I've gotten annoyed with defraggers and VSS and boot-time screwing with restore points and so on, so I've given up on restore points, etc. Anyhow, in a previous thread I noted how after I moved the boot-time files to the start of the drive, that the directories were still being stuck in the middle of the drive when I did a Windows-mode defrag and placing directories close to the MFT. The UD developer wrote a comment or two about it but I think I just realized a piece of information he neglected to add that would have made it more clear to me. So, is the following assumption correct? Is that when I tell the directories to be placed near the MFT that the directories are placed BEFORE the MFT and not after it or the NTFS boot-time tab in settings files? I can now understand how the directories could not be placed before the MFT and get stuck somewhere else if the MFT (and NTFS boot-time files) are placed at the first available cluster (# 32). Is this correct? So, then, if it is correct, what would be the optimal placement for the beginning of the MFT (and boot-time files block noted in the boot-time defrag settings tab) so as to allow more than adequate supply of space for the directories of an entire system drive (of course taking into account a large number of directories and directory growth) ?? Would someone mind giving me a clue on this? I've also gone back to using only 4 KB cluster sizes and not the 16 KB needed for "proper" VSS use. Udefrag once again screwed me when I did a boot-time defrag with 16 KB cluster sizes and fried my MFTMirr and "forced" it to be re-sized to 4 KB and not 16 KB. So, with this information, where should I place the MFT and boot-time block of files so to allow more than just enough space for directories to be placed before/near/close to the MFT ? I'd appreciate a specific notation, not just someone telling me to calculate cluster sizes and directory size, etc. For example, my 365 GB system partition currently has more than 15,000+ folders and yet I'm using only 21 GB of space on the 365 GB partition. What would be a good way for this ? This assumes of course, two things: 1 - that yes, directories are placed before the MFT in this setup 2 - that placing the MFT and boot-time files near the start of the partition are best Help, please. Thanks all !!
