S.O.S. ! I am new user of Mac and was heavenly happy with it until I made the huge mistake to not eject the external usb drive before unplugging. I had there important documents, supposed to be safe in a back-up on that usb stick. Next time I plugged-in the usb drive I found out all the data were lost! Now I see on my usb drive only the main folders names, but folders are completely empty - all the sub folders and files have been lost. I tried the same drive on a PC with Windows 7 and it showed the same, files are missing. Can the usb drive be damaged or this is Mac's punishment for not following instructions to eject prior unplugging :-( I tried some recovery softwares, but those found only small part of my files. Could you recommend me a smart way or powerful software, able to recover ALL my so important info? Thank you in advance!
