MD5 Hash value to check photo files?

11 Feb 2011 8:57PM
These are my ramblings...

I was thinking today, with my backups being on CD, DVD, HDD and the like is there a readily available program that will allow me to compute MD5 hash values for my stored files then periodically check them against my hash library to see if they have become corrupted, which will then allow me to check and possibly replace with another backup of that file.

I use Encase at work and check hash values and file sigs, just wondering if there is any software out there for light use such as this.

Anyone know?

I seem to remember that the DNG standard supports something like this..but I could be wrong.

You can create a hash for every file, so that when a bit changes so does the value. That way any file that has changed will be apparent. Seems a great way to check photo files.
