I've looked into this. The snag is that powering from a 12V SLA is not a particularly good idea as you can't guarantee the voltage. The solution is to use two giving you an input voltage of 24V and one of the PicoPSU family that allows you to use 12-24V input. SLA is a pretty good battery choice fo...

IIRC UDF doesn't deal with sparing itself -that is performed by the drive (there was a discussion on the UDF refelector about using UDF on flash a while back). I think it does some clever things with the bitmap. I wouldn't like to swear to any of the above, because a) it was a while ago b) I wasn't ...

Averages
Am I the only person who gets really annoyed when someone asks for an "average" usually wanting an arithmetic mean? (this brought to mind today by one of the questions in the IQ test) I mean I usually want someone to calculate the range of different aircraft, but when I want that I don't ask them to...

Orifice 2007 has been requested alongside Vista by a customer, on a new PC they want us to build for them. I dont have any problem with Vista, but the customer is only after Word and Excel, but they are not a Student or Teacher, so they are going to have to spend the extra £30 for the "Basic" vers...

I was reading that Word-07 is in a different file format? If you send that to someone with Office-2003, will they be able to open it? And vice versa? There is a new format, but it is incredibly easy to tame it to using the old one (a distinct lack of nag screens telling you that the new one is so m...

I understand that carbon composites are actually pretty good at blocking RF frequencies. However, Ultra aren't selling this as a system, so won't have had to pass all (any?) of the RF tests (the same reason why it took a long time before you could buy windowed prebuilt systems from a manufacturer -a...

I think we need to be very careful in attempting to extrapolate the results of the 300W model to the 400W one -in all the pictures I have seen the 400W Zen has an exposed heatsink, which makes it likely that this is a quite different electrical design, as the heatsinks in the 300W model beneath the ...

[Romeo]: "It is also worth noting that the 2.5" Seagates seem quite capable of letting you know if you are giving it an innapropriate power supply -although the behaviour does not seem to be documented anywhere." How does a Seagate laptor drive react? My 12GN only sits there silently, with enclosur...

My experience is that Seagate USB drives (both the 2.5 and 3.5" variants) spin down -although whether this is due to windows spin down times, or something in the drives I don't know -I've never tested it. The Seagate 2.5" USB drives power from almost all standard compliant USB ports, the maximum cur...

Unless I'm much mistaken, most current DVD drives are only capable of ATA-33 (or whatever it's actually called) whereas the HD will be capable of ATA-100. Quite possibly what the error message actually means is that a HD is running on ATA-33 (which would typically be caused by use of a 40 conductor ...

What I really don't get is Seagates choice of components -either they expect to sell less than say 10,000 of these or ??? I can't actually think of any other reason right now. An x86 is a crap choice for a product like that, the only reason for using it would seem to be that you can buy that board o...

Or a carbon nanotube heatsink! Very good conductor. The problem with carbon nanotubes is it is a one dimensional conductor. All the chemical bonds are in one direction.
