Hello. Let me start out by saying I store a lot of files. I have 8 external hard drives ranging in size from 500 GB - 4 TB, a 3 TB drive and a SSD in my computer. I am aware that data can corrupt on a drive due to bad sectors, and I run chkdsk every so often to make sure my drives are working with no errors. However, the other day I went to mount and install an ISO file that I had burned in 2010. I had installed it for years without problems but this time it gave me an error saying a file could not be found, yet the file was right there in the directory. I remade the iso from the original CD and it worked, so the data inside the first iso must have corrupted itself.
I also save a lot of pictures, and sometimes I notice that a picture that had been saved without any errors will look like it had been stretched into a thin line and distorted, which, because I had seen the pictures before displaying normally, I attributed it to data corruption. This is a concern for me because I save terabytes of data and if it corrupts this often it means some serious data loss for me.
That being said, is data corruption on hard drives this silent and common to corrupt files without the user knowing? And what tools can I use to prevent this? I have tried Spinrite, but it takes an insane amount of time on my 3-4 TB drives.
