It may have been a good thing I did it this way, though, in case there is some kind of problem with flash drive images or mounting them/images in general. If I already had the destination flash drive in my possession, I would have just done a direct copy to copy from the Lexar to the PNY. Plus, I believe SATA HDD is faster than USB 3.0 flash drive, so the read portion of the copying should be faster.

The imaging could be done while I was gone when the computer would effectively be idle. Knowing I'd be gone some time, I decided to just image the flash drive while I was gone and mount the image for copying later. But, I needed to go out and get it from Office Depot. I planned on copying over the flash drive contents after I got the flash drive. Well, I admit, I got too cute for my own good here. Could be a cable issue, but it would be an SATA cable issue. The image was stored on an internal SATA HDD.

I recorded which file failed Verification so I'll capture a 2nd image of the Lexar and try a manual Verify on that mounted image. How would I perform a hash comparison? I've never done that beforre. So, this has me worried that the image contents may not reliable when imaging flash drives. The contents were NOT corrupt on the source flash drive. So, I inserted the Lexar source 256 GB flash drive to compare the contents from the original source of the image to make sure the set files weren't corrupted on the source flash drive. I then performed a manual Verify on the mounted image file contents to make sure it wasn't corrupted in the image and was the fault of a bad flash drive like the last PNY 512 GB flash drive I tried, which was junk. I got a data verification failure on one of the images I copied over from the mounted Lexar image on the image copied to the PNY. After each image set was copied, I ran a manual Verify on each image set to verify the contents were copied over.

I then mounted that image and began copying over some of these images to a new PNY 512 GB flash drive. I imaged a 256 GB Lexar flash drive that mostly had Reflect image backup sets on it. This has me a bit worried about the integrity of images made from flash drives.
