Powering the Pi Questions/Observations

If I connect power into my 512MB Model B Pi via one of the two USB ports and attach a USB Wifi dongle to other port, Pi boots fine and Wireless works fine. In this mode, Kill-A-Watt indicates I am drawing 4W (probably not very accurate). If I supply power via the normal microUSB port, the USB Wifi m...

Seagate GoFlex Sateliite/Lapdock?

I have used my Raspberry Pi often connected to my Lapdock with an external USB 2.0 spinning drive which is also connected to the Lapdock. Since the Seagate GoFlex Satellite drive has an internal battery, it might be a good candidate to use in lieu of my current drive. I would need a modified cable s...

Re: ext3/4 and SD-card wear leveling

Still, the SD protocol (as opposed to the USB mass storage protocol) has block erase commands, and the controller might take advantage of them. I agree with your post. From my reading some (but not all) SDHC cards support block erase from the computer side interface. If the the SD Formatter 3.1 win...

Re: ext3/4 and SD-card wear leveling

If forum members have found SDHC cards that actually do something with the trim command, I would like to know which ones do. The Trim command is an ATA command that can be sent to an SSD controller telling it which NAND pages (usually 4K in size) have been deleted in the file system. If the controll...

Re: LapDock with rev 2 (512MB) Pi

Update: The Pi does not crash if I plug in my USB Wifi dongle after boot; however, it will NOT complete the boot process until I unplug the USB Wifi. So I guess we need to make sure USB Wifi dongles are not plugged in until after a successful boot.

Re: New Raspbian slowed down

How do we confirm that the latest Raspbian has the new kernel/firmware that works with the new Video License codecs? If it does not, what files should I save from the vfat boot partition (assuming they would work with the latest Raspbian download?)
