PerfectDisk 14.0- does not support the huge MFT. How to work around the problem?
makinero:
Boggin - Do you realize that every tool to defragment the MFT - not fully defragment files and MFT when running low on disk space for example.
[VERY LARGE MFT | small files] requires more than 25+GB (500GB)...50+GB(1 TB) (minimum 5%) of free space (!)
For the limited fragmentation that can still occur, PerfectDisk's patented SMARTPlacement optimization strategy optimizes disk drives according to your unique usage patterns. SMARTPlacement results in the most consolidated free space available, the elimination of most fragmentation before it occurs, and a reduced rate of fragmentation.
SMARTPlacement Technology = work for me full defragmentation even if an drive very little space, eg. 10 GB (for large partitions)
Boggin:
Why not free up some space then by copying large stuff to an external HDD.
To do a normal defrag I think the min free space is 15GB.
You can free up 6GB by turning off hibernation with the elevated cmd - powercfg -h off or powercfg.exe /hibernate off
Running Disk Cleanup as an admin will also reduce the WinSxS folder of obsolete Windows Updates if you don't normally or haven't done that.
I think I got back about 3GB when I first did that - talking Win 7.
You can also run Extended Disk Cleanup which will give you more options. http://www.sevenforums.com/tutorials/76383-disk-cleanup-extended.html
You can also use the free version of CCleaner to wipe the free space. https://www.piriform.com/ccleaner/download

Many of the tools to defragment:
Uses very, really a lot of RAM (memory leaks)
Example: Defraggler64 - use 14 GB RAM. This is the pure truth! Servers, or some desktop PC (eg. On my PC).
and.. It requires 10% free space
600 GB -> 60 GB of free space ... This is pure truth!
O&O Defrag Pro - I could repeatedly prove that the service can simply hang... but it works quickly defrag and does not use a lot of RAM.
Smart Defrag - NOT perfect tool and authors of the program announced that in the future the old to improve application and allow 100% fragmentation.
You can not fully defragment the disk or defragmentation takes a very, very long (just algorithm is tragic) even if a lot space.
It does not interest me: that someone has a small hard drives and little data!
I do not care that someone offers me delete important data!
Boggin:
I'm not asking you to delete important data but to move it elsewhere to free up space while you want to do what you want - but it's up to you.
I can't offer any further advice on this so I won't.
Julian:
several million files woah damn i'm curious how many fragments you have on the MFT lol the most I've seen or not really seen was Shane having 5 MFT fragments
