i have 2 questions here: 1. i use NTFS for my hard disk since acronis secure zone only use FAT32. i know using 2 different file systems on 1 hard disk can cause problems like crash, slow down. That makes me hesitate to choose to create ASZ. does anyone experience any problem and whether i should create ASZ? 2. i created backup archives stored in a backup location on drive D. recently i decided to create ASZ. the thing is can i copy the backup archives in other backup location to ASZ? i need to recover my primary drive which has OS. without ASZ or with ASZ but nothing inside, i just can recover specific files and folders and the outcome is not perfect. P.S: after creating ASZ ,sometimes i got error message from Data Execution Prevention that 'windows explorer encounters problem and need to close' which never had before having ASZ. (i turn DEP on : system properties-advance-performance options-DEP). any idea ?
