I am getting a -101 or -105 error when trying to restore a project Archive, or glitches in movies when using an external usb-c drive
We have uncovered an iOS issue where on some external drives, files can become corrupted (we believe this only happens with drives or partitions larger than 128GB). We are in contact with Apple about this issue and hope it will be resolved in a future iOS update. In the meantime, unless you reformat the drive as shown below, do not save project archives or movies to external drives connected to your iPad (this issue does not affect wireless connected drives like GNARBOX or WD Wireless Pro).
Project archives that currently report a -101 or -105 error may be unrecoverable, but please contact firstname.lastname@example.org and we'll do our best to recover the archive for you.
You can avoid this issue by reformatting your external drive to use APFS format rather than the more common ExFAT that most drives are initially formatted with. You should only use this format if you're using the drive on macOS and iOS systems (if you need to access the data on Windows, then you must continue to use ExFAT, and should not store any project archives or fcpxml archives to the external drive).
To Format Your External Drive as APFS
- Connect your drive to your Mac
- Backup any of the contents of the drive to a folder on your Mac's internal hard drive (using Finder, drag-and-drop all of the files and folders from your external drive to a folder on your internal drive)
- Tap on the search button in the top menu bar, and type disk utility then press enter to start the Disk Utility
- In the Disk Utility, select the View button at the top-left, and check Show All Devices
- Select the physical hard drive from the list on the left (when selected it should say USB External Physical Disk under the name in the main window)
- Select Erase from the tools along the top, then select APFS from the Format dropdown (and make sure GUID Partition Map is selected for the Scheme), then click the Erase button.
- Once the process completes, you can copy any backed-up files to the external drive, then eject the external drive and begin use on iOS.
