Hello I have an old Barracuda 7200.12 500GB HDD, I want to use it as an external disk. I thought about buying a USB-SATA adapter, on the Allegro I found something like this: and such: http: //allegro.pl/adapter-usb-na-sata-ata-ide-2-5-3-5-led-zasilacz-i6189932472.html And here the question...

The second, in the first no 12v power supply

This is the partial truth. In the first one there is no 12V, so the drive will not move - 12V is used to power the engine. I consider the second suggestion to be an exaggeration. Seriously, do you want to buy the entire power supply with the controller to boot the hard drive? In my experience, the electronics of the 2.5 inch USB pocket can handle this task, but not each . The cheapest are basically the same first link for you. The more expensive ones already have a controller and a 5V to 12V converter inside, but they don't have enough current capacity to drive a 3.5-inch drive. The better ones give advice and everything works, but powered with USB 3.0. When powered from 2.0 it is required to power from two USB ports at the same time (sometimes after booting the disk goes to disconnect the plug that only powers the disk and it happens that the disk is still working). Currently, I cannot recommend a specific model, but I will ask a friend about the pocket model that I bought and which can do this and that. Regards.

So 12V in a 3.5´´ drive is used for power supply, and 5V for what? For data transfer?

To power electronics (integrated circuits etc.), and probably to power the head drive but I'm not 100% sure. You also have 3.3V in the drive's power plug. It is not used for anything.

such a kit costs around PLN 25, I doubt that it would be more expensive than the disk pocket

Because it's not. It will work, but you will have another device near the TV, another power supply and you need another power outlet. There are also disk pockets in the form of a console-sized box. You also power it from the mains. The usual pocket for me is a plus that requires only usb, and is much smaller. Unfortunately, but, as you can imagine, a 3.5 disk for a 2.5 enclosure will not fit, so either it will lie without the enclosure, or you will make your own

There are ready enclosures for 3.5-inch drives with an external power supply in the form of a plug.

My friend, The main idea of using external drives is that you can easily unplug them and move them to another computer. You have a nice disk, so I would suggest USB 3.0 Such a more decent pocket will cost you a hundred, o, for example on the allegro: 7060818038 By the way, was the ban on sending links to the auction lifted?

This one is great. The usual 2.5 would be cheaper but without housing, but everyone has their own priorities. Not because the expiring links make the topic useless in the future. You can already do the auction number

I don't recommend this adapter which you put in the second link. I bought something like that in Saturn and after the first connection the power supply burned. Fortunately, the disk did not suffer. A better option will be the pocket that ORMO_PL has sent.

Hello
I have an old Barracuda 7200.12 500GB HDD, I want to use it as an external disk. I thought about buying a USB-SATA adapter, on the Allegro I found something like this: http://allegro.pl/przejsciowka-adapter-usb-3-0-do-sata-dysk-hdd-ssd-i6748031418.html and such: http: //allegro.pl/adapter-usb-na-sata-ata-ide-2-5-3-5-led-zasilacz-i6189932472.html
And here the question arises, this 1 is intended only for HDDs but 2.5 "while mine has 3.5". The number of pins is the same for both variants (7 + 15), but the question of power supply arises here. On my 3.5 "disk it says that the power supply is 5V and 12V while the 2.5" disk has only 5V power supply, is this adapter as in 1 link enough and I will power the hard disk via usb or it must be the one with 2 link with a separate power supply ? What does 5 and 12V power supply mean for a 2.5 "drive, can it be powered by 5V or 12V, or that 12V is intended for connecting the power supply and 5V for the SATA data plug?

My friend,

The main idea of using external drives is that you can easily unplug them and move them to another computer.
You have a nice disk, so I would suggest USB 3.0

Such a more decent pocket will cost you a hundred,

o, for example on the allegro: 7060818038

By the way, was the ban on sending links to the auction lifted?

