LIBNVME_NS_WRITE_UNCORRECTABLE-LIBNVME3(2)

💅 libnvme_ns_write_uncorrectable — the "write uncorrectable" command, explained

okay so bestie, real talk: this one lives in the libnvme API manual, section 9. the page header up top literally reads libnvme_ns_w...ncorrectable(9) (yes it's truncated like that, that's just how it prints, don't @ me). anyway. let's get into it ✨

🦋 NAME

libnvme_ns_write_uncorrectable — issues a 'write uncorrectable' command

like. that's the whole vibe. it writes stuff that the drive is then gonna consider uncorrectable. iconic behavior, honestly 💅

---

🎀 SYNOPSIS

, size_t count );

copy it exactly like that, no cap, the line break and everything 🫶

🌸 ARGUMENTS

• n — your namespace instance. the whole main character here 👑
• offset — the LBA offset in n. so like, where in the namespace you're starting 🎯
• count — how many sectors are getting written. the number of them. the sector count. you get it 💖

Number of sectors written 🔥

that's it, that's the return value. count your sectors, bestie.

ngl this page is short and I'm obsessed with it for that. no filler, just facts 🙈

🧚 sign-off

this lil gem was hanging out in the libnvme API manual in October 2026 — that's the date and the source/version stamped on the footer, October 2026 and libnvme_ns_write_uncorrelibnvme_ns_w...ncorrectable(9) (the footer truncates the name too, we don't make the rules 🫠). k bye, go write some uncorrectables responsibly 💜🌈
