Recover audio corrupt file

I have a m4a audio file that I cannot play. Probably, while it was being saved by the phone, the phone ran out of battery. I have seen using an hex editor that after some moment, all the hex values are 0. I guess that I cannot play it because the player looks for the end of the file and it doesn’t find anything. Still, if I remove all these 0, the file goes from 23 MB to 9MB so I understand I still have some audio stored. Does anybody how to recover this? I tried untrunc but it’s not working. Maybe I should “close” the audio file? Should I write some hex values at the end of the file?

tried installing ubuntu over a corrupt install of windows 7, can’t boot into ubuntu

I wanted to try linux, so I installed Linux Mint over Windows 7 on my laptop. After a while I decided to go back and tried to remove Linux Mint and install Windows 7 again but something went wrong. I couldn’t boot into Windows 7 even though it was there. Then I tried installing Ubuntu in the hopes of an easier way to install Windows 7 again but now I can’t boot into Ubuntu because it keeps bringing up the Windows Boot Manager on boot with 2 seperate instances of Windows 7 to choose from even though I don’t have Windows on this computer. The install option of ubuntu that I chose was erase disk and install thinking that it could give me a clean slate to work in. Anyone got any ideas?

“verify local data” doesn’t fix corrupt download

I can’t specifically say, but I think one particular torrent keeps showing as corrupt. What I’ve done is to locate the specific folder, deleted all of the downloads, and then re-initiated the download.

Yet I keep getting this one specific error, and only for this particular torrent — I think.

Verifying local data has no effect. The file(s) aren’t in use.

Format corrupt sdcard

I have a 32 GB sandisk SD card. I used it for a while in my phone, and I put some music on it. Later I put it in an old samsung phone I had laying around. The old (2006) phone said it needed to format the sd card first. I clicked accept. Now the sdcard became useless.

I have already used the Disks utility. It gives an error (first image)

GParted says “opperation complete” but after It re-scans the drives, it says that the filesystem is unknown again. Even after repeating the proces multiple times in a row. (Second image)

The computer does recognize the size of the sdcard though.

Anyone with more ideas as to how to make this sd card useable again?!

You can see the 2GB tag in the background of the disks image, that is another drive, not the one with the issue

K3B burn verify fails; error reading sector; Resulting DVD either unreadable or corrupt. Please help

Please help with the following K3B burn problem. Recently I have been trying to write .iso images as a data project to DVD using K3b but the DVDs often end up corrupt or unreadable.

The burn session always comes out successful but the read verification seems to fail every other time I create a DVD. The error says something like:

“Error reading sector…” and whatever number etc.

When testing DVDs that fail the verification, it usually turns out that the last track on the disc can’t be copied to the desktop and results in an error message like:

“Error splicing file input/output” or something like that.

Unfortunately, I couldn’t find any answers online and I would like to avoid wasting time and DVDs every other time I burn a DVD. I don’t know how to stop these corrupt burns from happening in the future. Any help to resolve this issue would be appreciated. Thank you.
