If I ever get famous I shall use my position to publicise what will become known as Underwood's Second Law of Computing - never start a quick job on a Friday afternoon.
Client rings up, he wants some music put onto his iPod from the backup DVDs we supplied when we ripped his CD collection last summer. As he's off on holiday he wants it done quickly, and his PC has broken. Can we help? Yes, this is one for our great standby program XPlay 3 which enables you to move digital music files onto (or off) an iPod without using iTunes. "Great" says client (who lives in Chelsea) "I'm on the A12, about 10 minutes away, can you do it while I wait?"
Of course, we did, and client went away to his cottage in Suffolk very happy. But afterwards I couldn't use either of the DVD drives on the PC. They were there in the System properties boxes but with a yellow warning triangle next to them. Looking into properties it said something about Code 39, a driver being out of date. I fiddled and fiddled, by which time it was 18:00 and I had to be somewhere else. But it nagged at me all weekend, I put in an hour on Saturday and a couple of hours on Sunday, but no joy.
Today, Monday, I just had to get the DVD Reader / Writers back so I sat down to crack the problem. Which I eventually did. I won't bore you with how but I will tell you why it went wrong.
Connecting an iPod to a computer incurs the risk that it will be grabbed by iTunes and automatically synchronised. Client's iPod should be linked to his PC, even though that's broken. So I didn't want to run the risk that all his music would be lost, specially as he was sitting in my kitchen reading The Times. So to be absolutely safe and sure I deleted iTunes from that PC.
Now I find that a consequence of deleting iTunes in Vista (plus a few other programs according to Microsoft's website) is that the uninstall program deletes key values in Registry. It is Registry that lets your operating system know what is attached, so the computer thought the DVD devices were corrupted.
The fix was achieved by running a downloadable fix from Microsoft, equally it would probably have been fixed when I re-install iTunes for the project that begins tomorrow. So there you have it - if you lose your ROM drives, if you get the yellow triangle and driver error code 39, you know what to do - but most of all, if you plan to attempt a quick computer job, don't do it on Friday afternoon.
