ISO9660 (mount) * mount -t iso9660 works silently on 64-bit system with opensuse 11.1, but the data are unreadable * mount -t iso9660 on 32-bit system was not tested UDF (mount) * mount -t udf works fine on 32-bit system with opensuse 10.3 * mount -t udf on 32-bit + OS 11.1 leads to a complete struggle with the drive while mounting, but later reading is OK. * mount -t udf on 64-bit + OS 11.1 leads to a complete struggle with the drive while mounting, but later reading is OK. So sorry for the previous report, it was misleading.

From those tests it seams that the fault is _not_ with AUTOmounting but with mounting system itself in opensuse 11.1.

I attached external dvd drive -- NEC, and results are surprising -- 64-bit computer, 32-bit opensuse 10.3 and 64-bit opensuse 11.1, mount -t udf and mount -t auto -- silent, immediate operation. So, opensuse didn't like udf disc in HL drive already at times of 10.3, but now things get even worser. Maybe another case of "LG loves Mandrake" (LH = LG + Hitachi). Judging from all the noise OS+LH makes, the rapid movement of the head it is probably advised not to use udf disc in such drives and use external drives, non-LH (if user has such drive). So, there are two issues now: * please make 11.1 perform mount -t udf as 10.3 did -- it is possible for sure * please make opensuse perform mount on LH drives in more gentle way -- it might be not possible, though -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

ISTR there are cases where medium error was caused when the burning was done with incorrect parameters (it was padding related, I don't remember exactly). In those cases, the IO errors were localized to the last few sectors. Can't tell whether this is your case tho. I can tell you that brasero doesn't make such mistakes when burning regular iso images but I don't have much experience with udf. At any rate, this doesn't seem to be a driver related problem. For whatever reason, the drive can't read certain sectors off the media so the struggle and errors. As it's more likely to be a hardware / media problem, I'm afraid the only way to debug the problem is to eliminate causes one by one. ie. Try different recorder (this would be my first bet), try different readers, try different media and so on. I'm resolving as INVALID for now. Please feel free to reopen if there's anything indicating software problem.

Hello, Jan. Has udf behavior changed during mount between SL103 and SL111? It seems that during mount SL111 is trying to access sectors near the end of the media while SL103 didn't. I'm not sure where the access is coming from but if mount -t udf is showing different behaviors, it's likely to be something inside the udf code, right?

Essentially it plays role of superblock. The problem with this block is that it can be on several places in the media and it depends on the creator of the media which position he chooses. Furthermore some of these positions are relative to the end of the media (recorded area) and some drives misreport size of this area. OpenSuse 11.1 is different from OpenSUSE10.3 in the fact that it checks some more placements of anchor block (previously we were missing some places required by the standard) and we check even some more to compensate for drives reporting recorded area wrongly. I guess some of these places are what makes problem to your media. I'll attach here a debug patch that will report which blocks we are trying (and what recorded size the drive reports). Please try a kernel with this patch applied and send me the resulting kernel messages. I'll have a look whether we can somehow reasonably workaround problems your drive has. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It contains all the info I need. What happens is that your drive reports that the last recorded block on the media is 2295103 (in 2048 bytes sized blocks) but apparently it's not able to read anywhere nearby before it. Finally we find the anchor block in block 256 (either the media is open or it is not standard compliant) but we check all the blocks near the end of the media earlier and that's causing troubles to your drive. I've checked the UDF standard and it seems we are allowed to try block 256 first and use it if it's OK but it needs larger code modification because currently we first check which of the all allowed blocks look reasonable and only after that fully verify which blocks are completely fine. So even if I put block 256 in front of the sequence we'd try reading blocks near the end of the media anyway. So stay tuned. Tejun, I'm taking the bug since this really seems like UDF which is making difference.
