Hello
Can anybody help ?
I can't successfully write to CDRW disc a large file (> 50 MB) - too many i/o errors.
How i can decrease writing speed of pktcdvd layer ?
You have to edit the source code. In the pkt_open_write function, there is a call to pkt_adjust_speed. Change the "16" to the speed you want to use.
I have CDRW drive with 4X write speed and when i start to copy big file (500 Mbytes) to /mnt/cdrw using mc system shows writing speed about 9 MB/s (should be no more then 600 KB/s).
Maybe if the writes start to fail, they can fail with a speed faster than 600Kb/s.
No, the truth is that the data is "copied" to buffer cache and that does the writing in the background.
Yes I know that, but I thought the phrase "system shows writing speed ..." was referring to information from "vmstat" or equivalent, which shows how much data goes to the device. If the 9Mb/s value came from mc, I agree the information is not very useful because of the caching. -- Peter Osterlund - petero2@telia.com http://w1.894.telia.com/~u89404340
