Compared against the e200 series, which have a mechanical wiper for the scroll wheel, the Fize and View have a softer scroll wheel, which is a combination scroll and “rocker” for the four main button functions. It feels looser, as it must both rotate and allow rocking for the button functions.
The charging function is interesting. Remember that the Fuze’s processor handles both battery management and communication, and if there’s a problem on the data side, the processor may be diverted from charging.
The most robust communications mode is MSC, in which the Sansa is seen by the computer as a flash drive. MTP, or Media Transfer Protocol, is a mode requiring Windows Media Player 10 or later, in which the Sansa is seen as a media device.
In either mode, you can see if charging is progressing normally by looking at the battery icon. When charging, you’ll see the connected logo, and the rolling arrows, or with the latest firmware build, the scrolling four color sansa logo. As the battery charges, the lightning bolt is displayed, plus the green battery will flash. When done, you’ll have a solid green battery.
If the computer cannot provide enough current to the device, or breaks the communication session, charging may be interrupted.
If the device is plugged in, you can open the Device Manager in one of many ways, either via Control Panel > System > Hardware tab > Device Manager, or by starting with the shortcut [Windows Key] + [Pause/Break] then follow the same line.
If the Sansa is connected in MTP mode, you’ll see it listed under Portable Devices, or in any case (including MSC) it is usually found as one of the bottom devices listed in Universal Serial Bus Controllers, as one of the hubs. Look for any wee yellow triangles, meaning that there’s a problem communicating with the device.
Often, the front-of-PC USB ports are connected with a cheesy jumper wire, and won’t supply the needed current for the Sansa. You can try using one of the rear mounted ports.
