Corrupt files/ CFAST card crashed?

PostThu Sep 21, 2017 8:05 am

Hi Guys,

I did a project on two Transcend CFast 2.0 CFX650 256GB. I played them in my Ursa Mini Pro, but when I tried to copy them to my MacBook Pro, I could copy the file but couldnt open it. I can see the tumbnail, but can't import in Premiere Pro or Finder or VLC. I shot it in 4K 422.

The other card is even worse, it won't connect to my macbook pro (it was mac foramtted in the camera) and when I put it back in the camera, it said it needed to be formatted.

Any ideas?

Which card reader are you using?

Lexar CR2, but the other card it did take. The strange thing is, I can see the shots on my UMP and play them, so they are there on the card. But I can't see them on the computer

There is a known problem with the Lexar CR2 and CR1 under OSX, leading to corrupt card filesystem structure.

It happens when you do not eject your card before removing it.

That is not possible, no.

I detailed my experience with an unmountable CFast card here:

viewtopic.php?f=2&t=53174&start=50#p361683

I tried every known path to a solution, including more expensive apps like Data Rescue and Drive Genius, and none even recognized the card. Disk Drill saw my card and recovered everything. I would download the free version, run the “all methods” recovery mode and if you see your files (check that it shows you the size in GB and preview the files, it’ll show you a thumbnail preview), then you can decide whether it’s worth purchasing the full app so you can retrieve them. It was for me.

Good luck,

1. While it's not recommended there _IS_ a way to connect the CFast card directly to the PC. It also applies to some Lenovos. I mean - use a removable drive rack and SATA/CFast adapter in it. If your notebook has ESata then you can attach your SATA/CFast adapter here.

2. If you use The Operating System which MACOSX surely is and not an abomination named Windows then there should be a method to mount the card manually and read-only. Always use this method unless you really MUST write something to the card.

3. Unfortunately the SATA (CFast is SATA) to USB bridge chips overheat and data loss immediately follows. You should either use the interface from a good producer, or glue a big fat heat sink onto the chip, or both.

4. Never remove the card without duly unmounting it. It's usually safe to reboot the computer and pull the card when BIOS screen appears but you cannot be absolutely sure for it.
