Hello everyone, first post here.
I'm a bit concerned about the Health of the following Drive a 2TB Hitachi 2xSata. So this is what happened: I set up a copy operation in one of the drive partitions, about 500+ GBs during the copy operation two times my Computer case/tower was hit by my chair, effectively moving the whole case and making it shake or lean towards one side. As I know how susceptible hard drives can be I decided to check the whole state of the files to ensure everything was okey, since to shake your hard drive during a full read/writte operation doesn't seem like a good combination, I created a full MD5 Checksum of all the 39.000+ original files. I kept and didn't delete the original files of the copy operation for this purpose, and to have a backup in case something went wrong - I prefer to do this rather than simply moving for important files even if as in this case the files are being copied/movied in/to the same partition. Afterwards I checked the copied files and it reported that 13 files were bad; had a different checksum. The first 3 files appear to be contiguous files (were copied one after the other during the copy process) but I can't say the same of the rest. My big question is: What does this mean? The drive is almost brand new only one or two months of use more or less, and so far I haven't have any other issues that I'm aware** of. If I didn't have done this check I wouldn't have known or noticed there was any issue whatsoever. So far I run Scandisk in read mode: no errors.
I ran GSmartControl application to check for the S.M.A.R.T. Status.
No errors in any of the parameters as far as I can tell , and the short self-test doesn't report any errors either. Currently I'm running the Extended-Self Test. I can check with HDD Regenerator as well the drive for sector errors.
So What does this mean? Has this become a drive that I can't no longer trust and should I backup my data as fast as possible? Is it possible that more files will get corrupted without any further kinetic exposure? I've no idea about what to expect, nor what may have most likely happened and as such what can be the extent of the damage.
