Hi all. In a previous thread: https://www.wilderssecurity.com/showthread.php?t=164157, 'Lowtrawler' writes; "Unfortunately DDS uses an older version of NTFS than Vista and so all disk changes made by DDS are likely to be incompatible with Vista. The most worrying thing though is that problems often don't manifest themselves straight away, it can take several days of use. Hence, you can make the disk changes, believe them to be successful and then lose your system a few days later. Quite simply, don't use DDS with Vista." Well I partitioned and formatted exclusively to NTFS a new 320GB SATA II WD HD using DDS10 bld 2117 (current build), then installed Win XP Pro on C partition with swap file moved to D partition, user data on E partition and TI10 bld 4940 backup images on F partition. Planning to shortly install Vista Ultimate to the same C partition, not as dual-boot, but one-at-a-time via restoring from TI10 images of XP or Vista. Vista swap file planned to also be on D partition. Some questions I need answered: * How many partitions would need reformatting using Vista (or XP?) for this system to be stable against the 'Vista slow corruption' problem identified above? * If D partition needs reformatting, would resorting to standard arrangement of swap file on C partition be advisable, or is a once-only reformat sufficient? * Suppose I create an image backup of say Win XP on DDS10 formatted C partition using TI10, then restore it with TI10 to same partition in the mean time reformatted using Vista. Does restored XP image have Vista or DDS10 format version? I presume it's the latter but not sure. * Is the problem one-way only - ie Win XP works fine on Vista formatted partitions? Any answers will be most welcome.
