So the disc is not (yet) a coaster after all, eh? > What happens if you try to re-run growisofs? Does it fail in the > very same or some other way? OK, I just tried rerunning growisofs again on the same media, twice. It failed in exactly the same way, and dvd+rw-mediainfo gives the same information as the above, nothing changes. > >What could be the problem? Any ideas? > > Try another media brand.

OK, this is wierd, I tried -speed=6 and -speed=4 but growisofs kept saying the "Current Write Speed is 8.2x". # growisofs -speed=6 -dvd-compat -Z /dev/hdc=/tmp/tj1-60.iso Executing 'builtin_dd if=/tmp/tj1-60.iso of=/dev/hdc obs=32k seek=0' /dev/hdc: "Current Write Speed" is 8.2x1385KBps. 0/4679391232 ( 0.0%) @0x, remaining ??:?? 0/4679391232 ( 0.0%) @0x, remaining ??:?? :-[ [EMAIL PROTECTED] failed with SK=3h/ASC=0Ch/ACQ=00h]: Input/output error :-( write failed: Input/output error /dev/hdc: flushing cache /dev/hdc: updating RMA /dev/hdc: closing disc /dev/hdc: reloading tray # growisofs -speed=4 -dvd-compat -Z /dev/hdc=/tmp/tj1-60.iso Executing 'builtin_dd if=/tmp/tj1-60.iso of=/dev/hdc obs=32k seek=0' /dev/hdc: "Current Write Speed" is 8.2x1385KBps. 0/4679391232 ( 0.0%) @0x, remaining ??:?? 0/4679391232 ( 0.0%) @0x, remaining ??:?? :-[ [EMAIL PROTECTED] failed with SK=3h/ASC=0Ch/ACQ=00h]: Input/output error :-( write failed: Input/output error /dev/hdc: flushing cache /dev/hdc: updating RMA /dev/hdc: closing disc /dev/hdc: reloading tray But when I tried -speed=1 then growisofs said "Current Write Speed" is 4.1 and it worked!! ...for a while.

I could mount the disc, and see the list of files, but the files are not readable. The kernel gave these messages when I tried to read the contents of the files: ... attempt to access beyond end of device hdc: rw=0, want=8951444, limit=6863360 Buffer I/O error on device hdc, logical block 2237860 attempt to access beyond end of device hdc: rw=0, want=8951448, limit=6863360 Buffer I/O error on device hdc, logical block 2237861 Argh! This is driving me nuts. I will try different brands and types (DVD+R, DVD+RW, DVD-RW) as soon as I get a chance to buy them, and I will also upgrade the firmware to the latest official version from LG, then I will report back here. One question: why did -speed=N not give Nx, but something different? Thank you so much for replying and for your suggestions, Andy. Ronny
