Device not ready
by Paulo José da Silva e Silva 25 Feb '02

25 Feb '02

Hello, I am using kernel 2.4.17 with the corresponding packet writing patch. When I try to move big files to the cd I get a bounch of error messages like this: device 0b:01 not ready: cmd=0, sector=9864, nr_sectors=120 Anyhow the files seem to be OK at the end. Although, once the kernel hang and I had to reboot. Is this a known problem? Is there something I can do to avoid these errors?

Re: Packet Writing on RedHat7.0

Hi, Now I have dowloaded Linux-2.4.17 and corresponding patch for packet writing from http://w1.894.telia.com/~u89404340/patches/packet/ and compiled. (included udf support) After that downloded udftool udftools-1.0.0b2.tar.gz and compiled. Loaded the following modules usb-uhci.o,usb-storage.o,sg.o,cdrom.o,sr_mod.o,udf.o, pktcdvd.o Then Used 'cdrwtool -d /dev/scd0 -q' to setup the cd-rw media. (HP CDRW 650 MB media on HP8200a) While formating the cd-rw media usb timeout message are displayed and after a while a kernel panic occurs, something like 'Aiee, cannot handle interrupt.. due to a null pointer dereferencing is occuring in usb.c code. Would be of great help if someone who has successfully tried packet writing gives stepwise input.

Hi Everybody, I have installed RedHat Linux-7.0 with Kernal version- 2.4.0 .. I want to configure my Linux for packet writing...I have downloaded packet-0.0.2d.tar.gz and udftools-1.0.0b1.tar.gz. I compiled the kernal and tried to installing udftools... It is not compiling and giving error.. I wanted to know that whether I can configure RedHat linux for packet writing or not?? If yes then what all tool and patch I require for RedHat-7.0 Kernel Version-2.4.0.. Thanks Suman ===== ----------------------------- Shailendra Kr.

How to use a Panasonic LF-D101 DVD-Ram with Suse7.3
by Dietrich Restemeyer 12 Feb '02

12 Feb '02

The subject allready tells everything. The DVD Ram is an 2,6 /5,2 GB one. SCSI. Different to my Panasonic PD Drive which is listet with two LUN 0=cdrom 1= optical device, the DVD-Ram LF-D101 is only listed with one LUN device type =cdrom. Anyone out there who can tell me this behavior is right? How can I use this DVD-Ram with SuSE Linux 7.3 ?

Re: New cdrwtool (trying to format too many blocks)

This error message happens when the kernel asks the packet driver to write an incomplete packet. In that case the driver first has to read the missing part of the packet from the disc, and then write the whole packet back to disc. If the read fails, this error message is printed, and the packet driver has two choices, both bad: 1. It could skip copying data to the disc. 2. It could copy the new data to the disc, even though it doesn't know how to preserve the old data. (because reading the old data failed.) The packet driver currently chooses the second alternative, but that's not the problem. It would be equally bad to choose the first alternative. The real mystery is why the read fails. I have seen some drives reporting "device not ready, long write in progress" when you send them a read request while they are writing a packet. However, the packet writing patch includes modifications in the scsi layer to handle this case and retry the read request until it succeeds. If you are using an ide cdrw without scsi emulation, this retry logic is not being used, but with scsi emulation (which I think you are using) it is used. Maybe the read requests can fail for other reasons that are not detected by the scsi layer retry logic?

Just make sure that this value is not larger than the maximum write speed supported by your drive/disc. -- Peter Osterlund - petero2(a)telia.com http://w1.894.telia.com/~u89404340

This value is not used at all, so changing it has no effect in the 2.4 version of the packet patch. I think I will remove it from the next patch to avoid confusion. The 2.5 version does use this value, but I wouldn't recommend trying that version unless you are a programmer and want to spend some time trying to figure out how to fix the compile/link errors usually seen with a vanilla 2.5 kernel. -- Peter Osterlund - petero2(a)telia.com http://w1.894.telia.com/~u89404340
