Impressive machining

[Bulldog9]

I'm on day five and have been catching up on some small projects around my place.

Today I decided to try and fix a couple of my external hard drives that have been wonky lately. After unsuccessfully being able to recover one I decided to disassemble it and here's what I found.





Overall I'm pretty impressed by the finest and tolerances of the machining. It's amazing to me that they can Mass produce and assemble these devices with such precision.

This particular external hard drive was my backup for the last 10 years it was a 2 TB and the drive would no longer index properly.

Now I have three new shiny coasters :-)

That is an interesting approach.

OTOH, being more of an Neanderthal, I used an axe on one and a cordless drill on some others, both methods admittedly limiting repurposing options such as yours.   

I could think of no Guzzi applications, but I was, however, able to get some significant air time on drilled-out ones when used as a frisbee.

Cool parts.

In the lower left corner are two brackets that carry magnets.  These are SERIOUSLY STRONG magnets.  The magnets are just glued to the brackets.  Put the bracket in a vise and bend it.  The curvature will usually snap the glue and give  you a powerful magnetic tool for various uses around the shop.

so.... after disassembly... were you able to retrieve the data on the hard drive?

sometimes it's a bitch to read that tiny font.....

Already done my friend I slid a razor knife blade between the magnet and steel body and popped them off.

Was very surprised at how strong these magnets were.

BTW, Bulldog9, how's your excellent 912 P-car doing these days? Sorry, thread hijack

I was fortunate enough to work on some of the early computers like PDP11, the first one monitoring a water works you would initiate by switching a bank of switches to make it semi smart then feed in several reels of punch tape, no monitor of course all it did as far as I can remember was light up a bunch of digital digital water level displays. A later one used for measuring the precious metal content in a mining slurry had 8" floppy drives, I don't think it had a hard drive but it did have a monochrome monitor the measuring part operated using a radioactive source with a detector at liquid Nitrogen temperature -320F
My Brother worked for Hewlet Packhard, one day he bought home a desktop machine with a 4" cathode ray monitor, I remember it because at the time it was worth the same as a house in Auckland.
The advances in computer technology are mind blowing as is the machining, all for a few dollars.

My first computer at my last job had a drive that lasted the twenty years I was there. It had been demoted to playing internet music but that one drive spun nearly continuously for the whole time. Never attempted to calculate how many trillions of revolutions it turned over those years.

40+ years ago I had a 5 1/4" 10 MB hard drive fail and after replacing it made this clock out of the old one.  I still have a couple of the platters out of it laying in a desk drawer in my old office.  Here is a picture of how it came out.
