Pismo drive amperage rating?

Message #1 - Posted 2006/09/10 - K

Advice appreciated:

In a Pismo, 500 mhz, 1 gb ram, Tiger 10.4.7. I'd like to install a 40 gb Toshiba MK4032GAX hard drive.

However, a retailer told me that a Pismo requires a hard drive using LESS than 1.0a as the amperage, or the drive will run hot, use up the battery quickly and the hard drive will fail in a few months.

Has anyone found amperage to be a concern with a Pismo hard drive? Thanks.

I have a Seagate Momentus 40GB 5400RPM drive in my Pismo. According to the data sheet:

It's power requirements are 1.2amps and haven't noticed any problems related to heat, battery and I've had the drive for over a year and it's still working. Although I will admit that I don't run my laptop on battery all that much.

And if you're using a Toshiba, there apparently can be a problem with ATA-6 drives on a Pismo.

I don't know if it's correct, but it might be a concern.
