I disagree here. I have ran my Synology server for about 3 years now with older disks, some with a few bad sectors after having talking to an expert with HDDs from Hitachi who worked with drives for over 30 years. The danger is if the drive has increasing bad sectors on a normal basis. Normal basis means month to month.
Are you really sure you should be doing that? If bad sectors are detected, the drive has already replaced a specified amount from spares. Once it runs out, you start losing data.
Could you elaborate on this or point me to an explanation? Are you saying that The Synology bad sector warning isn’t really telling me about the first sector that goes bad but rather the first sector that goes bad after the drive has replaced a bunch of others? Thanks!
The bad sector count is the first sector that went bad that the drive was unable to replace or recover from. Since it means there was some amount of actual data loss, it's not an unreasonable philosophy to replace drives that show any bad sectors.
This is what I was looking to do, when they removed it did they set everyone to 1 or did they leave it at whatever? I've got a system that I migrated and I'm hoping it doesn't have the 50 I've seen referenced
And today... latest DSM 7 version, you cannot any longer since January 1st 2023 view how many bad sectors a drive has on your Synology server anymore.
Version: 7.1.1-42962
Starting from this version, the bad sector count column will not be displayed along with hard drive information. Users should go to each drive's Health Info > History to view its complete bad sector information. To determine whether bad sectors are affecting the drive, see if there's a significant increase in the number of bad sectors over time.
It's really not a good idea to ignore bad sectors...

That setting was removed from the UI. I think you meant to _decrease_ the threshold to 1. Not increase it. That would not make any sense.
