Transferring data from an SSD to NVMe involves additional files for the 40GB expansion.
Transferring data from an SSD to NVMe involves additional files for the 40GB expansion.
Attempted to clone SSD to new Samsung Evo 960 NVMe. Used Samsung data migration and it functioned well again—until storage exceeded 43GB extra files. Tried Spacesniffer but found nothing. Disabled hibernation and paging file. Any fixes?
System: Alienware Alpha R2 - Windows 10 - i5 - 8GB RAM - Samsung Evo 850 (main drive only 19GB, recently reset)
Consider using WinDirStat. I haven’t relied on SpoofSniffer much, but it’s reliable for tracking unused space. https://windirstat.net/download.html
I just tested it and it displays just 19,0GB on the C: drive, almost like Spacesniffer (only 21GB). That’s odd since When I open This PC it shows more than 60GB used.
Consider everything on the drive, click right-click → Properties to view the displayed size. If it still shows 60GB, try selecting half of the folders and check the size, then reduce the folder count in half repeatedly until you locate the misplaced file. It's also possible Windows is mistakenly reporting disk usage.
Opt for another approach rather than editing this post. A fresh installation might be better. I usually don’t rely on migration tools; instead, I back up what I need and move it to new hardware. If you manage to back up your data, I strongly suggest doing so (it seems like there’s a lot to transfer).
Verify identical file system and consistent block sizes across both drives. Variations may explain significant differences in used space.
