PWJ55 - Vintage Fujitsu 337MB 8-inch disk

Headcrash….teardown….! That’s an 337MB hard disk from 1987. Fujitsu model M2333. 8 Inch diameter disks and a lot of electronics.
… and some meditation…

Tech data: Disk speed 3600 RPM, avg 20ms access time, 19734 bits per inch, 14kg weight, 2.458MB/s transfer rate
Video Rating: / 5

Using my 13 year old HDD whilst the case is open.

This is for education purposes ONLY!

Taking the cover off your HDD will void warranty and could cause permanent damage.

Don’t worry! After testing, the HDD works fine.

    Thanks for this one… brings back memories of my own teardowns from long ago.
    I used to have the controller boards of one of these hanging on my wall as "art".
    Although… I don't recognise that big, big relay on the power board… I'm sure I would have kept that too.

    Now.. If they could make hard drives and/or solid state drives that last 30+ years once again..

    Of course, using today's technology in a drive of that size would probably yield ~200 TBs.

    Terminator a-cabling is much like the same theory as token ring cabling requiring a termination at the end of a linear sequence.

    Imagine going back in time 30 years and handing the engineers that designed this thing a 256GB micro SD card. "Yeah, it's the size of your fingernail and cost me a hundred bucks. No big deal."

    The most expensive mobile. Great recycling. How much is the disk worth, nowadays, if its work?

    Could you imagine a modern hard disc drive with that many platters and platters of that size? It would have to be about 100 TB..
