IDE #0 ERROR

Christine’s laptop has been a bit poorly lately. Before Christmas, it wouldn’t boot up – the ‘Starting Windows’ graphic would show and then it’d stop at BSOD with ‘Unmountable Boot Volume’ as the error. I was able to fix it by starting the computer in Windows Recovery Mode, opening a Command Prompt and using CHKDSK to sort out errors on the hard drive. That did the trick.

But this happened again last week. I did the same thing, but this time CHKDSK found a whole host of bad sectors. While Windows would then boot up afterwards, it was rather slow, and a white flag appeared in the bottom left of the screen, telling me that Windows was having problems with the disk. Not good.

Rather than risk any further disk problems, and Christine losing all of her files, I bought a new hard disk to replace the old one. I took the old disk out (thankfully not too difficult a task with her laptop – an Acer), and put the new disk in, then put the old disk in a USB enclosure. Next, I downloaded CloneZilla and burnt it to a blank CD, then booted the computer up using the CD and had it clone the old drive onto the new drive. I had to run it in ‘–rescue’ mode, as when I tried it with the default settings it failed when it hit the bad sectors. Copying the data took around 6 hours, as this was a 640 GB hard drive.

Thankfully, it was a success, and the computer now boots up and runs fine. The new disk is a 5400rpm 640 GB Samsung drive, which is of the same specification as the old disk – a Western Digital Scorpio Blue (which apparently isn’t very good). I did look at a 7200rpm drive, but would have needed to wait longer for it to be delivered – this drive was available immediately.

Having suffered from a major disk failure back in October 2004 (when some irreplaceable data was lost forever), I’m keen not to replicate the experience in a hurry.

What the cool kids are using

I don’t mention my job here much, mostly because the majority of the work that I do deals with confidential information about students and applicants. But today, for a change, I spent some time invigilating a group practical assessment for some of the science students, and the majority of students had brought their laptops with them (it’s ‘open book’, so they can use textbooks and the internet).

Whilst making sure that none of the students were cheating, it was also a chance to see what laptops and web browsers they were using.

Most students had normal sized laptops, but around a quarter had the smaller netbooks. The vast majority were running Windows Vista or 7. Three or four (around 5%) were Macs. There were also a couple of iPads, plus various students using the internet on their smartphones.

As for web browsers, Internet Explorer stuck out as the most popular, though at least everyone was using version 7 or later. Interestingly, Google Chrome was the second most popular, with a surprisingly high number – probably 15-20% of people. Remember, these students were studying science, but not computer science. Firefox was in third place, and I saw one Opera user too. Almost everyone had multiple tabs open; some had 5 or 6.

If this is a typical sample, then it may be that I’m underestimating how popular Google Chrome has become. It’s still quite new on the scene but its growth has been huge.

(Usual disclaimer: this does not necessarily represent the views of my employer, this data was not gathered using scientific methods etc.)

New laptop

I’m spending the weekend at my parents’ house in York and so my duties as the person who knows about computers come into play. This usually involves ensuring that all the software on my parents’ computers (a shared desktop and my dad’s laptop) are up-to-date, and fixing any problems that have arisen since my last visit.

This time, my dad has a new laptop.

I helped him buy it from Amazon. A Mac laptop was ruled out early on, since Apple don’t do an affordable MacBook with a reasonably large screen (this is something Microsoft touched on in a recent TV advertising campaign). He wanted something bigger than the 13″ screen that the MacBook comes without paying £1299 for the 15″ MacBook Pro, which would also have been overkill for what he needs it for.

So we were looking for something running Windows. I suggested waiting until Windows 7 had come out, so we did. I also suggested going for a computer with a 64-bit processor and the 64-bit edition of Windows 7. While it may result in some incompatibilities with very old software, I believe that we’re now at the tipping point where 32-bit computers and software will go out of fashion and only serve the low end of the market, with 64-bit machines taking over the mid-range. It also means that the computer would be upgradable beyond the 3 GB of RAM that it ships with.

Ultimately, he settled for a HP laptop from Amazon, costing £450. It has an AMD Turion II dual-core processor, 320 GB hard drive, Windows 7 Home Premium 64-bit, DVD Rewriter drive and a few other bells and whistles like a remote control for Windows Media Centre, an HDMI port and an eSATA port which also doubles up as a fourth USB port. In terms of ‘crapware’ it wasn’t too badly inflicted – an AOL toolbar and 60-day trials of Norton and Office 2007 – all swiftly removed.

For the anti-virus I gave Microsoft Security Essentials a go, and it seems to work well as a simple, unobtrusive anti-virus program. It may not have the fancy features that Norton and McAfee offer, or even some of the features of the likes of AVG and Avast!, but it seems to do the basics very well, without monopolising a significant amount of computer resources.

Buying a computer with Windows 7 pre-installed ensured that we avoided most of the potential driver faults, though it still seemed remarkably stable (so far). The refinements over Windows Vista are subtle, but welcome, and it’s definitely a leap forward over Windows XP. Installing a printer connected to another machine running Windows XP was as painless as it is on a Mac – all you have to do is tell Windows you want to add a printer, say it’s on the network and it’ll present it to you in a few seconds – and then it’ll download and install the drivers for you automatically. That’s how easy it should be.

Speed-wise it’s very fast. Obviously it’s fresh out of the box so no doubt it’ll slow down over time, but installing software and indexing photos have all been very quick, even when running 32-bit programs. I’ve not noticed any incompatibilities when running 32-bit software on it either.

I have to say I’m quite impressed at how good the machine is, considering the price, and Windows 7 is living up to some of the more glowing reviews I’ve seen of it. Still…. I think my next computer will be a Mac. As much as I like this laptop and Windows 7, I’ll stick with Apple build quality and design, which is still ahead of HP and Microsoft in my view. Not by as much, but still ahead.

Officially an adult

It’s my 18th birthday!!!

Yup, I’ve turned the big 1-8 today. Marissa (my new laptop) is now up and running, though admittedly not under Windows. I decided to go ahead and install Mandrake 8.2, and I’m very impressed. The CD autoran in Windows, and gave me the option of either booting from the CD (didn’t work) or creating a boot disk and using that. Although the boot disk creation was a little difficult (I had to read the documentation to find out what to do), it was done quickly and I was able to boot into the installer.

The installer was great – the ‘express’ option take about 30 minutes and was nice and easy to understand – there was plenty of help available and no confusing dialogs. The partition manager was excellent, though I did have to say goodbye to Windows XP due to the fact that Samsung had chosen to use NTFS, which, although it is recognised by Linux, isn’t supported. But it is a new system so I wasn’t going to lose anything.
I’m using KDE as my desktop – not KDE3, since this isn’t yet included – but 2.2.2 (I think). It also comes with a full office suite, more web browsers than you can shake a stick at (including Mozilla, which loads much more quickly than its Win32 counterpart) and various other tools.

There are down sides – I couldn’t get the sound to work, and I won’t be able to use the internet for a couple of days until NTL get their act together (I’m on Marianna, the old machine), but on the whole, I’m pleased with what the Open Source community has done here.

My other presents included a laptop backpack – or rather the money for it, though I got one today from PC World. It’s great – not only will it carry the laptop but the transformer, extra mouse (which also works in Linux, despite the fact that it is USB and has a wheel) and Ethernet lead, and a great deal else. I also got a wallet (to complement my proof of age card, which arrived this morning – nice one, Portman Group) and more money. The rest of my presents will be here tomorrow when my grandparents and cousins come over for dinner.
Anyway, I’m off out for my birthday party. See you later!
