Dr. Damien's Development - Hard Drive Crashes

Somewhere in my repository of technical artifacts, I have an 8in double-sided floppy that I used on a Xerox computer.


I think it held 256K of data (128 on each side)


I agree that backups are extremely important.  I recently dropped a new 1TB drive while moving it.  It was running at the time.  Not 100% sure that there is damage, but I didn't take a chance.  It's been backed-up on yet another drive.  I will use this one for transient data..  For hobbies, of course..

When I was a grad student, we had a 10MByte hard drive connected to our embedded PDP-11/23.  It failed once a year, so we would never trust data on it, except as a transient storage mechanism.  Permanent storage was on 8" floppies; they were more reliable!


That must have been an RL-02 or similar. Smiley Happy


Within arms reach on my desk there is a stachk of artifacts I keep around as viual aides for the "younuns". From bottom to top it is.

An 8" floppy (double sided woo-hoo!)

A punch card

A core memory array with a wopping 512 bits (yes bits not bytes).


When i was studying to maintain disk drives I learned about types of storage ordered from short term to long term storage.

Petroglyphs last even longer.

Pterodactyls also last longer, but holding them down so you can write on them can be tricky...

I love these search engines , .... it's so old that I think it's worth reposting it: 


Sing this song (author unfortunately unknown) to the tune of Yesterday, The Beatles:


All those backups seemed a waste of pay.
Now my database has gone away.
Oh I believe in yesterday.

There's not half the files there used to be,
And there's a milestone
hanging over me
The system crashed so suddenly.

I pushed something wrong
What it was I could not say.

Now all my data's gone
and I long for yesterday-ay-ay-ay.

The need for back-ups seemed so far away.
I knew my data was all here to stay,
Now I believe in yesterday.
