I got the similar messages when using Seagate FreeAgent USB drives which spin down their disk after 15 minutes of inactivity by default. In /var/log/messages, above these these ntfs errors kernel: sd 5:0:0:0: [sdc] Device not ready: <6>: Sense Key : Not Ready [current] kernel: : Add. Sense: Logical unit not ready, initializing command required kernel: end_request: I/O error, dev sdc, sector 6291527 kernel: Buffer I/O error on device sdc1, logical block 786433 ntfs-3g: ntfs_attr_pread: ntfs_pread failed: Input/output error ntfs-3g: Error reading $Mft record(s): Input/output error ntfs-3g: ntfs_mft_record_read failed: Input/output error Since an Input/output error (I/O error) is normally an indication of a problem actually doing the read/write operation on the device, it sounds like you should also check the kernel logs for any USB or SCSI errors like those I got. While I am not aware of any linux kernel issues with LACIE Big Disk USB 500GB drives, but I thought I'd tell you that you should look there as well. The command 'dmesg' shows you the latest messages which are logged by the kernel. The problem with the Seagate FreeAgent USB drives will hopefully be solved for all future with the next upstream kernel release (2.6.24), at least a fix which enables USB disk startup in case it is not ready was in GregKH's patch list for the new kernel the last time I saw it. If you see kernel errors, you can also try a newer kernel (at your own risk), and the fix for the Seagate FreeAgent USB is to automatically enable extended SCSI error recovery by setting "allow_restart" (can also be set thru sysfs) for all USB disks. It causes that USB disks which are not ready for I/O can be tanspartently started up when they are accessed thru the kernel's SCSI layer.
