@ Luis (#198): can you please post/link to the changes made to fstab? I have no lines in fstab for USB drives, as DeviceKit is supposed to take care of that.
@everyone having problems and still following: how many of you tried to bypass the filesystem by using dd or hdparm -t? Running Karmic amd64, I'm having ridiculously slow speeds just reading from 3.5" HDD over USB (in the 3-8 MB/s range), right after bootup, using hdparm -t or dd'ing from to /dev/null: $ sudo dd if=/dev/sdb of=/dev/null count=1024 bs=32k 1024+0 records in 1024+0 records out 33554432 bytes (34 MB) copied, 7,03421 s, 4,8 MB/s $ sudo hdparm -t /dev/sdb /dev/sdb: Timing buffered disk reads: 18 MB in 3.29 seconds = 5.47 MB/sec Hardware is Intel ICH8, the same gives me over 12MiB/s in Windows NT 5.2 and Hardy i386. The hard drive puts over 40 MiB/s over ExpressCard->eSATA Silicon Image SiI 3132 ** Attachment added: "dmesg.log" http://launchpadlibrarian.net/35947788/dmesg.log -- file transfers on USB disk are very slow https://bugs.launchpad.net/bugs/197762 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is a bug assignee. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
