IBM DeathStar / Down in the Dumps

I don’t usually write about my mood, but today I woke up feeling really down. Thankfully, I haven’t been sent into massive panic attacks over the issues described below. (One of the ironic points of living with an anxiety disorder and being a computer Geek is that a trigger point for my anxiety is problems with my own personal computer.) I am grateful that God convinced me to make a critical backup at just the right time, so everything important is intact and backed up.

It looks like I’m going to have to replace the old IBM drive on my primary computer. I noticed last night that it was an IBM DeskStar drive, which my friend Charlie Dunn said was so prone to failure they nicknamed them “DeathStars” when he was working in IT.

At first it looked like I had a problem with overheating—and that still may be the problem—although it seems to be getting worse. Last weekend Nichelle compalined that her e-mail was missing for a period of several months, but after rebooting the computer, everything was fine. I took the precaution of backing up our photos (most of which are already on CD as yet another backup), financials, and documents folders to a nonused partition on a drive I’d added in December.

A couple of days ago, I logged in to the computer and was notified that numerous updates were ready to be installed to Java and Windows XP. These updates had already been installed, and it was rather obvious what had happened—the primary drive, from which we have been booting for nearly all of the lifetime of the computer had disappeared, and the machine rebooted to an imperfect Windows setup on the second drive. (That setup was toasted, apparently, by a bad power supply, now replaced, that caused some data loss.)

Part of the time the IBM drive isn’t being recognized at all. After a certain amount of time—perhaps due to overheating, perhaps due to another type of drive failure, it won’t be recognized at all. Rebooting the system sometimes catches it and boots to the original drive, especially if the whole system has been off for a while. On a really hot day, or after a period of high disk activity, the drive will fail again and the system will reboot to the bad partition.

I’d like to try copying the image over to a new drive, using Ghost or whatever comes with the new drive (I’m leaning toward Seagate), as it would get me instantly up-and-running without having to reinstall. Of course, I do not have that much hope that the old drive will “hang in there” long enough for such a data-reading-intense operation to happen.

If that doesn’t work, I’m willing to bite the bullet and do a reinstall of XP Pro. However, there is a drive size limitation (I think it’s 120 GB) in the initial release of XP Pro (pre SP-1), which is what I have. Installing from an SP2 CD would be even sweeter, and less prone to failure than upgrading to SP2 from a previous version.

:: sigh ::

Editor’s note added June 13, 2005:

It looks like the drive is only flaking out when it overheats. I think it may fail soon, but letting it cool down with the machine off so far makes it recover. In the mean time, I’m keeping my data backed up daily, and when the drive does fail, I can boot to my “February” installation, and still run all my apps, so replacing the drive is now less urgent, and I can plan for this at my convenience.

Editor’s note added June 21, 2005:

No, it’s not necessarily related to overheating. Or, if it is, the drive is “overheating” at a temperature far below what its temperature sensor would indicate shoud be a problem.

Last night I was running at a reasonably cool 35 degrees C, when the whole things went kablooie. At first I had the usual trouble recognizing the drive. Then, when I finally got it to recognize, it was dog slow, and told me that Windows couldn’t boot because windows/system32/system was missing or corrupt. I had just finished backing up everyone’s e-mail, pictures, etc., except mine.

This morning, after leaving the system off overnight, I got the drive to be recognized by leaving it running for a few minutes, and everything seemed to be fine.

So heat may be playing a factor, but I think it’s time to just retire the drive.

I’m also looking at putting together a new system that would kick butt for as little as $500, but I also need to get this one back to a reliable state.

Editor’s note added June 27, 2005:

Wednesday night after church, I went out and grabbed a 120 GB Seagate Barricuda drive to replace the boot drive. On Wednesday, the IBM DeathStar drive seemed to fail completely, and I was looking at rebuilding my system.

On Thursday evening, I decided to give the IBM drive a few more tries, and got it to recognize at startup!

