Ubuntu :: Recovering Corrupted JPEGs On SD Card?
Oct 12, 2010
I needed to use an SD card for something unusual today, but wanted to preserve all the photos on it. So I unmounted it and ran...
$ sudo dd if=/dev/mmcblk0 of=/home/kip/Desktop/Camera.bin bs=1MB
...to make a backup of the complete card, partitions included. I used the card for other purposes, umounted again, and then wrote back the image with...
$ sudo dd if=/home/kip/Desktop/Camera.bin of=/dev/mmcblk0 bs=1MB
I unmounted, removed the card, and then re-inserted to find most of the JPEGs corrupted. I can see some pixels, but they are all mangled.
I fear the blocksize (bs=1MB) may have been the culprit and should have been 512 (bytes) for a card containing a fat16 formatted partition.

I've just tried installing drivers for my laptop (sis 671) and now my desktop gfx are corrupt. Any idea how I can recover? (eg delete xorg.conf).Recovery mode is corrupted, command prompt boot is really limited and I can't figure it out.

I recently suffered a hard disk failure, meaning I had to replace the faulty device. After attempting to mount the old faulty hard drive using and external caddy, I got the following message... Unable to mount 144 GB Filesystem Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdb5, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so
I'd like to attempt to recover what I can from my /home directory but unfortunately I use encryption (although I do actually know my pass phrase). What procedures and software can I use to try and recover data from this drive?

In the last week I have been noticing sound issues. Today my sound stopped working all together. I have a dual boot system: Windows XP and Ubuntu 8.10. The sound works fine under XP. My understanding is that there are problems with PulseAudio. Ive checked all the obvious things such as "mute" etc. My guess would be a corrupted sound card driver, but im not sure of the best way to remove it and reinstall it.

I use Nautilus 2.32.0; in Ubuntu 9.10 (I don't remember which version of Nautilus I had), I could select jpeg files, right-click and resize the files; that option is not present now.

Generally on my system(Karmic x64), if I generate a pdf, any image included comes out distinctly blurry. I have googled and come across this [URL] which says when there is a pdf generation, everything is recompressed, hence the blurriness. How is there a way around this? What do I tweak to ensure pictures are left alone (I already ensure they are as small as possible) when I convert anything to pdf?

One of the most common qs i see in forums is >>> How to convert multiple jpg files to one one pdf file by one click . I have got 2 solutions that I consider solve this situation to the best ....
*1.* Install SCRIBUS from synaptic package manager . It can convert jpegs to pdf without any issues . F Spot Photo Manager can also be used .
*2.* This 2nd step I find much better ....
I have been using it myself for some time now ... and its flaw less ...
A) Install WINE using the terminal . For beginers .... Its a software that can run selected windows applications on a linux destro like ubuntu. Installing is very easy >>>> open synaptic manager and in quick search box type Wine. Once the wine files show in the search mark them for installation. For details on easy manual for wine installation check here .. [URL]
B) Now go to the page below .... Its a free software.
[URL]
Down load and save the software from the link given . Open the file using wine ( Right click on the file and choose the option open with wine.) The installer will run and the programme will be installed . And Viola ... Its ready .... Import ur jpg files and merge them all in to 1 pdf file .. Very Useful In Merging Comics together.

My 1st and only grandson turned 1 year old and we have taken about 1 million pics of him. I wanted to make a video from pictures taken in the past year. The first one is an ultra sound picture. The last one was taken this last Saturday. I have 153 12 MPixel pictures in a folder. They are named C001.jpg - C153.jpg (I can rename them if needed).
I had noticed mencoder or ffmpeg can create movies from jpegs. But, I didn't think about the frames per second. Would I need to make like 20 copies of each picture and then make it like 10 FPS? or something like that? Optimally, I would like to have a video where each picture lasts for 8-10 seconds or so and I would be able to add a song as audio. (I think I know how to use mencoder to add the audio).

Is there a way to take a whole directory of pictures that are of various dimensions and scale them all down to conform to, say, an 800x600 (or 600x800) boundary?
Better yet is it possible to also ignore and not size-up files that are, say, 400x300?
I am command line savvy so if it can be done via some kind of script I'm cool with that.

In the Windows world where I came from, Irfanview freeware easily renamed a large folder of JPEG photos by EXIF time & date stamps, appending a unique number if the time and date stamps were the same. Is there an equivalent rename-by-EXIF information batch command in Ubuntu 10.04 Lucid? For example, change (based solely on EXIF information): FROM:DSC_0001.JPG TO:20110224_09:34:56am.JPG

So I have a bunch of directories:
dir1
dir2
dir3
etc.
which themselves all contain subdirectories:
dir1subdir1subdir2etc.and at the lowest level they contain all of these jpegs that I need. The problem is that I only need some of them. They're named like this:
pic1.jpg
pic1_med.jpg
pic1_small.jpg
pic2.jpg
pic2_med.jpg
etc.
I want to just grab the ones without the size suffix and copy them all to another set of folders, while preserving the directory structure. The numbering all starts at 1 for each low level subdirectory, so I think that the directory structure is the only way to not get them mixed up.
I know that cp has a recursive option -r but how do I just extract the ones without the underscore? And then how do I preserve the directory structure when I move them over?

