HFS Format (not HFS+)

Hello,

First of all, you would need a computer with a SCSI interface. For a PC, this would mean a separate SCSI card/controller.

In order to read from or write to HFS (Mac OS Standard) hard disks on a Windows PC, you may have to look for appropriate (in some cases older) versions of utilities like TransMac, MacDrive, and MacDisk. There can be limitations depending on the Windows version. Earlier, there was also an HFVExplorer utility.

In fact, the easiest way may be to just look for another early Mac with an internal SCSI connector (such as an LC II or III) and a monitor. Remove the existing SCSI hard drive (if any) and install your drive(s). Boot the old Mac from a suitable floppy (for example, a Network Access Disk 7.5).

Disks formatted as HFS+ (Mac OS Extended) require at least Mac OS 8.1, and can thus not be used with System 7 Macs.

Pretty much anything with a SCSI controller can access and can overwrite a SCSI hard disk drive storage device.

To get to a 50-pin SCSI bus connection, you’ll either need an old SCSI controller or an adapter from what SCSI you have to 50-pin.

Which also means you get to enjoy the full glory of getting a SCSI bus to work, too.

The cost of the adapter may well exceed any revenue from the sale of the storage, though.

DBAN or a bootable Linux distro would be typical option, and there are other choices (EFF).
