I have recently purchased 4 new SanDisk Cruzers (4GB) that were on sale at Radioshack. I can tell you this now, I certainly do love these USB’s. Nothing else looks as sleek as these, but at the moment, it is not the case. I have just noticed different LED behavior on two different models (however both are still 4gb).
At the moment, I have a BH1003OBWB which I have formatted for use on my Xbox 360 as external media. The LED behavior seems fine when it is writing data to the device (around 2 blinks per second if I’m timing it correctly). To me, that seems to be normal behavior to the SanDisk Cruzer.
The devices I bought at the Radioshack sale are BH1010OHUB. These USB’s seem to blink around 6 - 8 times per second while writing data to the device. I was wondering if this is normal behavior to the devices? Or should I go back to the radioshack and return the new devices?
