Hmm, I have disks dating back to 1990 and none of them has ever lost data or caused read errors. But some posters said that they still can have lost writeability. No idea why. I did always make sure to never buy disks from dubious sources but always the good stuff, name brands. > And unlike hard disks, diskette R/W heads actually touch the recording > surface and gradually wear away the media. > Yes, and that wear is clearly visible. However, the typical disk is used as file storage and only once in a while read back, and then only small parts of it. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.

There's stuff out there that dates back to the days of 8" floppies. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.

Lots of companies feel they don't have time to waste testing for compatibility with Win 7, or finding drivers for it, or re-training staff, or handling the support. It's better with the devil they know. Besides, Win 7 has no advantages over XP if you are actually /using/ the computer, rather than admiring the pretty clock on the desktop. > Vista & Win7/Server 2008 either release have methods to read in > RAID/HBA drivers off flash or USB devices during installation while > booted into WinPE.

I had to install windows (XP and Win 7) on a couple of computers recently - it is often faster to install Windows from scratch than to start using a typical "pre-installed" system (after it takes ages to install windows from a hidden partition, you then have to waste more time removing all traces of the "demo" and time-limited junk that comes with system). While Win 7 installation is mildly improved over XP, it's still seriously inefficient. And once you have the basic system installed, you then have to find and install the drivers - which are often totally absurd (I had to download a 100 MB file for an Ethernet driver, including it's useless utilities - and it wouldn't even install until I'd added dotnet runtimes!). The Windows developers really should get hold of a few Linux distributions to see how OS installers /should/ be made - they have a decade or so catching up to do.

Doesnt explain the claim that they can be read fine and the problem is with new writes. > And unlike hard disks, diskette R/W heads actually touch the recording > surface and gradually wear away the media.
