Downside of going digital...... I had burned some files off the hard drive to CD-R a few months ago to free up some hard drive space, to my horror I now find some of the files on the CD seemed to be corrupted even when it is read by the same built-in CD-R/W drive of my laptop that wrote the original files to CD-R, an external DVD/CD R/W drive connected to the same laptop appear to have same problems with the same files so the problem appears to be on the CD media itself.
BTW, I gently cleaned the laser lens with PIC-pad and Eclipse isopropyl solution hoping it was the problem, it wasn't. All the MS Word and Excel files on the root directory of the CD seemed to be fine, but randomly there are some .jpg files in other folders that will not read, the drive will try for quite some time and then puts up an error message "Cannot copy file_name: data error (cyclic redundancy check)", sometimes I can see the thumbnail on the preview panel off to the left side of the Explorer window, but get the error message when I try to copy the actual file from the source CD, but I think at least on one occasion a file that appeared to be hung up initially was successfully copied at a later try, and one file showed just the top 10% on the Windows Fax & Picture viewer software. Of course this is the one directory that I didn't make a second back-up copy of......... Any thoughts on the cause of this problem? any thoughts on ways of recovering the images even if they are corrupted? (I'm guessing about 5% of the .jpg files on this CD are affected) Many thanks in advance.
