General :: Recover Files From Ext4 File System Overwritten By New Installation
Jul 3, 2011
My main hard disk died and I replaced it. After installing windows in a small partition in /dev/sda, I thought I will try linux mint and went for it. (I need windows to play AOE, but ubuntu is my primary OS)I didnt see the options properly or some distraction, I choose the "install alongside windows" option probably expecting it to install it in the unallocated partition next to the windows installation. I had completely forgotten my second internal drive /dev/sdb which has the backup data. Linux mint went and installed itself on that drive.
Is there a way to recover individual files from the second harddrive. Now if I boot or open it through live cd, all I see in the linux mint file systems. I want to aleast recover my CV/resume from the second drive. The second drive is a single ext4 file system The old drive is completely dead, it doesnt even get recognized when I attach it to SATA.
I was syncing my palm pilot but some setting must've been wrong: instead of putting the files from my hard disk to the palm pilot it took the blank files from the palm pilot and wrote them over my back-up. Anyway, I'm about sick of palm but I want to get this file back. Is there anyway I can restore to an earlier version of this file? I'm about to reboot with sys rescue cd.
I had written a source code of C++ and complied it with the same name using the following command line.For example: c++ source-code.cpp -o source-code.cpp.Now my source code has been replaced by the executable program.Is there any way to retrieve my source-code.
I was trying to decrease the size of my main partition so I could create a secondary and install Windows 7 to.I was using Norton's partition software. My computer had to reboot and before reaching Windows XP it started doing the resizing. For some reason it failed in shrinking my main partition. I'm not sure if any harm was done while it was trying to do this.I proceeded to run the Windows 7 installer, under the impression I could just install Win 7 to the same drive and leave all my personal files alone. Right when the installation started during the "Copying files" stage I hard reset the computer after getting nervous and changing my mind..
I booted up Ubuntu Live and found that my main file system had been cleared, and only a few tiny temp Windows 7 installation files where there.I am sure there were no deep formatting done, only a quick format by the win 7 installer. there is any software I can run in Ubuntu to scan the drive for files to recover them, because the new file system overwrote the old one.
before i proceed,I'll like to say that I'm a complete newbie, but enjoying my time with Ubuntu.
Recently, due to hard disk failure, some of the System files got corrupted, I have no idea to which files, but booting Ubuntu from the latest kernel is not working, instead I have to select the previous version from the grub screen.
How to recover these files? Is there a way by which Ubuntu automatically scans and repairs the system files.
Accidentally, I deleted my '/etc' & '/bin' folder (i know, my fault). Then, I boot liveCD and tried to copy or fix this issue. And then when I can't figure nothing to fix it, I don't know why, I want install system on my existing system, and I thought that new installation don't touch and change my /home folder. And this step Was my biggest mistake, after this I get raw /home partition without my data. Now, I'm trying recovery my data from /home, and I don't know how do this. I'm using program testdisk but I don't know how it work with lvm and ext4. Can I recover content of '/home' or it's impossible?
I used the ext3 format when I formatted my partition prior to installing Ubuntu10.10. I had accidentally deleted a file and began the process to get it back. It wasn't critical but helpful to recover the file. To make a long story short I ran into to some unexpected road blocks. I tried to use PhotoRec to get the job done but with no success.
I'm just looking down the road in the event I might have to recover something important.If it would be better going back to the Fat32 file system I would rather do it sooner than later. Just as a side note I am dual booting between linux and windows.
I have tried 4 times now to install but it keeps freezing. I wiped my hdd with a tool from UBCD and im starting fresh with a full install of Ubuntu 10.10.I'm installing from a LiveCD. Should I format the hdd in some way before install?
I have a Dell Mini 9 netbook. The SSD took a dump, so I ordered a Super Talent 16gb replacement. I put it in yesterday, tried to install 10.10 and constantly get errors. The first error, which I haven't had since, was [ERROR 30] Read-only File System. The install obviously failed. Wondering if perhaps the file got messed up in translation, I redownloaded 10.10, reformatted the flash drive (sandisk cruizer 4gb), put 10.10 back on via the program on the Ubuntu site. No luck, but no longer the [error 30]. Tried again using Unetbootin, no luck. Rinse repeat a few times, no errors just a working cursor spinning and spinning and spinning and spinning and.. you get it.
Tried to put WinXP on it just because I was that frustrated, no luck.
Now I'm back to Ubuntu (because let's face it, who wants to deal with Windows, christ they make it so complicated). I'm currently using 10.04 because I was hoping (praying) it might just be a 10.10 thing.
No such luck, now it goes to step 7/7, starts, and 5% of the way thry "creating ext4 file system" it says "the ext4 file system creation in partition #1 (0,0,0)(sda) failed." I have checked the SSD in the Disk Utility, SMART tests are clean. I have gone to terminal and run fdisk and had a smarter person than me look at the copypasta, no errors, I have deleted all existing partitions in gparted and started fresh. I have tried the auto partitioning, I have tried manual, I am going insane. Literally insane. My preschooler thinks I've leaped off the deep end.
Could it be my flash drive? Could the SSD be defective despite the tests coming back clean? What do I need to type into terminal? Is there a way to entirely entirely entirely wipe the SSD to make it fresh-out-the-box clean? I will happily provide whatever you need if it means I can get my husband off my back about this stupid netbook with its stupid tiny keyboard.
I was in the process of installing Ubuntu 11.10, but got stuck choosing which file system to use. ext3 and ext4; which is better for a personal desktop? If ext4 is better, will it work well on my old PC (bought 3 years ago), or perhaps ext4 is not actually compatible with an old hard disk?
