I posted this question on SO, and they told me to post my question here instead.
Before anything else, I tried to see first if there is a tag for data recovery. I believe this question is appropriate to be posted here on Stackoverflow, since I have read a quite similar question to mine on this website too, but I'm still confused and my scenario is a bit different. This is a simple question, but hear my explanation too
I have two external HDD that got infected, apparently, by a virus. Most of the files went missing.
The first thing I did was I put those external HDDs into my macbook pro, and see what this machine can do to salvage her data. Result: failed. No folders were hidden nor locked. There must be a bigger step to do next. It seems the files were deleted. I then downloaded two softwares, both full version to activate their all features.
- Disk Drill
- Cisdem Data Recovery
Both of these softwares did an awesome job. They successfully scanned (full scan) both of the external HDDs and I was able to export the recovered data into my machine. But most of the exported/recovered files couldn't be opened.
I tried the quick scan and few files were exported/recovered. But the good thing is that those files can be opened and viewed.
I thought a jpeg recovery software might save those exported/recovered corrupted photos. So I downloaded this:
- Stellar Phoenix Jpeg Repair
That software is full version as well. Unfortunately, it wasn't able to fix a single JPG file.
Finally, my question is: Could the data recovery centres actually 'recover' my files? Given that I have tried all the necessary steps I mentioned?
