Here is the story.
I have bought a lite-on 812s and experimented a lot of difficulties to use it successfully under Linux. It seems that buffer underruns occur excessively. After trying various OS and softwares tweaks without result, I decided to give a try with a newer firmware than the one provided with the drive (US05).
Because I don’t have any windows partitions on my system, I did the following steps:
-boot on a emulated winxp (vmware linux) to extract US0N.BIN from US0N.EXE with xflashx-2.2.1
-copy mtkflash.exe (1.80.1) and US0N.BIN on a floppy
-boot the real computer from a win98se boot floppy without cdrom support
-remove the win98 boot floppy and put the floppy with mtkflash and US0N.BIN
-MTKFLASH.EXE 4 W US0N.BIN (slave on secondary ide)
I have waited until the erasing/flashing procedure was over and the message “please reboot computer” was displayed.
Since, the drive seems to be dead: no led activity when power on, eject button doesn’t work anymore, Bios doesn’t detect it anymore…
I know I should backup the original firmware first, but I didn’t
I have try various 812S firmwares in binary format found on http://dhc014.rpc1.org. The erasing/flashing procedure did its job, but no results.
What can I do ?
