Recuva stop recovering at 50% of the filesize

Recuva
1

I've problems to recover my data from a WD30EFRX-68AX9N0 the filesize from the lost data is from 3MB up to 25GB. I run the scan and have pretty much results, but if i start to recover the process stops at exactly 50%, each file!

So if i try to recover a 3MB file ive got 1,5MB in my output folder, 5GB ->2,5 and so on...

i changed the output devices but it affect no change.

OS: Win7 Pro 64bit

HDD: WD30EFRX-68AX9N0

Filesystem: NTFS

phys. sector size: 4096 Byte

log. secor size: 512 Byte

How can i recover the full datasize?

thank you in advance

try running windows chkdsk program

if it says it needs to reboot to do it say yes

I usually do both checkmarks maybe others don't though.

Thank you for your reply. Your suggestion doesent work for me, all files complete only to 50%.

On other HDDs i can complete to 100%. i've only trouble wity my 3TB HDD.

Thats nasty, i can see the files but cant complete em... :unsure:

If you right click a file and choose properties then Advanced there is an option to Compress the file.

I think Windows Explorer list such files as having the originally uncompressed size,

but the properties will show not only the uncompressed size of the file but also the much smaller "Size on Disk" which might be half the uncompressed size.

Is it possible that what you are seeing is the "size on disk" and not the natural size when Windows expands it ?

No, i would be glad if it was the reason. But thanks for your help..

The explorer properties says i.e. for an 1532 MB file:

784.629.760 Bytes size, and 784.728.064 Bytes size on disk, which is equal 748.36 MB. In fact is my problem that recurva stop the recover process at 50%.

Update: I found a curious situation. If i recover a 'desktop.ini' (86 Bytes) he completes 100%. I also can open the ini and see the information inside!, but if i try to recover a 3 MB mp3 or a 2 GB mkv i get only a 1.5 MB mp3 resp. 1 GB mkv file, which is not playable of course. :huh:

might he complete only 50% if i change the clustersize i.e. from 8096 to 4048? I try to understand why it doesent work for me.

What is the cluster size of the disk you are recovering from, and the disk you are recovering to? I don't think this is the problem, but it would be helpful to have this info.

Both have 4096 bytes, but i dont know what the sectorsize was before i formated the HDD. It was just an idea

What caused the loss of the data you now wish to recover ?

Was that format part of what led to data loss, or your very recent action hoping to assist recovery ?

N.B. 4096 byte sectors appear to be standard as sold according to

The HDD was in my server and ive make a mistake and cut and paste some files, which were corrupet transmitted. So i tried to get the data back but ive make a 2nd mistake. here's the short version the partition table lost and i fromated the disk. -.-

Now i try to get the deleted data back, which were lost by the cut and paste command. The Data which were untouched is recovered with testdisk successfully.

Maybe it depends on the interface? It was plugged to a 3 Gb/s Sata 2 Port, after a while ic changed it to a 6 Gb/s Sata 3 Port, but which is downwards compatible.

What size does Recuva say the files are before the recovery, half or full? Are you running a normal scan or deep scan?

Im running a deep scan, and recurva display the full size of the files, but stop the recovery process at ~50%

Is there anything i can do now?

15

I see, my question wasnt very productive.

Thanks a lot for your time.

Your suggestion doesent work for me,

???

in what way? did it find drive errors?

Version 3.45 out today

"Added support for 3TB external drives."

That is relevant following your second post at #3

No the filesystem was fine and has no errors. After the disk checking nothing changed.

Thanks anyway.

Yes excelent timing! :D Now im checking the disk one last time. This would take several hours, so i'll keep you updated. If it dont work, then its dont mean the end of the world for me. :o

I already accepted the fate of my harddiskdrive.

Cant test it anymore, I had to put some Data (a few GB) on the disk and he cant find the files anymore but i expected that.

Anyway! Thanks for your support.

Cheerio!
