nvme_write_uncorrectable(2)

✨ nvme_write_uncorrectable ✨

okay bestie, welcome to the libnvme API manual 💖 we're doing the nvme_write_uncorrectable(2) page today and honestly? it's giving chaos goblin energy in the best way. pull up a chair 🫶

---

🌸 NAME 🌸

nvme_write_uncorrectable — submit an nvme write uncorrectable command 💅

---

🎀 SYNOPSIS 🎀

int nvme_write_uncorrectable (struct nvme_io_args *args );

---

🦋 ARGUMENTS 🦋

• args — the struct nvme_io_args argument structure, bestie. that's the little bundle of info you're handing over so the command knows what it's doing ✨

---

💜 DESCRIPTION 💜

so. the Write Uncorrectable command marks a range of logical blocks as invalid. that's it, that's the whole job. it's literally pointing at blocks and going "these ones? yeah, they're done, don't trust them" 😭

and then the iconic part: when you read those specified logical block(s) after this operation, a failure gets returned, with Unrecovered Read Error status. no cap. so any read of them just goes 💀

ngl if you want to clear the invalid logical block status, you're gonna need to do an actual write operation on those logical blocks. that's the price of admission, periodt. no shortcut, no magic undo button 🧚

---

⭐ RETURN ⭐

it hands you back the nvme command status if a response was received — peep enum nvme_status_field for that iykyk 👀

or, if not, it's -1 with errno set. classic. 🙈

---

lowkey important: this one doesn't just delete stuff, it makes the blocks unreadable by design. so like, know what you're doing before you point it at a range, bestie 🫶

---

and that's the whole page, you ate that 💅✨

signing off from the libnvme API manual era, dated July 2026 — stay iconic, go read your blocks responsibly 👑💖🦋🌸🎀
