Doh.. I hate having to reply to my own post, but I searched for this ages ago, so I wrote the previous post. Now, after posting I find what I was looking for.. typical.
If anyone else is interested in this, a very good source of info is here:
List of media types and apparent sizes on CDMediaWorld: http://www.cdmediaworld.com/hardware/cdrom/cd_cdr_ info.shtml. I don't know how easy it is to identify the exact type of disc you have though.. I only managed to find the ones I have by looking at the capacities listed from what I've observed myself.
Having played with things a bit and tried using Easy CD Creator to tell me the disc size, I've found that the TDK 74 minute / 650MB CDs I have can actually store 658.7MB, and I can store 702.8MB on the 700MB CDs.
Dunno why but I always seem to buy TDK products.:> Audio tapes to VHS cassettes to CD-Rs. Never had a problem with any of them, so that's probably the reason why.
The TDK-Europe website wouldn't come up, but www.tdk.com (TDK US) did. Can't seem to find any manufacturing facts on that website though.
CD-ROM drives have been known to fail in such a way that the laser stays on while the motor does not. After a few days, maybe a week of that, the plastic on the CDR starts to bubble.
A simple workaround of the problem is to not keep a CD in your CD-ROM drive if it's not being used;> Though backing up your valuable CDs is a good plan too.
Yea, I got a spool of 50 12 speed TDK 700MB discs for $10 from Staples a while ago, with the rebate (and yes, it came in the mail for those rebate nay-sayers out there).
One question: How much can you fit on a 650MB or 700MB CD-R?.. don't just be a smartass and say 'duh, 650 or 700MB'.. I know you can get more on there.;>
Is there a place that collates information gathered on this stuff, so people can check brands and REAL capacities so they know that they can cram on more data to a CD if they need to? If not, I think I'm going to start to do so, so please.. let me know of your maximum capacity CD-R burns!
So far I've only tried TDK 700MB and 650MB discs and I've only written a few CD-Rs, with 701MB and 652MB as the capacities I've had on the discs without problems, not exactly 'pushing the envelope', so I'm interested to learn of other people's findings.
Fascinating read.. correct link is here too btw (one above had a space in it, that I didn't notice immediately).
It certainly is a reminder of the holes in the world's defense systems. Once you think you've handled a particular threat, another one you never even thought of comes to be your biggest problem.
Eh?.. $1.6 USD to a UKP.. so that'd be about $16 billion.. (with a b).
And of course if that was a UK 'billion' is in a million million, and the US 'billion' is a thousand million, then you'll end up with $16,000 billion (USD).. which seems like an awful lot.
Sounds like a good idea to me! I'd like to be able to do that myself:)
I'm still trying to get my LUG off the ground for my area, which is south-west Indiana. If there's anyone in that vicinity (or even if you're not THAT close!) who would like a LUG to join, please look into tinyLUG:)
It's not the government we need to fight, it's these companies
I don't know why but I'm remembering the preface to the game Frontier - Elite 2. There was a 'timeline' at the start of the game manual that talked about events that happened in the past of the game, but were obviously in future years.
One of the entries was, chillingly I think:
'First ever war between a government and a corporation 20xx' (I forget the year)
How long before corporations start becoming like 'countries' themselves and will arm themselves to protect their 'rights'. A somewhat scary thought.
Still, I hope it never comes to that.
I hope from what we saw of Rep. Boucher the other day that people with influence in the government can overturn this before it goes too far.
Ah yes, the good old bootblock viruses.. I even remember a bootblock virus detector/cleaner too. I grew up on Amigas, amusingly enough to most I assume. Bootblocks were great for lots of things. I forget how big they were.. first 512 bytes of the disk?
It does *seem* like a long time ago that it was all floppy disks and I didn't even own a hard drive.. Ah well, times change... rapidly. I'm nearly 25 and I feel like an old sage when thinking about doing things with computers 10 years ago.
This works best if you open the case backwards (without breaking the copy protection seal), so it can be claimed you didn't open it. Plus, it would have the bonus of making the "unplayable" CD's truly unplayable.
Uh..
How can you say it doesn't work in a CD player unless you've (noticably) opened it to try it?
Only then, when we can sway the fence-riders, will we make a stand.
I think that's what he's trying to do by asking for people willing to write to their member of congress. Seems like he's got the right idea, and supporting that is a good thing to do.
Given the high level of clue he displayed in his other answers, I would like to hear his informed opinion on this one.
Yes, it really is refreshing to see someone who is part of the government actually having a brain and using it well. Also good too that when he didn't feel confidently informed to answer, he didn't just guess at it. If only more people (government or otherwise) would think like that.
I hope everyone is taking note of answer #6:
I would encourage anyone interested in assisting our effort to send their electronic mail address to jody.olson@mail.house.gov
The LEON model also exists in a fault-tolerant version, capable of detecting and correcting single-event upset (SEU) errors in any register or RAM element.
I wonder.. would that make the processor less susceptable to crashes from other things apart from a cosmic ray 'twiddling' a bit at random?
Like in Windows for example, if the OS or a program screws up a register or does something else stupid, do you think this chip could correct that error by itself instead of crashing?
Be amusing that.. Open source hardware to 'fix' bugs in Windows. We all know the ultimate 'service pack' for Windows is a Linux distro.
LOL.. 'rock solid stable' for any Windows OS is a whole different meaning than 'rock solid stable' for a Unix OS. 'stable' for Windows is what most people still consider 'flakey' when compared to a Unix machine.
