Public bug reported: I've recently purchased a 16GB USB flash drive. Under windows it has a write speed of 5.2MB/s, however under Hardy Beta, it starts off at about 2.5MB/s after mounting, and gradually slows down as more data is copied to it, either as a single large file or as many small files, whether copied individually or in batches. I just copied a 4.4GB file to the device and it took over two hours . Copying a similar 4.4GB file to the device under Windows XP takes about 15 minutes.
After un-mounting then re-mounting, copying a 700MB file to it finishes in under 10 minutes. Each time I re-mount the device, a new folder appears under /media, which has the name of the flash drive with an underscore appended. After mounting the device, then un-mounting and re-mounting it twice, there are three folders under media, called "UbuntuStuff", "UbuntuStuff_" and "UbuntuStuff__" Description: Ubuntu hardy (development branch) Release: 8.04 ** Affects: ubuntu Importance: Undecided Status: New -- File copy to NTFS formatted USB device very slow https://bugs.launchpad.net/bugs/213995 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
