Connect a 2.5" (laptop hard disk) SATA hard disk to Desktop PC

Can I connect a laptop SATA hard disk to Desktop PC? Do I have to use some adapters or I can just plug in SATA power connector and SATA data cable like my Desktop hard disk is connected?

I noticed that both laptop and desktop SATA disks use same connectors, but I'm afraid that I might fry my laptop hard disk because the SATA connector has both 12V and 5V voltage (given the fact that laptop hard disks has input voltage of 5V)

I bought a all-in-one Modex-to-SATA power adapter and SATA cable and I still don't know what to do.

I have read various forums and a lot of people are stating that it's perfectly ok, but some are scaring me that by connecting it so, it fried their hard disk. And some also mentioned cutting the yellow 12V wire if I'm planning to use Modex-to-SATA power.

Thanks in advance

According to the standard, SATA data/power connectors are universal and there is no risk of damage if you connect a 2,5" disk to a desktop system. I have done so countless times and never had a problem. I guess if people had problems, they might have had other issues with their setup.

You can connect 2,5" laptop-Sata-HDDs without any risk directly into your desktop-PC - no need for any workaround using USB which will slow down the transfer.

SATA is SATA and all SATAs are compatible (at least for now - though i doubt they'll change that...)

In fact, some servers use 2,5" drives to save space...

I recommend to use a USB external adapter for 2.5 HD.

But you can contact the HD manufacturer and ask to them, don't just take the risk yourself.

If this is a temporary need, I'd recommend an external USB drive adapter.

Something like this universal drive adapter would work well.

If you are trying to connect your laptop HDD to your PC permanently, then you should probably connect it directly the same way as you connect your desktop HDD. No need to cut any wires.

I've tried this and it works just fine.

UPDATE: Thank you for your answers folks.

Anyway, I decided I just remove the yellow wire from the Modex-to-SATA cable and connect the hard disk to my PC. I closed my eyes as I pressed the button. Works like a charm. I am transferring data now. Lot and lot faster than via Ethernet

Best regards
