Regarding our previous report of problems with APS Tools 4.0.9, several readers reported getting the following response from APS (the situation, as I had implied, is similar to what happened after their prior update):
"The 4.0.9 version of the APS PowerTools driver is larger than the earlier 4.x versions and in some cases will not fit in the driver partition created under the earlier version. When this occurs, the only resolve is to either stick with the earlier version or, initialize the drive with the new version. This will write a new driver partition that will house the larger driver. Please note, this will erase all data from the drive so make certain you have a backup of all necessary information."
