ntfs-3g i/o errors writing large audio files to usb hard drive

when copying files from internal hdd formatted ext3 to usb 2.0 500GB seagate hdd formatted ntfs (automagically mounted in /media as writable using ntfs-config):

1. 100% cpu usage (constant until file transfer is killed)

2. extremely show file transfers (time remaining 2.5-3 hours for transferring 280MB of flac, mp3, shn, and ape audio files; time remaining 10.5 hours --and climbing-- for transferring 3.1GB of isos; 15 sec to transfer 730KB) when copying or moving files onto the ntfs volume

  -large file transfers (that take 4-8 hours overnight) fail giving an I/O error message

3. unable to eject or unmount the usb 2.0 external hard drive with nautilus, only a sudo umount works. even sudo umount /dev/sdb1 fails, saying device is busy. sudo umount /media/<hdd-name> gets rid of the desktop icon, then sudo umount /dev/sdb1 works.

  -the first time i 'ejected' the usb device, it seemed to start working. then a message popped up from the bottom right of taskbar saying something like the usb device can now be safely removed. this was followed by another pop up saying not to unplug the usb device because something still needs to be written to the disk.

4. once unmounted from cli, after unplugging the usb cable and replugging the usb cable back in, the hdd is not automagically mounted.

5. hdd did automagically mount after power cycling the hdd and then plugging it back in.

From ntfs-3g upstream: the I/O problems are related to Seagate devices and are file system independent. The reason and a potential workaround is discussed here: http://www.nslu2-linux.org/wiki/FAQ/DealWithAutoSpinDownOnSeagateFreeAgent

The problem is in the Linux kernel (USB driver, etc).

It happens not only with Seagate but also with Maxtor USB HD drive
have a nice day

[Szabolcs Szakacsits (szaka)]

Yes, it can happen with any disk which powers down during write activity, have bad sectors or other hardware fault.. You can find the proofs in the logs under /var/log/ There isn't absolutely anything ntfs-3g could do about such problems besides reporting them. They are on a lower level.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with latest Ubuntu release? Thanks in advance.

[mongo (mongio)]

no more an issue for me, this bug has been fixed out in newer ubuntu releases. Thanks and have a nice day
