Error: [0xC0030570] The file or directory is corrupted and unreadable

I have tried several flash drives that I know are good

But did you run an actual bad blocks check from Rufus?

It's not enough to "know" that your drives are good. You need hard concrete evidence that they are, which can only be accomplished through a bad blocks check that also tests for fake drive, like the bad blocks check of Rufus.

[pbatard]

Why would rufus work fine with the flash drive when I do not have any persistence?

Because persistence accesses pretty much all of the range of the drive in terms of sectors (due to the ext formatting of the ext partitions, with inodes being created all over the place).

When not using persistence, only the beginning of the drive is accessed. So, if you happen to have a fake drive with an actual capacity that is larger than the size of your ISO (as opposed to the fake reported capacity, which will be much larger than actual), then everything may look good because you're not trying to access sectors past actual capacity. But persistence will try to use all of the drive, so that's precisely when failures are expected to occur, as you will be writing sectors past actual capacity.

At any rate, just test the bloody drive for bad blocks. It's not that difficult and it's the ONLY way to be sure that your drive is good. Anything else is just speculation.

If your 2 TB flash drive's price was too good to be true, then it's probably fake... These go for at least $100 (as they should), and you can be darn sure that all those cheap 2 TB flash drives you can see for sale on aliexpress, that are priced around $10 or less, are 100% fake.

[pbatard]

Actually purchased on eBay.

Not much of a warranty that it'll be better than aliexpress. Same unscrupulous sellers operate in both spaces, and since you did not talk about how much you paid, I'm going to assume that it was way less than $100.

a 64gb sandisk I purchased at Walmart

Not much of a guarantee either. People have gotten fake drives from Walmart. I know. Because some of them complained that Rufus didn't work properly, and when they did run a bad blocks check, they found that the drive was fake.

Now, again, until you do report with the results of your bad blocks check for both drives, this is just pure speculation on my side, since I still don't have any hard evidence to go by...

Damaged USB drive likely.

[KireinaR]

Damaged USB drive likely.

All 3 of them? Likely not.

This seems to be a sporadic issue reported by some people and which appears to have to do with Windows not liking "foreign" file systems being created.

Unfortunately, this is not something I can replicate, which makes it exceedingly difficult to try to investigate.

I would appreciate if you could post a log with the results of a bad blocks check, as some people got this issue on defective drives (and you may have connector issues rather than bad drives, which would explain repeated failures with multiple devices).

Sure I will run a bad block check.
Update: I tried it on a different computer and got the same result.

[KireinaR]

I guess there are bad blocks. Any ways to fix ?

No. Change your drive(s). And be mindful that some unscrupulous vendors out there will sell fake drives (i.e. drives that have been tampered to show a larger capacity than they actually have, and that will fail when you try to access blocks beyond the capacity), so please be also mindful of cheap drives.

As your issue was external to Rufus, I will now close it and advise anybody encountering these kind of errors not to pay "lip service" to the check list, that explicitly asks you to run a bad blocks check, but to actually do it.

[thecatontheceiling]

your usb drives are probably fake, bad blocks check results are suspicious

[KireinaR]

Thanks so much guys. Appreciate the help, I will buy some new drives then.

I am having the exact same issue. I have tried several flash drives that I know are good. I have tested flash drives after using diskpart. The drives work fine but when using rufus I get to about 40% through the format process before the error pops up.
"Error: [0x00305570] The file or directory is corrupted and unreadable."

I am using a 2 tb flash drive so this may take some time.

[N5SLI]

Actually purchased on eBay. but the second drive I have is a 64gb sandisk I purchased at Walmart and it has the same issue.

Sorry for taking so long to get back to you. I am a 2-way radio technician and have been really busy lately. You were correct, there were many bad blocks found. Thank you for explaining things too me. I appreciate you taking the time to explain how persistence works. Have a great day.

[Mrsaucejunior]

There is no bad blocks for mine but it is still showing same error
Or is there any other way for checking bad blocks?
