How to save data from a drive?

Anonymous Sun 07 Sep 2025 03:46:49 No.1539627 View View Reply Original Report

Chatgpt just gave me a command that overwrote an external drive of mine. I started it before reading.
I just wanted to test the speed and check if the drive is ok bc there was an error before. I aborted after a few seconds but the drive still doesnt show up anymore.
tried photorec for recovery but it only gives out unreadable trash. Any possibilities I get the files back?

You overwrote sde with sda, that means you overwrote the partition table, boot sectors and whatever data was there until you stopped. The data itself after that is still there, it's just not normally accessible anymore.
It's like you took a book an ripped out the table of contents, the pages are still there, but the index what is on which page is gone. Except your book as a few milion pages.

dd is like a knife. Very powerful and can fe extremely useful, but you gotta know how to use it. You can either cut an onion or stab your heart.

and is there any way to restore that? I used a backup program but it only gave out gibberish. 180 directories full of mostly text files. And the contents are mostly things I dont need.
Text searching stuff I cant find what Im looking at.

I'd try restoring the table with TestDIsk an then try writing a new boot sector.
But before that I'd copy it over - with dd, ironically - and ONLY work on the copy.

Never try writing restoration operation on the original, always make a 1:1 copy first.

That depends if you took precautions such as:

--- Storing all parts of each file in order --> if free space is contiguous, a file's sectors are written in the order it was received. Thus the pages of your book (that is missing the list of contents) are in order. Otherwise, all the pages are mixed up (out of order) and that means reading all the datablocks for EOF markers is not the singular easy cure.

--- Kept all files contiguous. --> If you frequently defragged to keep both files AND empty space contguous, then chances are better that all pieces of your file are adjacent to each other. You can look for EOF markers and read them out to a different drive as File001.ext, file002.exe, file003.ext, etcetera. I've done that before and then examined each file and renamed them manually based on what I found.

TESTDISK and other partition+file repair tools can help. Of course, you probably asked ChatGPT how to either reverse or recover from that command, right? Did it tell you to use Testdisk or a partition+file repair tool?
