I have following scenario.

Windows 7 with 1 TB disk, shrink-ed to about 500 GB. Used space is 200 GB.
I am trying to consolidate free space, but it does not seems to work beyond 500 GB.

Windows 7 have small empty partition 100 MB in front of the big one.
(similar to Linux's /boot ?)

Windows 7 is NOT UEFI Boot (system have legacy boot) and 500 GB partition is marked as active

SSD 250 GB

I have Linux running where I can attach both disks.
Can I migrate the data somehow with copy (from Linux), so at the end Windows 7 to be able to boot from the SSD.

I know I can do it if it were Linux, but I have no idea how Windows 7 boots and what I need to dd


Is the remaining space unallocated?

Sounds like you need to go to System Management > Disk Management and partition the rest of the hdd

hope this helps

  • defrag /x not seems to consolidate everything. shrink stays at '600 GB'

  • @Nick tried disabling pagefile (virtual memory) and powercfg /h off before defrag?

You can backup the 1 TB disk and restore to SSD.

Be sure to include System partition as well as OS partition in backup.

I have used the free tool Macrium reflect, there are other free tools offering same functionality. Be sure to select the option to backup only occupied by files partition space.

During backup disk contents is compressed so you need far less than 200 GB on external media for storing the backup. You can even do the backup to your 1 TB disk (in the freed space).

As a bonus you will have a complete backup of your system so you can restore in case of system failure.

Just a suggestion - there are relatively cheap external USB 3.0 disks for backup. You can even install to and start Windows 10 from such a disk (newer Windows versions can easily be installed to USB drives, aka Windows 2 Go).


Here is how I did it 3 days later :)

I tried several times with Microsof Defrag, using -X option. Unfortunately it does not worked.

Then after a backup, I installed Auslogics Defrag Free. I found out, that this program can not consolidate the disk space. However it show very clear what files are positioned at the end of the disk.

Since I am lazy and did not wanted to clear all files by hand, I installed Auslogics Defrag (Paid). But I found it still have no free space consolidation until you actually pay.

Finally, I installed Perfect Disk trial. This program consolidated the space.

Finally I shrink the disk and dd it to the SSD.
