All, My ubuntu 9.1 machine seems to have a problem mounting large ntfs usb disks. When I plug the disk in dmesg says the following: [12771.531292] usb 1-5: new high speed USB device using ehci_hcd and address 5 [12771.683769] usb 1-5: configuration #1 chosen from 1 choice [12771.685552] scsi11 : SCSI emulation for USB Mass Storage devices [12771.685742] usb-storage: device found at 5 [12771.685748] usb-storage: waiting for device to settle before scanning [12776.680336] usb-storage: device scan complete [12776.685757] scsi 11:0:0:0: Direct-Access WDC WD50 00BEVT-22ZAT0 PQ: 0 ANSI: 2 [12776.686483] sd 11:0:0:0: Attached scsi generic sg3 type 0 [12776.687629] sd 11:0:0:0: [sdd] 976773168 512-byte logical blocks: (500 GB/465 GiB) [12776.691242] sd 11:0:0:0: [sdd] Write Protect is off [12776.691249] sd 11:0:0:0: [sdd] Mode Sense: 38 00 00 00 [12776.691254] sd 11:0:0:0: [sdd] Assuming drive cache: write through [12776.696240] sd 11:0:0:0: [sdd] Assuming drive cache: write through [12776.696248] sdd: sdd1 [12776.730248] sd 11:0:0:0: [sdd] Assuming drive cache: write through [12776.730256] sd 11:0:0:0: [sdd] Attached SCSI disk
But then nothing mounts. ls /dev shows /dev/sdd but never /dev/sdd1. Investigating further I opened gparted and saw there was a warning about ntfs bad sectors and a message to run ntfsresize. The output for that showed me: d...@blackswan:~$ sudo ntfsresize -i -v /dev/sdb1 ntfsresize v2.0.0 (libntfs 10:0:0) Device name : /dev/sdb1 NTFS volume version: 3.1 Cluster size : 4096 bytes Current volume size: 500105216512 bytes (500106 MB) Current device size: 500105217024 bytes (500106 MB) Checking for bad sectors ...

The disk mounts fine on my ubuntu 8.1 and on windows. My 64 bit desktop seems to be the only one with these issues. I have similar mounting problems with an ntfs formated WD drive as well. Works on the laptop, not on the desktop. Anybody have any pointers for how to resolve this? thanks, -- Daniel B.
