silentstorm „Mandrake Linux 9.2 zerstört LG-Laufwerke???????????????????????“
http://www.mandrakelinux.com/en/lgerrata.php3
"The problem was that the kernel would send a FLUSH_CACHE command to the LG CD-ROM drive which would make the drive inoperable by overwriting its firmware. This is because LG CD-ROM drives are not compliant with the ATAPI specification. The specification does not require an implementation of the FLUSH_CACHE command in the driver, and returning an error (or doing nothing) would have been the correct behaviour for the drive. Likewise, reusing a command is against the specification and LG has reused the FLUSH_CACHE command to modify the firmware of the drive, but they are unwilling to disclose exactly what the command does. This FLUSH_CACHE command is supposed to be supported only by CD-RW or DVD-RW devices; the LG-based CD-ROM devices are understanding this command as the UPLOAD_FIRMWARE command.
A new kernel (2.4.22-21mdk) has been released that fixes this problem in the kernel, although the CD-ROM devices are still not up to specification. New CDs and ISOs will be available shortly to correct these problems; they will come with the new kernel.
If an updated firmware for your CD-ROM is available from LG, you are encouraged to apply the firmware update prior to installing Mandrake Linux 9.2. Unfortunately, if the drive becomes inoperable, currently only the manufacturer is able to fix it,."

Kurze Zusammenfassung:
Die Firmware einiger LG-CDRom-Laufwerke interpretiert einen Befehl zum Leeren des
laufwerkseigenen Cache-Speichers (der für RW-Laufwerke gedacht ist), als Befehl
zum Aufspielen einer neuen Firmware.
Dieses Verhalten ist NICHT vereinbar mit den ATAPI-Spezifikationen.
Von seiten Mandrake Linux's wird ein neuer Kernel (2.4.22-21mdk) bereitgestellt,
ebenso werden bald neue CDs und ISOs mit dem modifizeirten Kernel bereitstehen.
Den Nutzern von LG-CDRom-Laufwerken wird nahegelegt, die aktuellste verfügbare
Firmware auf ihr Laufwerk aufzuspielen.
Betroffene Komplettsysteme:
Systems containing LG CD-ROMs that have this problem:
* COMPAQ CRD-8322B(CP1) (same model, but marked as LG; IBM Aptiva 2158-125)
* CRD-8400B (Dell Optiplex gx1)
* CRD-8400B (IBM PC 300 PL)
* CRD-8400B(mi)/CRD-8400C (COMPAQ)
* CRD-8402B/LG CRD-8480C (Dell XPS T650r)
* GCR-8481B (Dell Optiplex gx270; rom 1.06; date: Jun 2003)

* CRD-8482B (Dell Precision 220; rom 1.05)
* GCR-8523B (OEM in custom-built computer)
* GCC 4480B DVD/CD-R/RW/ROM (firmware 1.00; upgrading to 1.01 seems to workaround the problem)
