[Bug 266951] Re: Buffer I/O error on device sr0 Logical Block XXXXXX in Intrepid Ibex Alpha 5

2009-03-07 Thread AL-X
I eventually replaced the DVD device being used for the installation.  I
took the DVD device back to the store, got a store credit, and bought
the most expensive one I could find as a replacement.

[Bug 266951] Re: Buffer I/O error on device sr0 Logical Block XXXXXX in Intrepid Ibex Alpha 5

2009-02-17 Thread AL-X
I suspect this is problem occurs only for WRITE capable devices.  I have
a store-bought CD with Ubuntu install.  In one DVD drive it had the
"error . . . sr0" problem, but in the other DVD drive it did not.  The
difference is that it failed on the burner, but succeeded on the ROM.
(I.e., failed on write capable DVD drive, succeeded on read-only DVD
drive.)

My theory is this: For certain (but not all) write capable (burner) DVD
devices, the OS might be misinformed that it can write to the device.
Upon believing that it has the ability to write, the OS might try to
write.  But of course the **device** capabilities don't matter when the
CD **media** is not in fact write-able; therefore, the attempt to write
fails and an error is reported.

Use a read only device, or try the "all_generic_ide" command line
option, mentioned in Olivier Prieur post of 2009-01-04, above.
