(solved) Accidentally "formatted" running drive using Fat32Formatter

#1 Post by krs7 » 15 Mar 2016, 22:05

Hello everyone!


I know someone posted a very similar case some years ago but I still haven't found a solution - so I opened the topic.

I currently have the folowing problem and I hope someone could help me:

I wanted to format a microSD card using Fat32Formatter.

Accidentaly - the wrong drive was selected (my running SSD Drive with Windows) and after i clicked "initialize drive" the Laptop crashed: Bluescreen etc.

Restarting the PC doesn't help - no drive is found.

In my experience "initializing drive" doesn' format it, but it makes the drive space "unallocated"

Someone posted in another Forum that he managed to get his system back running with testdisk after the same problem so here I am.

Assuming I just have to create a partition Table, I created a bootable USB.

Testdisk doesn't find any recoverable partitions in the quick search, but in the Deeper search.
I actually have only one partition and testdisk is finding more that one and I am not sure which one to select.

so I just tryied it :writing the partition table. I tryied this procedure a couple of times but now I get annother error:

I don't get the error 'no drive found "
when starting, the Windows Bluescreen is reporting that windows needs to be repaired and I would need to insert the Windows CD/USB in order to start the Windows repair process.

So - before I make any more damaged I figured maybe someone can give me some usefull advice: maybe which partition to select or if it would be OK to start the Windows Repair process.

Also: Just started Gparted.
at first Gparted showed the hole ssd-drive als unallocated( 240gb)
an now I get:
/dev/sda1/-------------NTFS-------------System------------1,46GB------------boot
/dev/sda2/-------------NTFS-------------tI3136300B-------211.66GB----------no flag
unallocated-------------unallocated--------------------------10.44GB

I was using Windows 10 Pro 64 bit (didn't even write down the windowskey after the update from windows7)
I am using testdisk with the Gparted Live Bootable USB

I will post some shots so you can maybe unterstand the problem better. (I can't find he log file )

i'm very grateful if you could help. thanks in advance.

Run TestDisk, Advanced, for each partition, try Boot, RebuildBS, List. If you can see your files, choose Write and confirm.

You probably also have to use "bootrec /fixmbr" and "bootrec /fixboot" as described in

Hi!

So I've tryied to follow the instructions.

Boot- rebuild BS - List

after the rebuild BS I get the followings message for both partitions:

Boot Sector OK
Backup boot sector: OK
Sectors are identical

Under List I can see the files.

after that, you posted "f you can see your files, choose Write and confirm."

so know I have 2 quiestions:

1. after "List" I can't seem to find the write and confirm option.

in which submenue should I look for it?

or do you mean analyze > quick/deep search and write partition table !?

2. I would have to run "bootrec /fixmbr" and "bootrec /fixboot" from the recovery console.

to get to the recovery console I would have to use a Windows 10 Boot-USB, right ?


Thanks again.

After RebuildBS, List. If you see your files, use Quit to return to RebuildBS results, here you can choose Write.

Copy/paste the testdisk.log file content if you need more help with a description about the actual problem (it may have evolve since your first post).

Hi!

I've tryied these options but : if I go back once, I only have the options "dump" "list" and "quit"
if I go back with quit a second time I get "Quit" "List" "rebuild BS" "repair mft" "dump" so no "write" option.

the only write option is after "analyse" and "deeper Search"

I am using testdisk 7.0 2015 from Gparted live disk, and from this interface I can't acces the testdisk Folder to get the log file. Should I try another boot Medium??

Hello again, I just did not find to the existing log file (I have been using Gparted Live from a boot USB)
So i ran testdisk from the ultimate boot cd (testdisk version 6.9)

Here I could find pretty quick the log file
From ultimate boot cd i Just ran "analyse" , "deeper Searche" and "rebuild BS" for both partitions and "list" - after that "quit" - beaucse here I also had the "write" option only after the analysis and deeper search, not after the rebuild

anyway, here is the log, hope you can see something that helps
thanks

A valid NTFS Boot sector must be present in order to access
any data; even if the partition is not bootable.

TestDisk exited normally.

When you are listing the files from the partitions System and TI31361300B, do you see your files ?

Hello everybody.
I just wanted to let you know how I solved my problem.
Using the windows ISO cd didnt help. I could not repair the startup process and I could not reset the Windows because Windos repair could not acces the windows files.
I was almost giving up but I still tryed some options with testdisk. After i re-wrote the partition table for all 6 partiions, I still got the same error. Then I observed the primary partition is set to a 1500 mb partition so I changed it to the 210 GB partition. ---and it worked!!!!! so...that was the succes! :mrgreen: :mrgreen: :lol: Windows is booting!
I think pretty easy an probably have had to see it earlier - but better too late than never

Anyway - thanks a lot to cgrenier for the support and of course for testdisk!!
