What cache are you talking about here? The config option "CONFIG_CDROM_PKTCDVD_BUFFERS" (Free buffers for data gathering) is not used in the 2.4 version of the packet writing patch. -- Peter Osterlund - petero2(a)telia.com http://w1.894.telia.com/~u89404340

New mkudffs
by Ben Fennema 09 Feb '02

09 Feb '02

I've stuck a beta release of my rewritten mkudffs util up on sourceforge. Also included is a moded cdrwtool that works with it. http://prdownloads.sourceforge.net/linux-udf/udftools-1.0.0b1.tar.gz Any problems, suggestions, etc. Let me know.... It should generate much more compliant images than the previous version, as well as supporting generating 2.x images in addition to 1.5. Ben

Hello Norbert. Could you give to me more information how you achieve stable writing to UDF ? What you use ? kernel version: 2.4.17 ? ; kernel patch version: packet-2.4.18-pre4 ? ; pktcdvd options (kernel config menu) - "free buffers for data gathering": 256 ? ; - "writing cache enabled": yes ? ; hardware: IDE 4x8x32 CDRW drive (HP 9100i) ? ; ide-scsi mode for writing (SCSI emulation): yes ? ; udftools version: 1.0.0b ; UDF version for disk formatting: 1.5 ? ; formatting speed: 4x ?; CDRW mount options - noatime: yes - sync: no ? - dev: no You don't get any error like "Ignoring read error on sector:14216" stored in /var/log/messages ? Any file you can read after copying ? I need this information to understand what i'm doing wrong .. Thanks.

Does anyone know how to set this up with SuSE 7.2? I've been using SuSE for 1 year now (just to give some sort of indication of how much experience I have). Thanks, Geraint Jones.
