Moving Large Buckets to Larger Hard Drives

[Ketterman]

Hello DAM people,

I've just moved a lot of files into a much larger and more scalable hard drive set up (about 1TB of RAW (dng) files and about 1/2 TB of derivative files onto their respective new hard drives - as per my hardware discussion:http://thedambook.com/smf/index.php?topic=4700.0).

I moved all that data using Retrospect to copy the data and verify it byte-by-byte.  Took about 12 hours for the 1TB of raw files.

Should I be concerned with verifying my image data any further before I zero out the old drives?  I've been browsing the forum a bit here and see a lot of talk about ImageVerifier.  Many of the relevant topics seem to be 2-3 years old.  Just wanted to see if anyone had some advice or opinion on the issue.

Thanks for your help!

Ryan,
If you performed a validated transfer, and the new drive is behaving properly (and the other backups are in place and seem fine), then I'd erase the old drives and move on.

ImageVerifier is really only for files that are not ever going to change. Once anything changes - even the addition of a single rating star - the checksum reports a mismatch.

Thanks for the reply, Peter.  All the HDs seem to be working just fine.  My new system seems very robust and I'm quite happy with it.  I actually did a verified transfer and then ran the ImageVerifier as well.  Took a few nights of running things through the night, but it all seems safely moved.

Ryan,
Sounds good. Hopefully the safety and peace of mind are worth the effort.
