The WDAC1210s and the WDAC2850 I have seek-test with no computer (with nothing jumpered, meaning "Master only"), and if they're jumpered to "MA" (Master with slave present), they will not seek-test until the slave detection is done. They were probably busy looking for slave. Good demo of what put WD on the map! They sure atoned for the Tandon-based stuff they had to ship before the WDAC140/280.

you parked the drive right?

I had ST3243A in 1994. That was the absolute SLOWEST drive I ever owned. You are not imagining things; these are way slower than they should be. My WDAC1210 that was my other hard drive trounced this in terms of speed. I also had ST3390A later in 1994. Very good drive. It's apparently got some CDC design on it (that actuator solenoid sure sounds like some of the other CDC-designed Seagates)

This video felt like a funeral montage. R.I.P Kalok!

Have to say I enjoy the random rock music that goes with this! I also enjoy the sound of old hard drives 😄

Have you tried adjusting the head stack's addressable range?

I believe this drive uses a pancake servo rather than a stepper.

Who is really the last stepper hdd? This Seagate, or Kalok octagon kl3100?

chug chug chug chug

It just wanted to be a steam train.

The Maxtor just arrived today, but there are several layers of strange. This drive was very, very poorly packed, only having a couple of plastic air packs on top of it. No protection at all on the bottom. And second of all, I got the wrong model. I was supposed to get a Maxtor 90651u2. but I ended up getting a Maxtor 91021U2. The thing is, I've only seen this drive mentioned once on the internet that I know of. So I have decided to keep the drive. The seek-test is also a bit odd. It has the usual Maxtor startup that the Maxtor drives typically have from that period. But then 2 seconds after you think it is done, it does a BUZZZZZZZZZZZ. But it works and is healthy as of right now. And that brings us to now. I wanted to ask you since you have a ton of drives and you've been collecting them a while so I was wondering if know anything else about the drive model I got, please let me know.

I just bought a new drive for my collection. It is a Maxtor 90651U2. I found it for $15. It is one of the drives i've found on eBay for the cheapest. (My quantum fireball was $5 more) I am waiting for it to get here. I hope it works. So look for an updated hard drive collection video soon, with a better mic (aside from my 40mb drive which I dont have access to at the moment.) And I am not going to be getting any western digital drives (the only way I am getting them is if they are in a lot with quantum or maxtor drives) Anyway I need to get sleep cuz tmrw is gonna be a busy day.

I recently got an ST-1144A. Really unique drives. Also really odd. They tend to throw temper tantrums and randomly toss the heads around if the molex connector is slightly loose, which is very common. The connectors on those are very tight and aren't built to be unplugged and plugged in a lot as it seems. That's a very sad downside, because these are otherwise very reliable drives. Mine has 0 bad or slow sectors, even if its a little finicky.

I think two of my drives are failing. The older of the 2 seagate U5's and the JTS Champion I decided to livestream me messing with my hard drives for 3 hours on my second channel @pdguy5000 with installing old operating systems on my drives. The 2 hour one is better than the 1 hour one. Anyway in the first stream my Seagate U5 beeped several times and then spun up, just to spin down. And then it happened again when I tried to boot it back up. SO I gave it one last try and after it did some more spindle start beeps, it finally stayed going. My guess it stiction. I have been using a usb adapter. It powers the drive externally and with the usb itself as well. (Molex Adapter). Anyway in stream 2 (the 2 hour one) Where the Quantum and Connor didn't give me any issues. The same can't be said for the jts where reading data seemed to be fine, but writing data would stop working about halfway through and the entire drive would go unresponsive until I restarted it. So yeah. I just need help figuring out the issues with this drive. I should also mention that my other U5 works flawlessly with the usb.

I was going back through and watching your 40MB hard drive video and I got an idea. In the past on one of the comments, I remember you saying something about having several Seagate ST351A/X drives. And that got me to thinking, would the date of manufacturing have something to do with the speed of the drive. Also it would be nice to hear more than one stepper motor drive again running windows 95. It would prolly sound like a late 80s early 90s computer lab!

Oi

I enjoy the sounds of old Caviars! ❤

Loads of useful info in this video - thank you! I'm in the process of testing / recording all my HDDs and I'll put this to good use :)

Great video! I appreciate the time and effort it must have taken to make this comparison 👍

I recently acquired a caviar 140. amazing drives

did you ever low level format the drive?

I have such a disk! I will know what to prescribe in the Bios. The computer sees it, but there are no partitions.

Speedsys could have killed it. The intense movements of the heads could have been a bit to much for the drive and shifted some of the poorly/cheaply made parts out of place or caused some damage. I am not that good at inspecting hard drives though. Just a thought.

Could be a mechanical problem with the stepper motor.

Dang, no WD93044A huh These early Caviar drives are nice though

Long time no see, my old friend. miss the times we spent hours together (because you were kind of slow). Memory is eternal!

Stepper needs oil I can assure you. Either that or the metal strap is stretched/damaged. You could also oil the HDA pivot.

Before and after I think your stepper needs some oil...

The high pitched squeal is a possible issue, since it "holds" when you stop there once in a while I think it is a failing or failed stepper motor controller. This disk uses microstepping and half stepping to achieve it's displacement, which means the stepper controller will "hold" the head position when on a microstep. This is done with high speed PWM in the software and as such you're probably hearing a shorted transistor dumping a bunch of current through a stepper winding.

hey there. just like older quantums, this drive might have that sticky rubber bumper issue. check if there's rubber and if you can, replace it.

wow, look a that thing shake when it reads and writes! I love stepper motor drives!

I found a JTS Palladium on ebay for $7.50 should I get it? Also I found a Kalok 343 for $49.99 should I get it too?

I grew up on WD Caviar HDDs during the 1990s, so some of these brings me back

Can you do a hard disk collection video?

Seems like your stepper is dropping steps. They do that if the load is more than they can move when trying to step fast. Probably dried up old grease in the stepper. Perhaps try getting a few drops of penetrating oil into it?

Weird, your caviar 1210 doesn't seem to do the seektest. I'm curious if yours has the same weird behavior as my caviar 31000 where it has a delayed seek when set to the master jumper setting. My caviar 31000 only does the normal seek when in cable select or slave. Does your caviar 1210 seek normally when set to slave? Edit: i assume that delay is normal, as multiple of your drives have it, and so does my caviar 31000.

how much WD caviar 2200 ?

bad capacitors

These drives make a really pleasing sound when hurled forcefully into a dumpster.

Beeeeeep Beeeep!

Wooow. My Childhood WD Caviar HDD spinning up Sounds😍😍😍Very Amazin Black Version WD Caviar HDD.😍Please more more such video.

Ok, you forgot 1170 there in the description and thumbnail

We get that mfm like stepper motor action with a modern interface, I want one

Sounds great!

This video is saddening in a way, I didn't notice any fans. ;(

I assumed Kyocera drives were only MFM, I guess I was wrong. Interesting how the curve changes in speedsys when it gets close to the end of the drive. When you stated that story about the drive I thought you managed to buy the exact drive you sold years ago but I guess this is better since it looks to be in very good condition. I have seen that video you mentioned about the Lapine drive before, which was quite interesting (Interestingly, lapine is a French word for female rabbit though it’s likely just a coincidence)

I have one too, and yes, very slow ^^ Sounds of the stepper motor reminds me plastic straw lol

Sadly, I haven't found the easter egg, or I may have and not thought much of it. Or is the "Duckson Plays: You're welcome :)" at 9:49? That is an extremely cool sounding drive. The video is also fantastic, and I like the commentary and editing. It is nice to know we both like extremely slow hard drives.

First video on internet about this HDD wow!
