Backup validation faikure
I have true image 2017 on 2 computers. one is a desktop the other is a laptop I can do a backup on my desktop using the system restore disk(2017) with validation without errors However when trying the same backup on the laptop i get a disk failure in the validation sectin of the program, this always happens. Hpwever if I leave the 2017 true image program on the computer and run the system restore disk(2016) I can do backups and recoverys witout failures using validItions.

Rudolph, even when using the ATIH Rescue Media (restore disk) - log files are created, albeit only temporarily when booted from CD, so you should check the log before exiting from the media - you can also save the log file to your hard disk or a USB stick. This should give a better idea of what is happening here.
Also, if you are using Rescue Media, please ensure that this if from the latest build 5554 version of ATIH 2017, this may not be so if you are using an Acronis install CD provided when you first bought the 2017 version.
Assuming that you have ATIH 2017 installed, then you can create the Rescue Media within the application using the Rescue Media Builder program in the Tools section.
If you have the latest build version of the Rescue Media and still see this issue, then you should open a Support Case directly with Acronis Support to have this issue investigated further.

If it's working with the rescue media and not in Windows, my guess is that you have a VSS issue on the local OS. Since 2015 and newer, the default backup method is now VSS (volume shadow service). In 2014 and earlier, as well as the offline rescue media, the backup method is the proprietary Acronis Snapapi method.
So the differences are:
1) ONe is an online backup using snapshotting and the other is a completely offline backup where the drive is idle and no OS is actively running, nor any Windows services or third party applications that might potentially be interfering (some antivirus programs can interfere as well as can malware when the OS is running).
2) VSS is a Windows service and can have it's own set of problems in the OSS - it is not uncommon for VSS to have problems.
I would suggest that you try disabling VSS for your backup and letting it revert back to the proprietary Acronis snapapi method and see if it then works in Windows as well (or not). It's simple to do and the backup is just as good as VSS. VSS only has an advantage of backing up open/live SQL or Oracle databases, which most home users probably aren't using. Even so, based on my experience with both databases, I would not rely on any backup of that database that was taken why it (oracle or SQL) was active. In short, Snapapi should be just as good and you should try that as the backup method instead. You can do this by opening up the backup script with notepad and making the following change:
1) open the folder where your backups settings are saved: C:\ProgramData\Acronis\TrueImageHome\Scripts
2) each file there stores settings for particular backup job. Open files one-by-one in Notepad, or open latest modified file (if you have just modified your task), until you find the one that has backup name on 5th line, e.g. MyBackups
3) click Edit - Replace and replace use_vss="true" with use_vss="false"
4) save changes and close the file

Rob, my understanding from Rudolph's posts is that he is only using the Rescue Media and not doing any backups from within Windows for this issue, plus that the problem only shows when using the ATIH 2017 Rescue Media but not with the 2016 media.
One suggestion to Rudolph in addition to my last post above #3 is to deselect the option to do an automatic validation of the backup - just keep to doing the backup then try doing a separate validation after the backup is reported as successful. This has been an issue over several versions for some users. I personally do not do combined backup & validation tasks - the validation is no more than a recalculation of the embedded checksum value for the backup image file. A more realistic validation is to attempt to navigate the contents of the backup image file (either in Windows Explorer, or mounting as a drive letter etc) and perhaps restore a few files / folders to a temporary location to prove that the backup is good and can be used.

Did you run chkdsk /r on each partition of the internal drive, and on the external HD, and separately on hidden partitions? I know you said that the drives have "no errors", but I don't know if you ran the tests or are simply asserting that the drives are fine. Forum users seeking help sometimes claim that everything is fine, rather than run the tests that we recommend, and later it turns out that everthing was not fine. Tests can be useful even if they find no issues, as that helps us rule out some possible issues.
