What a hell is this?! Multiread CD-ROM!

Multi-Read is the latest CD drive format. It is supported with the CD software you are using. Have you recently done an update to either/both your operating system or CD Software. That is where it came from.

The older version of the Adaptec software supported doing this with the RW, the newer supports the latest standard (read new hardware sales). I still get the functionality of the older one, but the mancine I use is a Windows NT 4.0 with a 2X burner.

If you need the other functionality, try using an older unit with non updated Windows & software.

If a CD-ROM isn't multi-read compatible, then a CDRW will not work in it.

Adaptec has software called Direct CD that you can install that will allow you to read the CDRW in any computer.

As far as why it worked before:

If you can see only data recorded in the irst session on the CD but not in subsequent sessions, it may be that: You recorded the CD in CD-ROM (Mode 1) format, while your multisession CD-ROM drive only recognizes CD-ROM XA (Mode 2) multisession CDs or, your CD-ROM drive does not support multisession at all.

If you can see only data recorded in the last session, you may have forgotten to link your new data with data previously recorded on the CD. Make sure to select a track in the Load Contents tab before recording.

multiread is a term used to describe a recordable cd that was created using more than one session. let's say you burn a blank cd with 20 files on it. when you start this initial seesion you have the option of 'closing' the cd or leaving it 'open'. if you close the cd then the table of contents is flagged such that the cd can never be written to again, even though it may not be full. however, if you leave it open (the default for easy cd creator), you then have the option to come back later and add more files, or even replace existing files on the cd. let's say you initiate a second write session adding 5 more files to the 20 that have already been burned onto the cd. you now have a multi-session, or 'multiread' cd. the existing table of contents on the cd is nullified and a new one added to the cd that show the current state of 25 files on the cd. this new table of contents is apparently a different and newer standard than the first and cannot be read by older cd drives - sometimes incorrectly, sometimes

oops! here's the rest...

sometimes not at all! if you want to ensure that a cd burn can be read by older cd drives, then create them using only one session. if you need to, copy the cd contents back to your hard drive and then re-burn the cd on another blank cd.

there are a miriad of issues involved in being confident about burning a good cd.
the mechanical laser burning process in conjunction with the substrate material used in manufacturing recordable cd's is not an exact science. there are many stories out there where this name brand recordable cd will not work reliably with that name brand cd writer. these issues center mostly around the 2 major types of substrates commonly used (one is known by its blue-green color and the other by its gold color) and the various on-off laser timing theories held by the cd writer manufacturers. this is also why cd burning can only be done at the tortoise speed of 4x.

other issues are 'open' and 'closed' cd's, buffer underrun, etc.

there is a good deal o

CD-ROMs, CD-Rs, and CD-RWs use different wavelength LASERs in reading and writing disks. A multi-read CD-ROM is one that is capable of reading any type of CD disk, including the CD-R and CD-RW types. This extends to CD players and DVD players usedfor playing CD music. The ones that aren't Multi-Read capable cannot play a CR-R copy of a CD, but a Multi-Read can play copied disks.

jeez! won't hold much...

there is a good deal of study (and some experimenting) required to be confident about burning a good cd. there are plenty of articles on the internet and your favorite search engine will easily dig them out for you.

doyour homework and good luck!

OK, multiread is used to read Multi Session format CDs. For example, some software can burn a cd multiple times (max 99 session). Each time you burn your CD, a session is created. And the data string is completed with one lead-in and one lead-out oneach session. Due to this issue, some old CD-ROM drive can only read single session, for multiread, after the 1st session is read, it will try to search for next session if available where the old CD-ROM drive just stop after the 1st session is read.
