Using 2.6.17.11 on a Debian Sarge system. I have a brand new external USB 2.0 250GB hard drive. It shows up like this:
Vendor: WDC WD25 Model: WD-WMAL71747150 Rev: 2D08 Type: Direct-Access ANSI SCSI revision: SCSI device sda: 488397168 512-byte hdwr sectors (250059 MB) sda: Write Protect is off sda: Mode Sense: 00 38 00 00 sda: assuming drive cache: write through SCSI device sda: 488397168 512-byte hdwr sectors (250059 MB) sda: Write Protect is off sda: Mode Sense: 00 38 00 00 sda: assuming drive cache: write through sda: sda1 sd 0:0:0:0: Attached scsi disk sda It mounts fine and works for a while. I've run badblocks on the drive several times with no bad sectors detected. After a day or two of use (attempting to do a large rsync backup nicely so it doesn't interfere with server operations), I get the following type failures: usb 4-1: reset high speed USB device using ehci_hcd and address 2 usb 4-1: device descriptor read/64, error -71 usb 4-1: device descriptor read/64, error -71 usb 4-1: reset high speed USB device using ehci_hcd and address 2 usb 4-1: device descriptor read/64, error -71 usb 4-1: device descriptor read/64, error -71 usb 4-1: reset high speed USB device using ehci_hcd and address 2 usb 4-1: device not accepting address 2, error -71 usb 4-1: reset high speed USB device using ehci_hcd and address 2 usb 4-1: device not accepting address 2, error -71 usb 4-1: USB disconnect, address 2 sd 1:0:0:0: scsi: Device offlined - not ready after error recovery sd 1:0:0:0: SCSI error: return code = 0x10000 end_request: I/O error, dev sda, sector 315743839 sd 1:0:0:0: rejecting I/O to device being removed sd 1:0:0:0: rejecting I/O to device being removed sd 1:0:0:0: rejecting I/O to device being removed Buffer I/O error on device sda1, logical block 39468062 lost page write due to I/O error on sda1 sd 1:0:0:0: rejecting I/O to device being removed last message repeated 17 times Buffer I/O error on device sda1, logical block 24510578 lost page write due to I/O error on sda1 sd 1:0:0:0: rejecting I/O to device being removed etc.. After that, it is no longer possible to read or write to the mountpoint. I also can't remount the drive -- even restarting hotplug it appears that a full reboot is necessary. Any ideas how to isolate the problem? I can't figure out if it is a hardware or software problem. I did a large transfer to and from this drive on another system without problem. The results above on the system in question seem reproducible, at least inasmuch as they keep happening after a couple of days of use.
