I used a copier with scan function to scan a lot to picture, some in Jpg, some in PDF. After scanning, all files are able to open and read. I have the this problem (file corrupted) before, so I keep the original files (jpg and pdf) and use 7 zip to make compressed files. All the files(jpg, pdf,7z) are good at that time and I move to a external hard disk. I seldom connect my external hard disk to PC. And my working environment with antivirus software installed pc and system recovery.
Time pass, suddenly some of the original files can't open, some still ok. And I go to my compressed files. When using 7-zip to unzip ,error message come out " Data error in filename.jpg. File is broken". The process of unzip file like that. In case I';ve 100 files, number 1-20 is good at the original files as well as zip file. I can extract number 1-20 files form the zip file, the other files will show the error message. Number 21-100 files were corrupted in original file and also the zip files.
I have make few folder to keep my scanned files on that day. In different folder, most the first few files in each folder are still good no matter in the original or zip file.
Some corrupted jpg files can show a little original picture.Please see the attachment. Please download and open the file, the preview in browser is not the same to my corrupt file. Some corrupted pdf files can show the first few pages in a each pdf file.
And i search many forum to find solution. Only got one post have the same issue but no one can solve. If interest please go here
