Hi Dave, At our library we use the following tools (links below to our guidelines) to confirm transfer of digital files. I personally haven't used these tools with such a large dataset as your's but might be worth testing.
Robocopy (Robust File Copy) for PC http://tinyurl.com/ke9esag rsync for MAC http://tinyurl.com/kgoqb2c then for confirming no changes over time, we use checksums generating tools such as DROID (then compare using Excel) or Quickhash [1] Here some helpful explanation of using checksums, _File Verification using MD5 Checksums_[2] Hope this helps, Monica Quoting "Bigwood, David" <[email protected]>:
Open for suggestions for a fingerprinting tool. I think that's what they are called. We are copying NASA imagery to make available to the public. They send us a hard drive with about 10,000 images and we copy them to a drive then return the original. I'd like a tool that would compare the 2 drives to make sure everything was copied correctly. Then something that would be able to tell if some file had degraded, went missing or been changed over time.
