System booting/running awfully slow

@iansixx

what i actually need is to diagnose the state of the drive.

Multiple READ DMA EXT errors on your drive, but all were at the same time (so probably the power loss)

@iansixx

no important files are on the drive,

@iansixx

  ID-1: / raw-size: 257.76 GiB size: 252.65 GiB (98.02%) 
  used: 203.77 GiB (80.7%) fs: ext4 dev: /dev/sda3 maj-min: 8:3 label: N/A 
  uuid: 5222c916-df1a-4521-a528-7f3095a0d71a 

I beg to differ: your OS on this drive!

So do the following:

• Take a full Cold system backup using a CloneZilla Live USB to an external drive.

• download, burn and Boot a Manjaro USB stick

• Go to KDE partition Manager,

• write down all partitions as they are

• Write a new GPT partition table on that disk

• Create the exact same partition(s) as before

• Write zeroes to all the new partitions

  cat /dev/zero /dev/XdYN
  

  where X, Y and N denominate your partition names
  Why, oh why: this is taking so long!
  You still have 59 spare sectors:

  @iansixx

    5 Reallocated_Sector_Ct   0x0033   059   059   036    Pre-fail  Always       -       1693
  

  and the cat will ensure that all sectors in the disk are written to so that the disk can swap out any bad sectors with the spare ones (36 have been used already)

• Boot the CloneZilla Live USB again

• Restore your Cold System backup
