Strange problem. Last night I was using plan mode to take 240 subs of LDN1622. ASIAir plus, 533MCpro. 1 minute subs. Using a 128GB USB drive. When I plugged the drive into my computer there was one corrupted file at #30. No other file was there after that. The strange thing is that if I plug the drive into the AIR and access it from my IPad all 240 files are still there including the corrupted file#30. So I was able to delete the corrupted file while on my IPad hoping that when I plugged it back into my PC the missing files would show up. But they still didn't. I then thought to plug the air into my PC via a USBc to USBa cable. But then it only accesses the internal drive and not the plugged in USB drive. Anyone know why. I can see the files while the drive is plugged into the Air on my IPad but not when the drive is plugged into the PC? Is there a way to copy the files directly from the USB drive to the internal storage while it's plugged into the AIR? I did 2 more targets after and they both did fine.
