Hey guys,

I've been trying to encode a BluRay of Jurassic Park, but I keep getting this Posix error. The disc looks flawless, so I'm not sure what's going on. Any help?

Internal or external drive?

A number of external drives have issues with power if you spin them at full speed, which few applications can. MakeMKV is one that can, so drives fail during rips. The errors in the log imply that the drive went off-line during a long read (about 24GB into the title), which is where it would be reaching maximum speed.
