[@bobblum5973]

Great job on the troubleshooting, and you showed why it was often better to just leave systems up and running to prevent drive and stepper motors from freezing up. For those who hated the noise in this video: I used to support hundreds of VAX workstations and mini-computers that used MFM ST-series drives. One notorious problem was a hard graphite "button" held onto the end of the spindle shaft, used to bleed off static charges as I recall. After years of continuous use the shafts would wear a dimple into the graphite and cause a very loud high-pitched shriek. Think of chalk on a blackboard but at Mach 2! We finally figured it out and were able to shift the graphite button slightly so the spindle had a fresh spot to work on. On some drives we just removed it completely (not my preferred choice). I hope that helps anyone hitting that same problem!

Thx for the detailed explanation ! Interesting stuff. Happy holidays and all the best for 2021.

Wow what a trip down memory lane. I installed a LOT of these back in the day to clients of my firm. It was so funny, the sales person would interview the client, and ask "would you like a hard disk drive?". Can you even imagine? You could sell 15 of these a month a make a LOT of money. The IBM machines were really over built and bulletproof. Heavy, very heavy.

[@johnc2438]

Mind-boggling. I remember how, almost 40 years ago, my coworkers and I stood up and looked into the hallway of our megacorporation as the IBM PC was trundled down the path to some high-powered' manager's corner office, ensconced in its cabinet and escorted by two security staff. Obviously, the manager was going to perform some computer magic and grow the company with that machine. 10 MB hard drive! I just looked over at one of my external -- run-of-the-mill -- 4 TB drives and did some mental calculations. I'd need a warehouse full of those 10 MB drives to equal the storage capacity of that cigarette package-sized 4 TB drive. I remember when I thought I had all the storage I'd need when I bought my Leading Edge XT-clone computer that came with a whopping 30 MD hard drive.

great video! Wonderful end to DosCember. I got my first PC when I was 8yrs old. It was a SYNTREX 80286 that a neighbor handed me down. It was a 8/16mhz chip and the CMOS had a bad backup battery. I eventually got a new battery for it and then I was up late one night and I saw the advert for my PC on the Home Shopping Network on cable TV! I saw the ad and they said my PC had 1MB of RAM! I was operating with just the 640kb RAM up until this point and only at 8mhz. I went into my BIOS and switched my RAM to allow using the extended memory, added HIMEM.SYS to my startup files and now I had essentially downloaded more RAM. I also set my core clock to a massive 8mhz overclock. So I have lots of nostalgia for DOS machines. It is such a wonderful era and I am thankful that you are helping to preserve it. Happy new year ! Had to edit and add I had a 20MB western digital HDD in this PC.

This reminds me how I saved my western digital hdd (21mb mfm drive). First it had bad tantalum caps which prevented the computer from starting. After replacing them, the hdd was spinning up, then stopping. I was about to throw the towel on it until one time it remained and was readable. So I let it run for a couple of hours that way and then it was starting ok. However soon after it did the same thing again, so I decided to run it even longer. Since then it's been perfectly usable ^^ Sometimes these old drives just need some help to work again :D

[@tux9656]

Very nice restoration! 8 bit ISA slots, MFM hard disk, and low level formats reminds me of my first computer back in my childhood in the mid 90s. That computer I had would have been a decade old then, but I valued and loved tinkering with it just as much as any new machine. I gained such a deep understanding of how PCs work. These days, if you mention a IRQ conflict to most people that work with IT, those people would be totally perplexed as to what an IRQ is.

[@oturgator]

It’s being a stepper motor, not a servo, it may occasionally return to the “calibration” location to eliminate any “cumulative” errors that may occur in consecutive seeking operations.

If bearing are a little dry, but if a leak in motor will have oil over the platters - not good.

[@doublehappiness9889]

I thought that 3-in-1 was not recommended for these type of things, due to containing particles of some sort. Likewise for WD40. OTOH I thought sewing machine oil (which is the same as the type used for hair clippers, I believe) was OK, because it's just pure oil without particles.

My 20MB IBM AT Harddrive (also full height) refused to turn with the original PSU, when I connected a modern one with probably a few more amps on the 12V line it blew a Tantalum cap and after fixing that it finally went into action, took a full minute to get to speed the only thing I ever heard that resembles it is the old air raid siren on the post office. Second spinup was a lot less dramatic, a bit disappointing. :D

A minute in, and hoping you'll restore the case. My 5150 has a few scrapes and a little corrosion on the case, so I'd be keen to see what abrasives and paint you'd use.

[@tw11tube]

The stepper motor going back to track 0 is normal error recovery behaviour. If the system has problems reading or writing a sector, it assumes that maybe the stepper motor got off track by missing a step, and returns it back to track 0 to re-establish the track positions. This is called recalibration, and DOS by default retries operations multiple times with recalibration inbetween, so you always see the motor going back to track 0 several times if a bad sector is encountered.

You might want to look at finding a tool that can optimize the interleave on the drive. I had one of these exact IBM drives with the same controller that I had put in an original Compaq Portable 1, and ran an interleave optimizer on it and it increased the overall throughput 3x. For those not familiar with drive interleaving, it has to do with the speed of the stepper motor. If the stepper is moving to the next sector and it's on the next track, you want that sector to be directly under the head when it moves over. If the interleave is not properly set, the drive could have to make as much as a full rotation before the next sector is there. Slow stepper motors or slower PCs could require a higher interleave ratio. A fast drive with a fast computer can run a 1:1 interleave which means the next track does not need to have the sectors off-set. I think SpinRite can do this, but it's been a long time. Some Norton tools could also possibly do this.
