I still have the very first CD-R I ever burned. Used a 1x or 2x speed SCSI Sony burner and the disc used the dark green dye. It was even readable in an old 1x Mitsumi drive, the one where the whole mechanism slides out with the clamshell lid. Crazy thing is that original 1x Mitsumi drive was not supposed to be able to read any CD-R, no matter what. Still readable even after 17 years. The nearly invisible blue dye is nowhere near as reliable as the original dark green or dark blue dyes. It does have one error in one Windows 95 CAB file. Dunno what the problem was with that one file but whenever I'd build a PC I'd always have to burn two copies of Windows to the disc to go with the system because every time that same CAB file would develop an error in one copy, though both were read from the same source files. The extra crazy thing is both copies would verify 100% against the source then the one file would suddenly develop a read error - and it wasn't just with one burner. I've only had one CD-R go to pieces on me. It had a crack at the hub which extended just into the TOC zone. I tried using Unstoppable Copier to recover the data. It wasn't having any luck, the drive would spin up and down over and over then suddenly it revved up to max speed and BANG! Plastic confetti. I was looking at it so I saw the front of the tray pop out. Shut it down, took the drive out and apart. Shook out the debris, popped the front back on the tray and no problems with the drive. Something quite annoying about recordable optical discs is stores either will not stock dual layer DVDs or if they do they only have extremely overpriced 3 or 5 packs in jewel cases or at most 25 disc cake boxes. Staples only stocks 25 disc cake boxes of Maxell DVD+R DL - the absolute worst brand of DL media made. Out of six or more burners I have only ONE will work with them. HP 2.5x speed DL media was also rather horrid. Drive compatibility was decent but I had almost a 50% write failure rate. When it comes to rewriteable DVDs, most drives support up to 8x RW discs but just try and find any DVD-RW faster than 4x. And where are the Blu-Ray drives, burners and media? I've never seen any BR drives of any kind at Staples and for only a short time did they have any discs. Dual layer DVD, 8x DVD-RW and BD-R/RE are all turning out to be like the 2.88M floppy disc. Stores that sell computer supplies and parts should have had shelves full of all these for the past decade but have either failed to stock any at all or only made tiny token efforts at selling them. The old "We don't have that because it doesn't sell well." BS! You can't sell what you refuse to put on the shelf! If Wal-Mart would order a billion *good quality* dual layer DVD blanks and make sure all their stores had 50 and 100 disc spindles of them, the media would sell very well - and Staples, Office Max and the rest would have to stock them too. --- This email is free from viruses and malware because avast!
