About a month ago, I setup a full partition backup against my Windows partition ( about 244GB ). After that was successful, I then created incremental and watched it go for about 3 weeks before it started throwing this error. Nothing works now as any file I/O for new backups and restores get the error: Error: 65571 ( 0x10023 ) Can't open/create file Platform: Windows 7 Pro SP1 Source: local SATA 480GB SSD ( primary windows drive ) Destination: local SATA 380GB HDD ( d:\paragon_repository ) The files are accessible using windows tools. I have tried running the application as Administrator, chkdisk, sfc, and other remedies. Thank You for reading, -weq
