- I have an application which needs to read mode-2 CD-ROM's. [In fact, they
- are XA disks, but I do not need an 'XA' drive since I will be processing
- all data, including sound, once I have read it from the drive.]
-
- What I would like to know is how many drivers/drives will support mode-2
- operation under MSCDEX ?
-
- You need MSCDEX 2.21 in order to do mode 2. Everyone is in the
- process of updating their drivers for Photo CD which needs the mode 2
- capability. Trantor has one that works fine now for their card and
- chipset (which are used by NEC and MediaVision in their products).
-
- In particular, does anyone know if Adaptec's ASPICD.SYS and the CorelSCSI
- drivers support mode 2 access ?
-
- Also, am I likely to have problems with SCSI CD-ROM drives that wont allow
- the reading of mode-2 data ? As I understand it, you select the blocksize
- you want to read off the drive using a standard SCSI command, and therefore
- all SCSI CD-ROM drives should support mode-2. Or have I got it wrong somewhere
- ?
-
- Not all SCSI CD-ROMs support mode 2, only XA-compatible ones. The old
- NEC drives do not (we have a CDR-73 that doesn't). Most of the
- multimedia-compliant drives have it because it came out at the same
- time as the multimedia spec.
