Pending sectors are a warning sign that your drive may experience some problems or failure. The pending sector count can go up/down depending on whether or not the drive can later successfully read data from the sector, or if the sector is bad it will become a reallocated sector (ID 05) and the pending count will decrease but the reallocated count will go up. Your Current Pending Sector Count is a warning about unstable sectors on your drive that are waiting to be remapped (reallocated) to spare space on the drive.īasically, your hard drive had trouble reading a sector of the drive and it is considering remapping the sector to one of the spare sectors. CrystalDiskInfo C5 – Current Pending Sector CountĪ number greater than 0 in the C5 – Current Pending Sector Count column will cause CrystalDiskInfo to set off a Caution warning. There are 3 common errors that will set off CrystalDiskInfo to issue a warning about your hard drive’s health, so let’s jump into these and figure out exactly what each one means. This will give you the actual number of each column instead of gibberish only robots can read by memory.Ĭommon CrystalDiskInfo Data Points That Should Give You ‘Caution’ It can sometime show by default as a hexadecimal value (letters and numbers) and that’s not very helpful unless you can convert Hex to Decimals in your head, if you’re not a robot then you can change this by going to:įunction -> Advanced Features -> Raw Values inside of CrystalDiskInfo and setting it to ’10 DEC’ to get a decimal output for the Raw Values column. The ‘Raw Values’ column is the actual number of errors that your drive is detecting for that S.M.A.R.T attribute. You don’t want to be looking at the ‘Current’ or ‘Worst’ columns, you only want to pay attention to the ‘Raw Values’ column. It’s unlikely that you have 100 reallocated/pending/uncorrectable sectors, you’re probably just looking at the wrong column in CrystalDiskInfo.
You’ve just opened up CrystalDiskInfo and it’s showing an amber Caution warning next to one of your hard drives, now what do you do? Is your hard drive about to crash? Do you need to replace your hard drive right away? Are things really that bad/can I keep using the drive?īefore we dig into what each S.M.A.R.T data point means, I need to address a common error I’ve seen online:
