Last week I was trying to backup some files to External HD, because of some editing that is due in three days from now. I have spent that week using Tune Up Utilities, System Mechanic, Hdd regenerator, CheckDisc Gui, Advanced System Care, checkdisk, WinDlg, Perfect Disc, PDtt (or something like that) and many other trying to fix some error that was reported by windows whenever I connected the drive to Pc.
Finally I decided to go with that same windows utility that was reporting errors and everything went fine.
But today I was trying to defrag index files on fixed internal partition with Perfect Disc that is done during boot, and Chkdsk appeared and before I could stop it started fixing something and erased 200gb of material or stored it somewhere where I can't find it.
I can't find reports, log or anything.No indications of it in any of the utilities.
I revealed hidden files/folders, went through Total Commander view, even Nero, and nothing, no trace of chk files.
But I can see used space:
Advice, help please ,it's pretty urgent
