Hello! I've moved tons of files to an external hard drive [Samsung external USB HD (FAT32)]. After that, I've tried to eject the device in Windows 7, via Safely Remove Hardware but Windows said that the device was in use, even though everything (applications and windows) were closed. I decided to use USB Safely Remove software to eject my portable HD. I really don't know if that was the problem, but since then I found a lot of folders inside my external HD corrupted. In the corrupted folders, JPG files looks like this. I can't read the other files (PDFs and PSD) in those folders, Adobe Reader and Photoshop says that the file is damaged. I've tried Windows 7 error-checking but the files are still corrupted. I would like to know if anyone ever had this problem. Does anyone have any suggestion for this? Is it possible to recover the corrupted files? Thanks in advance!
