After deleting partitions from my FreeAgent 250, Windows disk management will no longer see drive. Even tried booting to WinXP setup to see if it was able to be partitioned/seen and it causes setup to freeze when detecting Windows. Was working fine prior to deleting partitions. SeaTools diagnostics doesn't recognize the drive even though it is properly recognized in device manager. I suspect if there is a way to run a low level debug on the drive it could be restored but I don't know of any way to do this on an external usb drive. If there is no way/utility to run this, does it sound like the drive is toast? It's only a few months old.
USB boot does properly function on the computer in question so drive should be and was previously recognized in Windows setup.
There is no clicking, power and usb is good.
