If you write '1111' into the sector, and it reads back '1010', obviously it IS bad, and it will be relocated to a spare good one. Usually when you write into those sectors would the drive know it's actually bad or not. Same as 'pending' meaning they are waiting to be reallocated but whether the drive actually reallocates them is still unknown at the moment. It also could be that the sectors used to have incorrect data and thus cannot represent meaningful data. It could be that the sectors are actually dead. All we know is that the 76 sectors are not correctable, meaning that the data was successfully read but cannot pass the checksum test. Now, you may ask, are those 76 sectors 'bad'?Īctually, we can't tell. They are exactly what they are: You have 76 sectors that are uncorrectable (note the wording) and are pending to be reallocate.

But they are not equivalent to issues themselves.įor example, C5 and C6 are pending and uncorrectable sector counts. SMART could indicate issues within drives. They are reliable as what they are, and not reliable as what they are not. Is the SMART status free from tampering? (if I format the disk will it 'reset' the status?)Īny thoughts or comments are appreciated.

Is SMART an end-all-be-all indicator regarding if a drive is failing? How 'dynamic' is the SMART status? (went from 76 to 128 seemingly minutes) I am currently backing off everything on there So then I did some googling, read the Backblaze article about SMARTĪfter having the drive plugged in for a couple of hours just idling, I check the SMART status in CrystalDiskInfo, the warning for Reallocated Sector Count when from amber back to blue.Īnd now both my C5 and C6 are 76.actually, at the time of writing this post, it became 128. With ID 05, C5, and C6 on amber, I had 16 Reallocated Sector Count, and some 36 for both C5 and C6 I plugged it back in and check the SMART status, sure enough, it became Caution Literally yesterday, it showed the status being Goodīut today, after accidentally unplugging it from my computer (while not transferring any file or reading anything) without doing the eject option in Windows. So I have a Seagate Backup Slim drive (ST2000LM007) and it seems to be failing (?), but I am not so sure after constantly checking CrystalDiskInfo. Excuse me for going straight to the point.

Crystaldiskinfo check smart status
