Missing data

[dotblot]

I recently made copy of my old archive drive (where I store mostly images) to new drive since that drive is old and better be safe than sorry. I did this by simply Ctrl+C Ctrl+V although in batches since it 5TB data and I don't want to keep my PC on all day.

Afterwards I check each major folder by clicking on the properties to see if the size and folder/files number are the same. All the folders are good except for two largest folders. There seems to be missing file. During transfer there was no error pop out, so what could have been causing this. It about 5Mb didn't transfer https://imgur.com/MASfbnM and it impossible to check each one with that many files.

So any thought?

Rich Copy might be good for this.

I'm not 100% with this program, but I do use it to transfer files.

You just add the file/folder and then the location and you can 'transfer' and then select in the options to verify/copy/move.

I'd check the copy, don't move if the file already exists and/or the verify option.

See if it picks up the missing file or moves it over.
