Hi kernel developers I don't know if this is the proper list but I have a very odd problem and it's driving me nuts for the past two days.
I have a portable mp3 player named: usb-storage: waiting for device to settle before scanning Vendor: THOMSON Model: PDP95FM Series Rev: 0100 Type: Direct-Access ANSI SCSI revision: 04 usb-storage: device scan complete SCSI device sda: 244288 2048-byte hdwr sectors (500 MB) sda: Write Protect is off sda: Mode Sense: 3e 00 00 00 sda: assuming drive cache: write through SCSI device sda: 244288 2048-byte hdwr sectors (500 MB) sda: Write Protect is off sda: Mode Sense: 3e 00 00 00 sda: assuming drive cache: write through sda: unknown partition table sd 0:0:0:0: Attached scsi removable disk sda that, I think, should act like an USB mass storage disk. I have done: # dd if=/dev/sda of=/dev/sda.dump sucessfully, several times. But I can't do: # dd if=/dev/zero of=/dev/sda The error, all the time: usb 2-1: reset full speed USB device using uhci_hcd and address 3 usb 2-1: reset full speed USB device using uhci_hcd and address 3 usb 2-1: reset full speed USB device using uhci_hcd and address 3 usb 2-1: reset full speed USB device using uhci_hcd and address 3 usb 2-1: reset full speed USB device using uhci_hcd and address 3 usb 2-1: reset full speed USB device using uhci_hcd and address 3 sd 0:0:0:0: SCSI error: return code = 0x50000 end_request: I/O error, dev sda, sector 1064 Buffer I/O error on device sda, logical block 133 lost page write due to I/O error on sda and from dd: bash-3.00# dd if=/dev/zero of=/dev/sda dd: writing to `/dev/sda': Input/output error 13489+0 records in 13488+0 records out 6905856 bytes (6.9 MB) copied, 206.473 seconds, 33.4 kB/s dd: closing input file `/dev/zero': Bad file descriptor It never stops on the same place, but is always before reaching the 7 MB. I thought that I could ajust some tuneable parameters here: /sys/block/sda/device But I'm completly lost on the problem. If anyone could be of assistance, it would appreciated.
