We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

A number of bad sectors on hdd in one day, how bad is it? (alien.top)

HDD worked flawlessly so far, it's an old hdd from like 2014, crystal disk info and hdd sentinel both showed good health.

Then a couple days ago pc started behaving weirdly, it didn't recognize my 2nd ssd that was bought about a month ago, then after a couple reboots it recognized all drives just fine, then today I had a couple of boot sequences where a part of the os didn't even initialize or something, icons were missing, tabs in the browser were missing, crystal disk info couldn't even load, showed something like "software doesn't fit your system".

Then after another couple reboots and fiddling with sata connectors and power connectors inside the case, making sure all is plugged in well, system starts normally again, but the videogame I played just yesterday won't load (it's on that HDD). Opened crystal disk and sentinel again, both show that HDD went from 100% to 80% in one day and acquired a number of bad sectors (says 8). HDD sentinel graphs show rapid decline in one day.

How come a perfectly good drive just goes bad like that in a day?

If the number of bad sectors is a multiple of 8, the software is probably counting logical sectors of 512 bytes each, while the disk has physical sectors of 4096 bytes each. Each time a physical sector fails, the software counts it eight times.

Still worth replacing the disk -- a functional disk shouldn't have any bad sectors.
