Hello,
Your problem seems to be that you are using an SSD without a big
capacitor (or partially damaged one) to preserve writes on power loss.
This fact combined with how TRIM works could create that effect.
You can try this steps:
1) Copy file content to .bak
2) Create new file with data (.datnew)
3) Close file (This forces SSD to write to an spare block)
4) Delete old file (This forces a TRIM sent to the SSD)
5) Rename file to original name.
In step 4, the delete should send a TRIM which could force a SSD-RAM to
NAND-SSD write to handle the TRIM. You must not delete 0 bytes (no TRIM)
nor files with a size less than 1024 (no TRIM in NTFS as most of them
are stored as resident data in MFT).
