ata_id_major_version(9)

🎀 ata_id_major_version(9) 🎀

okay so this page is from the Kernel API Manual, and it's literally all about getting the ATA level of a drive. bestie, it's giving “tiny function, big caveats” energy 💅✨

✨ NAME ✨

ata_id_major_version — get ATA level of drive 🦋

🌸 SYNOPSIS 🌸

unsigned int ata_id_major_version (const u16 *id );

🦋 ARGUMENTS 🦋

• id — Identify data. that's the pointer you hand over, no cap 💖

💖 DESCRIPTION 💖

Okay so the caveats are the main character here, and you gotta know them:

• ATA-1 considers identify optional
• ATA-2 introduces mandatory identify
• ATA-3 introduces word 80 and accurate reporting

The practical impact of this is that ata_id_major_version cannot reliably report on drives below ATA3. like, fr fr, below ATA3 it's not giving reliable info 😭

🔥 RETURN 🔥

major version of ATA drive level, or 0 if unknown. periodt 💅
