Description Ulrich Windl 2012-11-12 07:54:26 UTC

User-Agent:       Mozilla/5.0 (X11; Linux i686; rv:16.0) Gecko/20100101 Firefox/16.0

I bought a Western Digital "MyPassport" external USB disk that is preformatted with NTFS for Windows, and it contains some software on the drive. After having connected the drive to Linux, Windows reports the filesystem is corrupted, and after repair in Windows 7, some of the folders on the disk vanished.

Reproducible: Always

Steps to Reproduce:
1. Connect a WD "MyPassport" disk with preformatted NTFS to openSUSE 12.1

Actual Results:  
ntfs-3g cannot read the NTFS format, and the disk's format is corrupted

Expected Results:  
Unsupported formats shouldn't be mounted read/write. No corruption should occur.

Mounting NTFS read/write was a bad idea. Messages:

Could you please try it on openSUSE12.1?

FYI I tried  a flash disk on 12.1 it works for me .

steps:

1 formt the flash disk with NTFS, put some test files into it. reject it.
2 insert it to openSUSE12.1, open and creat some test files. reject it.
3 put it back to windows, no error

I don't understand: the "product" is opensuse 12.1!

I did not say that every NTFS filesystem fails; I said this specific one failed.

I only feel worried, because "MediaMarkt" here was selling the drive for rather cheap (and WD is not uncommon for external drives). So possibly many users will have the same problem.

Personally I solved the problem by reformatting the disk with Windows/XP and not using it with Linux so far.

Comment 3 Fan Jun Kong 2012-11-18 16:16:02 UTC

sorry, I made a mistake: it should be 12.2


So this bug only can be reproduced on your kind of disk?

Comment 4 Fan Jun Kong 2012-11-25 16:53:34 UTC

 close it . plz reopen if needed.

Comment 5 Ulrich Windl 2012-11-26 08:14:29 UTC

I was not sure: Maybe the format is special; maybe it's due to the disk having 4kB physical sectors. Sure is the format couldn't be read while the filesystem was mounted read/write.