While trying to create a bootable SD to install Ubuntu on a netbook, I accidentally formatted a part of a removable HDD that was connected to my computer. If I remember correctly, the partition I formatted wasn't the main partition of the HDD. In that case, does it make sense that the whole disk was wiped out? On that HDD there's a year worth of work, I really need that back.
I was using PhotoRec with some luck: it started to recover files, but with no names, which is almost useless, considering a lot of it are recordings - useless without their names. Is there any good recovery program that will recover all my files incl. names? Is there a easier oprtion, considering that I think I didn't really format the big partition of the HDD? What may it have been, the small partition?

I installed Ubuntu 9.10 on a 100 GB partition of my 120 GB hard disk. I left the other 20 GB as free space. I moved my data (about 20 GB) to my home folder. Everything was fine for two days. Then I installed a few packages with the help of Update Manager.he installation, I was asked to reboot. Upon reboot, I was always taken to the Memtest86+. It was as if GRUB wasn't detecting my ubuntu installation.Then I installed Ubuntu again by taking up 20 GB of the existing 100GB partition. I am currently using this installation. When I try to access the older installation (the 80 GB one), I find that all my data in my home folder is broken. (screenshot attached - homefolderbroken.png). homefolderbroken.jpgWhen I see the properties of the 80GB partition, I can find my data is still present (screenshot attached - data.png

I've been using Evolution for several years no without problem. Yesterday I started getting the message"Error while openinghome/name/.evolution/mail/local#inbox".The mail is all there in local/inbox.sbd, but I can't find any way to tell the program this. I've got it all backed up on Dropbox, but can't find any trace of a #inbox. At least nothing with that name that's been recently deleted.Is there some way of recreating or recovering the file I need?

So I've pulled two hard drives out of my busted windows xp system (dead mb) and I'm trying to get some data off of them. The drives are in raid 0, so my friend told me that I might be able to do something if I use linux. Some late night searching on the internet directed me to a few resources, one of which was this forum. I've tried 2 methods, neither of which have worked.
1. mdadm
ubuntu@ubuntu:~$ sudo mdadm --detail /dev/sdb
mdadm: /dev/sdb does not appear to be an md device
2. dmraid
ubuntu@ubuntu:~$ sudo dmraid -s
/dev/sdb: "sil" and "hpt45x" formats discovered (using hpt45x)!
ERROR: sil: wrong # of devices in RAID set "sil_agafdhcebccj" [1/2] on /dev/sda
ERROR: removing inconsistent RAID set "sil_agafdhcebccj"
[code]....
I've got some files for work that I'd really like to get off there. I've played with unix a bit in college and I've ran ubuntu before, but usually using the GUI, so a lot of this stuff is over my head. But from what I gather, my system thinks that one of the drives isn't a raid drive?

A friend had a 320 gig hdd he wanted me to back up. I saved all the files in a folder "Documents & Settings" and even made a 7z archive out of it. I used a 1tb mybook and copied the files to it then tried to delete it. Now i had recovered the files using ubuntu, but moved them to my windows partition. When i got on windows 7 and tried to delete the directory "documents & settings" i got an error saying some files had names that were too large or something like that. So i went on ubuntu and deleted the files from my windows partition without moving them to the ubuntu partition.
Well my 1tb drive just broke so i lost the files on there. Now im trying to back the files up using ubuntu. I am running scalpel at the moment, and it hasnt found anything at all. I really dont know if i set up the configuration file right. I just started scanning my other hdd that contains the linux boot. It has just started so i am not sure if it will find anything or not.
But incase it doesnt, how do i set up the config file to find the file? There are two things i deleted off of my windows partition. a 7z file archive which was the 9GB directory "Documents and Settings" zipped, and the actual folder Documents and Settings.

My powerbook died (motherboard or something...). I took out the Hard Drive to mount in an external enclosure. I tried accessing the drive in both windows and mac - no luck. So, I thought I'd try it in Ubuntu, thinking maybe it would show up - no luck. My question: is there any way to access the files from my drive using linux? Is there any way to mount it? The drive is spinning, and when I enter sudo fdisk -l ; I get this:
Disk /dev/sda: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
[Code]....
This: Disk /dev/sdb: 160.0 GB, 160041885696 bytes is the drive I want to get my files off of. So ubuntu is reading the drive in some fashion.
