Ayone out ther experienced problems with the Mitsumi drive and some CD-ROMS ? I have a LU005 and it cannot run enhanced battle chess. It refuses to even do a driecctory, the drive just "hangs" when accessing the software. I ended up returning the software to the shop where I purchased it and explaining the problem to them (they thought I was pulling a fast one … until they tried it on their Mitsumi).

Peter — Sure, my Mitsumi will not read the Wizardware 6-Pack sampler. Mitsumi knows this, and says that using IRQ 3 solves the problem — well, not here, folks. Funny problem, as CD utilities will do a directory listing, and can identify the drive vol.#, etc — but an attempt to read will cause a hang every time. Sigh. (note that the old Mitsumi did not have this problem). Craig

I could not read two of my disks on my Mitsumi, while they were perfectly readable on other drives. After lots (and I mean LOTS) of checking I found that the problem was mechanical. If the disk is slightly misaligned, the Mitsumis mechanics can't read it. One of the disks was readable for a few minutes while the PC was warming up (after it was switched off for a few hours). Try to have your dealer replace the CD with another CD with the same contents. I would bet that it will be readable then. Boris Schneider, Germany

A while back, I read something in this forum about CD-ROM drives automatically re-aligning themselves after they warmed up. It sounds like this may be happening to you, or may *not* be happening when it needs to. Consequently, replacing the CD-ROM disc may not cure the problem. Can someone else with knowledge about this re-alignment process jump in and perhaps guide Boris on this matter? Best of luck, Boris. Steve Shaffer, MicroDataware

Sorry Steve, I am not the guy with the original problem. I described a similar problem and how I solved it (first: getting new discs. Later: getting mechanically better drive). I appreciate your concern though! So please DONT help me. Help the poor guy who started this thread. Boris

I tried the disc on several different mitsumi drives in the shop where I got the software and no dice, the salesman of the software looked as though he wanted to curl up and die at the thought of a refund.

Uh oh. Which disc is it? I have access to just about everything and will try it on a Mitsumi over here. I need the complete name and if possible the serial code (which is around the hole of the CD etched into the silver before the actual data starts. Most often labels manufacturer and serial number.)

I had real problems with Enhanced Battle Chess (MPC edition).. SO much so that I returned it to a shop and got a copy of "The animals" … This appears OK appart from occasional jerky motion video.

I was instructed by the supplier of my driev to remove any TSR's ….. enmpty machine … no dice. The Animals video pictures are naff on the mitsumi … jerky and losses sound. On the SCSI connected SONY at my work all is OK.

Peter — You really do have some problems — try software polling first, as your computer may not be haoppy with DMA's. How much memory to do have? — How many buffers are you allocating to CD-ROM drivers? Could you list out your config.sys and autoexec.bat files? — the drive should NOT be working as you describe.

I have a 486 (50 MHz), DMA & IRQ appear OK, I have disconnected my sound board and still got problems. Maybe the mItsumi is incompatible with my machine … Then again lots of other discs work OK.

Peter — Did you try software polling? If not, please do so as that will "fix" IRQ conflict problems. Craig

Greg, I will change my PC to software polling as soon as I get time … currently I am on an introduction to Unix course at my work (though God knows why). Thanks for the info. Peter Wilkin
