Mike Richter, were you born with "Scam Artist" emblazoned on your face? -------------------------------------- Mike Richter (Friggin ****) splattered (7/31/04): jason wrote: I burn CDRW disks using the Adaptec DirectCD program that came with my computer. All of a sudden, the disk I use for backup is thrashing around and freezing my system. I can't access the disk at all It means that the TOC can no longer be read - the disc is essentially dead. This is discussed in the usual references, the CD-R FAQ and the primer at my WWW site. Briefly: The theoretical life of an erasable is rarely approached in practice. Each time a changed fixed-length packet disc is removed from the drive, the TOC is written. (Does CD-R FAQ say that? Why drag CD-R FAQ into the poppycock?) Is it now TOC, not directory, that's supposed to be written? Is anything written when a fixed-length packet disc is removed? ========================================== Mike Richter is a LIAR (directcd/eject)(i) ========================================== ============================== From: DeepOne Subject: CD-RW Disc broken on DirectCD Date: 7/9/00 Mike Richter (Lying Scum) spewed (7/3/00): When you load a fixed-length packet disc, the directory information is read from the disc and translated in RAM. When you write to the disc, the data are recorded immediately but the directory is updated only in RAM. When you eject the disc or shut down Windows properly, the directory information is transformed and written back to the disc. Therefore, from the time you change something in the (RAM) directory until that writeback, you can lose the directory if you have a failure. That failure can be a power transient or a system lockup or even forcing the disc to eject (in spite of the lock) using hardware. I don't believe this is true with the latest versions of DirectCD (I'm using 2.5d with Win98SE). I've watched the disc write lights on my Plextor drives when ejecting a DirectCD CD-RW disc, and the drive never does any writing at that time. Once, in an attempt to prove this, I wrote a bunch of files to a DirectCD CD-RW disc. As soon as the write pulses ceased, I pressed the computer's RESET button. After the computer restarted, the CD-RW disc was fine, and all the files I had just written were fully accessible. ============================== ---------------------------- Mikey, you are a Lying Scum! ---------------------------- -------------------------------------- Mike Richter, were you born with "Scam Artist" emblazoned on your face? -------------------------------------- |
