| Using Zip drive as HDD for Macintosh Plus |

It should look like this Unfortunately, that's a parallel port Zip drive. It looks like it has a SCSI port, but it's not really. OP (@Jon146) posted this question over two years ago! If you read the rest of page 1, they identified they had a Parallel port unit and got the issue resolved. |

Oh man, thanks guys! Any idea why the driver isn't loading? If you format the Zip drive with the oldest Zip Tools the a driver gets written on the disk and the OS extension is not needed for the disk to mount. Then you just copy your OS files to the disk. I've done it all the way up to 8.6. |

4.2 is the needed version. |

One of the tricky bits to watch out for is if you're booting a Plus from a Zip disk with version 4.2 of the boot driver on it, but then stick that disk into your G3 (or whatever) which has a later version of the driver loaded, it will automatically over-write the 4.2 driver on the disk with whatever driver it is using, rendering the disk unbootable on the Plus until you reinstall the 4.2 driver on the disk. The disks have a driver written in the boot area on the disks which is separate from the extension driver that gets loaded. Iomega apparently assumed you would always want the latest version of the driver on your disks.
Just FYI |

oh, that's a nasty wrinkle. Didn't know that. |

oh, that's a nasty wrinkle. Didn't know that. Yes, one of those things that make it so you can’t just go about putting it in just any drive! |

4.2 is the needed version. I have discovered that IomegaTools 4.2 (not the driver 4.2) REQUIRES system 7 AND a Mac SE or newer to run (it needs the 256K ROMs or newer the plus uses 128K ROMs) so you have to use an alternate drivers loaded with HDT, silver linings, etc to make a zip bootable on a mac plus if you dont have another mac that can use iomega tools 4.2 |

That will put it in the wrong partition, a freshly formatted zip disk has 4 partitions (Viewable with silver linings), 3 small hidden ones, the third holding the embedded driver that is used when booting from a zip disk. The last partition is the majority of the disk and is the mountable HFS partition. |
