You copy by dragging.
The progress bar reached the end. How do you know all 48 files made it without an error? You do not. Finder never compares bits.

Copied ≠
verified.
flow ingests cards from set and verifies every copy with xxHash64 checksums and an ASC MHL report. In Pro it writes a 1:1 copy to two drives at once. From card to certainty. One process.

01 / problemwhere you are now
Finder is not an ingest tool.
You format the card before the next shoot.
If the copy had a flaw, you just erased the only original. You find out about the broken file in the edit. Or from the client.
The client asks if the footage is safe.
Your answer is yes. No report, no checksums, no proof. Just your word.
The global film industry solved this years ago. Checksums and an ASC MHL report. The same standard now sits on your desk.
02 / processfrom card to certainty
You plug in the reader and watch the process close itself. flow does not ask. It leads.

03 / proofafter the import
The green check is not decoration.
It closes a process you are responsible for. You know what was copied, where the footage sits and whether every copy is identical to the card.
48/48
A copy without interpretation
The original media structure lands in a predictable project tree. Nothing is shuffled or "tidied up" for you.
Bit for bit verification
xxHash64 compares the source with the copy, file by file. Instead of assuming the transfer worked, flow checks it.
Mirror to a second drive Pro feature
The backup does not happen "later". It happens inside the same process: an automatic mirror copy on a second, independent drive.
Proof that stays
An ASC MHL sidecar with every ingest: file list, checksums, result. The standard of global productions, inside your project.

04 / your quoteyour edge
Your client gets this.
And pays for it.
Footage safety is not your internal cost. It is a line in your quote your competition does not have: a verified process instead of a promise.
You can paste the paragraph below into your own quote word for word. Seriously, it is yours.
"We ingest footage from set in a controlled process: we write a 1:1 copy to two independent drives, compute and compare xxHash64 checksums and save an ASC MHL report. Every ingest ends with a result we can verify, not with a declaration."
This wording assumes an active flow Pro plan, two target drives and a completed verification.
