Sorry, until someone steps in with better ideas, I can only toss out one more thing to look at, I am not expert in this at all. Btw, is your system a UEFI+GPT, or the older BIOS+MBR?

You might look at gdisk if you have a GPT. I messed with this a little bit, and for my small set of experiments concluded this:

Summary
For a UEFI+GPT setup, if you damaged your GPT structure, or if you accidentally lost/damaged your partitions, you may be able to use TestDisk and gdisk to recover. One goal here is to see how TestDisk worked on GPT. Good news: It recovers deleted partitions. But: I could not use TestDisk to repair either the Partition Header or the Partition Table entries. For those two tasks, I used gdisk. I did five experiments. There are references included along the way for everything. (If you can use TestDisk to fix the damage described in experiments 4 & 5, let us know.)

And if a drive is a GPT, you might run
sudo gdisk -l /dev/sdx
to see what it says (where, of course, sdx = sda, or sdb, etc.).
If a drive is not GPT, you might try
sudo fdisk -l /dev/sdx
-- again, just to see what comes up, any clues, and such.

Sorry to say, but I think this hdd is almost dead. If your computer will start without the hdd plugged in , that would confirm it. Get what you can off of it and see if you have any other drives to use in it. If you can get about $210, you can get a 500Gb ssd from amazon. Less for a standard hdd, but not as fast

Thanks all! Here's an update:

I have a liveCD of Kubuntu running, and I ran

Code:

Sudo fdisk -l /dev/sdb

And this is what was returned:

Code:

kubuntu@kubuntu:~$ sudo fdisk -l /dev/sdb Note: sector size is 4096 (not 512)

I'm assuming that the disk is GPT.

Apt will not let me install gdisk, and returns the error:

I'm going to try to work on that. Any tips from here are still appreciated!

If you want to change it from GPT to msdos and don't have any important data on it, get a livecd of gparted and use it to create a new partition table. Be warned

, doing so will erase everything off the drive, but it may help if the partition tables are both shot. GPT saves one at the beginning and one at the end of the drive.

**technomancer** · Jul 21, 2015, 08:30 AM

Sure thing, will do. In the meantime, I already ran gdisk and was greeted with this:

Code:

kubuntu@kubuntu:~$ sudo gdisk -l /dev/sdbGPT fdisk (gdisk) version 0.8.7


Partition table scan:
  MBR: protective
  BSD: not present
  APM: not present
  GPT: not present


Creating new GPT entries.
Disk /dev/sdb: 122096646 sectors, 465.8 GiB
Logical sector size: 4096 bytes
Disk identifier (GUID): 9563EA2A-9C52-4904-9783-3D90E9E7EC48
Partition table holds up to 128 entries
First usable sector is 6, last usable sector is 122096640
Partitions will be aligned on 256-sector boundaries
Total free space is 122096635 sectors (465.8 GiB)


Number  Start (sector)    End (sector)  Size       Code  Name

Does that help us at all?

I'll get back to you with the scans. Thanks, TM

Thanks for the update. I really don't want to erase everything of I don't have too. Would it hurt the disk to recover the table, a supposed to re-writing it?

Responding to Post #9.

So you have Kubuntu 13.10.

gdisk says you do NOT have a GPT--that's OK for now. Leave it that way because we don't want to mess with too many changes and variables.

SMART may tell you if there's some fundamental problem with the HDD.

I'm guessing your computer is using the older, standard BIOS and MBR to boot. It doesn't seem to be using the newer UEFI. And that is OK. Just noting the fact. (/usr/lib/grub would tell you about this: if all you see is grub-pc, then you are booting BIOS+MBR; if you see anything like grubx64.efi[-signed], then you probably have UEFI. Sounds like your system is a bit older, like maybe before 2011 or so => BIOS+MBR, probably)

We are hoping that SMART will tell a story here about the health of the HDD in question ...

**Qqmike** · Jul 21, 2015, 08:45 AM

If you use TestDisk to recover/fix the partition(s) and/or the partition table, it should not destroy anything of your data ... BUT, holy cow! This is the most major surgery you can imagine doing on your system ... I would definitely back up all my personal data (documents, photos, vids, whatever). gdisk works on GPT, and it will convert your MBR to GPT, but I don't think I'd take that step at this time. I'd hold the line and try to find out what caused this change in your system and try to fix it "as is." And someone else on the forum may be able to chime in here with something more definitive.

First: SMART, see what it tells you about the health of your drive(s).

**Qqmike** · Jul 21, 2015, 08:58 AM

Going back to your first post.
It's your sdb showing the problems:
Bad relative sector
Bad GPT partition, Invalid Signature

But then gdisk shows no GPT present.

Looks like you have a GPT on sdb, but it is damaged in a way that makes it seem like non-GPT to gdisk?

If, in fact, it is GPT on sdb, gdisk should be able to fix the GPT (the partition table) and fix partitions.

EDIT:

And gdisk isn't showing any partitions on sdb, do I read your output right?

Where is your Linux, on this sdb? (and your Windows is on sda?)

Upon refreshing the page after posting this, I read several posts that do in fact tell me what I'm doing. Thank you all!

Kubuntu 13.10 is the LiveCD I'm using. My hard drive dual boots Windows 8 and Kubuntu 15.04.

I remember having a heck of a time installing Kubuntu side-by-side with Windows 8, because 8 uses UEFI, and that screws it up somehow. What I do know is, when I start my computer, I'm taken to a GRUB menu. From there I can pick windows 8 if I wanted to.

Does that help us?
