If you have an old but still working hard drive

I have a pretty old drive in my PC which is only used for backups of backups - if it dies, no harm done.

I figure that it's done around 4 billion revolutions by now. People who leave their rigs on 24/7 probably have drives that would dwarf that number. By any standard, that's major-league reliability for a mechanical device.
 
I have an old 6.4gb drive in my Linux box that dates back to 1999 (or somewhere close to then). It is only used for F@H.
It replaced an even older 2.1gb that is still in working condition.
 
5400rpm x 60 min/hr x 24 hr/day x 365 day/yr x 7 years at 24/7 operation = ~19.8 billion revolutions.
 
i have desktop computers in the lab that have been on (except for thunderstorms) for 5+ years, those old drives are mostly 5400 rpm

5400 x 60 x 24 x 365 x 5 = 14,191,200,000

there might be a 7200 rpm drive in one of them, they'd be what, 33% more?
some of them are from 2000, so the most i might have would be around
26,490,240,000

Impressive! What make is the drive? Is it SCSI?
 
My old employers have a 386(!!!) based PC that runs their voicemail system. It was installed around '94. It's still running to this day on the same 540 meg HD. That thing has been chugging along for over 13 years.

:Q
 
7200 RPM * 3.5 years = 13,136,256,000 revolutions. Or somewhere close to that.

Yes, it ran almost 24/7 for the entire time.
 
2.5GB 10K IBM SCSI HDD I got it in 2000 used. I ran it for 6 years non stop So 31 Billion revolutions while I owned it. My roommate that I got it from had it for at least 2 years in his system, and it was at his work for at least 2 years before that. So I would put a rough gestimate that the drive had about 45~46 Billion revs before I retired it.
 
A drive that's accessed continuously 24/7 is under much more stress than an just a spinning platter.
 
Our retail store is running software on a system using a 486DX2 66MHz chip with 20 MB RAM and a 320 MB Western Digital HDD bought in 1993. That drive ran only intermitently for 4½ years, but since early 1998 has been on 24/7. No problems evident so far, but I'm planning to change machines just in case.
 
I have an 80mb conner drive.
Weighs about 5 pounds and is slooooow.
No idea what rpm it is though.
And yes its still works
