Who are we?

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). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

We are one. We are legion. And we're trying really hard not to forget.

So i'm testing one of the drives I got on amazon using an old computer. It started off promising, didn't get any errors when formating the drive, write speed using a usb adapter at 25mb/s... Then it dropped off to 7mb/s and the expected time shot up from 40hours to 156h๐Ÿคฃ

I'm going to let it run over night and see what happens in the morning. If I can get it to show 4tb without error I might still keep them to test out my geekworm pi nas, otherwise back to amazon you go!

There is some software you can get to check for bad blocks and then mark them do not write. This will allow you to salvage as much of the drive as possible. I recently got a dead 4tb drive fully restored and working. I hope you are as lucky!

This usually isn't a thing on SSDs.

[โ€“] Auth@lemmy.world 1 points 11 hours ago (1 children)

It is. The SSDs have two methods of managing this. The first is to simply skip the bad block. The second is to replace the badblock address with a good block from the SSDs reserve block storage. This is all done by the SMART controller in the SSD.

This is correct, but it doesn't require manual intervention by the user.

Sorry, I don't think I worded that properly, these are mew drives I got off amazon, 4tb for $65 each. i'm running a test to see if they're any good or pure garbage using an old computer at work ๐Ÿ˜…

[โ€“] Auth@lemmy.world 11 points 1 day ago (1 children)

Oh then you're cooked. Those are 100% scam drives.

Probably, I was just hopping amazon made a mistake on the price or something ๐Ÿคช

LOL

You could buy 20 of them and make a RAID. So their cache sizes add up, and the total crawl speed as well ๐Ÿ˜†
