I've found when mirroring from an NTFS volume to a FAT32 volume that size+time alone doesn't always cause modified files to be mirrored. Can you explain how the DOS date/time option checkbox should be used and when it should be unchecked.

In an effort to avoid this problem happening again, I've reformatted the FAT32 volume to NTFS and leave the DOS checkbox unchecked. It seems to work better.

Thanks.

DOS date/time option truncate time to seconds. For FAT32 it's not important. But for NTFS it's important, because NTFS store modification time more precisely. If you use mirror from NTFS->FAT32, it's hard to determine using only time, was file modified or not. Disabling DOS date/time guarantee what ICE Mirror will always copy modified files. However, sometime ICE Mirror can copy files witch not need to copy. It will waste your time.

how would you say its not important for FAT32, have you test it out earlier ? Is it fine with NTFS ?

DOS option need only for comparing files with different file system: NTFS vs FAT, NTFS vs CD-ROM
