Not for long. And there is no way that it doesn’t have issues. Also that old of hardware will have connections that modern pc don’t have support for. So basically either the drive will die or the hardware running the drive will. But op is specifically talking about drives that are unplugged, just sitting around. All drives will lose data from being unplugged, and it has been known for a very long time. However they are incorrect on the “no storage drive” can last long. Tape drives are the go to for long term storage. Something like 15-30 year lifespans and 50+ on other types of tape drives.
Person 2: it is, and I have experienced it myself.
Person 3: “yeah but here is a list of reasons I just made up why your experience doesn’t matter”
The first comment was not saying “after long enough time certain drives do this/hardware degrades/won’t run in modern machines”, they were blanket stating “no storage lasts beyond 2-3 years”
I was trying to explain that the volatility of a 20+ year old hdd and hardware is very high. If there is important data to you, you may want to get it to a device that is not so volatile. Also it’s not like I made any of this up, I have a decade of it experience including plenty of data recovery. It’s how I know that the “no storage lasts beyond 2-3 years” statement is blatantly false.
I don’t touch the drive for years on end and it works. The connections are IDE and Molex. I have an IDE to USB data cable and a Molex power cable. I can plug it into my PC that I just built a few months ago no problem.
The data on “old” style disk drives is physically etched upon the disk magnetically. That’s why the data still exists, despite sitting unused for long periods of time.
Neither you nor the OP know much about this topic.
I’ve worked it for over a decade at this point, I know exactly what I’m talking about. Sure the drive works now, but it is mechanical and mechanical things WILL fail. Obviously adapters will allow it to interface with modern hardware.
I don’t know if you understand how magnetic drives work. They are not permanent magnets, that means that they will lose their charge unless you maintain the drive. It’s not a matter of if but when. And maintaining the drive means it’s plugged in and spinning, which wears the drive down.
I bet if you ran a smart report on that drive, it will have plenty of “old age” and “pre-failure” on many different attributes. If there is data important to you, then it should not be on that drive.
The data is stored as magnetic charges on the physical disk. They are not permanent magnets. They lose their charge and thus the data, slowly over time, while not being plugged in. A plugged in drive gets electricity to maintain the charge on the disk. How it does it specifically is based on the firmware of the drive. Idk why you can’t just google it yourself and probably find a better and more specific explanation.

I mostly figured that’s what you thought, and it’s completely wrong. They are permanent magnets. As permanent as any ultra-tiny magnet can be.
Hard drive platters are made of glass or aluminum, and have a thin layer of a metal alloy in which to store a magnetic charge. There is no electricity flowing through the platters of a hard drive, ever. They are 100% passive.
I didn’t google it because I can’t google, “tell me what false belief this person has.”
I never said the platters were electrically charged. The electricity powers the drive which has firmware. That firmware controls the magnetic charges and can correct errors, depending on firmware, hardware, and such. Also you are incorrect. The platters are not permanent magnets. The permanent magnets are a part of the spindle motor. I guess it also depends on how you define permanent magnets. The magnetic material most commonly used, for platters, is cobalt. Where as the “permanent magnets” (for the motor and typically when referring to permanent magnets) are neodymium. Maybe try a search that will actually result you in answers. I had no problems doing so when you challenged my knowledge.
You’re the one making extraordinary claims. You need to back them up. You said the data in HDDs only lasts 2-3 years unless they are plugged in. That is patently false in both ways. No, they don’t, and no, keeping them plugged in doesn’t help what data loss does occur. Error correction occurs when reading the data. And data is only read when asked for.
The firmware doesn’t “control” the charges. They just sit there. When the drive is powered but not in use, it sits there. Nothing is being done to “maintain” the charges.
If you don’t consider a static magnetic charge on a platter to be “permanent”, then no magnet is permanent. The only impermanent magnet is an electromagnet.
I did not say that. I said you will lose bits over years. When typical hdd’s are in the terabytes that means there are trillions of bits. A few bits here and there can be corrected. A plugged in drive will lose data differently than an unplugged drive. A plugged in drive won’t be as likely to lose data from the magnetic charge becoming too weak to read properly.
Oh sorry the firmware controls the parts of the drive that interact with the magnetic charge. The firmware has the ability to look at the health of the drive and take action on it. Though it does depend on the drive and its capabilities.
No magnet is truly permanent. But if the platter were using more “permanent magnetic material” then it would require a lot more energy to switch the state or flip the bit. It’s why they use a very small amount of magnetic material in the platter.
You are glossing over details that make you seem uninformed or lazy.
Also, this is not a feature in hard drive firmware. A scrub like you are describing is a feature in filesystems or raid solutions. A disk on it’s own will not rewrite data over itself. Show me a product page from a disk manufacturer that says it does. If you can find it, it will not have been a popular drive because of the increased power usage and reduced life of the drive.

Explain how a hard disk loses data from being unplugged. More importantly, explain how it retains data specifically while being plugged in.
