hi,

this weekend i decided to upgrade from a working installation of fbsd =
4.10
to 5.3
instead of doing a binary or source upgrade, i decided instead to do a
complete reinstall.

after backing up my data and relevant config files, i booted onto the =
5.3
disk1 and began the install.
all went well until it got to actually writing the data to the disk (ie.
extracting base into \ directory)
it gets to between 15% and 18% and then just hangs.=20
looking on the other terminal i see the same error message just =
scrolling up

ad0: WRITE_DMA UDMA ICRC error  ..... blah

this will carry on for a *long* time until it gives up trying.


this never happended with 4.10 so i am quite puzzled.=20

i googled for similar things and found some suggestions that the HDD =
might
be going, so i used a low-level disk checker from hitachi (drive is =
hitachi
80GB) but it came out blank - the disk is fine. (its also quite new - no
more than 6 months)
in the BIOS i tried various combinations of disabling UDMA and 32-bit =
access
and such things but with no luck.

i have an P4 2.6GHz, 1GB RAM on an ASRock PE-Pro HT motherboard with =
onboard
ata IDE controller.

any suggestions would be very gratefully accepted.

also, if you need more info on the machine, please let me know.

much thanks for your help
