I got a hard drive, external case and Arconis True Image. When I backup manually, I do not get errors, but the scheduled backup gives me this: "E00070003: Failed to Read data fro disk. A possible reason might be bad sectors on the disk." http://www.goodgeeks.com/images/arcronis_error_E00070003_09.jpg a. I have run scan disk on both the source (c) and the external backup drive. Neither showed any bad sectors or problems. b. I am using a Firewire connection. I have two firewire ports and I have tried them both. I tend to think that my Firewire port(s) are going to "sleep" or something as my autmated backups are at night. Does anyone have any ideas or suggestions? I put in a trouble ticket, but have not heard back. Thank you for any help. Paul Chandler, AZ P.S. I believe I have attached a screen shot and the log file.
