dd is a beautiful little swiss army knife and I'm not ashamed to be part of the "cult" lol. I have had to use ddrescue too though. It's handy to have in the toolbox if you have a disk with errors and want to get data off of it.

Sorry, you're right, I definitely meant ddrescue. That's what I always use, no idea why I wrote dd. Especially since ddrescue -d -n -S /dev/sdb sdb.raw sdb.logfile is permanently burnt into my brain. I guess I just took it from the previous comment and article and didn't give it a second thought before posting my comment.

One of the charms of dd is its hilarious syntax. And, used properly, it's a bit of a swiss army knife for a few different disk operations.

To me `dd` stands for "destroy disk"

Ddrescue is awesome

ddrescue on the other hand is completely worthwhile

ddrescue is excellent.

I use ddd.

Huh? I've always used dd and the performance seems quite acceptable.

I know what `dd` is. I just don't use Linux, so I'm not particularly familiar with the Linux-specific /dev entries. Thanks though.

For linux there is always DDD

Yep, every couple of years I need to use dd. Never knew of an alternative to sda.

I've been taught at my uni to use dd...

I'm fond of ddrescue, and I'll note pv could have replaced cat in one example.

ineedasername | karma 21111 | avg karma 2.94 · | 2023-09-22 05:50:54

What’s dd?

cat199 | karma 1610 | avg karma 0.77 · | 2017-03-29 19:54:06+00:00

Didn't you hear? dd is a 'cult', and you should use 'standard' commands like pv instead, so this is totally okay, in fact good.

Use something other than DDD?

_joel | karma 2846 | avg karma 2.1 · | 2021-06-16 14:11:45+00:00

Depends which dd you use and what version.
