Checksum error loading project 1.8 RC7

[RickS]

I saved a project with an image still locked (not sure how it got that way) and I was unable to reload the project:

*** Error: File checksum failed (961afd6837a5a3ccab0e102fb595699966d5969a): D:/Users/Rick/@Stuff/Astrophoto/Maxim/+130923 C300 Helix Nebula again/Project/Helix 1310.data/PLUXVEL13-000133
* Regenerating masking relations
* Updating workspaces
** Warning: The project has been loaded partially with 1 error(s).

Using Version 1.08.00.1023 Ripley (x64) RC7 on Windows 7.  I did check the disk afterwards in case there was a hardware or filesystem issue but chkdsk was 100% happy after spending 8 hours checking the drive.

Secondary question: is there a way to load a project and ignore errors?  If I could recover some of the data it would save me a day of reprocessing...

Cheers,
Rick.

I was able to edit the .xosm file and remove the offending entry.  The rest of the project loaded normally after that.

Hi Rick,

Recoverable errors are overcome by the project loading routines automatically. Unrecoverable errors cannot be ignored, since they are caused by malformed XML source code or inconsistencies that would compromise the whole platform.

A checksum error means that one of the project data files (on the ".data" project folder) has been modified since the project was saved. You can "ignore" these problems by simply removing the checksum from the XML code. For example:

<image src="@project_data_dir/UCGGY8P5U-000001" sha1="bb8ed859dfdfcc092246d010f86b7e2b9fb225de"/>

If you remove the sha1 attribute (marked as red text), the project loader won't verify the integrity of the image in question. Bear in mind that this may lead to further errors if the image is inconsistent with other project items.

Thanks, Juan.  That's good to know.  It turned out that the root case of the problem was a failing hard disk.
