Hi list, can't mount my usb drive. It seems it is corrupted. I tried to run
ntfsfix and here is its ouput:

If anyone can suggest how I can recover my drive and what is exactly a problem,
I'd appreciate it. Thanks
Testdisk might be able to help.
What exactly should I be looking for in testdisk? I checked structure, it is ok. Should I do
"deeper search"? And what means "Index root attribute missing in directory inode
5"?
The problem you reported was inability to mount a USB stick. Testdisk
helps you recover from disk/file system corruption.
I suggest you use ddrescue to create an image of the NTFS partition on
the USB stick and retry ntfsfix against the image. Assuming ntfsfix
works, you can then mount the image using the loop option.
e.g. ddrescue /dev/sdx1 ./ntfs.img
ntfsfix ./ntfs.img
mkdir ntfs-image
mount -o loop ./ntfs.img ./ntfs-image
If ntfsfix doesn't work, try using testdisk against the .img file.
Once you've got your files copied to a new stick, don't use the old one.
Thanks for your suggestion. However I am afraid I can't create .img file because my
internal disk is 128 GB and my unmountable drive is 2 TB. ( it is 3'5" external
usb disk, not a USB stick ).
In that case, get another USB drive or internal SATA drive of sufficient
capacity to make the copy. Once you have a good copy that you have
verified / fixed, you can reformat the faulty drive. Do a full reformat,
not a quick one, as the full reformat verifies the disk surface and
marks bad blocks.
