Digital Cameras Photo Reviews of Sandisk MicroMate SD / SDHC Memory Card Reader (Static Pack, New, SDDR-113)Customer Review: Pretty good...if you're using a powered USB hub Summary: 3 Stars
Over the year and a half of having this I've found out a pattern to using this that may interest some people. If you connect the reader directly to a USB port on an iMac you will have reliability issues. The drive will unexpectedly disconnect and reconnect randomly. If you connect this reader directly to a Windows PC's USB port similar symptoms will arise though the speed of the data transfers and just loading the contents in a Windows Explorer window is noticeably slow. Once loaded the data appears quickly until the reader decides to slow down again, which is every couple of minutes. The reason for this is because the reader isn't getting enough power. Believe it or not there's not enough power on the powered USB ports directly on a PC to power this reader.
The way to solve this problem is to plug the reader into a powered USB hub. I have a couple Kensington Dome USB 2.0 Hubs here and the reader works fine plugged into one of them. Despite my microSDHC cards being Class 2, they work just as fast as my PNY 1GB Attaché thumb drive on a powered hub. This leads me to wonder if buying a different reader necessarily solves the under-powered USB port problem. I love buying the bulk package 8GB microSDHC cards because they're so cheap. I'd love to use a simple thumb drive-like reader that works with under-powered USB ports, but now I'm not so sure it would work.
[UPDATE] Another thing I found out is if you format a card on a Mac with Disk Utility, you need a powered hub. If you format a card on a Windows computer (either a real PC or a virtualized PC) the underpowered USB ports read the card just fine. Strange that there's a difference, but there is apparently. Macs must do something to the FAT32 formatting that Windows doesn't agree with. Even if you set the boot sector to MBR instead of GUID Partition Table or Apple Partition Map. So, the lesson here is to get yourself Oracle's/Sun's free VirtualBox and a copy of Windows XP or 7 to format cards into FAT32 volumes if you're stuck on a Mac.
