I recently purchased a WH10LS30 which came with firmware 100.07, since I could not find 100.07 online I used 100.06 and MCSE to remove speed lock. Now i get great transfer ratres for the first half of the disk, but then get speed drop outs throughout the rest. Has anyone else seen these? Could this be an artifact of the disk I am using to test? I have swapped the drive for a new one and I get the same results. These samples are taken from a single layer retail version of Splice.
I have attached the discspeed results.
