I have two XP Pro folders with about 500 meg each of files in tif, jpg, mpg
formats. I maintain copies on a second computer. Two days ago I scanned some
recent analog photos into one of the folders. The backup computer wasn't
available, so to be safe, and because I wasn't sure what had previously been
copied to the backup computer, I copied the entire two folders to two CDs.
Yesterday morning I opened several in each folder on the computer, using
Windows Picture and Fax viewer. No problem viewing photos from each folder.
Today I went to view again. One folder is fine, untouched. The second folder
showed every file (about 250 total) in each of its subfolders as the correct
Created dates, but all with Modified dates between 4:28 and 4:30 PM
yesterday. All file names are unchanged. All files are corrupt. The computer
was on at that time, but not in use. Folder properties are unchanged. I
looked internally at several of the files and they show header information
totally messed up.
I maintain a pretty clean computer. Router, ZoneAlarm, Anti Virus, Pest
Patrol, Spam checker, etc. etc. I would attribute the problem to a random
glitch, power surge, etc. except that a similar event occured in February.
I.e, a single folder of digital pictures corrupted in the same way, but all
other folders untouched. At that time I attributed it to a random glitch. (I
don't really buy the random glitch thing - I thought it was something I had
done in error without recognizing it.)
Fortunately I have the backups. But I obviously have a problem. I did a
search of all files on my computer with date/times of yesterday afternoon.
None were written near the same times.
Has anyone seen this occur?
Thank you,
