No, unfortunately. If the file records are recoverable but the content of the file is overwritten, R-Studio may report no errors, but in fact the file cannot be recovered.Madumi wrote:Just a quick follow-up question... The recovery process seems to have gone seamlessly... If no errors are reported, can I be sure all the files have successfully been recovered?

Re: RAID0 - partial recovery (parameters?)
thanks for your reply.
OK, yes, I understand the problem of overwritten files. I don't know if a broken RAID0 array creates overwritten files. When I did the recovery saw that I could recover deleted files, but I only attempted to recover the directory/files that had not been deleted by me.
I guess if a broken array could delete files, I understand they could be lost without trace. I didn't see evidence that files were missing. If a broken array deleted files, would the evidence be an odd file here or there, or would it be larger scale?
thanks!

Re: RAID0 - partial recovery (parameters?)
You see, R-Studio analyses the remnants of the previous file system. When it finds a valid file record it assumes that this is a valid file. But it's impossible to evaluate whether the disk sectors belonging to the file have been overwritten by some other processes.Madumi wrote:thanks for your reply.

Re: RAID0 - partial recovery (parameters?)
Aaah, yes, thanks... What I meant to say (sorry for the mis-communication) was that I'm not worried whether the contents of the files are valid. I'm wondering whether if the folder/sub-folder structure seems correct (I can't remember any glitches), whether it's likely to have holes elsewhere in the structure in places that are harder to find (eg. 5 folders deep). i.e. if the structure seems to have overall integrity, whether I can trust that the rest of the tree retains similar integrity (even if the files themselves may have been overwritten).Alt wrote:You see, R-Studio analyses the remnants of the previous file system.
