I have a computer which is almost 10 years old now. It uses a hard disk which is also almost 10 years old. Recently I had installed a software called 'Hard Disk Sentinel' which checks the health of the hard disk. The software told me that that the health of my hard disk was 14%. It said:
There are 528 bad sectors on the disk surface. The contents of these sectors were moved to the spare area. 4089 errors occurred during data transfer.
In case of sudden system crash, reboot, blue-screen-of-death, inaccessible file(s)/folder(s), it is recommended to verify data and power cables, connections and if possible try different cables to prevent further problems. It is recommended to examine the log of the disk regularly. All new problems found will be logged there.
It is recommended to backup immediately to prevent data loss.
But my computer is almost 10 years old and I have not had any data loss whatsoever. All my photos, videos and documents are there in their respective disks and all open and run smoothly. As a matter of fact it's been 3 weeks now since I scanned my hard disk and found out there were bad sectors and still there has not been any data loss.
Should I be worried by about my hard disk and if so why has not there been any data loss in my hard disk?
P.S.: All of my drives other than Local Disk (C:) are HDDs and their health is being shown as 14% and all the stuff which the software is saying is about those HDDs. However my Local Disk (C:) is an SSD and it's health is 100%. It has no problems.
