What is a good windows data recovery software ?

i don't know why its not recovering the rest of the data .

Well, you said it's corrupted. Could be mechanical damage or other types of failure. You would only know more if it were professionally examined and the platters dismounted if need be. £££££££s

To determine its state, out of curiosity only I think, try Hard Disk Sentinel (excellent) - not data recovery.

There's Testdisk - use with great caution.

It sounds like more basic programs such as Recuva won't help you.

Presumably you will now ensure you have backups...

My external HDD is corrupted .
I tried to check the contents in it with an Ubuntu live cd but the external HDD is showing empty . I think i lost a terrabyte of documents , software and photos

Are there any good software i can try to recover data from that HDD .

I have used disk drill on it before but it was only able to recover 4gb of data from it . i don't know why its not recovering the rest of the data .

Thanks

jumanji may be able to help you. Don’t do anything more on it until he replies.

Glad it’s working for you. Great news.

Wow , Testdisk is an awesome software

I connected the external HDD and ran the software .

It has recovered this much amount of files:)

Warning .... Just hang off the euphoria and celebrations until you can check that the files are actually readable and useable.

I'd be doing the "recovery" in bits and pieces just to make sure it's not wasting your time with false hope.
