I have an external drive mounted on a Netgear Router and backup to that drive by using a VHD attached to the local Win7 Machine. However, the backup gets all the way to the end (c97%) and then fails with Error 0x80070570 (The File or Directory is Corrupted).
I have validated that the physical drive has no issues and have created a brand new VHD (using both auto expansion and fixed size options) and still get the same error. I read that VHD size might be an issue so also set the VHD size to 300Gb to backup a 120Gb local HDD.
Since the error always happens at the same time (end of the Backup) and the physical HDD doesn't have errors, the error message seems to be masking another issue.
I have also validated that if I attached the external drive to the local Win7 machine, the backup completes succesfully.
Any suggestions much appreciated!
