ddrescue - Recovering 16GB MicroSD

Thanks! 馃檪-聽I will stop ddrescue and give both PhotoRec & TestDisk a try!

I just thought that ddrescue were better to rescue/recover bad and/or corrupted files.

When it takes more than 2 days, you should start to question its reliability.

I have a bad 16GB MicroSD card, where I could read a small amount of its files. (Photos, Video etc.,)
I ran ddrescue --retry-passes=3 /dev/mmcblk0p1 which saves to an .ISO and .LOG-file on my USB3 SSD hard drive.
It have now been running for over 19 days and 2 hours.
Where last successful reading, were 13 days and 15 hours ago.
For the past 10 days, i think, it have been "scraping failed blocks... (forward)"

(1,64% rescued)

Is that really normal, for only 16GB ??

Should I just let it run or would you guys stop it?

How full was the card before being corrupted? Thats imo way too long, considering that I've rescued maybe 4gigs of files off USB3 stick. I used PhotoRec/TestDisk https://www.cgsecurity.org/wiki/PhotoRec

Thanks for the reply!聽馃槉

I actually don't know, since it comes from my dads phone.
I just wanted to rescue as many pictures as possible, since he didn't had a online solution (till now).


Can TestDisk recover files, when it's corrupted?
I have only used it to get back "normal deleted files or partitions".

But I also think this takes too long, since I can rebuild a 4TB RAID1 within two days.
(I know this is MicroSD and USB, which isn't as fast as SATA3...)
Actually, I just saw that the laptop only have USB2......聽馃檮

I would have given it one day, tops. -聽Especially for only 16GB.
But since I did a three times retry, I聽accepted that it could take longer time.
But 19 days is a bit too much.....聽馃檮
Even that it have been through multiple stages.

Thanks for the help with my adblocker @LoGiCalDrm! 馃檪
I just wanted to show the process of the ddrescue, before I stopped it and tried聽the other solutions you guys came with.

##### UPDATE:

I've just started PhotoRec, which seems to a lot faster with only 8 hours, rather than the 20 days ddrescue were running on...聽馃槄

... and now after about 8 hours, it couldn't find any files and continues the search:

So I think the MicroSD is done and I should only be happy about I even can read the small amount of files i could from the beginning.聽馃槄
