Not seeing full capacity of CD-RW discs

    I'm having a strange problem....when I format a CD-RW, it only has like 537MB available. I've tried different media, and same result. CD-R's seem to see full capacity, however. System specs:
    WinXP Pro
    TDK VeloCD 52X internal

    Any ideas?

    Since you are "formatting" a CD-RW, I assume you are using packet writing software (DirectCD, InCD, etc.) to use the disc like a big floppy.

    The 537MB you are getting is normal for packet writing on a 650MB disc. The extra space is needed for the file structure, to enable random writing/deleting anywhere on the disc. There is no way to get any more space with packet writing. A 700MB CD-RW will give you about 572MB of usable space, and a DVD-RW will give you about 4.37GB

    If you want to get the full 650/700MB of space on a CD-RW, you have to write the disc as you would a CD-R, but then you give up random write/delete access and you have to rewrite the whole disc to change anything.

    Wow....didn't know the overhead was so high for packet writing. Thanks for the info.
