Macintosh SE/30: Old HD-20 and New Macintosh SE/30< Back to Tech Info Library Index
This article last reviewed: 31 October 1990
What must one do to access a (non-SCSI) HD20 disk drive attached to the disk drive port on the new Macintosh SE/30? I tried placing the old "HD20" file in the System Folder, but it didn't work.
Using the criteria of "Macintosh SE/30 AND NON-SCSI" search AppleLink's Technical Info library for the article "Macintosh SE/30: Doesn't Work with an Apple Hard Disk 20." The following is more information on this subject:
The (non-SCSI) Hard Disk 20 does not work with the Macintosh SE/30. The Macintosh SE/30 has the same logic board and ROM as the Macintosh IIx, which does not support the Hard Disk 20. Therefore, the code to support the drive is not included in the ROM of the Macintosh SE/30.
There are ways of retrieving the data from a Hard Disk 20 for use on the Macintosh SE/30. First, using a Macintosh Plus or Macintosh SE, transfer the data to another hard disk that the Macintosh SE/30 can read. The necessary equipment and steps to do this are:
To transfer data from a Hard Disk 20 to the internal drive, these items are required:
Once you have the necessary items, follow these steps:
Additionally, we have included an INIT Utility that reads the data from the Hard Disk 20 and puts it on the internal hard disk of the Macintosh SE/30. As with all INITs, place it in the System Folder of the startup disk. The Hard Disk 20 will now be visible when you start up with the Hard Disk 20 turned on.
Warning: Do not try to write to the Hard Disk 20. Trying this can result in the loss or corruption of data on the Hard Disk 20.
When the Hard Disk 20 icon is visible, you can drag the files from the Hard Disk 20 onto the internal hard disk of your Macintosh SE/30.
The code for the INIT Utility is not supported by Engineering, and no changes will be made to it. Be very careful when using this Utility and do not distribute it. Once you have copied the Hard Disk 20 to your Macintosh SE/30, be sure to remove this Utility from your System Folder.
