Damage to stored images. Hard drive issue?

Lately I have been collecting my better images from various hard drives (SATA spinners) to winnow them to fewer (best) choices to store these on SSD drives. I'm surprised to find damage is the form of a series of dashed lines running horizontally across some images. Looks to me as though the scribe/stylus in the HDD has dragged across the disc. These are in a desktop unit that stays in place, so not jarred in transport. Weary of correcting these lines. As would be expected they seem to only appear on my better keepers. View in download.

This is not the way a hard drive works. The heads write and retrieve the data from the surface of the drives without touching the drive platters. If the heads had touched the platters you would probably not be able to retrieve anything from the drive. To the system the data is just 0's and 1's. It doesn't know that it is a photo or a text document when it's retrieving the parts of the file. I would suggest that you look elsewhere for the problem. Possibly a software or video issue. Have you tried viewing the files on a different system?

IF Windows right click on the drive, click on properties, then tools, then error checking. It won't change any data, just check for errors.

Not yet but will now. Thanks.

Isn't it much more likely you made an inadvertent / unnoticed error in the PSE processing of this image? These are an overlay, consistent and exactly parallel. It may seem like bad luck, but luck doesn't consistently attack specific images. User error does though.

If those lines come up in exactly the same spot everytime you open them, you've got the buried in the image somehow. Hopefully it's in a separate layer & you start peeling them off until found.

You would know if the file was actually damaged as it would pull up as smeared or not at all. If you still have an unaltered RAW, pull that up. I don't think you'll see these artifacts in the unaltered original.

I agree. If there was a mechanical issue with the drive, you would not be able to read any files.

Errors at times seem to be my specialty. How would I make this happen? It pops up randomly. Mostly in images that have been stored for some time, over a year or so at least. I do only basic adjustments, not familiar with anything advanced. Very odd. Always stored as tif, converted to jpg to share on FB. Thanks for looking. If the issue clarifies I'll share it.

Can get random disk errors if you use the power button to shut down a computer as opposed to using windows shutdown function. It usually happens to the last file that was left open.

Here's a case for always retaining the unmodified JPEG or the original RAW file. That way, you'd see the issue was added in the processing. The "history" of this image references an initial conversion from CR2 via LR. Knowing LR does not modify the original, as well as you cannot modify a CR2 file, can you go back to the RAW and start over? Guessing at what happened in the past, without a time machine, is not possible.

I've been trying to think about a way to save the originals, there would be sooo many. Definitely needed. Yes, this did occur after processing fairly recently actually. I haven't run into it before the last couple of months. It's always been the older files. Especially 2014. Lines are not in the same spot and vary from 2 to 5 lines but not always on consecutive files. May have been the software I used then, but some I have posted in the last two years and were not a problem then. i'll just have to live with it at least it is not on every one.

Have you tried a different image viewer program? Irfanview is freeware (windows). I've used it for over a decade and it's on all of my computers. Just to see if the problem repeats.
