Flash drive/memory card not able to use readyboost

[jnelsoninjax]

On my Toshiba laptop when ever I plug in a flash drive or a SD card, and choose readyboost, I receive this error:

My laptop is running Home Premium 32, and the flash drive is an OCZ Rally2 16GB, is there a reason for this?

If the drive is not rated for ready boost it simply will not work

Sometimes under powered usb ports, usually not 2.0 will do that. I have a Patriot Xporter 16gig that is definitely readyboost, even Patriot says it themselves, what happens when plugged into front panel? Not readyboost able. Connect it to front readyboost able.

Even thou front panel is 2.0 in my case, theres just not enough power. The rear panel always has direct power.

As far as a laptop goes, I say try a different port or if you have to laptop / desktop. Also make sure its "rated' for readyboost capability. Usually that doesnt matter as my old 3-4 year old drives still do readyboost, some cheap ones just arent meant for heavy use and readyboost is heavy use/.
