USB Shorts

From time to time we get called out to our CD ripping clients to help out with computer problems, which is where I've been this morning. The problem sounded simple, after years of normal service our client had plugged in his iPod and his PC had promptly died.

It's something he'd done, well, hundreds of times with no problems. Naturally he assumed that something in iTunes had corrupted his computer and Windows Vista. When I got there the PC was completely dead, as if the power supply had failed. So I checked the power cable, tried the cable from their kettle, no problem in the mains. Screen worked OK, just when you hit the on button absolutely nothing happened. My line of thinking was that this was a dead PC and the only way forward would be a new machine.

The client asked if the iPod had killed the PC or if, even worse, the failure had blown up the iPod. I should explain it was sitting unhappily on his desk. I thought I'd try it in my MacBook just to be sure so I lifted it up to unplug it. As I moved the iPod there was a flicker from the cooling fan inside the PC. I unplugged the iPod (which was undamaged), then unplugged the sync cable. Each move caused a tiny burst from the box. Having unplugged the sync cable I got a real burst of power so I tipped the box up and had a look at the front USB ports.

At that point I could see the cause of the problem. The tiny piece of plastic in the USB connector had broken, exposing the metal prongs that allow data and electricity to flow down the cable. Then, I'd guess when our client put the cable into the port, the prongs had been bent resulting in one of the prongs touching the metal surround.

A dead short.

I dug out my trusty metal comb which was slim enough to be able to lift the offending prong from the surround. At which point the PC burst into life. One happy client.

The CD Ripping Scene in Lion

As a CD ripping service we use a mix of Windows (XP, Vista and Windows 7) and Mac computers so the recent announcements are interesting. Would you like to jump in?

First, Apple's new operating system, code named Lion. Available for download now for a bit over £20 from the download store. A host of great new features. But ... Not all software will run happily under Lion. For example the Sonos controller program does not yet work with Lion so if you have a Sonos system hold on for the moment. Sonos have said there will be a new version but I don't have a due date. Some software may not run (older versions of Photoshop included) so if there's anything you rely on check with the vendor to make sure a Lion variant is out there.

Second, no CD drives. Neither of the new computers have a CD or DVD drive. This effectively stops CD ripping on those units - unless you have a free standing USB connected drive.

Apple Drops CD Ripping

OK, that’s an hysterical headline, an exaggeration. But just a bit.

Apple has launched a couple of new computers, a great new entry level laptop and a replacement for the trusty Mac Mini. I have a great affection for both. I’m writing this on a MacBook and my main production machine is a trusty Mac Mini. Just love Apple and Mac. Very tempted by the new boxes when I saw them. But ...

Neither machine includes a CD drive. Looking at the Apple store they still list the add on of the superdrive (at $80) but the product description suggests in the case of the Mac Mini it only connects to the version running Lion Server. Don’t worry about the details just note that’s the most expensive variant.

For the typical Mac user, by the way I’m off to see one on Monday assuming their new MacBook arrives, this means they won’t be able to rip CDs. As a CD ripping service you might think this is great news for us, and indeed it may be, but it’s also yet another nail in the coffin of the humble CD, another barrier to realising value from all those plastic discs in all those CD racks.

CD Ripping and NAS Drives

Yesterday evening had a late night "get it off your chest" session with a post on the site blog for our CD ripping service, podServe.

Today a more measured tone and some advice. Advice for people who rip CDs and store their music on a network attached unit. I have found most wireless networks will, if they provide a reliable connection at all, will happily deliver streamed music around you house. That's the getting music out side of the equation. Data volumes are relatively low - you get a whole CDs worth of sound out in around 60 minutes.

Ripping CDs is a different proposition and doing that over the same connection is asking a lot. A decent Mac, PC or a laptop will ring at 10, 15, 20 times faster that realtime. A CD gets ripped in around 3 minutes. The data comes off the CD drive, into the computer and is shunted off to the network. A bit of simple maths, you network wireless pipework needs to be around 20 times fatter, sadly it isn't.

So my advice has to be, when ripping CDs to a NAS drive, invest in a bit of ethernet cable and plug that it, at least for the duration of the ripping session.
