I don't have any control over where the FTL decides to put the data but it should be block-aligned. And of course it does always play properly after a format. From the outside no data seems to have changed. The FAT is the same, and files match the originals As James has mentioned, a lot of the FTL's activities are not able to be accessed and examined. All that's available is the user interface. If the FTL is playing up there's not a lot you can do about it Joe ----- No virus found in this message.
