About PGP Whole Disk Encryption
About PGP Whole Disk Encryption, I know that pgp wde work sector-by-sector enccryption when wde start first time. but i donot understand really wde encrypt sector-by-sector?
when i start wde encryption on my pc's hdd 250GB, wde encrypt all it to 250GB. this disk has 100GB data and 150GB is not used free space why wde doest not encrypt sector-by-sector? if wde encrypt whole disk space at first time when using sector-by-sector method?
other question is when i off the pgp wde service and write new data on my disk how wde work? when wde encrypt it?
if anyone know it please let me know. thanks.
