Data Recovery and Disk Utilities Forum @R-TT

Different data recovery programs use different file system parsing algorithms that is why they give different results. I'm sure there are cases when R-Studio recovers all files, while extundelete does nothing.

I'm sure that's true - it's just that I'd heard such wondrous things from other folks ...

Hi all...

I've posted about this before, but I got reorganized to check my work, and the free utility 'extundelete' is finding many files I deleted from my EXT4 partition, whereas R-Studio is finding the top-level directories under the root, and nothing more.

How can this be? extundelete mostly ...

Well, I set my paging file to grow up to 512gb, and at about 1/3 finished it's already grown to 100gb or more when asking to look at files it's found.

Once again - I get the feeling that R-Studio is bad at memory management when doing it's job - either that, or it somehow thinks that every block is ...

Well, both scans completed. However, in attempting to load the scan in the "Extra Found Files" section, all available memory is being taken up, and the pagefile is growing to what looks like the max size of the partition (which is 45gb). I predict a crash soon.

If so, that means I'll have to move ...

It fills them with the pattern virtually, during recovery, correct? It doesn't actually write to the disc being recovered?
Sure! R-Studio never ever tries to write anything on the disk.

In any case, R-Studio has been running all night, and says it's 95% finished (which is a lot further than it ...

Well, the area where R-Studio can potentially crash may be quite small, so one or two files would be missed.
Excluded areas are areas that R-Studio fills with a pattern for bad sectors. That means the files spanning across those areas would have that pattern in them. Maybe, some of such files could ...

I mean a little bit different thing: start scanning from the point where R-Studio crashed without loading the scan info. Does R-Studio still crash?

Ah - that's one I haven't yet tried, as I'm concerned about the issue of files spanning the sections scanned. Probably not a HUGE issue, but enough ...

I assume that you saves the scan info to a file. You may load it later and resume the scan. Moreover, even if R-Studio crashes, the file remains valid.
You can scan the disk in parts, read more about it on the R-Studio on-line help: Advanced scan .
You need to select only the Ext file system for ...

Which version do you use, 32- or 64 bit? Assuming that you have 8GB of RAM installed, your OS's are 64-bit Windows and Linux. Am I right?

I successfully used the 64-bit version of R-Studio to recover a 5 TB RAID 5 consisting of 5 disks (app. 3TB of digital movies). But it was done on a dual-Xeon ...

Hey folks...

I accidentally deleted ALL my files (mostly my DVD collection, ripped onto hard drive) from 2 3tb hard drives, formatted in Linux with EXT4.

I heard good things about R-Studio, so tried it; the Windows and Linux versions crashed every time I tried to scan these drives, and the ...
