Q When I try to defragment my Windows XP computer, a message appears saying: “Please run Chkdsk/f”. What does this mean and what should I do? GC, via e-mail

A The computer is telling you there are some broken files on your hard disk that need fixing. While this may indicate a serious deterioration of your hard disk, it may also be the result of a minor glitch.

Unless you know how to use Windows system tools, I suggest you take it to a repair shop and ask it to fix the files, and then give the disk a quick once-over.

Alternatively, download the free hard-disk diagnosis software HDD Health from www.panterasoft.com and see what it uncovers.

Q I am planning a trip abroad and want to use an online storage service to back up my photos. Can you suggest any sites? GC, via e-mail

A Take a look at StoreGate (www.storegate.co.uk ), which offers 2GB of storage for free or larger capacities from £3.49 a month.

The software needed is no more complex than a tiny browser plug-in, making it ideal for use via internet cafes or a friend’s computer. However, be aware that large photos can take a long time to upload, especially from a tiny web cafe in the back of beyond.

Q Is it okay to switch off the power supply to my computer system when it is not in use? MG, via e-mail

A It’s a sound idea to switch off all your IT appliances when they’re not needed, to avoid wasting electricity on standby current. The only reason to leave a computer on is if it does regular nighttime backups of your data to an online service, but even then you should tell the software to switch off the PC once it has finished.

I also suggest you consider a Standby Buster (£15 from tinyurl.com/59wvsd ), a remote-control off-switch; or an Intellipanel (£22 from tinyurl.com/5t88p3) - a multi-plug adaptor that deactivates all the kit attached to it once the PC is shut down.

Q How can I make copies of our son’s wedding video for distribution? I have Windows XP Home Edition. PR from north Wales

A The hard way is to connect your video playback device (camcorder, VHS machine or DVD player) to your PC and use a video capture program such as Pinnacle Studio (www.pinnaclesys.com ) to download the video so you can edit and burn DVDs with the footage. The easy way is to go to www.snappysnaps.co.uk , find your local branch and ask for its prices on video duplicating and transfer services. I vote easy, unless you fancy a bit of work.
