Postup řešení

  1. 1 Press Windows key + R, type 'devmgmt.msc', and press Enter. Expand 'Disk drives' and find your network drive (it may show as a local disk).
  2. 2 Right-click the drive and select 'Properties'. Go to the 'Policies' tab. Check 'Enable write caching on the device' and 'Turn off Windows write-cache buffer flushing on the device' (if available). This can reduce data loss but may increase risk of corruption if power fails.
  3. 3 Alternatively, uncheck 'Enable write caching' to ensure data is written immediately, but this may slow performance.
  4. 4 Ensure your network connection is stable. Use a wired connection if possible.
  5. 5 If using a mapped drive, consider using a VPN or a more reliable network protocol like SMB3.
