Frequent "Waiting for buffers to recover" warnings

[mathesar]

Whenever I burn discs I almost always see this warning during the burn:

 

I 16:03:09 Writing Layer 1... (LBA: 1913760 - 3827487)

W 16:03:21 Waiting for buffers to recover... (LBA: 1915200)

W 16:03:22 Waiting for hard disk activity to reach threshold level...

 

Also during a burn I see the "Device Buffer" bar always going up and down rapidly, I haven't had any burns fail due to this but I'm just curious why its happening so often, even if I'm just browsing the web during the burn.

 

Can this problem be associated with the burner itself? My PC has 6GB ram doubt its running out of memory.. Any ideas appreciated

 

The burner is a Sony Optiarc AD-7240S-0B (SATA)

 

Rest of PC spec:

 

i7 920 @ 3.2ghz / Gigabyte EX58-UD3R

6GB Corsair DDR3 1600 / Triple channel

EVGA GTX 260 / 216 Core Superclocked edition

DMA issues (read the FAQ), drive fragmentation (defrag your drive), something else using the same physical hdd at the same time (stop them).

 

Once you've exhausted those, try the 'Always use buffered I/O' option in the settings on the 'I/O' tab.

 

Some PC's really don't work well with that being off - for everyone else it's normally better.

All my NEC based Optiarcs have that behaviour and it's normal.
