Windows Vista crcdisk.sys – System Won’t Boot

I recently had a friend call me in need of computer repair assistance. I’ll save you the many hours of troubleshooting and simply list the fix here.

The Dreaded crcdisk.sys

I found this symptom of the problem by booting into Safe Mode and watching the drivers load. I noticed that it always hung for a long time on the crcdisk.sys file. Well, if you perform a search on Google for “windows vista crcdisk.sys” you will find a plethora of woes from computer users desperately trying to regain the functionality of their PC. There are also a plethora of fixes, advice and this worked for me posts. I tried many of these to no avail.

The Road To Recovery

The laptop I was working on was a Toshiba laptop and it had a system restore disk. Great! Sort of. Restoring the system to factory condition from the disk (after the owner had backed up their data of course) resulted in a system that was broken and still had the problem listed above. Hmmm.

Another operating system perhaps? I installed Windows XP from scratch. Worked great. I installed Windows Vista SP2 from scratch (another disk). Worked great. Re-tried the system restore from Toshiba. No good.

At this point I figured I was just going to install Vista from scratch. So I reinstalled Vista and downloaded the Toshiba drivers from their website. One by one I started installing the drivers. Until I got to the driver for a flash media card reader (front of laptop). Bam! It froze up during the install. So I rolled that change back using Windows System Restore and then continued with all of the other drivers. No problems. I tried the flash media driver one more time just to be sure, and sure enough it failed again. That’s good! Predictability is key in diagnosing computer problems.

Dump A MySQL Database To YAML Using PHP

The Problem

I was recently working on a project that is built on WordPress / BuddyPress. I built up some content using the CMS features of WordPress in my development server and then I transfered the WordPress content to a beta server using the export/import functionality. That kind of stinks having to do that every time I want to push updates to my beta server. So I looked into using Doctrine to generate data fixtures which I could repeatedly run against the different database. Doctrine supports YAML files, which are extremely easy to edit by hand, so it seemed like a good idea.

So what’s the problem? Well, I didn’t currently have any of my data in YAML files. I didn’t want to had edit them or do some sort of copy and paste madness. So, I wrote a script in PHP to dump my data into a YAML file.

Modify PHP CLI Include Path Dynamically

I was working with an application platform that I had just downloaded today. I just wanted to check it out and play with it a bit. In the application framework was an executable script that provided some command line utility. I fired up the script and received an error like “PHP Fatal error: require_once(): Failed opening required…”. Of course non of the files from the downloaded archived were in the include path for my system, but I didn’t want to just go adding it to my php.ini file just to play around with it short term. What to do.

Command Line Options

First I wanted to see if there was a command line option that I could pass to PHP to tell it what include_path to use for just this one execution. If you execute the following you’ll see the usage:
php --help
There is no include_path command line option, but there is the -d foo[=bar] option which allows us to modify any of the INI entries by key/value.

Mashable’s iPhone App – Flash What?

I just opened up the Mashable app on my iPhone to view an article and received the error below stating, “You need Adobe Flash Player 8 (or above) to view the charts. It is a free and lightweight installation from Adobe.com. Please click on Ok to install the same.” Hey guys… are you aware of the whole Apple / Flash controversy? I’m guessing your iPhone app shouldn’t be prompting me to install Flash.

Java’s Assimilation Into Oracle

Whenever I’m working with Java code I have a habit of opening up a web browser and going to http://java.sun.com immediately. From there I select the Java API Reference and away I go writing Java code. I did the same thing today and was a bit shocked that the Oracle brand has completely infiltrated the Java site. I knew Oracle had acquired Sun, but it wasn’t until today that I really looked at that reality.

Not that it matters much, but I thought it was interesting.

Upgrade Time : WordPress 2.9 and MySQL 5

WordPress 2.9 was release somewhat recently and so like a good WP minion I logged into my site and clicked the update button. Error… uh oh. Apparently WordPress 2.9 requires a more recent version of MySQL (>= 4.1.2). My host installed MySQL 5 ages ago but I’ve never bothered with migrating to the new version because I didn’t have a reason to. Now I do. So here’s how my upgrade went.

First I made a full backup of both the web content and the MySQL database. The MySQL database backup was just a mysqldump command like so:

Geek Gift Ideas – November 30

xkcd_book_300Some people have said that, “laughter is the best medicine.” Well, today’s geek gift idea is the gift of laughter; the kind that appeals to geeks in particular. xkcd is described as a webcomic of romance, sarcasm, math and language. This book, xkcd: volume 0, is the first book that combines selections of the first 600 comics, including various author and fan favorites.

The cost is US $18.00 and is printed by BreadPig. Another thing that makes this a really neat gift idea is that BreadPig’s portion of the profits will go to build a school in Laos through the charity Room to Read.
