![]() I keep a fairly regular check on the SMART data on my drives to try and predict failures ahead of time. The drive in question is a 3.5" 1.5TB HDD that I've had for probably close on 8 years (at a guess).Ī couple of days ago I came across something unusual which I thought might be worth sharing to see whether any SMART people (see what I did there?) might know more than I about what might be going on. It used to be an external drive but has been an internal drive in my PCS PC for the last 12 months. CrystalDiskInfo showing a caution warning for you drive and highlighting ID C5 Current Pending Sector Count Here’s what you need to know about this S.M.A.R. ![]() I use it as a media drive but there's nothing on there that isn't also in at least two other places. CrystalDiskInfo shows a caution for this drive because of the Current Pending Sector Count Value.Ĭurrent Pending Sector Count is a measure of how unstable the drive has become and is one of the key indicators of drive health. Tip: For SSD users, it is highly recommended to check the Align partitions to 1MB option. 0x05: Reallocated Sectors Count 0xC5: Current Pending Sector Count. When you click Next, it will note you that all the data on the target disk will be deleted, so make sure there is no important file on the target disk. CrystalDiskInfo reports Caution if it detects the raw value over the threshold. 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.They are apparently 'pending' until they are next read, a successful read should decrease the Current Pending Sector Count (and presumably a failed read should trigger a remapping?).Īccording to the SMART data no sectors have yet been remapped, the Reallocated Sectors Count is zero (the normalised worst value is 200), and interestingly the Read Error Count is also zero (the normalised worst value is 200), which is bizarre if I have 6 'flaky' sectors? However, the Write Error Count has been positive in the past (the worst normalised value is 149) and the Uncorrectable Sector Count has also been positive in the past (the worst normalised value is 198) but for an old drive I don't see those as a particular problem? But for the CrystalDiskInfo Caution indicator I don't see anything of major concern with this drive, especially given its age? These sectors (and I appear to currently have 6) have apparently become unstable and need to be remapped into the reserved sectors. Select a target disk as destination and Click Next. It’s unlikely that you have 100 reallocated/pending/uncorrectable sectors, you’re probably just looking at the wrong column in CrystalDiskInfo. ![]() You don’t want to be looking at the ‘Current’ or ‘Worst’ columns, you only want to pay attention to 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. 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. ![]() 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. 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. I now have 200 pending sectors and i have no idea as to what. 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. 1 Hello, I had this problem before on my E: drive (also with 200 pending sectors) and i thought i fixed it, guess i was wrong. ![]()
