This is all transparent to the outside world - except for the SMART util.Įach manufacturer can do as they please, so some set the error counts to zero, even though there might be 10 bad sectors as soon as the drive is manufactured. In fact they are "logically swapped out" - the bad sector is mapped to a new, good, spare cylinder sector (it has spare cylinders - think of cylinders as tracks). So they map them out, this means the drive skips bad sectors.

In the olden days, we had to enter the bad sectors in to the HDD controllerįrom a list on paper that came in the new drive box, so the controller skips them. There is no perfect HDD, never was, never will be, (history and fact). You will see how HDD's are made, tested and how they really work.

This is less than 41, so its health score remains at 100.If you read the data sheets (white papers) say at

So that means that the drive loses 1 point for every 41 sectors (= 1716 / 41 ).ĭrive D: has recorded 16 (= 0x10) reallocated sectors. This means that it has lost 41 points (= 100 – 59). If we take drive F: as an example, we see that it has developed 1716 (= 0圆B4) reallocated sectors. When this score drops below the threshold, the drive is considered to have failed. When the drive begins to develop bad sectors, the health score declines.

These particular attributes begin life with a health score of 100%. Am I reading this incorrectly? The raw values show a difference though.Īnswer:ISTM that the OP is having difficulty understanding the normalised values of each attribute (Current / Worst / Threshold). Looking at the data from the program it looks like the Current and Worst for Reallocated Sectors Count, Current Pending Sector Count, and Uncorrectable Sector Count are the same from the Primary Data drive (D) to the Primary Backup drive (E) but D is flagged as Caution. My primary data drive and secondary backup drive are showing Caution, but I am having trouble understanding the results as the results appear to be the same between my primary data drive and my primary backup drive but one shows caution and the other shows good. Question: I recently felt my computer was running slow when accessing data on the hard drives and the data on the hard drives was getting slower to populate so I decided to run some health checks and ran CrystalDiskInfo to check my hard drives out.
