I've tried using it on both Mandrake 9.2 and Mandrake 10 and I see the same behavior. (I mention these two, as I believe Mandrake 9.2 uses a 2.4 kernel, while Mandrake 10 uses a 2.6 kernel and that the usb drivers changed significantly between these versions).
I can get the drive mounted just fine, and read from it without problem. I then typically attempt to dump a large amount of data to it to test writing, using nothing more complicated than cp. It gets a short way into it, and then suddenly hangs. Here's the output from my /var/log/messages file (taken from the Mandrake 10 machine):
Aug 3 16:19:33 localhost kernel: SCSI error : <0 0 0 0> return code = 0x8000002
Aug 3 16:19:33 localhost kernel: Current sda: sense key No Sense
Aug 3 16:19:33 localhost kernel: end_request: I/O error, dev sda, sector 157525
Aug 3 16:19:33 localhost kernel: Buffer I/O error on device sda1, logical block 157462
Aug 3 16:19:33 localhost kernel: lost page write due to I/O error on sda1
Aug 3 16:20:34 localhost kernel: drivers/usb/core/hub.c: USB device not accepting new address (error=-71)
Aug 3 16:20:34 localhost kernel: scsi: Device offlined - not ready after error recovery: host 0 channel 0 id 0 lun 0
Aug 3 16:20:34 localhost kernel: SCSI error : <0 0 0 0> return code = 0x50000
Aug 3 16:20:34 localhost kernel: end_request: I/O error, dev sda, sector 157526
Aug 3 16:20:34 localhost kernel: Buffer I/O error on device sda1, logical block 157463
Aug 3 16:20:34 localhost kernel: lost page write due to I/O error on sda1
These last two messages are repeated several times (though with incrementing block numbers), and then the following appears:
Aug 3 16:20:34 localhost kernel: FAT: Directory bread(block 157111) failed
Aug 3 16:20:34 localhost kernel: scsi0 (0:0): rejecting I/O to offline device
The above two messages are repeated over and over with incrementing block numbers until I kill the cp process.
Any ideas what the problem might be?
