Reflashing to 1.05 has no benefits. Reflash to 1.06 (official firmware will no void the warranty). If you feel it is a hardware problem RMA it. If you feel it is a software problem, make sure you have the latest chipset drivers installed (do not install the NVIDIA IDE driver if you are with an NFORCE chipset) and try another recording program. Try the drive in another computer, if possible, before you decide it is for RMA.
