freddo7 Posted February 17, 2019 Report Share Posted February 17, 2019 O/S - Windows 10 Home 64 bit Retrospect 12.6.1 Desktop for Windows. Back up device - Western Digital Elements (3TB) I got the following error message for an incomplete back up.

freddo7 Posted February 17, 2019 Author Report Share Posted February 17, 2019 Just an update to my topic. I had the Ext HD connected to the following device: [2nd Gen]TP-Link 9-Port USB 3.0 Hub with 7 USB 3.0 Data Ports and 2 Smart Charging USB Ports. Compatible with Windows, Mac, Chrome & Linux OS, with Power On/Off Button (UH720) I decided to run the back up job connected directly to the computer and it completed and it is currently comparing the back up. So it may an issue of the hub. The hub is A/C powered. Quote Link to comment Share on other sites More sharing options...
Lennart_T Posted February 18, 2019 Report Share Posted February 18, 2019 From the error it looks like it is your C: drive that causes the problem ("can't read error"). If it was the destination, the error should say "can't write error" or something like that. I would check the C: drive, both the S.M.A.R.T. status as well as doing a surface scan. (Windows CHKDSK does not do a surface scan.) Quote Link to comment Share on other sites More sharing options...
kidziti Posted November 12, 2019 Report Share Posted November 12, 2019 Do you have a recommendation for a program that can do a surface scan and mark the sectors? Quote Link to comment Share on other sites More sharing options...
