Is it possible to make an old internal 3.5" SATA drive into an external (self powered) ESATA connectable drive with the option of usb 2.0 connectivity for times when i dont have an e-sata port?


Also, is it possible to make a self powered 3.5" SATA to usb 2.0 enclosure? (possibly with 2x usb plugs or just 1 would be best)


Thanks for any info you can shed on this, and in-depth explanations are not discouraged as Im curious to know why this is or is not possible.

Hi drwmbt,
Cases with connections and cables to contain a 3.5" drive to be used as an external drive are available. You'd have to check with the vendor on which connection is used. I use an external SATA with a USB cable as my backup drive.
I have not seen an adaptor to convert SATA to USB but then I haven't looked for some time at the various conversion adaprots that are currently available.
Keep us posted

I would have to say not to likely.


The Problem is that a USB2 port has a 5 volt line that can supply 1/2 Amp maximum.

USB3 is a I believe 900Ma (9/10 amp) and that is not enough power for the electronics and the drive.


The second problem is that the 3.5" hard drives need 5 volt and 12 volt power and USB does not provide both, Only 5 volt.


The external Drive makers either provide a external power adapter or if they are designed as portable, Then they use laptop drives that can run on the 5 volt power from the USB port.


I hope this information helps.