Topic summary

✨ The discussion revolves around using a Barracuda 7200.12 500GB HDD as an external disk via USB-SATA adapters. Users highlight the necessity of a 12V power supply for 3.5-inch drives, as the 5V provided by some adapters is insufficient for powering the drive's motor. The first suggested adapter lacks a 12V supply, making it unsuitable for the Barracuda HDD. The second adapter, which includes a separate power supply, is recommended for reliable operation. Users also mention the availability of enclosures specifically designed for 3.5-inch drives that come with external power supplies. Concerns about the practicality of using multiple power sources and the size of the enclosures are discussed, with a preference for compact solutions that utilize USB power.
Generated by the language model.

FAQ

TL;DR: 3.5-inch HDDs need 12V for the motor and 5V for electronics; "12V is used to power the engine." Choose a 3.5" USB 3.0 enclosure with its own power. [Elektroda, Anonymous, post #16884524]

Why it matters: This FAQ helps anyone repurposing a 3.5-inch Barracuda 7200.12 avoid underpowered USB adapters, data loss, and failed power bricks.

Can I use a 2.5-inch USB–SATA adapter to run a 3.5-inch Barracuda 7200.12?

No. 2.5-inch-only USB–SATA adapters lack 12V output. Your 3.5-inch drive will not spin up without 12V. Use an adapter or enclosure that supplies 12V. [Elektroda, marqqv, post #16884406]

Why won’t my 3.5-inch drive start without 12V?

The spindle motor needs 12V to start and run. Without 12V, the drive won’t move at all. As one expert put it, “12V is used to power the engine.” [Elektroda, Anonymous, post #16884524]

What does the 5V line on a 3.5-inch HDD do?

5V powers the drive’s onboard electronics, including controller ICs. Some designs also use it for actuator control. The forum notes 5V is for the electronics. [Elektroda, Anonymous, post #16884609]

Is the 3.3V pin on the SATA power connector used here?

Not generally. The thread states the 3.3V pin is present but unused on these drives and setups. [Elektroda, Anonymous, post #16884609]

Will USB 2.0 power a 3.5-inch HDD if I use two ports?

It’s unreliable. Some users report needing two USB 2.0 ports just to power certain setups, and disconnections can occur after spin-up. Use a mains-powered enclosure. [Elektroda, Anonymous, post #16884524]

What’s safer: a bare USB–SATA adapter or a full 3.5-inch enclosure?

A quality 3.5-inch USB 3.0 enclosure with its own power is the safer, cleaner choice. One recommended option was described as “great.” [Elektroda, Anonymous, post #16885107]

How much should I budget for a reliable 3.5-inch USB 3.0 enclosure?

Plan around 100 PLN for a decent, reliable enclosure that supports USB 3.0 performance and includes proper power. [Elektroda, ORMO_PL, post #16885096]

Do some 2.5-inch enclosures step 5V up to 12V for 3.5-inch drives?

Some have internal 5V→12V converters, but many lack the current capacity for 3.5-inch motors. Results vary and instability is common. [Elektroda, Anonymous, post #16884524]

Are cheap all-in-one USB–SATA/IDE kits safe for 3.5-inch drives?

Be cautious. A user reported the bundled PSU burned on first use, though the disk survived. Reliability varies widely with these kits. [Elektroda, djtommy, post #16885146]

Can I run a 3.5-inch drive without any enclosure?

You can, but you’ll add clutter and need another wall outlet. It also offers no physical protection. A proper enclosure is cleaner. [Elektroda, Anonymous, post #16885085]

How do I set up my 3.5-inch HDD as an external drive?

Buy a 3.5-inch USB 3.0 enclosure that includes an external power adapter.
Insert the drive, secure it, and connect SATA power/data inside.
Plug the enclosure into mains and USB, then format if needed. [Elektroda, Plumpi, post #16885094]

Should I choose USB 3.0 or USB 2.0 for this drive?

Choose USB 3.0. It improves throughput and is recommended for easier portability and performance with 3.5-inch drives. [Elektroda, ORMO_PL, post #16885096]

What did the original poster decide after testing options?

They chose to buy a 3.5-inch enclosure like the one recommended, resolving the issue and avoiding underpowered adapters. [Elektroda, baszawez, post #16885229]
