It should, but so far I know it cannot do every thing with
dma.
My writer use:
pingi2:~ # hdparm -v /dev/hdc
/dev/hdc:
HDIO_GET_MULTCOUNT failed: Input/output error
IO_support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 0 (off)
keepsettings = 0 (off)
readonly = 0 (off)
BLKRAGET failed: Input/output error
HDIO_GETGEO failed: Invalid argument
And I see no problems.
At least you can try hdparm -u1 (use a RW media).
