I have a serious problem with my 16gb PNY Attache flash drive. Every time I try to write over 1gb worth of data, it stops in mid transfer and acts like its not connected anymore. I have to disconnect it and connect it again and transfer less than a gigabyte of files at a time. Also when I try to read something fromit, transfers start at 25mb/s and a minute later it starts dropping of until 390kp/s or so... Ive tried it in different computers and operating systems (32 & 64 bit) and it keeps doing it. Any help would be great!
