I understand USB2.0 should max out at 480 mbps which is about 60 MB/sec. I am averaging less than 4 MB/sec transfer speeds which make the drive virtually unuseable. It is the same when hooked up to two different computers. One is a newer Macbook running Windows 7 32-bit. The other is a desktop with an MSI K9N2GM Motherboard with the newest firmware update and the newest driverset for the nVidia chipset, running Windows 7 64-bit.
I do live in Japan so the power adapter is only running at 100v and 50hz instead of 110/120v and 60hz like in North America.
I’m tearing my hear out here. I have tried everything including trying different USB ports on both computers. Checked the BIOS for incorrect settings. Sometimes I can get it to work properly in the neighborhood of about 35-40 MB/sec transfer speeds, but it is very short-lived and quickly drops back down to 3-4 MB/sec.
Is my drive defective?
