Man that -really- sucks.

Well, at least now you're a member of the club! I feel like I can say a lot of us have been there, done that.

Run up a google search of partition recovery software. So long as you stopped right there you should be able to get something back.

hi all thanks for your reply...let me add one more thing...which i missed out...i have couple of application and ISO files of many software like ( SQL,WINDOWS7,MOSS,WINDOWS 2008 R2 Server set up, and other software tools) + aidio,vieo,office documents, will this recua re creates the structural and directory wise data recovery as it was before accidental formatting...psl advise currently one of my friend advise for me to run getbackdata...need a proper advise..found this forum deffinatly help me out to collect all my 7 years data which i had saved it...

If you actually formatted the drive (like with a deep format) rather than just killed the partition field accidentally, the data may not be recoverable, but that's not something I have much experience with.

IF you just deleted the partition and stopped yourself there, quite a few recovery programs can help you recover your data, but I am not familiar with one individually.

I would recommend you find one that seems to work, and then check and see if they have a FAQ or Forum and ask those folks, who may be in a better position to help you with that particular piece of software.

Good Luck!

No did not run deep format...i just ran diskpart and did clean up formated as fat / ntfs i dont remember...since after that i was not able to access my external 1tb then i formated as ntfs quick...that's it...

Hi...just need to know if i have formated twice by using dikpart command at first as fat32 and windows format second time as ntfs...will i be able to recover all my data...pls guide...since i have been working past 3 days still success rate 10% from different softwares...i am very desperate on this data...all my hard work stored..which i dont want loose...pls help..

I accidently formatted the wrong drive the other day and today I tried the Recuva software and I got all my files back , it has two ways to work one regular scan and one deep scan. When it's done it gives you a list of everything it found and I have to say I can't believe the stuff that this thing found. Not only my formatted files from the other day but stuff that was formatted years ago , it found everything that was not written over. You do have to try this software.

Whatever software you use, with what you did you HAVE to do a "deepscan" as inzone said with the software. You have erased (twice) the index to all your files. Kind of like taking a book, then removing all the page numbers, the table of contents and the index. The software has to scan through the WHOLE drive, find recognizable file structures, and the restore them. None of the FAT recovery type restores are going to do you much good. Also, not all file types are found by the different types of recovery software, so if you have some odd type of file, none of them may be able to find them.

i just ran today tesdisk found this information after analysing the disk..attached for your information pls help in step by step process if there are chances...

Hi Can anyone can help in understanding hardware status and provide me with possible steps to recover my data...will be ever greatfullis some one canhelp me.

I trid the testdisk software and it was kind of confusing and I then tried Recuva which was so much easier when it was done you change the viewing format to tree and it lists the data it found just like you would see it in windows when you open a drive . All you have to do at that point is highlight the file and select recover and you can point to where you want to send the recovered file amd then it's there. Done.
