We tested a bunch of 2.5" USB powered packaged drives and found that the ones that came with extra cables to steal power from a second USB port didn't work on Touch with it's single port.
All the drives that only had a single USB port and no extra connection for power worked fine. The drive you mentioned has a 4.7W startup power requirement, which is 940mA, way over the 500mA USB limit. The touch can provide a bit more than the limit (750mA, if I remember correctly), but this drive probably won't work, unless you have an enclosure that's doing some clever power management. -dean On Nov 23, 2009, at 4:58 PM, gharris999 wrote: > > JJZolx;488558 Wrote: >> Only that you may want a 2.5" drive.
