Hello, list, I've tried to figure out why my external DVDRW Device has a
problem using UDF, SCSI subsystem reports "Device not ready" when burning
with growisofs, the media is being written perfect, no defective media or
sector errors ater burning. I've tried diferent DVDRW and I discover that
only pioneer has this issue DVR106D /107D/108D/109D/110D (I have a lot of
them) but only trow usb-storage or sbp2 device converters I have this
error, and with this error UDF system show bad sectors, there is not bad
sectors, and it happens only when writing big files about more than 1 or
2MB, not 100Kbyte files or many small files, Then is cause I guess the
drive need some time to get ready again and I guess scsi system can
resend the
command?!?!?!?.
Then going more far away, I see there is a black list on SCSI system,
scsi_devinfo.c that has a list of vendor and product identifications.
I've tried to add this line:
{"PIONEER", "DVD-RW DVR-106D", NULL, BLIST_RETRY_HWERROR},
With no effects, Cause this error looks like not hardware error, is just
not ready.
Then I have an Idea, what happen if on scsi_lib.c where resides the
faulty code:
if (!(req->flags & REQ_QUIET))
dev_printk(KERN_INFO,
&cmd->device->sdev_gendev,
"Device not ready.\n");
scsi_end_request(cmd, 0, this_count, 1);
return;
I change scsi_end_request(cmd, 0, this_count, 1);
by a comparison about vendor ID and Model
and then if is a buggy one executes scsi_requeue_command(q, cmd); instead
of scsi_end_request(cmd, 0, this_count, 1);
Can I use this vars to deal only the same situation and not sata, nor
usb-card reader, etc. etc.?!?!?!??!?!?!?!?
&cmd->device->vendor
&cmd->device->model
&cmd->pid
&cmd->sc_magic
How can I print it with prontk, I should use ?!?!?!
printk("Vendor: %s Model: %s Pid: %s Magic %s DevNotReady_Error\n",
&cmd->device->vendor,
&cmd->device->model,
&cmd->pid,
&cmd->sc_magic);
This device seems to require more patient to get ready...
this is my log USB-STORAGE generic adapter
