Mount error special device /dev/sda1 does not exist
location: ubuntuforums.com - date: July 7, 2014
I am trying to recover some data from a ext4 file system. Just to give a bit of a background i was using Ubuntu 12.04 since last 6 months. Recently i had done a R update and after the next restart i am not being able to boot the machine at all.
For more details please refer to my original thread http://askubuntu.com/questions/49209...-12-04lts?lq=1.
Right now i am trying to recover my data using a live usb of 13.04. I have got some of my data back but i still can't access the /dev/sda1 which had most of my data. The partition is showing in gparted as well as sudo fdisk -l.
Sudo fdisk -l output:
Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors

Mount encrypted, LVM volumes without "special device... does not exist" error
location: ubuntuforums.com - date: June 8, 2015
My attempt at rescue of encrypted disk was stalled by the following error, which occured when I tried to mount my encrypted LVM volumes:
mount: special device /dev/hd... does not exist
This error occured while following the excellent instructions given by jerome1232 in this SOLVED thread here: http://ubuntuforums.org/showthread.php?t=940904
This seems to be a common problem.
Forums widely report that the solution is to use the following command to make the logical volumes active:
sudo vgchange -a y Ubuntu
But there are unsolved requests for help where this command is used and the VGs are activated and yet the same error occurs: "mount: special device... does not exist".
The problem is the mount command, e.g. to mount the logical volume called "home" to the mount point at "/media/home":
sudo mount /dev/Ubuntu/home /media/home
It seems to satisfy some people. But, for some unexplained reason, it may not work as given.

Problem booting Jolicloud Alert! /dev/hda2 does not exist! Dropping to a shell!
- date: December 23, 2010
I just installed Jolicloud alongside Windows. When I try and boot I get this error:
Alert! /dev/hda2 does not exist! Dropping to a shell!
BusyBox v1.13.3 (Ubuntu 1:1.13.3-1ubuntu11) built in shell (ash)
Enter 'help' for a list of built-in commands.
I can boot the same os off a USB stick and get to a terminal, where I have managed to mount the root.disk container file.
grub.cfg has an entry
linux /boot/vmlinuz-18.104.22.168-1-jolicloud-atom root=/dev/hda2 loop=/jolicloud/disks/root.disk ro quiet splash
I suspect that is the issue, how do I work out what should be in the root = line?
This is the output of blkid:

“ALERT /dev/sda1 does not exist dropping to shell” after Ubuntu 10.10 install reboot
location: ubuntuforums.com - date: March 28, 2011
Hi. I am attempting to install Ubuntu 10.10 desktop on a Dell T7500 with two SAS drives in hardware RAID 0. Running from the CD works fine. The install process works fine. I have configured several different filesystems for /, /usr, /home, etc. The problem is that upon reboot after install, during initrd the system complains "ALERT /dev/sda1 does not exist dropping to shell". From within the initramfs shell I am able to mount all partitions successfully. Can anyone tell me what might be wrong or how to diagnose this?
