I'm trying to do packet writing with my new DVD writer.
# cat /proc/ide/hdc/model PIONEER DVD-RW DVR-107D
dma enabled. After some tests with 2.4 I decided to switch to 2.6. I used Fedora Core 2 with a vanilla kernel 2.6.8.1 + patch from http://w1.894.telia.com/~u89404340/patches/packet/2.6/, udftools with Petero patch (http://w1.894.telia.com/~u89404340/patches/packet/, same site and author).
However I get a lot of problems mount/unmounting devices...
DVD+RW mkudffs /dev/hdc does not works... doing a strace opening /dev/hdc for read/write open returns EROFS (or similar). I tried with blockdev --setrw but still same errors... Than I used pktsetup. mkudffs with packet device (/dev/pktcdvd/test) worked so I mounted it (still /dev/hdc report readonly so I used /dev/pktcdvd/test). I copied a directory (4 MB) an deleted it. Then I unmounted device and then waited... after a while DVD led turned off and DVD spin down... umount command still not exited... I waited 20 minutes but still hangs so I restarted my PC.
DVD-RW After a lot of tests I realized that I have to use dvd+rw-format with -force=full cause DVD was not empty. Then I used pktsetup and mkudffs (with no problem). I tried to mount my DVD but mount (not umount) hangs. Using ps it seems than mount call wait_to_buffer. After 10/15 minutes I restarted my PC...
I have also a SCSI CD recorder (Waitec WT4260) and a CDRW formatted with UDF (using 2.4.23 and an old patch from Petero site) and it works without problems... Is the problem related to IDE or to DVD ??
I'm not (still :) ? ) a linux guru and I don't know how to debug or what check should I execute... Should I send my .config ? Stop some daemons ? Work without X ?
