[Solved] Cant delete partion or flag

Post by silvatech » Mon Jun 18, 2018 5:58 pm

This is really strange. I have an SSD and a regular HD I partition at the same time. Partitions on the HD are performing as expected. The partition on the SSD wont give me the options to flag it and I cant delete the partition either!!! I have tried doing this through my current mint OS as well as booting up mint off of a flash drive and I get the same issue. Any clue what would cause this?

edit

if I run in terminal I get this odd error.

sudo fdisk /dev/sdb

Welcome to fdisk (util-linux 2.27.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

/dev/sdb: device contains a valid 'ext4' signature; it is strongly recommended to wipe the device with wipefs(8) if this is unexpected, in order to avoid possible collisions

Device does not contain a recognized partition table.
Created a new DOS disklabel with disk identifier 0x0dc06af8.

Really strange even though it was showing a partition in gnome part as well as disk part. It was not showing in fdisk. Creating it through fdisk seem to correct the issue go figure!

"...dev/sdb: device contains a valid 'ext4' signature..." Somehow you managed to make a "Super Floppy". That's when the first sector of a file system is on the first sector of a drive -----> no partition table -----> gparted can't edit a partition record that simply isn't there. Neither can fdisk, but you get a better hint that there's something funny going on.

If you know you are going to wipe the drive anyway, manually writing zeroes to the first few megabytes will clear nearly everything partition-related without the delay of a full secure-erase. It doesn't necessarily wipe RAID signatures or GPT backup tables, which get put at the other end of the drive, in case of accidents.
Data stored in an encrypted volume will only be accessible with the original password. Without this key, all the data will remain scrambled beyond hope of recovery.
