Invalid file signature error? #4

Open elsorino opened 4 years ago

elsorino commented 4 years ago

What causes this error? I attempted to use this to convert a 2TB hdd but it gave me that error. On arch linux if that matters

lideming commented 4 years ago

Same, also on Arch Linux, when I was trying to convert a Windows 10 OS drive.

Just searched in source and found the line that throws that error: https://github.com/maharmstone/ntfs2btrfs/blob/171e9b92114ca08207afc34ccb190b4a9dfd90fb/src/ntfs.cpp#L75

Essentially it means "I've opened something that should be a file but isn't", which isn't very helpful. It looks like the program could do with being tested against more filesystems...

Same error on a 500gb hdd run on Ubuntu 20.04

ghost commented 4 years ago

Same here, actually, Manjaro. REALLY hoping to try this out on my "VR Only" Windows installation for giggles.

Same issue on my 2TB SSD. GDB trace:

If running in Windows, the program will exit without any output, but the file system is not converted.

Sector signature is 0, the entire block buffer is 0. Could be an empty block or a corrupt block? I have this error as well, CHKDSK says the disk is fine. Might be an issue relating to fragmented disks / SSDs and empty blocks.

Program exiting without input is an issue relating to stderr flushing, should be fixed with my PR #5

Mine IS on an SSD now that you mention it

Reproduced on a 512GB NVME SSD.

TheGlitch76 commented 4 years ago

I've looked into it further, and it appears that the underlying issue is that (as of Windows 10 build 2004) the Windows installer picks a cluster size of 512kb for partitions on an SSD. The README states that Ntfs2Btrfs only supports cluster sizes of 4096kb. It seems that for now a workaround would be to manually create the partition and give it a cluster size of 4096 when installing.

timawesomeness commented 4 years ago

There must be multiple underlying issues causing this error then, because I'm experiencing it on an HDD with 4096 cluster size.

maharmstone commented 4 years ago

Could you give it a go on the latest version please?

@TheGlitch76 - that's news to me, are you sure about that? There's nothing on https://support.microsoft.com/en-gb/help/140365/default-cluster-size-for-ntfs-fat-and-exfat, which says that Windows only chooses sizes other than 4KB on really massive disks. https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-fsa/4e3695bd-7574-4f24-a223-b4679c065b63 was updated a week ago, and nothing there either.

I now get "Error seeking to ffffffffd781c000" when pointing it at my Windows partition.

hrm, I was probably measuring something other than what I thought (found it with linux commands). Either way, it's getting past that now, but still failing. Here's a log, but I think the issue may be that the drive is nearly full. I'll have to do some reorganizing of my partitions and try again with more space.

maharmstone commented 3 years ago

Have you tried doing as it says - running chkdsk and trying again?

TheGlitch76 commented 3 years ago

Yes, running chkdsk showed no errors, and a fresh install with sufficient space is giving the same issue.

maharmstone commented 3 years ago

Is this still an issue on today's version?

alucryd commented 3 years ago

Is this still an issue on today's version?

Yes sir, on version 20210105: Invalid file signature (00000000, expected 454c4946)

Edit: This was tested on arch linux, I'm happy to provide any useful additional information.

embedvr commented 2 years ago

I am getting this issue on my 8TB hdd on Windows 10 (21H2) Invalid file signature (00000000, expected 454c4946).

Edit: Got it again on Fedora 36, same drive.
