How to wipe data from readonly filesystem disk?
The SSD is broken. Mounted only in readonly. Managed to make a backup.
How to erase everything from it? The usual mount / umount tricks do not work, or I'm doing something wrong.
There is no goal to restore - just erase before transferring to the SC.
UPD. Another point that I'm afraid of. The laptop was sold with Windows, and I operated it with Ubuntu. The disk is partitioned accordingly, there are three partitions: UEFI, swap and EXT4 - and this is obviously not for Windows. After all, such operation "for other purposes" can be the basis for refusing warranty repairs?

sudo /sbin/hdparm --security-erase 'NULL' /dev/sd<буква устройства ssd>
Привычные фишки с mount/umount не работают, или я что-то не так делаюесли честно пока не очень понятно что вы делали ))
SSD поломался. Монтируется только в readonly. Удалось снять резервную копию.Это как раз указывает на работоспособность диска. Возможно, испорчена лишь файловая система, из-за чего Убунту может монтировать лишь в режиме чтения.
