| 05:15:52 | <atphoenix> | Doranwen, look up ddrescue. It is effective at creating dd images of flakey source devices. Unlimited retries possible. For media preservation, look up the aaru data preservation suite |

| 05:47:27 | <Doranwen> | atphoenix: Thanks for the tip. I'll have to try that this weekend if I can. I really need to get an image of this drive made so that I can replace it if the hdd fails. I've got stuff installed that I can't replicate and I really don't want to lose it. |

| 05:54:37 | <atphoenix> | ddrescue is definitely your friend here. As long as you can get the drive to be seen on Linux, and it's somewhat readable, ddrescue will read everything that is quick to read, and then it'll loop back and start retrying the problem areas. I've had drives where the tool eventually somehow read the failing sector after IDK how many dozens or hundreds of tries. |
| 05:55:31 | <atphoenix> | I'm guessing what happened is the drive's own error correcting codes in combination with the data retrieved from the sector were enough for the drive to say 'here's what you asked for' instead of 'sector error' |
| 05:55:46 | <atphoenix> | (on the successful read) |
| 05:57:01 | <atphoenix> | the other tool, aaru, is neat in a similar way. It can do rereads on removable media, and let you merge multiple identical source media that each may have corruption in different places. |
| 05:57:53 | <pabs> | is this the aaru you mention? https://github.com/aaru-dps/Aaru |
| 05:58:42 | <atphoenix> | I haven't tried aaru on hard drives. I think I've tried ddrescue on removeable media. There is some overlap in functionality, but AARU is specifically designed for data preservation. ddrescue is designed for recovery. |
| 05:58:44 | <atphoenix> | pabs, yes |
| 05:59:26 | | pabs wonders if it works on Linux |
| 05:59:30 | <atphoenix> | yes |
| 05:59:43 | <atphoenix> | multiplatform |
| 05:59:48 | <pabs> | nice, I saw .NET and thought it must be Windows-only |
| 06:01:55 | <TastyWiener95> | .NET does indeed run on Linux believe it or not |
| 06:02:35 | <JTL> | MS got tired of dealing with Mono? /s |
| 06:02:45 | <@JAA> | It's even packaged on some distros these days. |
| 06:02:51 | <@JAA> | And yeah, Mono still exists as well. |
| 06:04:01 | <atphoenix> | claunia has an IRC channel on Libera.Chat #aaru |
| 06:06:08 | <atphoenix> | FWIW, there are at least 2 different ddrescues. ddrescue at https://www.gnu.org/software/ddrescue/ and and dd_rescue http://www.garloff.de/kurt/linux/ddrescue/ |
| 06:08:30 | <atphoenix> | https://en.wikipedia.org/wiki/Ddrescue I'm not sure whether one or the other is better for some jobs vs the other. It's good to have alternatives. |

| 15:11:33 | <atphoenix> | ++ on the mapfile/logfile. It's also useful in case it is desireable to combine ddrescue with other filesystem repair or carving tools to identify what file(s) may have been affected. If the sectors with read errors are unallocated space or related to deleted files or easily replaceable files, the importance of trying to reread them diminishes |
