Hello Barbara and Peter, Thank you for a quick response. I tried what Peter suggested. Specifically: h5repack -L -f NONE 20120921.h5 /data/tmp/20120921.h5 h5repack error: <20120921.h5>: unable to open file h5dump -H 20120921.h5 h5dump error: unable to open file "20120921.h5"
Then I tried to open it again in HDFView 2.9 to confirm it opens fine. The HDF version I'm using is 1.8.10-patch1.

I saw that Peter responded to your same question on the HDF-Forum. We do not provide a way to restore a corrupted HDF5 file. You might be able to salvage parts of a file. What you can do is try avoiding corruption, by flushing data from memory to disk frequently. (See H5Fflush) However, it is not clear that your file is corrupted if HDFView can view it. Did you try Peter's suggestions? Early versions of HDF5-1.8 had some issues. Could you use the current release? -Barbara ==================== Barbara Jones The HDF Helpdesk The HDF Group [email protected] ==================== _______________________________________________ Hdf-forum is for HDF software users discussion.
