I had occasion to re-burn some old discs a while ago, several were from the era of single speed CDRs, and I foolishly put them in a drive that can read at 52x. Second disc in literally exploded. Very loudly. I thought it was the PSU caps so leapt up and yanked the power lead. When I dismantled the drive it was full of metallic confetti and SMALL shards of polycarbonate, none bigger than a thumbnail. It totally banjaxed the drive, I was quite surprised at the amount of energy in a small spinning disc. The fragments left deep gouges in the CD tray. Luckily I had a later backup which I made sure to read at 2x. Now I mainly use a stack of obsolete HDDs and copy from one to the other every few years. I use a fair few 35GB Rev discs too, and give sets to family to stash. Hard copy is the only sure way, preferably chiselled 6" into a granite cliff face... ------------------------------------------------------------------------------ Meet PCI DSS 3.0 Compliance Requirements with EventLog Analyzer Achieve PCI DSS 3.0 Compliant Status with Out-of-the-box PCI DSS Reports Are you Audit-Ready for PCI DSS 3.0 Compliance?
