Having trouble using a CD-ROM on a different...

As with audio CDs, discussed in the previous section, there are several possibilities. The media compatibility issues mentioned above apply to CD-ROM as well.
If you're using CD-RW media rather than CD-R media, you have to be sure that the CD-ROM drive in question is MultiRead compliant. Some older drives are able to read CD-RW media, but most are not. Newer drives should work fine.
If the disc was written using a packet writing application like DirectCD (where you format a disc and then copy files directly to it, instead of creating a disc layout and recording a whole bunch of stuff all at once), some CD-ROM drives will stumble on packet boundaries. Refer to section (4-21) for information and a possible workaround.
If a packet-written disc was closed in ISO-9660 Level 3 format, it won't be usable on systems that don't support ISO-9660 level 3 (e.g. DOS). If the disc was *not* closed as ISO-9660, and is still in UDF, you will need a UDF driver; see sections (6-3) and (6-3-1) for an overview and pointers to free drivers
