WD TV Live corrupt data on external NTFS drives when using sparse files.
How to reproduce problem:
Connect external drive to WD TV Live (Firware version 1.01.24)…
Map this drive to local PC via LAN.
Create some sparse files on drive. Total files size must be more that whole drive capacity.
Then contynue write data to these files.
Sooner or later you will get the write error.
File system will be corrupted, even if it still be possible to read/write files.
(Funny thing: Some directories will be listed twice)
chkdsk on Windows will fix them, byt some files will disappears, and some will be truncated to zero.
The easiest way to create sparse files is using uTorrent program to download some lardge files from Internet.
Do not try to write to drive more data, that whole drive capacity.
