• Reread LBA 0 because apparently there are values of 'read' buff that can actually alter the cache too! Yay!

• Fix bug when no 3C values were found before using the 3C memory dumper.

• Have the drive reread LBA 0 each iteration of F1 bruteforcing to see if I can prevent F1 from modifying data already on the cache.
• Change compression from .zip to .7z for better compression ratios.
• Add cleanup function to clear duplicate files.
• Print file hash (SHA256) for every file in the log.

• Fix bug with interrupt handlers so that contents of the discovered values array are retained after getting out of the function.
• Potentially fixed a bug where drives that don't rotate back to the beginning of memory when the offset is set too high and thus don't create the files for the memory dump occurs. I couldn't test this personally but I know someone tested a drive that this occurred.
• Moved mem_dump_3c to before bruteforcing f1 just in case bruteforcing f1 writes to cache.
• Reread lba 0 after f1 bruteforcing but before testing other commands just in case bruteforcing f1 wrote to the cache.

(TODO: Finish testing 7z support, look into adding a general cleanup function to clear duplicate files.)

• Add interrupt handlers (CTRL+C) for scanning 3c/f1 values just in case drives hang or take too long.
• Added an experimental RAM dumper. This will take the first 3C opcode discovered that returned valid sector data with a valid PSN. This will try to dump 16MB with the command, which should be close to the start of DRAM. This process can also be interrupted with Ctrl+C. Note, how drives handle CDBs with invalid offsets is up to the drives I think. For my PX-716A, it didn't complain when I used a high offset value. Commonly, it should 'loop around' to the start of DRAM if the offset is beyond the size of available RAM but it might be up to the firmware so expect something to happen if they dont.
• Small spelling mistake changes.
• 3C bruteforce values are now stored in an array so that they can have some applicable use.

• Fix typo for READ LONG
• Fixed assumption that the PSN was 4 bytes long rather than 3. Adjusted the script so that it treats the PSN as 3 bytes.
• Add sector id description (which is the first byte in the sector)
• Pretty up the log a little.
• Update sg_raw to the latest version.
• Dump PFI/DMI/BCI/etc from the disc (todo, decode the information and dump it raw using the found commands).

2023-10-01a

• Add a condition for when timeouts occur by using a temp file. To prevent the drive from resetting, potentially causing cache to be cleared, reread LBA 0 if the drive was suspected to have been restarted from a time out.
• Save LBA 0's 2048 byte user data into a binary file for analysis.

2023-10-01

• Add a timeout of 20 seconds for sg_raw.exe calls in case they take too long to return data for that value.
• Fix a copy pasta error for the progress bar for F1 bruteforcing (was meant to cover 256 possible values, was showing a bar for 256 * 256 possible values)

2023-09-30

Adds progress bars for 3c and f1 bruteforcing.
