[Cannot read ... Reached the end of the file. Help!]

@dbminter Maybe, but EOF is not the same as a slow-responding storage device. There are plenty of devices that are just slow (not least optical drive readers).

Still, worth a try.

[Cannot read ... Reached the end of the file. Help!]

I'm trying to burn a 100 GB M-DISC (BDXL quad layer); I keep getting this error. For sure the file was not open at the time.

FWIW, the source is drive G: which is a Google Drive File stream drive.

But it wrote the first 36 GB just fine, and when I try to read the offending file, I can copy it just fine (tried copying to the desktop).

Advice?? (See screenshot at end of post.)

Here's the log:
