i have a 1 gb sandisk flashdrive i am using for eboostr. my question is ,can i clear the cache on my flashdrive ? program shows cache fill to be 100%.does this mean the program is no longer working because my cache is full,or does eboostr delete old entries as needed to clear space for new ones? i am currently waiting for an 8gb flashdrive from ebay with 7000kb read speed.if the cache fill on this drive gets full, will the program still work properly?
