So, I have a 3.5 inch SATA3 interface Hard disk drive, and my sensitive information are in there.
I know SATA power has pins for 3.3V and 5V and 12V. Can I power it only with 12V external source?

  • Most likley no. – winny Dec 15 '16 at 14:57
  • You can certainly get away with 12V and 5V (i.e. no 3.3V), but not sure, check the hard drive labelling. – Tom Carpenter Dec 15 '16 at 14:59

    Just get a SATA to USB adapter. Should be less than $15 US. – R Drast Dec 15 '16 at 15:00

    I know of no hard drives that will work with only 12 volts. Some, mostly 2.5" drives, use only 5 volts. – DoxyLover Dec 15 '16 at 19:52
  • Why must you use only 12V? Can you stick a cheap 5V step-down regulator on the 12V rail? That'd give you the 12 and 5 volts the drive needs. – Sam Dec 16 '16 at 6:24
