Dying laptop problem

Post by chhejr » Sat Oct 12, 2019 2:59 pm

I have an old Acer Aspire v5-131 series laptop that isn't booting all of a sudden. I've had linux mint on it for years without problems, but today when I typed in my password on the login screen it froze. I held down the power button to force a reboot, and when I reboot the system it just showed a black screen forever. Then I held the power button again to force a reboot and this time it boot to the Acer display screen like its supposed to, but then it displayed a black screen for a very long time until finally showing an error message reading:

"error: failure reading sector 0x802 from 'hd0'
Entering rescue mode...
grub rescue>_"

All I want to do is get the files I have saved on my desktop, nothing more. I don't care about saving the laptop. How do I do this. I have an All in 1 HDD Docking gizmo Model:875 which is compatable with all 2.5" or 3.5" IDE/SATA HDD. I'm not sure if I can use this in some way to get these files off, if some computer repair store could fix this, if I need to send the hard drive to some expensive recovery service, or if someone on this forum knows some way in which I can pull my data off easily with a flash drive or boot to the OS in some way. Desperate, please help.

No guarantee, but I'd try booting a live USB of current Mint and see if the laptop hard drive can be mounted in the file manager - files could be transferred to an external drive for safekeeping. Unfortunately there may be permissions issues with the hard drive, depending on configuration. Less likely, but no harm no foul, Mint 19.x has Boot Repair preinstalled, it can be run from a live USB install and is a simple GRUB repair interface that might solve the laptop's new boot issue.

I haven't needed it in years, but never had to go past the one-cllick Recommended Repair in the past.

Live session would be the simplest way. Sounds like the drive is still spinning but damaged per "error: failure reading sector 0x802 from 'hd0' message.

So I am a little confused. How do I mount the drive when I us a live cd? Do I have to physically remove the hard drive from the computer and connect it with a USB wire? Or do I not need to remove it and it will just automatically show up on the file system (And if so where)?

Boot from a live CD/USB and you will see the laptop drive in your file manager once in the live environment. Click on the drive and it will mount. Copy any data you want to an external you would also have plugged in via USB.

I just booted my system in a live cd. I then opened the file manager and it listed my hard drive (459 GB) and another device (767 MB) which I am assuming is the live cd itself. I clicked the hard drive (459 GB) to mount it and it asked for my password. I entered my password and I got the following error message:

Unable to mount 495 GB Volume
Error mounting /dev/dm-1 at /media/mint/fdeea28a-46d4-469c-a551-f452e5566ef2: can't read superblock on /dev/mapper/mint--vg-root

Is that drive or partition encrypted, by any stretch of a wild imagination?

That's the "permissions" issue I referred to (or the hard drive is mechanically defective). The laptop drive is being treated as "external" and I'm not personally aware of a way to access it from the live USB without booting the laptop itself and resetting the drive's permissions as an administrator. Running Boot Repair from the live USB to try to fix GRUB on the laptop may be worth a shot. Someone else may know better. It might come down to professional data recovery if the material on the drive is important. (File back ups are the best preventive, shame if it wasn't done.)

Yes, the drive was encrypted during the linux mint installation.

I am using linux mint 19.1 live cd, but I don't see boot repair listed when I type it into the program search. How do I access it and how do I use it for this situation? Secondly, if I hire a professional recovery service, is there a reasonable chance they can get my files considering this situation?

Ok, you have three basic choices. Kiss your data goodbye or restore from backup. The other choice is less likely to be successful, but you can continue to search for a solution, but I don't hold out hope.

Really, drive encryption has no valid use case in any domestic situation, irrespective of the OS, and people shouldn't use it unless they are fully prepared for complete and utter data loss. Professional data recovery is not likely to help here.

For future reference, if you really do need to keep some things private, use VeraCrypt and set up secure containers, which can be copied and backed up.

Do you know the partition on which you have Mint? Was /home on a different partition?
Have you set up logical volumes while installing?
See and try

I don't know the answer to all of those questions. When I installed linux mint I just used whatever default partitions it chose. I don't remember what that was. I just typed fdisk -l in the terminal and it says that there is /dev/sda1 which is 731M and there is /dev/sda2 which is 465G extended and there is /dev/sda5 which is 465G linux.

When I typed into the terminal the command sudo badblocks -v /dev/sda5 > badsectors.txt it just looks like it hangs. It outputs checking blocks 0 to 487634943 checking for bad blocks (read-only test): and then it just hangs there doing nothing else, cursor just blinking.

Let it run for a while.

Still not doing anything, just blinking cursor. Does professional data recovery have a shot of working?

A very good chance that the forum will be anle to solve it. There are Linux professioanls available here. Did you try the link? The bad block can be mapped and the good drive can be retreived. But I dont know how to handle encryption.

Ok, the terminal command "sudo badblocks -v /dev/sda5 > badsectors.txt" just finished. It gave the output "done Pass completed, 0 bad blocks found. (0/0/0 errors)". What does this all mean? How can there be no bad blocks found if the hard drive isn't working? What should I do next?

Try the smartmontools as given in later part of the article.If it gives any errors post them here.From sda1 to sda5.

Similarly try badblocks for sda1 to sda5. Did fdisk list sda1 to sda5?
