I suggest to use Windows Disk Management next time. Explorer only shows a drive is there's a compatible partition on the drive. This one being from a video recorder, there's a good chance it had Linux partition it which Windows won't handle. But it will show up in the Disk Management as unknown partition, where it can be deleted and a new, compatible partition created.

It is called a voice coil motor because the earliest drives used a linear motor and the coil and magnet assembly looked exactly like a speaker assembly.

@12voltvids 29 күн бұрын

Actually it's still a linear motor mounted on a pivot

Whichever it is, they were certainly capable of "voice" after a fashion. Some of the older drives used to beep error codes through their actuators and motors. It seemed to be most prevalent on IBM's larger SCSI drives around late 80s and the first half of the 90s, though as they're generally reliable you'd rarely ever hear it, unless you messed up the cabling, jumper positions or bus termination. Of course we're talking far enough back that there were still a handful of serviceable parts on them, whereas now it's usually cheaper to just bin a defective drive and replace it. That is to say rather than needing specific error codes, today the diagnostic merely consists of "Ah. It's not working." and little else.

@@12voltvids Not really, there is a cosine error associated with the head only being perpendicular to the tracks in one position. The main reason we switched (I used to design them) is that only two bearings are required, a linear actuator requires six, so cost. The other reason is the linear actuators requires more space, and we were trying to get them small.

@davidnorton573 28 күн бұрын

@@HighTreason610 We didn't do that, with an interface like SCSI you just send the error codes back to the controller. We did make the beeping noise you talk about however. In the early days drives didn't use ramp loading, the heads were always in contact with the disk. We are talking about small drives here, not the ones with the removable packs. Sometimes they would get stuck, so if we detected an overcurrent on spin start we would stop trying to spin (avoid destroying the head suspension) and send a tone out to the actuator in an attempt to float the head and break it free allowing it to be spun up.

Amazing technology in the small hard drives. There is about a 5mm gap between the heads and the platter surface.

How is that when the platters are only separated by 3mm?

Screws in HDDs are para-magnetic, they're stainless steel. These are slightly magnetic, that's why the strong magnet attracts them but the screw driver can't.

I have a couple of external hard drives and I don’t have a problem with it. So I decided to backup the files onto discs like CD-R’s, DVD-R’s, DVD+R’s, BD-R’s and M Disc for archival use, or you can use Flash Drives or SD cards to move files on there to save some space.

Toshiba 2.5” HD are one of the more reliable of the mechanical HDs. I’ve rarely lost one, even with physical damage. Hitachi 5400 rpm once were one of the worst with head failures (ironically the 7200 Hitachi ones were pretty good). Seagate still to this day has a weakness to the brand with still common dead sectors on all models. When sliding the head over the platter, make sure the disk is rotating to minimize surface damage. When someone slams their hands on the laptop, the platter and heads can become jammed and the motor doesn’t have enough torque to overcome the friction, but you can walk and rotate the head to home to save the data. When running with it open, you can blow the dust off lightly before spinning up, once spinning the dust doesn’t really settle, but dust will cause bad sectors but it’s usually not that big of a deal for data recovery. The bearings can bind up too from dried up grease. Heat can help in loosen up the grease temporarily. Also… I believe you can microwave the glass platters like a CD for a cool effect.

Why are glass platters used in 2.5" HDDs, and metal platters used in 3.5" HDDs? I've always wondered. Although in older 2.5" HDDs, like ones from the '90s, the platters are metal, I think.

Hey 12 volt! I really hope you see this as im in desperate need of some help regarding the technique RS-M63; my pinch roller is not engaging and im not sure if its because the mechanism is bad or the roller itself, I bought a replacement but im not sure how to begin taking the mechanism apart to determine what the fix will be. Think you could help somehow??

The M63 is a purely mechanical deck. I did a service on one a few years ago. Video is on my channel.

HAHAHAHAAH Deja Vu. I had a stack of Platters from the Bigger drives about 24" inches high before it fell over .. You have a need for about a 100Lbs of magnet ?? Even after the Magnet was separated from it's base. I had them stuck all over every square Inch of my work Cubicle. I did not realize the little ones were Glass till I went to bend one. It didn't explode like Your did. Luckily I was not cut .

Laptop drives are glass, desktop drives are usually aluminum cored. At least this is my understanding. Higher density desktop drives might also be glass these days.

You can’t put platters in another drive. They have to be perfectly aligned to each other. You also need the eprom to tell the heads where the data is. All it sees is gibberish.

@mrnmrn1 28 күн бұрын

@@RectifiedMetals YOU can't put the platters in another drive, but data recovery specialists can. There are specialised software tools which will upload a custom firmware to the drive to read and save the raw data from each platter separately than merge them together. Yes, the alignment data from the original controller board I think is necessary for this to work, but there might be a workaround even for that, just a lot harder. There're tons of data recovery videos here in which they swap platters between drives. Some of their software tools are like black magic.

@eDoc2020 24 күн бұрын

@@RectifiedMetals There's an easy trick to maintaining alignment: put a piece of tape on the outside of the platter stack. AFAIK on more modern drives most of the configuration data is stored on one of the platters, the program on the board is only used for some initial functions. Of course there are other problems with swapping platters, it's definitely not worth doing to get a "free" drive.