Hurriedly, I rebooted with the Seagate drive, hoping to be able to copy my IBM drive over to the Seagate drive, which would become the new boot drive, and save me from having to reinstall everything.

Seagate’s drive setup software is supposed to be easier to use than Western Digital’s. I actually didn”t find that to be the case. They both are about the same, but there were some nonintuitive points that I had to keep hitting the help file and documentation for. Once nice thing (which I did not need) is that Seagate lets you print installation instructions that are customized for what you’re actually doing.

It took hours for the drive to copy, mostly due to the read errors (all were being corrected, but it was having to perform each read multiple times) that SMART was reporting. Copying also appeared to be slow because of Seagate’s verification process, but getting an exact drive copy is far more important than getting a fast copy.

I only found three problems:

  1. Trying to access the System Restore tab crashed. It turned that is always caused by a drive copy process, and all I had to do to fix it was disable the System Restore service, then re-enable it.
  2. The next problem was a missing FrontPage icon (the link would work, but the icon itself was the default rectangle). It was looking for something under installs that clearly wasn’t around any more. I simply replaced the shortcuts with new ones.
  3. Lastly, the icons on my own logon are weird. Unless I run in 32-bit color mode, I get ugly 2d, 8-bit icons. It seems to happen only on my account. I find it disturbing, but it can’t be described as much more than a cosmetic issue. Some of the menu colors are off as well. Again, it’s no big deal, but it does bother me.

Other than that, the machine is working perfectly. My friend Phil Luchon came over and brough his machine. We played WarCraft and StarCraft. The Lego Star Wars game, which the kids play every moment we will allow (one hour on weekedays, 2 on weekends), which had been very prone to crashing and lockups, has not had a single failure in 3 days.

Everything involving disk access is much faster on the new drive: booting, loading big programs, virtual memory swapping, etc.

So, You Wanna See Star Wars in Digital?

There aren’t very many digital cinemas, nationwide. There were 83, if memory serves, when Star Wars Episode I opened. We were fortunate enough to live near one.

Try this digital cinema finder, from Texas Instruments, the folks who bring you DLP, to see if there is one near you.

DLP is, quite frankly, an amazing improvement over film. I have heard that there are some theaters with a newer DLP projector that has even higher resolution.

Late for Work? Blame Your Car’s Software!

According to Reuters News, the Toyota Prius hybrid may have a software glitch that causes it to stall out.

Because Reuters does not make their articles available after 30 days, here is the text of the article:

Toyota investigating Prius stalling complaints
DETROIT (Reuters) – Toyota Motor Corp. said on Monday it is looking into complaints in the United States that its popular Prius hybrid car suddenly stalled or shut down, often at high speeds on highways.

“We have been alerted to the fact that some owners might have a problem,” Toyota spokesman John Hansen told Reuters. “We are going to go back to our service records to find out what owners have had a problem like this and how many.”

The U.S. National Highway Traffic Safety Administration said it has received 13 complaints so far of the gas-electric hybrid vehicles stalling or stopping unexpectedly.

Toyota dealers attributed the problems to a software glitch in the car’s complex computer system, according to some complaints.

NHTSA spokesman Rae Tyson said the agency is monitoring the complaints but that no formal investigation has been launched.

Toyota has sold 34,225 Prius cars so far this year. There is usually a waiting list to buy the vehicle, which has a gasoline engine with an electric motor to increase fuel efficiency. The Prius gets as much 60 miles per gallon of gasoline.

The Great Gasoline Boycott

You may have received an e-mail encouraging you to boycott, for the next year, two major gasoline vendors (click for a sample), to help achieve lower gasoline prices.

It is an interesting idea—certainly better than the “don’t buy gas for one day” e-mails that have gone out—but it can't work, from an economics perspective.

There are two major factors affecting gasoline prices. The first is the price of crude oil. The second is demand on gasoline itself.

