Re: [gentoo-user] [SOLVED] setting "using_dma" on a BenQ DVD/RW drive

[Joseph <syscon@interbaun.com>]

Problem SOLVED - but another problem pop-up.  Writing to a disk is not
reliable.
I was right, I've missed some setting in the Kernel, 
Device Drivers:
    ATA/ATAPI/MFM/RLL Support
         (x)  Sharing PCI IDE interrupts support
         (x)  Generic PCI IDE Chipset support   
         (x)  VIA82Cxxx Shipset support   #I have this chipset

The first two option must have been the culprit of my problems.
To write two files (44Mb +11Mb =55MB total) to a CDRW it tooks me about
2min.
When I open the drive I can see those two files there 11MB and 44MB
But when I try to copy them back to Hard Drive I get and I/O error

So much if I was relying on these disks for real backup :-/
I would be convinced that the files are there but if I needed them in
emergency I would get an I/O error.
