I have a question that I am hoping someone on this list can help me find an answer to ... I apologize in advance if this question is inappropriate for this forum ... I am involved with the development of a hardware driver which interfaces to several ATA/ATAPI devices (i.e. HDD's, CDROM's, compact flash, etc...) My problem is determining the correct sector size for CDROM's when performing DMA. In the case of PIO, this is not a problem since the device tells me how many bytes to expect. The platform (it's custom) I am working on requires support for both data CD's (ISO9660 - 2048 byte sectors) and audio CD's (Redbook - 2352 byte sectors) ... I realize that this is an issue of the media present in the device but what is the preferred method of determining sector size? Thanks for any help you can give me, /mbs --- Mark Sawyer Sawyer Software Solutions, LLC 2 Lincoln Drive, Bow, NH 03304-3209 Tel: 603-228-9214 / Cell: 603-496-3509 / FAX: 603-228-4810 --- AOL's AIM: FirmwareWizard _________________________________________________________ Do You Yahoo!?
