//

// D8 range boundaries are shifted left by 150 sectors comparing to BE
//
// It is also possible to read large negative offset ranges (starting from 0xFFFFFFFF - smallest negative 32-bit integer)
// with BE command with disabled C2 if the disc first track is a data track. Regardless of a starting point, such reads
// are "virtualized" by Plextor drive and will always start somewhere in the lead-in toc area and sequentially read until
// the end of the data track under normal circumstances. After some point, the drive will wrap around and start in
// the lead-in toc area again. This process will continue until drive reaches firmware blocked LBA ranges specified here.
// However, any external pause between sequential reads (Debugger pause, sleep() call etc.) will lead to drive counter
// resetting and starting reading in the lead-in toc area again.
//
// However the following range, while preserving the above behavior, is unlocked for both BE and D8 commands with
// disabled C2. Use it to dynamically find first second of pre-gap based on the Q subcode and prepend it to the rest of
