I ended up having to find the directory in which the plug-in resided, and then having to manually delete same, to clear the warning on my machine. No big deal: I’m not using it anymore anyway.
- Secunia also let me know that a new version of Chrome 10.x was out (and wow! the first one only shipped last week: those Google guys move fast!). I clicked the About menu entry in the program and it informed me that Chrome was up-to-date. So I had to go to the Chrome download page, then download and install the latest version to clear that warning.
It just goes to show you that when it comes to keeping up with software updates, it’s not always a push-button, completely automated affair. Sure, Secunia will indeed update lots of stuff for you, but there’s always something that automation doesn’t catch (my lack of Citrix download access on the one hand, and Chrome’s refusal to recognize it needed updating on the other). That’s when an admin has to step in, figure out what’s broke, and fix it the old fashioned way: diagnosis, analysis, repair, and post-assessment. I guess we should all be glad: otherwise, somebody in Pune or Hyderabad would be taking care of my machines for me, and I’d be out of a job.
[Note to the wonderful folks at Secunia, whose PSI is a real Godsend to me: my final remark about being out of a job is purely metaphorical, all my systems are in my home, and not part of a commercial enterprise. Please! Don't take my licenses away.]

change Windows 7 default restore point behavior
, managing Windows 7 restore points
, various ways to capture system state at a frequency and time of your choosing
In reading Michael Horowitz’s “Defensive Computing” blog on ComputerWorld this morning (it’s entitled “Windows 7 Restore: less trustworthy than XP?” I was reminded how things can go wonky in a hurry when Microsoft changes its rules for system behavior. And for those who didn’t follow along from XP to Vista and thence to Windows 7, some of those rule changes can lead to some nasty surprises along the way.
Case in point: automatic system restores in Windows 7. As Horowitz quotes from MS documentation in his blog “System Restore in Windows 7 creates a scheduled restore point only if no other restore points have been created in the last 7 days.” XP makes restore points every day by default schedule, so I can see where dropping down from daily to weekly might be problematic, especially on volatile test systems where getting back to a stable state will be easier if users can expect restore points to be less than a week old.
I have several things to say about this phenomenon:
- It’s good to be aware of this default, and to make changes if it doesn’t work for your needs. One way to do that is to check out the How-to Geek’s instructions “Change How Often System Restore Creates Restore Points in Windows 7 or Vista,” where you find step-by-step instructions for using Task Scheduler to create Restore Points at a frequency and time of your choosing. Another way to do this is to use some kind of virtualization tool to run volatile OSes, which may then be captured with regular snapshots.
- When Windows 7 (or Vista) makes an image backup using the built-in backup utility, it captures a restore point at the same time it makes that backup. By scheduling image backups at a higher frequency than once a week, you’re guaranteed to do likewise for restore points. Here’s a screen cap from one of my fairly busy test machines that shows that both automatic and image backup restore points can be collapsed into a single snapshot (see first two entries below).
Various restore points from a busy test PC
- I’ve been messing about with boot/system drive SSDs for over a year now, and I’ve learned to flout conventional wisdom and/or typical advice to turn off System Restore for such drives. Yeah, sure, it means more writes on those drives and probably a shorter lifetime, but I’ve learned the hard way that the convenience and quick fixes that restore points can deliver outweigh the extension to drive life that turning restore points off for SSDs can afford. Besides, I’m pretty sure I won’t be using those drives for more than 3-5 years anyway, and the “10,000 write limit” should last quite a bit longer than that.
When it comes to Windows 7 restore points, if you don’t like the default behavior, you can — and probably should — take steps to change it. Then you won’t have to be unpleasantly surprised to learn that your most recent restore point is 7 days old, because you can take steps to ensure it will never be any older than whatever frequency you schedule for restore point creation (using Task Manager, or some other automated scheduling tool) or system image backups (using the built-in utility).

MS beefs up its app virtualization offerings and adds new Thin Client OS
, Windows Thin PC lets legacy PCs be repurposed as Windows 7 thin clients
At yesterday’s Microsoft Desktop Virtualization Customer Roundtable, the company soft-announced a beta date for Windows Thin PC (aka WinTPC) some time before the end of March, 2011. This is a locked down, small-footprint version of Windows 7 designed to permit existing PCs to serve as thin clients. (You can see a fascinating video about this event on the Desktop Virtualization home page, including an on-cam interview with Microsoft Windows GM Gavriella Schuster, as she walks viewers through a raft of customer success stories on this technology.)
Microsoft has now instituted GA (general availability) for App-V 4.6 SP1 as well. It’s intended to make virtualizing applications faster and easier. The latest release includes “package accelerators” to simplify and speed up the app virtualization process, and deliver those virtualized apps over their network infrastructures. These package accelerators should be available in early April, with tools for Adobe Reader, Office 2010, and Microsoft Project planned among the first such offerings.
At the same time, Microsoft Enterprise Desktop Virtualization (MED-V) version 2.0 is also in GA status. This technology permits IT professionals to package up and deliver legacy applications inside VMs that can run on Windows 7 through direct desktop integration (packaged apps run from icons on the desktop or Start Menu entries, though their runtime environments operate inside VMs running older MS operating systems, typically Windows XP). This latest release includes improved linkages with System Center Configuration Manager as well as various third party solutions.
Of course, these technologies are available only to customers who have purchased Software Assurance (SA) licenses or a Virtual Desktop Access (VDA) subscription. For more information, see Dan Kuznetsky’s exellent ZDNet blog (“Virtually Speaking”) entitled “Microsoft Announces Windows Thin PC and Both App-V and MED-V Updates” or Kurt Mackie’s February 16 story for “the Journal” entitled “Windows Thin PC Details Revealed.”

faint glimmers of hope in latest BLS Employment Situation
, general IT hiring boost remains in the offing
, NPR reports a radical surge in hiring for programming jobs
Finally! The latest Employment Situation Summary from the US Bureau of Labor Statistics released this morning shows some welcome and long-overdue signs of improvement in hiring numbers. But although nonfarm employment numbers jumped by 192,000 for February, the unemployment rate stands basically unchanged at 8.9 percent (employment gains from hiring were offset by unemployed persons once again looking for work, thereby boosting the overall employment pool). The big job gains occurred in the following sectors: manufacturing, construction, professional and business services (good news for IT contractors and consultants perhaps, if not for the entire information sector at large — more on this in the next paragraph), health care, and transportation and warehousing. Of course, we need to see monthly numbers jump by 100,000 or more above this level to really make a dent in unemployment, but good news is still good news in this troubled part of the economy.
Header for the February 2011 Employment Situation Summary
On NPR this morning, I heard a story that was much more encouraging for beleagured IT workers. Zoe Chace filed an item entitled “Want A Job? You Ought to Be a Tech Geek” In it, she recounts how upcoming and recent IT graduates with programming expertise are finding themselves in the unusual and welcome position of having to decide among multiple offers — sometimes as many as ten or more per job candidate — when it comes to choosing an employer. A strong demand for mobile app developers (there’s a surprise, eh?) is fueling this hiring frenzy, but it’s a strong showing for what has been a grim job market for recent graduates since the economy hit the skids in 2008.
Now, if only that frenzy could extend as far as rank-and-file IT jobs, the doldrums might finally be behind us. My best guess, however, is that we’re at least 12-18 months away from the kind of rising tide that is likely to float all hiring rates higher, especially for cost-center/infrastructure functions like IT. Hang in there, IT troops: looks like the first faint glimmers of improvement are finally heading our way!
