HDDRAY

The small Python code that try to repair slow (and bad) sectors by different methods!

The new HDDRAY v.16.8.6 version!

Info about this version:

• Code was made by Copilot instead ChatGPT
• Features like "repair" mode working now fine with big LBAs
• Fixed "max_latency" isuue: code did not recognize hangs

Todo: the todo list only applies to the latest version, on which the work is being done, for the release see the info provided by the release itself

• Harddrive locking (sometimes there are errors due to this problem)
• Better error handling
• Autocreation of settings.ini (if missing)
• Full test of all functions on very big sizes of drives (need a physical bad drive)
• Compatibility for UNIX systems
• Faster analysis of the sectors (by reading couple of sectors at once instead one-by-one)
• Better UI
• Help page inside the code
• Wiki page on GitHub
• Automatic elevation to administrator privileges at startup
• Handling of insufficient space left in the code place (system just can't write anything to the list of recovered sectors.txt because drive was full)

About

HDDRAY have 4 modes:

• repair
• workout
• f1
• regenerator

All this modes have different behavior when a bad sector is found or when the sector response time does not meet the specified limits

Repair mode:

• read sector
• if access time exceeded: rewrite the sector x times, go to the next sector
• if read error occures: rewrite the sector x times, go to the next sector
• if no errors occured and latency doesn't exceed specified limits, go to the next sector

Workout mode:

• works only after running any other mode
• reads listed sectors from list of recovered sectors.txt and "trains" this sectors
• optionally bad sectors can be "trained" (usually this will not restore this sector, but you can try)
• unstable sectors will be "trained" and if successed - listed as "good/healthy"

F1 mode:

• write specific pattern x times, then read it
• if pattern match, go to the next sector
• if read error occured or pattern didn't match - repair it
• [please add more details]

Regenerator mode:

• works just like repair mode but have other repair settings
• [I forgot what it do]
• [need to rewrite the code]