It worked fine. While using 11.04 I encountered a serious bug in nvidia 270.41.06, and decided to switch to Kubuntu 10.10. I installed 10.10 on the very same /dev/sda5 (clicking a checkbox to format it). Everything worked fine, grub was installed and pointing to win7, and kubuntu 10.10. I disabled ext4 journaling as above, rebooted, and found, that grub now points to win7 and 11.04, and that system (which should have been removed during installation of 10.10) loads perfectly fine. I checked where 11.04 had been installed - still /dev/sda5. Win7 loads fine as well, so no linux on /dev/sda2 I checked if there was 10.10 kernel in /boot - no. File system on sda5 had no trace of 10.10.
I formatted sda5 with gparted, installed 10.10 again, disabled journaling and situation repeated, whole file system on sda5 changed. Enabling journaling did nothing, 10.10 didn't come back. I deleted sda3, sda5, sda6, made them again, installed 10.10, disabled journaling, and finally had my 10.10 on ext4 without journaling. So this is kind of solved, but I would still like to know that the hell happend? For the moment it looked like two file systems coexistened on one partition.
I can't seem to get past step 6 of he installation of Ubuntu 10.04. I get the error: The ext4 file system creation failed... on single partition (no raid). I chose ' / ' as the mount point, and have tried with and without a swap drive. I'm installing on a Sony VAIO VGN-NS160D, and the HDD was previously formatted to NTFS. There's no other OS so I don't see any way of getting a command line to try a sudo fdisk..
I have accidentally removed vmware virtual disk, my host operating system is RHEL5.2 with ext3 file system, i have used photorec, magicresue and foremost but still no luck to recover the vmdk file. i have seen in foremost configuration file that there are some predefined files (ex- doc, pdf, jpg, avi, zip, etc),
1. is there any way to add vmdk file extension on that configuration file?
2. if yes how can i do ?
3. by adding vmdk on configuration file, can i specifically use recover option for vmdk?
I removed my Ubuntu install and decided to replace it with Debian. I backed up the /home directory onto the Windoze installation on the other hard drive. That was a "home.disk" file. Now, I copied the file over to the Debian hard drive, and can't figure out how to recover the files. Is this possible to do in Debian?
In an attempt to shrink my Data partition on my 500GB drive I had succeded in shrinking it but I think I have broken the partition table as now it refuses to mount. When trying to mount I get this error mount: wrong fs type, bad option, bad superblock on /dev/sda2 I have done some searching around but most fixes haven't worked because they are based on ext2/3 File systems and this partition is ext4. Using Ubuntu 10.04 x64.
I grabbed the new lubuntu 10.10 from [URL] but it turns out I'm having a problem installing it on my netbook (Asus Eee PC 1015PED). While installing, this error pops up:
The attempt to mount a file system with type ext4 in SCSI2 (0,0,0), partition #1 (sda) at / failed.You may resume partitioning from the partitioning menu.I'm installing via USB and have selected the option to erase everything and use the full HDD.
How well is the ext4 new file system mounting compatibility with the older ext3 previous Linux installations ? I refer to Ubuntu 9.04 and the new Fedora 11 which have the option to install with the ext4 file format. Will it be better if I install with the older ext3, so that I will be able to mount all other Linux from each other in a multi-boot system ?
On my drive I had 2 partitions for an Ubuntu 9.04 (swap, /) and one partition for Windows. I figured out that I should upgrade my Ubuntu, so I deleted the "/" partition and in its place created 2 new partitions (/, /home) .
After installing the latest Ubuntu 11.04, I realised that although I had backuped everything I needed in a 2nd disk and I could access those folders and their data from my Ubuntu 9.04, both my Windows and the 11.04 can locate neither the folders nor the data now. I have no idea why this happened (perhaps some issue with the mounting?) I have tried the trial version of Stellar Phoenix linux data recovery tool, but it cannot locate the old partitions.
Last night I made the mistake of formatting my media drive. Before the format, it was ext4. then I formatted it to ext4 again because I wasn't paying attention to what I was doing(this mistake only gets made once). Now im looking for away to recover any/all of my data. The drive in question is 1tb. I have not written any new files to this drive.
I spent about a year on linux and had all sorts of very very important documents and files saved in my system. I cannot stress the importance of these documents and know that I am retarded for not making backups. We will start another thread for people to yell at me if you want. Heres the deal, XP was installed on this computer yesterday. They did a boot from disc install, deleting the partition and installing a fresh copy of XP.
Now XP is back on this cpu. My question is, is there ANYWAY long, short, whatever that I can find those files or maybe go back to my old install of ubuntu? I've heard a lot about bootloaders and whatnot but I have to get those files. I have a bunch of assignments due and need these files.
I see that F11 respin Omega-Pug live CD is available for download. Before I use up the bandwidth, can someone suggest if the file system default installation is ext 4, as in F11 live cd, or can one now choose ext 3. The reason I am asking is that mine is currently ext3, and I would not like to lose my /home partition, with all the stuff that has accumulated.
I recently upgraded to Ubuntu 11 and a few days later my ecryptfs filesystem began misbehaving in a weird way. In my home directory, many subdirectory names are duplicated verbatim. Here's an ls -F excerpt:
I can no longer access files in those directories (if I ls the directory, it appears empty; I can cd to it, but there's nothing inside). Not all of the directories are duplicated/damaged like this, but most are. A few non-directory files are also duplicated in this fashion, so for example:
