Basically, yes they are rewriteable. ..but... the more often they are used the more they degrade, usually this is seen as a decrease in the "available space" on the disk (cough). The technology used on rewriteables is now about 8+ years old and is not improving. Why? Because the "new" solid memory chip technology: 1) offers approx 20x capacity per production buck. 2) does not (sorry JC) suffer from age degredation as much as hdd and CD/DVD technology ( in short, its currently better to start moving your kids pictures onto Ipod tech because it will last longer than CD - and by that I mean that the CD dyes are starting to degrade now. (!) ) So much for promises! 3) when the hdd manufacturers have finished dumping their capital investment on the market and move to the solid state manufacturing line they are now building under licence from Intel, then (hohoho) you will start to see some "amazing" advertising from them (the current hdd manufacturers) about the BRAND NEW TEKNOKOLOGY THAT YOU (repeat) YOU, MUST HAVE (BUY) BECAUSE .... ... ... given the current capital investment in hdd manufacturing process, I'd say about 3 years, but I may be wrong... :-) It's always a good idea to keep a sly eye on the Intel research and devel website. Usually, they tend to be 2-3 years ahead of the market and, for some strange reason they usually co-incide with a "moore doom" prediction from one Mr Moore ... hmmmm? .... meanwhile .... erstwhile ... Yes, Vista sucks. Yes, Office 2007 sucks Having now run an entire dev site entirely M$ free for coming up to 3 years: 1) No, Virginia there is no Linux based Access97-de-Claus, but ... 2) PostgreSQL is the best kept secret on the planet 3) Yes, MySQL sucks 4) Yes, MS-SQL aint all its cracked (sic) up to be 5) Yes, motherboard embedded RAID is about as good an idea as Intel onboard sound chips. 6) Linux is ... H A R D .. to learn. Or perhaps that's "Windows is hard to unlearn"? 7) .NET is a huge executable overhead. No, no, .NET is an unsurmountable execution time overhead..... mono ... not yet awhile, abigwhile 8) ASP, hahahahahahaha, IE2 hohohohohoho 9) PHP is about as secure as Windows 10) DAO actually worked, ADO doesn't 11) Yes, you can run ODBC within Linux, ... but you do need to find the drivers.. 12) Yes, JC, There is a linux distro that "just works" check out PCLinuxOS 13) and I do mean 13) Software firewalls are about as much use as a chocolate teapot. on the 14th day of Christmas my true love sent to me ... an end to oligolopies .... ymmv best wishes for a great yule and a safe season of festivities. regards bruce
