  1. I think Bitwar would be is going to be a regular l tool for me, I tested it today in few devices and all of them worked perfectly, very impress about it. Making the work more simple, thank you!

  2. It's amazing how good it works! I was about to consider the drive a lost case haha! I think it's completely worth it, you can get all the files no matter what, in a very simple way, wish I would of find this few years ago. Cheers!

  3. I think using Bitwar applies to many issues with external drives, most of the times is better to just format, which is great having a data recovery software like Bitwar to just get your files and then have a clean start over. Good job!

  4. Well I just tried Bitwar, easy, fast and very good results, my computer is kinda old, so I thought that since it is slow, a software like this one to recover files would take a lot of time but actually it didn't, so i recommend it to all the computers, thanks!

    • Hi, Emma, thanks for your kindly feedback, and yes if you tried with Quick Scan mode, it can scan over 1TB hard disk in 1-2 minutes or less. Even the Quick Scan offers the original file name and folder structure so that the user can filter the needed data as soon as possible. If you are having any questions or need our help while using the Bitwar Data Recovery, please contact us.

  5. Fastest solution I've seen so far! I've been jumping from different tutorials to fix and recover the files from my external drive but nothing really understandable or doable, until this. Thanks for letting me try Bitwar, great data recovery software without hesitation, thanks!

  6. Hello, first of all sorry if my question is a bit silly, I’m about to download the software, do I necessarily need to try the steps to fix the flash drive first? Or can I go straight to recover the files, because right now that’s all I want to do. Thanks.

    • Hey, Jamie, if you can see your hard drive in Disk Management, (Press Win Logo key + R and type diskmgmt.msc), then it's better to retrieve your important data before trying the necessary steps metioned in this article, after getting back the data, then follow carefully of the solutions step by step, if you are having troubles while fixing the issues, try to ask your technical friend to do your a favor. Thank you.

  7. I already tried Bitwar Data recovery software in different devices (flash drives, external ssd, and memory cards) works perfectly every time, incredible job!, it’s been really useful as an IT worker, I usually recommend this software because it’s the most simple and easy to handle.

  8. Downloaded Bitwar Data Recovery Software, few minutes later had access to all the flash drive files again, I manage to copy all of them in my computer, easier than expected. Indeed a virus was the main cause, is there a chance the virus also got in the computer by recovering the files? If so, what should I do? Thank you!

  9. I didn’t get that message in my flash drive, but after using it in another computer, suddenly said it was full, and there was a bunch of weird files with names I coudn0t recognize and saying they were 0 mb, couldn’t find MY files or open any of them so I had to delete everything in the flash drive. A friend recommended to use Bitwar software and it worked perfectly, got all the files back and zero viruses, really happy with Bitwar, would definitely recommend to everybody!
