    Partitioning didn't exist for very early DOS, so some controllers allowed you to take your 32MB hard drive and make it appear as two 16MB drives.

    A similar thing was done with Apple II early hard drives--make a hard disk look like a pile of floppies.

    Wasn't something like this available for IBM PC as well? I mean there was some external HDD for 5150 in the DOS 1.xx era.

    I have several Amstrad 2086s, those are 8086s XT class machines with a 30mb RLL hard disk.

    Perhaps, but by 1.26, there was a limited amount (FAT12) of hard disk support available. No subdirectories, through.

    The Taiwanese turbo XT clone my family bought toward the end of the '80s had a 40 MB Miniscribe in it. So certainly it wasn't unheard of. But I do recall many of the ads I spent all kinds of time memorizing were mostly for 20 or 30 MB systems, even for a while after. The Leading Edge Model D2 (10 MHz 80286) we upgraded to around 1990 had only a 30 MB drive (which we replaced with the 40 MB drive from the XT clone). My vague recollection is 1989 or 1990 was around the time I started regularly seeing 40 MB drives as a base option.

    This item may have operated like this as it was for multiple different platforms. I'm sure I read somewhere of a Winchester for the PC that worked like a stack of floppies. I guess it would have been good for compatibility.

    My 1988 (or maybe 1989) Vendex HeadStart LX came with a 40MB MiniScribe factory installed too, controller is mainboard integrated (makes it rather specific for using a 8450XT, tried a Seagate ST-3040A/X to no avail since it only sees 20MB with that disk).

    But I was the first in my class with 40MB disk in their XT and 3.5" HD floppy drive (and 4-color CGA for that matter) LOL

    The ST-506 is a 5 MB MFM drive.
    If you're looking for DS/DD or DS/HD 3" or 5" floppy disks, PM me. I've got some new, used, and factory over-labeled disks for sale.

    Yes, but the term "ST-506" (or "ST-412") is also used for the interface introduced with these drives.
