next in thread | raw e-mail | index | archive | help
Hi,
my console today shows the following error message from
my disk:
ad2: UDMA ICRC error cmd=3Dread fsbn 74689079 of 74689079-74689206 retrying
ad2: UDMA ICRC error cmd=3Dread fsbn 74689079 of 74689079-74689206 retrying
What exactly does an UDMA ICRC error mean ?
I think this is simply a read error.
AFAIK an IDE disk doesn't have spare sectors or am I wrong ?
How severe is this error ? What do you think ??
Here the output of uname -a and dmesg
