I've hit this problem before so I guess my real question is: Are tib files that are >20gig simply too large to recover, even on an NTFS file system, and even when nothing has been overwritten. It's probably a noob question but I don't recall learning about a size limitation for recovering deleted files. I'm trying to recover a 40GB tib file that I accidentally deleted --and obviously a 40Gig file by-passes the recycle bin. But the partition in question hasn't been formatted or touched since that simple deletion--so the MFT should just have a few bytes changed. Normally something like GetDataBack, Active@Undelete or R-Studio will do a sector scan, read the MFT and allow me to recover what hasn't been overwritten---but I don't think any of those apps have ever worked with a large .tib file. I suppose if I were still on top of low level stuff I could use Partition Table Doctor and go in and manually tweak the hex but it's been too long since I've worked at that low a level to know what I'm doing anymore. The best file recovery app I have is Media Tools Pro--and at 400 bucks per license it should be good--and it is. It does very low level scans to regurgitate boot records, MFT etc. But I'm not sure even that would work...I'm guessing after a file reaches more than a few GB in size that the number of pointers needed to find all the sectors gets prohibitively large and these big .tib files are simply not retrievable once deleted??