Currently, crude oil production worldwide is at or near a maximum, reserves are shrinking, and much of the oil obtained is less desirable (and more expensive) for use in gasoline production. In addition to decreasing supply, the rapid growth of industry and the middle class in China is rapidly increasing demand on crude oil worldwide. Crude oil prices are going to continue to increase until production increases significantly or demand decreases.

Then there is supply-and-demand for gasoline itself. Worldwide, refineries, which convert crude oil into gasoline and other petroleum products are typically operating 24/7. This means that gasoline production is at its maximum. Due to environmental and security issues, few, if any, communities are willing to allow refineries to be built in their areas, and refinery construction can't happen overnight in any case.

Do we really think that gasoline companies are inflating prices by 100%? They are making a profit, to be sure, but certainly not at that margin. (Ironically, considering the e-mail I received, our local Hess station—one company targeted by the boycott—is typically charges 10¢ per gallon less than its competition.)

If we are to reduce the price of gasoline, we must decrease the demand. This can be done via carpooling, using public transportation, and buying hybrid or elecric vehicles. (Another topic is why the hydrogen fuel-cell powered car is a bad idea, but I'll save that for another time.)

It is estimated that gasoline will have to stay consistently over $3.00/gallon before people will stop buying the worst offending SUVs (some of which get as few as 7–8 MPG) and get something more fuel-efficient. (Many SUVs do much better, and the average MPG for an SUV appears to be over 20 MPG. My thanks to Robert Hardman for correcting my original misstatement.) I'm ashamed that our minivan only gets 20 MPG around the city, but our choices were limited by the need for space for our 4 children and personal economics. If we did not have a daily need for a larger vehicle, we would not have bought one.

What we ought to be doing is forcing the government to make its fleet vehicle purchases electric-gasoline hybrids or straight electric, demanding increases in public transportation allocation, subsidizing hybrid vehicle purchases (and other energy-saving projects) through tax breaks, and building more nuclear plants—which the US has a near-perfect safety record in operating, and which do not contribute to global warming or other air pollution—to supplement or replace natural gas-, coal- and oil-fired plants.

Anyway, that's my typical more-than-2¢.

(Thanks to Maryjane Case for the topic suggestion.)

And That’s … Bad?

The following is an excerpt from a Reuters Article (which probably won’t be available a month from now). I say, anything that gets kids to stop watching television is probably a good idea.

Commercial Leaves Kids Too Scared to Watch TV

LONDON (Reuters) – A Marmite commercial that parodied 1950's science fiction film “The Blob” has been banned from all children's' programs in Britain after leaving kids too scared to watch television, the advertising watchdog said.

…

Six people complained to the Advertising Standards Authority (ASA) that their toddlers had been terrified by the adverts, with four refusing to watch television after seeing them and two suffering nightmares.

I am amazed at how early children can identify with what is on television. One evening Naomi, at age 16 months, picked up her paper “Zoo Pals” plate, held it vertically in front of her face, and hummed a little song as she rotated it back and forth slightly. Nichelle told me that Naomi was mimicking the commercial.

Naomi is also enthralled with “Blue’s Clues,” and David, somewhat reluctantly, had to share his stuffed Blue dog with Naomi until Nichelle was fortunate enough to find one costing only a few dollars for Naomi. We have some old episodes on tape, and Naomi loves the program. Singing the theme song (which I do very poorly) is enough to get her dancing. I find this impact of television both fascinating and a bit frightening. (By the way, if you have heard a rumor that Steve Burns, the original (and best) host of “Blue’s Clues,” is dead, then you have been misled.)

Warning: I Am Posting Something Nice About the IRS

We, like many Americans, are waiting for our tax refund from the Treasury Department. I was poking about the IRS Web site, and discovered an online tool that will tell you when the IRS received your return, and when your refund check will be mailed. Give it a try!

Of course, I lean Libertarian (although I understand the needs of a Federalist system), so I want much more of my tax money back, but that’s a different topic.
