You have an excellent plan there, loading the card in several-gigabyte chunks. I always cringe at mass transfers, as the odds increase markedly for problems. I remember the days of filling a backup 10MB hard drive all at once. Ah, the old days.
Now, we’re into the gigs!
Let us know how the process goes! It will be eaasier to locate a problem by loading in increments.
