I need to know the power rating for a Maxtor 160GB external Hard Drive for use with a Yamaha PSRs-900 keyboard. Yamaha requires the rating to be not greater than 500-600mA
The Maxtor STM901601EHD301-RK is part of the Maxtor Basics Portable family.
It uses a 2.5 inch Internal harddrive inside. (2 and a half inches across the Width. Same size used for a laptop. Desktop's use 3.5)
It connects with a USB Style A male plug, via the USB cable.
It's has a 160GB storage capacity, has an 8MB Buffer, (Cache), and an External Data Transfer Rate of 60 MegaBytes per Second.
Other than that, I find no more information from Seagate, (Seagate bought out Maxtor, and has the data base for Maxtor products)
What I do know in reference to your question.
I know that the USB 2.0 technology uses 5 Volts DC. The Positive pin on the USB plug will support up to 5 Volts.
[Viewing a USB-A style plug, view it with the white plastic spacer at the bottom. Open part at top. The Positive pin is all the way to the right. The Negative pin all the way to the left. The Data + pin is on the left next to the Negative pin. The Data - pin is on the right, next to the Positive pin]
The Maximum current draw is 500 mA for a USB 2.0 port.
[ Current is rated in Amperes, or Amp's. You are looking at Millionths of an Amp.
Milliamp, or abbreviated as mA]
This would lead me to believe that the Maxtor Basics Portable external harddrives will not use more than 500 Milliamp's.
However I do not feel comfortable, telling you that it is okay to use your Maxtor STM901601EHD301-RK, on your Yamaha PSR2-900 keyboard. Would hate to be mistaken, and have you burn out the finals of your keyboard.
I do feel comfortable with the following suggestion.
What about transferring as much data as you can from the Maxtor Basics Portable, to a USB thumb drive? They have large thumb drives now, and hold a lot of data.
Most programs will fit on a large USB thumb drive.
Or am I missing the point somewhere?
