How to check SSD alignment

If you didn’t align your partitions when you upgraded to an SSD, there’s a pretty good chance you’re giving up performance and life expectancy. Here’s how to check SSD alignment.

But first, a bit of good news. If you created the partition with Vista or Windows 7, your partitions should be aligned. If you upgraded from XP and didn’t re-partition the drive in the process, then it probably isn’t.

Get ready for some command-line jockeying and some math. Read more

Speeding up a sluggish HP Mini 110

My mom’s HP Mini 110 Atom-based netbook (with the factory 16GB SSD) was hesitating, a lot. Frankly it was really frustrating to use–it would freeze up for minutes on end, for no good reason. It was so slow, calling it “sluggish” was being kind. But it’s fixed now. I did six five things to it. Here’s how to speed up an HP Mini 110.

4 more questions about RAID

Longtime reader Jim ` asked me a few more worthwhile questions while I was procrastinating working on yesterday’s post about RAID. Let’s go to Q&A format. Read more

RAID 101

If you need an introductory course on RAID, here’s RAID 101 for you. Once exclusively used in corporate servers and by performance enthusiasts, the cost of hard drives and chipsets is so low now that RAID is showing up in consumer PCs. That’s good–as long as you set it up carefully. Read more

Completely bizarre computer problems? Check your system date

PC Magazine’s editor in chief wrote a long column late last week talking about his weird computer problems and a Quixotic quest to fix them. Among other things, his antivirus wasn’t working, and Windows wanted to be activated and wouldn’t let him. He thought he had a virus, but all his scans came up clean.

It turned out his computer thought it was 2013. The date and time were right, but the computer was trying to live three years in the future. Read more

What you need to know to safely replace or substitute AC adapters

AC adapters inevitably break or get lost. That means you have to replace them to get your devices working again. But a lot of people don’t know how to do that safely. Here’s what you need to know when you need to substitute AC adapters.

This is important. Getting it wrong can damage your equipment, the adapter, or both. The damage can be immediate, or it can appear over time.

The specifications for your AC adapter (also not affectionately known as wall warts or power bricks) should be printed on the old one, and hopefully on the device too. If you lost the adapter and the specs aren’t on the device, try a web search on “ac adapter specifications” and the name of the product.

It used to be you could take the device to Radio Shack, and $25 and five minutes later you had a good replacement. Today you might try Batteries Plus for a similar experience. But if you’re willing to do the legwork yourself, often you can find a close-enough match for closer to $10.

So, with all that said, here are the handful of things you need to know when you’re shopping for an AC adapter. The specifications don’t have to match exactly, but you have to know when you can cheat and when you can’t. Read more

Are Black Friday computers a good deal?

Black Friday is going to be here before we know it. And historically, that’s been a good day to snag a deal on consumer electronics. But does that hold for computers?

I’ve studied many Black Friday computers–I have two Black Friday specials from years’ past sitting in the basement as I write–and I have to say that when it comes to those, you’re getting what you pay for. Yes, they cost less than computers from September and October. But there’s a good reason for it. Read more

Predict your SSD life expectancy with SSDLife

Here’s a great tool: SSDLife. It helps you predict SSD life expectancy.

Back in the bad old days of hard drives with magnetic platters, you could only speculate about their life expectancy. With SSDs, life expectancy is a lot more predictable, and that’s what this tool does. Read more

It’s been 15 years, and computer stores haven’t changed much

In the early 1990s, I learned how to fix computers because I got tired of long waits and shoddy repairs from computer stores.

Last month I took a friend to go buy a computer. I didn’t want her to get stuck with retail junk, so I took her to a computer store that I knew sold quality parts. Plus I know the owner. He wrote an O’Reilly book too. I figured it would be a smooth experience, since I knew exactly what to ask for. The salesperson said he’d get back to me within two days with a quote, then it would take about a week to build the system after we gave the OK. Seems pretty smooth and reasonable.

It turned into a nightmare. Or at least a mess. Read more

Computer won’t boot? Check your USB ports

A friend called me in panic. A brand-new computer, freshly reinstalled with Windows 7, suddenly wouldn’t boot.

I couldn’t figure it out. I looked up the manufacturer’s 800 number and suggested she call. Sure, I could fix the problem eventually, but the manufacturer would know the quirks of the motherboard they used better than I would. I’ve given up on trying to give anything but the most basic, superficial support of anything I don’t own myself–especially when it’s not sitting in front of me.

He had her change the boot order. For some reason the system was trying to boot off its RAID array before the SSD. That explained why the system took a couple of minutes to get through POST, then spend a few seconds booting. But that didn’t fix the problem. Read more
