13.2 MB for anyone interested like I was.

And I thought my 70mb full height 5,25" hard drive was big...

This is older then any standards we have seen in a PC. So getting it up and running would probalby require a lot of work and building a custom controller card that can handle everything.

Nice find!

I'd suggest asking this same question over at the Vintage Computer Forum (http://www.vcfed.org/forum/forum.php) as well, since they tend to be interested in really ancient non-PC stuff like this.

Mine is bigger, 3 time at least! 55Kg, 10Mb

This guy I knew who had a used computer resell store in a small warehouse use to buy used computers from corporate auctions.
Liquidators and bankruptcy’s and just out of business companies.

Once he had a BIG hard drive like this one but I think it might have been BIGGER.

He asked me if I wanted it for FREE. But I turn him down. I would have like to have it today.
The thing weighed allot and he had to move it around with a fork lift.

They have 2 of the things for sale. I want to RAID0 that.

🤣.....That would be a smash hit on youtube.

Is the transparent plastic normal or is this some sort of demonstration model?

AFAIK transparent plastic was used commercially only in Western Digital Raptor X. Everything else before and after that are demonstration models or for internal use/testing only (to check mechanics in controlled environment). "IBM Fault Definition Label" strongly implies latter.

Interesting stuff, but I doubt it's functional at logical level, i.e. write/read.

The model appears to be 62EH and it was used by the System/34

The smallest S/34 had 48K of RAM and an 8.6 MB hard drive. The largest configured S/34 could support 256K of RAM and 256MB of disk space. This cost over US$200,000 back in the early 1980s. S/34 hard drives contained a feature called "the extra cylinder," so that bad spots on the drive were detected and dynamically mapped out to good spots on the extra cylinder... so technically while the system did not recognize more than 256MB, slightly more space than this existed.

The computer I'm using now has 48 GB of RAM. I don't really need it, but thought it would be funny to have a million (1024x1024)* times more memory than the ZX Spectrum.

* Does this constant have a name? Mebillion? Mellion?

That's pretty cool. The one place I worked at had one of those floor standing drives where you could swap out the platter assemblies. It was in some storage room and one of the guys that had been there for a long time showed it to me.

(Has Chrome lost the ability to select character encodings? Firefox still allows you to display pages in Windows-1252/ISO-8859-1 but I don't see the option in Chrome)

*IBM called them hard files back then.

What would it take to get this old IBM hard-drive to work ?

Divine intervention.

I was expecting to see one of those 5.25in 'full height' harddrives (basically as large as Bigfoots, but much thicker and heavier), but this simply looks awesome!
