Recovering ext4 superblocks
Recently, my external hard drive enclosure failed (the hard drive itself powers up in another enclosure). However, as a result, it appears its EXT4 file system is corrupt.

Data recovery from an accidental format on ext4 partition
When I was installing Mint Debian edition unlike the classic edition, the installation automatically formated my home partition when I did not specify to format.
How to recover a crashed Linux md RAID5 array?
Some time ago I had a RAID5 system at home. One of the 4 disks failed but after removing and putting it back it seemed to be OK so I started a resync. When it finished I realized, to my horror, that 3 out of 4 disks failed. However I don’t belive that’s possible. There are multiple partitions on the disks each part of a different RAID array.
recovering deleted file held open by apache?
Suppose an apache log file gets deleted but it’s held open by apache; then this is what I am doing:
How to recover data from a bad SD card?
I have a 4GB SD card with some family pictures on it that I need to recover. When I insert the card into my card reader, it shows up as an unknown 32MB device (as /dev/sde) and cannot be mounted. When inserting back into the camera (a Nikon D60), it says the cards needs to be formatted (as does inserting it into a Windows machine). I want to recover all of the pictures on the card (there were others before the family pictures) because I don’t know how many I took or their exact sizes (but I believe they were all JPEGs). The card should be formatted as a FAT32 filesystem.
How do I find the offset of an ext4 filesystem?
I have a failing hard drive that is unable to write or read the first sectors of the disk. It just gives I/O errors and that is all there is. There are other areas on the disk that seem (mostly) fine.
I am trying to mount a partition (ext4) and see if I can access some files I would like to recover. Since the mount command supports an offset option, I should be able to mount the filesystem even though the partition table is unreadable and unwriteable. The problem is how to find the offset. None of the ext4 tools seems to have this particular feature.
undelete a just deleted file on ext4 with extundelete
Is there a simple option on extundelete how I can try to undelete a file called /var/tmp/test.iso that I just deleted?
Using ddrescue to retrieve data off a failing ntfs disk
I am attempting to save some user data of a disk that has failed in a Window 8 computer. I’ve removed the HDD that was unable to be read by the Windows 8 laptop, plugged into my OS X machine which can see the partitions but cannot mount them. (ntfs-3g cannot either).
recovery data from RAID and disk failure (Linux)
1st attempt: Mounting disks alone
How can I access a deleted open file on Linux (output of a running crontab task)?
I have an hourly hour-long crontab job running with some mtr (traceroute) output every 10 minutes (that is going to go for over an hour prior to it being emailed back to me), and I want to see the current progress thus far.
