Silverfast * file corruption

I am scanning a large library of old photographs using Silverfast and a Nikon Coolscan V.  Some files I scan into the Silverfast archive format '64bitBit HDRi RAW' so I can process them later.  

I recently installed Lightroom to try it out to help with photo management .  However, I have found it is corrupting the HDRi RAW files so that the dust and scratch application of Silverfast (iSRD) no longer works.  All my archive files have been corrupted, I assume Lightroom has been doing a background search of all my photo's.  This has cost me several hours of scanning work, I now must rescan the archive files.

In a search on line and I found one article which mentions Lightroom changing the file metadata and thhis causes a problem for Silverfast.

Has anyone come across this problem? Is there a solution?

Thanks

I think these files are designed to be used in the Silverfast software. As I understand it they are not conventional raw files but unprocessed scans which can later be adjusted in Silverfast rather than doing everything at the time of scanning. I don’t use that scanning software personally but I’m guessing you would need to output a 16 bit tiff file for editing in Photoshop, Lightroom or ACR. Do Silverfast not have a support desk or help forum?

Many thanks for responding.

You are correct and I use Silverfast for processing their unique raw files. I installed Lightroom primarily for library management and editing of JPEG and ordinary TIFF files.  What is really upsetting is that Lightroom appears to have scanned my entire hard drive in order to catalogue the files and in doing so corrupted the Silverfast raw files.

I have also contacted Silverfast to ask about this problem.

That probably isn't the case because Lightroom doesn't modify your files at all. Any changes made to images in Lightroom are stored in the catalog. Lightroom is a parametric editor which means that it does not directly modify the master images in any way.
