I have the same issue here. Not all drives show up in every option of Norton utilities:
Windows 7 professional 64bit
Processor Intel Core i7 2600K - 3.4 GHz
4 harddrives:
Drive 1 (C): 100Gb OZC SSD
Drive 2 & 3 (D and E): Internal 1Tb - SAMSUNG HD103SJ SCSI drives NTFS
Drive 4 (M): External drive 1 Tb LaCie firewire NTFS
DiscDoctor program only shows drives 1 and 4
UnErase program however shows all drives
SpeedDisk only shows drives 1 & 4
Why are my drives 2 & 3 not visible in every part of the program while in normal workingmode all disks function normally under Windows 7.
