Recover My Files Software anomaly ?

[sarah_louise]

I am reviewing some software GetData Recover My Files.
I am testing by going through a number of USB memory sticks.
I have found limited success recovering files that are just deleted normally but almost 100% success if I then quick format the drive.
Does this make sense to anyone as it seems opposite to what I would have thought.
Can anyone explain why ?

Does to me. If you delete a file and later try to recover it, it could get partially overwritten by another file. Also, when you delete file, its entry in the FAT index is changed on an individual basis, whereas when you quick format, the FAT index is removed en bloc,so to recover all files in such a situation, it's only necessary to restore the index, and all the files will magically re-appear.

basically the fat is a database and deleting a file simply changes the first letter of the file name into a greek "alpha"

so undelete simply asks you what the first letter was

there are two varieties of flash - real flash which follows the ide standard ... and not real flash which doesn't ....
it's cheaper that the real thing and works in a different way.

I think also (not certain about this) that some of the non ide memory switches off the capacitors which hold what would be the FAT info and so there is nothing to recover

Thank You for that.
