image on multiple media

I have to analyze the image of a HDD, but it is so great that it is stored on two HDD (1+1 tera).
When I try to upload the image, Autopsy return this error messages:

How can I resolve the problem? How can I set multiple sources for uploading?

Thank you and excuse me for my bad english…


It looks like the main cause is some kind of DB error (disk I/O error). Does the drive with the case folder have enough storage space? I’m trying to think of other reasons why there would be a disk I/O error when adding something to the Case DB…

I resolved buying a 4 TB hard-disk and saving the two image parts on it.
