Hi-

 

I had a question about data recovery on an external hdd. I am trying to recover data from a hdd that is telling me that it needs to be formatted before windows 7 will recognize it. There is data that I am trying to recover so it has not been formatted yet. 

 

I had used a program a few years ago to fix a similiar issue but I cant remember what the name of the program was. It worked great, recovered all my files from a formatted partition. I beleive it was a free program and was able to recover all the files, which was over 20g worth. I dont recall having to pay anything for the full version in order to recover the files. I have found several trial programs but you have to pay to recover the data and I dont recall having to do so with this program. Does anyone know the name of a similiar program? Thanks

When looking at the drive in Disk Managment does it show as RAW?

The problem with most ' free ' solutions is that they typically involve also installing a potentially unwanted program along with the program you want.  Here is a list of free programs however I cannot endorse any as I have not used any of them and I don't know which one would be less likely to have accompanying unwanted software with it.  But it may jog your memory on the program you were looking for.

Hi and welcome, 
 
It would be great if you give more details about the hard drive and the PC you're using. 
First of all, as JohnC_21 said - check what Disk Management says. RAW format usually means the OS can't read / doesn't see any information in the MBR/partition table to recognize any data, so it might be corrupted/erased. If that is your case you can try several options, but before that - keep in mind that the best solution for important data is Data Recovery Company.  
If you choose to do a recovery yourself you can try booting the computer with Linux Live CD, as this is a popular and easy way to read from corrupt partitions. Also take a look here: http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/bootcons_fixmbr.mspx?mfr=true
 
You can, of course, try a data recovery software as well - there are many cases of success, but there is no 100 % solution to your problem. I'll keep my fingers crossed.

I've had the most success with TestDisk in a situation like this. If the problem is caused by a corrupted partition table, which is a likely scenario I've recently sorted for a friend, TestDisk is good at locating the reserve copy if it is undamaged, and restoring it. You can assess from the file contents it lists for you if it has found a matching partition table and file directory. If restoring it is successful, it's then unnecessary to go through a file recovery process, the original files become accessible again.

 

In any situation like this it's possible the file system is damaged enough to make recovery difficult, and the drive itself may be faulty. However if it's clear that the problem was caused by something like an unsafe removal, and restoring the partition table brings it back totally, then the drive can continue to be just as serviceable as before. Thorough testing would be wise.
