comment How to save a ntfs partition which suddenly became empty
@NicoleHamilton: So Windows has extended the maximum length of paths. But there is still limitation. How about Linux (Ubuntu)? I upvoted your answer in another post, but wasn't able to comment due to my low reputation.

@Synetech: I haven't written anything to the partition, unless Windows did. I also made an image of the partition as soon as I could. Then I ran RStudio on the mounted image. That probably explains why I am able to get most of my files back. (1) What was RStudio bad in your case? (2) I heard there were some professional services www.krollontrack.com, and www.drivesaversdatarecovery.com with relatively good reputation. But they charge high > $1000. Can they possibly have their own not-revealed secretes that will do better job than those programs we have tried? Or just rip off our money?

comment Ways to improve completeness of files for data recovery and scanning?
Thanks! Most of my files on that ntfs partition were created under Ubuntu. If I remember correctly, defragmentation isn't necessary under Linux, isn't it?

Thanks! So UTC time and local time are different, but the times under both OSes are both 4 hours in advance?

Just to learn about the basics of data recovery, not actually dreaming of writing a tool my own. :-)

@NicoleHamilton and Synetech: Thanks! What does it mean that the time shown by both Windows and Ubuntu has been changed to be 4 hours in advance? I now start to worry about the cause of my partition being wiped out, virus, disk failure, corrupted filesystem,...?

Thanks, Karan! (1) WHat are some good applications that can help sorting through the debirs, comparing copies, etc? Under Linux (preferably) or Windows? (2) What do you think about the strengths and weaknesses of the 3 tools? In my case, most files were created under Ubuntu with too deep paths to be handled by Windows and software under it, so I ended up purchasing R Studio for Linux, although data loss happened under Windows. The other two tools seem to work under Windows only, and likely not able to handle long paths. (3) Are there some good books or references for data recovery algorithms?

I tried Recuva before, but my paths are too long to be handled by it under Windows. R-studio has a Linux version, which may be more helpful.

Another possibility to my question: does data recovery software scan in some storage unit, like 64 KB, 16KB, ...? So if decreasing the scan storage unit to 1 byte, will that improve the quality of scanning and recovery? Note: I am just guessing, and not sure if software for data recovery works in that way.

Thanks! Does changing the partition to be read-only to all users (system, administrators, ...) protect it from being written?
