i have a serious problem in my computer....my system runs on win7 ultimate. there is a folder like icon(default win 7 icon) with a lock at its bottom left named "a705f30c64459f1d91f3e0dc988aa77f". i dont know how it was created.it was there in my 'd' drive....one day i deleted all the data in 'd' drive..it deleted every item other than that folder....so i formated the drive..it showed an error message and the format was not done...from then the drive is not working.. it shows 0-used space and 0-free space....i lost 120gb of free space... i formatted my whole system...reistalled the windows but no use :(...i thought it was gone and so i left it... and now the same folder with a lock is formed in my 1tb external harddrive...i scaned it for virus but it shows no virus..i also scanned it in my frnd's computer nd it also showed no virus....
I am not sure how to fix this and/or recover the 120GB lost. Any help is appreciated, thx!
