So me and my friend were installing Arch Linux on my external hard drive. My external hard drive had no data on it, ready to roll. My friend had partitioned my external hard drive (I am positive that there was no error in this part of the process), but after he had exited out of cfdisk, he had accidentally typed
mkfs.ext4 /dev/sda2 (my internal hard drive) instead of
mkfs.ext4 /dev/sdc2 (the drive he was supposed to format).
I asked, "Hey, isn't my external hard drive sdc, not sda?"
Then he starts freaking out, and he shut down the Arch LiveCD and tried to reboot into Windows (on my internal hard drive). Lo and behold, this came up:
Windows failed to start. A recent hardware or software chance miht be the cause. To fix the problem:
- Insert your windows installation disc and restart your computer.
- Choose your language settings and click "Next."
- Click "repair your computer."
Info: The boot selection failed because a required device is inaccessible.
I immediately held the power button until it turned off, and haven't turned it on since, in fear of doing something worse to my computer.
So, for my questions:
- Is my C: partition wiped, lr is it just my boot partition? I suspect it was the C: drive....
- I want to create a full binary backup of my (former) C: drive before I perform any rescue attempt, so I can do more than 1 attempt to recover my data. Is this even possible, and can I actually use this to actually do multiple rescue attempts?
- There are 2 major things I want to recover. One of these is my Compositions folder, which is in the C:/Users/MyName/Libraries/Documents/Compositions folder. These files have a weird extension (.mscz), which I doubt certain file extension-sensitive data recovery tools can find. Can some tools find files with unknown extensions?
- Do files in lower directories have a higher chance of being saved? Because my most important stuff is held in C:/Stuff.
- I would prefer that the software recovery tool would be free.
- I had deleted the HP RECOVERY partition a while ago, stupid me. However, I have quite a few Win 7 System Restores that were fairly recent. Are these on the C: drive? if not, can I use these to reinstall Win 7 after my data is (hopefully) recovered?
- I have a set of HP recovery disks, if those are of any help.
SPECS AND OTHER INFO
My computer is an HP laptop with Windows 7 x64 (single boot) a 750GB hard drive (~200 GB unused, 6% fragmented last time I checked. I only need to recover around 2GB of data; the rest I can easily replace). My friend has a fully funcioning computer, and I have an external hard drive (1TB) that I can use in the recovery procedure. We both have a couple of USB's that we can use as LiveUSB's.
