But people buy them, actually store photos, and get disappointed years later. My first drive just recently reported it now has 8 bad sectors. When stores sell Archival External HDD in plastic usb box with smr archive grade seagate I cringe. These drives are useful as scratch storage - to move a bunch of stuff from one place to another or other short term needs. It’s expected that the drive will fail during warranty period (from single bad sector to total failure) with a probability that are in a low few percents - and rather hard to ignore in long term data storage scenario. Reformatting the drive doesnt repair bad sectors. Today drives are intended to be used in redundant clusters: that way its possible to achieve superior reliability at lower overal cost. I agree with the suggestions to RMA the drive theres no way it should be throwing that many bad sectors under warranty. Now – with crazy skyrocketing write densities - intentionally and by necessity not. It’s important to realize that before hard drives were rather solid. It takes time and effort to maintain backup on the external HDD, pretty much solely by means of constantly verifying data integrity until it fails and then starting over or copying back from cloud or messing with BTRFS DUP profile on single disk - amount of work to support that vastly exceed any benefit of having this flaky backup that demands attention between times it fails. (I moved the scrub discussion to a new topic to keep things focused)Įxternal HDD is better than not having it And for backup specifically - you still need offsite backup… Commercial cloud storage is always the better deal, except in a very narrow set of circumstances. It’s also very expensive considering your time investment. When it turns on, the blue light is blinkning / flashing continuosly after a whi. This is all exemplifies hidden complexities of maintaining data viability on premise. This is the behavior when a Synology NAS, in this case a DS415+, cant boot. Synology used to allow to configure the bad sector threshold when to set alarm, but IIRC it is now hard coded to 50. Select the drive you want to repair > Right-click the drive > click Properties. In the Search field, type This PC > click This PC. Option 1: Manual bad sector repair Method for Windows 10/8 Users. In more practical sense - check that found after scrub is done, and it is non-zero - RMA the disk. Method 1 For HDD Bad Sectors Repair on the Hard Drive. Without scrub (or it’s own extended smart test - which is pointless to run since scrub is a superset or they) disk can’t self-report increase in bad sector count and can just fail later seemingly out of the blue. Scrub will also as a side effect of attempting to read each sector will update disk’s reallocated sector count as reported by SMART. This is also the reason why it is recommended to scrub before making any changes to the array. However if another thing fails - like second drive, or you replace the drive to grow the pool - you don’t have redundancy anymore and will lose data. For data loss it’s necessary for failure to occur on two drives for the same block. Have I likely hosed myself for not scrubbing in 1.5 years?
