Need help with damaged partition

#1 Post by bina » 08 Jul 2012, 19:16

I have a 1TB hard drive which i partially formatted.

I used TestDisk and ran Analyse. Here's what I got:
search result1.tiff
search result1.tiff (20.18 KiB) Viewed 1823 times
stuck at this point as i don't know which partition to choose:
search result2.tiff
search result2.tiff (14.83 KiB) Viewed 1823 times
Here's the log:

have you seen this guide ?

http://www.cgsecurity.org/wiki/TestDisk_Step_By_Step

i found it helpful

I see you used v6.13. Are you using linux ?
Do you know what your goal is ?
Like what partitions you had before and what ones you are after now ?

Also if you actualy formatted a partition that doesn't sound too good..
Did you mean to say you deleted and/or created a partition ?
because that is different than formatting (in case you didn't know)

Looks like your partition table is wrong.
That's why the menu advanced doesn't work.
In your partition table is a FAT16-partition larger than 32 MB.
It uses probably the whole space.
Would it be possible to repeat your diagnose?
You can copy and paste the testdisk.log.
I'd need infos from Analyse and Quick Search.
If no partition would be found, from Deeper Search also.
If a partition is found, please check it and press p to have a try to list your data.

@Fiona & xpmule
i've decided to just reformat the whole hard drive and start from scratch. the files are replaceable and it takes 12+ hours just to scan the whole drive. I've run out of patience.
SO I will not be needing your help but thanks a lot for replying to my post.

EDIT: one more thing can you give me some tips on how i can format my drive to use on linux and windows. like which is the best filesystem to use. will really appreciate it.

i hear ya.. i just gave up on fixing my partition problem
i got it restored but can't mount it in windows so i decided to try
paragon partition manager to fix problems and it didn't help but it
has a built in volume explorer and that opened my missing partition
instantly rather than a recover program i tried that took 8 whole hours to scan first
and now at high speed im exporting my lost data with directories + folder names etc
my only problem now is i dont have 800gb free space to back it all up on my spare HDD's
so i have to pick and chose a select 2/300gb's of data i really want.. o well better than nothing

to answer your question ;)
i've used many linux distribs over the years and found that
now a days they can mount ntfs partitions so what i usualy do is dual boot
and when linux is running it will either auto mount my ntfs partitions for me
or learn the commands to do it manualy.. google might be a good idea ;)
and i'm not sure what you want to exactly ? share a drive between both *only for storage
or are you gonna use the partition for one of the OS's AND storage ?

There are no best file systems. Reliable would be windows NTFS and Linux ext3 or ext4.
Easy BCD for Windows is a good solution to handle multiboot from windows.
Also you can use grub if you want a Linux boot manager.

@ xpmule
Unfortunately, I can't judge your situation anymore.
It was necessary to write your right partition to the partition table.
Then it might be possible to have a boot sector diagnose to restore your partition directly.

@xpmule
I only want to use it for storage to share btw mac osx & windows (sorry not linux). so i'm looking for the best way to reformat it given the current state it's in.also is there a way to safeguard the hard drive so i don't accidentally format it again?

The most common solution would be Apple HFS+ and Windows NTFS.
If you use Apple, you can have a look at Bootcamp.
Most important thing is always backup.
