Hi, Sorry if these are really basic/stupid questions, but please bear with me as I'm a novice when it comes to burning CDs. I have a CD Re-writer drive - the info on it is: IDE-CD R/RW 4x4x24 Write Speed : 4x600kb/sec Read Speed : 24x3600 kb/sec Firmware Rev: 1.08 Address : 1:1:0 I don't burn many CDs, but when I have in the past (using Roxio DirecCD) everything was working fine until I recently bought some new blank CD-RW discs (Packard Bell CD-RW 12x Speed 700mb capacity). Now, on the CD Info page, it says . I tried putting a previously burnt CD-RW disc which says 4x guaranteed 650mb/74 mins and it read it ok. When I tried to re-format it, instead of taking the usual 50 odd minutes, it took over [bold]8 hours![/bold] although it eventually worked and I could drag files from my C: drive onto the CD. So here are my questions: 1. Why are the 12x speed CDs incompatible? I asked when I bought the discs whether they would work with my drive and was told that they would write at 4x speed - it just means that, depending on the drive, it can write up to 12x speed if you have the capability. Is that true? Would it work if I bought CD-RW 4x discs? 2. Why did it suddenly take more than 8 hours to format a disc it had successfully previously burnt? Does that mean there’s something wrong with the hardware? Any help/explanation would be greatly appreciated. Thanks in anticipation.
