Q: Replacing CD-ROM on 6300CD

I have an old Performa 6300CD that the cd drive croaked on. I picked up a new one off ebay, this one is an Apple CR-507-C 12x drive. It is SCSI 50 pin just like the old one. I can't get this thing to work at all. I transferred the adapter from the old drive onto the new one, and set the parity, 0, and 1 just like the old drive. The old one had a jumper option for add/remove media, which the new one does not. The new one has a jumper option for term power, and since this is the only drive on the channel, I have that jumpered. Any other ideas? Thanks.

Performa 6300CD, Mac OS 8.6 or Earlier, OS 7.5

    The jumpers that you've listed are correctly placed, including the one for TERM PWR. I'm surprised that the original CD-ROM drive had the "add/remove media" jumper, because all of the Matshita SCSI CD-ROM drives that I've pulled/installed do not have it. Is it a Sony drive and does it have the Apple logo on the label? As for the 12x Matshita drive that you installed, if you felt it snap-lock into place, the blade-like adapters on the back should be plugged into the connector strip correctly. Did you notice whether the pins on the adapters appeared darkened in color? Those adapters, like plug-in motherboards, can develop connection problems caused by oxidization on the pins or in the slot that they engage. Did the original drive have a specific hardware failure or did it stop being recognized? If the latter, I'd be inclined to think that the problem isn't with the drive, but with the motherboard's connection. I'd suggest removing the motherboard and gently cleaning the gold-plated pins on the upper and lower sides of the edge connector strip with a soft gum eraser, to restore a bright finish. If you have a can of (aerosol) zero-residue electronics cleaner, you could also try spraying the slot. Re-install the board and see if the CD-ROM drive is recognized.

    The old drive is a Sony with an Apple logo. It stopped reading media, but was still recognized. There doesn't appear to be anything wrong with the connectors on the adapter, they all look gold and shiny. I guess one thing I don't know is what two of these jumper positions on the back of the new drive are. They are between the SCSI id jumpers and the term pwr jumper. They just have a dot above each of them, but no text. Are these important? The new drive receives power and will open and close, but is not seen by OS 7.5.1. Is there any reconfig I need to do besides reset PRAM (already did that) and make sure that the CD-ROM extension is being loaded on startup?

    If certain pairs of pins are only designated with a dot, they may be for manufacturer use or not used at all. Your problem may be driver-related, which should be easier to troubleshoot. In addition to the Apple CD-ROM extension, you should also have the following drivers installed in the Extensions Folder: (1) Apple Photo Access, (2) Audio CD Access, (3) Foreign File Access, (4) High Sierra File Access, and (5) ISO 9660 File Access. Because CD-ROM drives were slower when OS 7.5.x was developed, I'd recommend downloading/installing the newer "Apple CD-ROM" (version 5.4) extension, which was designed for support of faster (12x - at the time) drives. Ignore the reference to the PowerBook, because this driver can be used on all desktop Macs running the specified OS software. Double-click the downloaded .img file and it will mount on the desktop. Drag the mounted image file to the hard drive icon. Open the "Apple CD-ROM 5.4" folder on the hard drive and drag the extension to the Extensions folder. Because the "Apple CD-ROM" file is in use, you may not be able to drag the newer version to the Extensions folder to replace it. If that's the case, drag the existing "Apple CD-ROM" file to the trash (but don't attempt to empty it), then drag version 5.4 to the Extensions folder.

    I am having a difficult time getting this to work. The img.bin file that I downloaded has to be moved to the mac via floppy since it doesn't have a network connection. I only have access to a PC with a floppy drive and a network connection, so I have to transfer the file the mac via pc exchange. Once it is on the mac, it only sees it as a pc exchange file instead of an img. Any ideas?

    I hope that you do not mind the intervention.

    When transferring a file downloaded on a PC, keep it encoded (in this case MacBinary = .bin) until on a Mac. That is, do not try to decode or alter the file in any way on the PC. The .bin file name may become truncated, but this can be disregarded.

    Once on the Mac, use StuffIt Expander to decode the .bin (do not double-click; instead, drag the file onto the StuffIt Expander program icon). The result will be a disk image (.img). In order to mount this very image, Disk Copy (6.3.3 here) must be installed on the Mac.

    Please post back if a suitable version of StuffIt Expander is not available for the 6300CD.

    OK. Try this: On a PC with a floppy drive, download the MACDISK.EXE file here. Prepare an empty 1.44 MB diskette via the FORMAT A: command in DOS or the Full formatting option under Windows (this is important). You may have to temporarily switch off any anti-virus software. Launch the MACDISK.EXE program on the PC. Follow the on-screen directions. When finished, immediately eject the floppy. The disk is now automatically Mac-formatted, and ready for use in a Macintosh computer. This disk contains a StuffIt Expander 4.0.1 installer.

    That all works, and I almost have this working. I am running into one small problem using disk copy. It is the problem outlined in this article.

    http://docs.info.apple.com/article.html?artnum=60371

    I am doing the following:

    Moving the disk copy.bin to my desktop. Dragging that bin onto Stuffit expander to expand the compressed file. Then, I double click on the disk copy.sit and it says "verifying disk copy". Finally, there is a disk copy program on my desktop, which I then copy into my hard disk and try to run. I get the message shown in the article, but I think I am following those steps correctly.

    edit: nevermind, I figured it out. I had an old image mounted on my desktop.
