Internal hard disk drive not showing in file manager[SOLVED]

#1 Post by cydragon »

Hi,
I just reinstalled Debian 10 on my desktop computer and noticed my internal hard disk drives were not showing on my file manager to be mounted i checked throught the command lsblk which resulted in:

Code: Select all

NAME                       MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINT
sda                          8:0    0 223.6G  0 disk  
├─sda1                       8:1    0   512M  0 part  /boot/efi
├─sda2                       8:2    0   244M  0 part  /boot

  └─sda3_crypt             254:0    0 222.8G  0 crypt 
    ├─dream--pc--vg-root   254:1    0 206.8G  0 lvm   /
    └─dream--pc--vg-swap_1 254:2    0    16G  0 lvm   [SWAP]
sdb                          8:16   0   1.8T  0 disk  
sdc                          8:32   0 931.5G  0 disk

I then checked through blkid which showed:

Code: Select all

/dev/sda1: UUID="4014-B501" TYPE="vfat" PARTUUID="3b71eb5f-39f6-417c-b462-eb39dc39c5a9"

/dev/mapper/dream--pc--vg-swap_1: UUID="f2876d9e-2f7f-4255-9fd1-6553557011de" TYPE="swap
Please keep in mind that sdb and sdc are the drives i am trying to mount, i never really had this issue before during my first time i installed Debian on my desktop, i'm not sure on the case of why this is happening, i checked /etc/fstab and noticed it was missing. I did try to edit it and this is what i have, i obviously did it wrong since i got an error for it:

Code: Select all

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#

PTUUID=10943a0b-6042-4a33-9e93-585e09b0f784 /dev/sdc   ext2     0       0
when doing that i got this error:

Code: Select all

mount: /dev/sdb: special device PTUUID=8a3a40fb-b264-437c-863d-bbc11ee65e34 does not exist.
mount: /dev/sdc: special device PTUUID=10943a0b-6042-4a33-9e93-585e09b0f784 does not exist.
I checked through fsck for the filesystem type before editing /etc/fstab and this is what i originally had:

Code: Select all

fsck -N /dev/sdb
fsck from util-linux 2.33.1
[/usr/sbin/fsck.ext2 (1) -- /dev/sdb] fsck.ext2 /dev/sdb
after editing /etc/fstab and got the errors, i checked it again for both drives:

Code: Select all

fsck -N /dev/sdc
fsck from util-linux 2.33.1
[/usr/sbin/fsck.ext2 (1) -- /dev/sdc] fsck.ext2 PTUUID=10943a0b-6042-4a33-9e93-585e09b0f784

Code: Select all

fsck -N /dev/sdb
fsck from util-linux 2.33.1
[/usr/sbin/fsck.ext2 (1) -- /dev/sdb] fsck.ext2 PTUUID=8a3a40fb-b264-437c-863d-bbc11ee65e34
Overall i do i feel like im doing somthing wrong or may be missing somthing, so any help with this would great, thanks!

edit: nevermind i actually used cfdisk this time and fixed it

here is how i did it:

Code: Select all

cfdisk /dev/sdb

mkfs.ext4 /dev/sdb1

Did the exact same thing for /dev/sdc, now everything is back to normal. I also came across this guide that was helpful too: https://superuser.com/questions/161932/ ... -in-debian

Thanks again! Hopefully this post can help others when have a situation similar to mine. :D

Oh ok, i'll definitely be sure to keep that in mind, i already took care of /etc/fstab before doing cfdisk. Here is what i have currently on it now:

Code: Select all

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

/dev/mapper/dream--pc--vg-swap_1 none            swap    sw              0       0
After editing /etc/fstab, I used cfdisk to mount my other drives. I do appreciate you pointing out what i messed up on though. :)
