/dev/md0 would be the first raid array.  You have an external drive as
 part of a raid array?  I'm not saying that its not useful, I'm just


 Without running fdisk to create a partition, you've attempted to write a
 filesystem on the whole device.  There shouldn't be a problem with this
 so I don't know what the problem is.

The process was freezed at "Writing inode tables: ...", I was afaid to
cause an encosure and external HDD damange if I kill the process. I
waited for 5 hours, the format process was still stuck at the last
line, I have no choice but kill the process before going to sleep. I
could not event kill the process, and could not event turn my PC off,
the whole system was stuck. I had to physically switched the PC power
off. It was a mess.

Anyway, now I am restarting the fdisk and mkfs.ext3. I made only one
partition for the whole 250 G, that the command "mkfs.ext3 /dev/md0"
once again stuck at last line of "Writing inode tables: ...". I can
only thought of following problems:

(a) The partition of 250 G is too big, the debian system or encolusre
or HDD is not eable to do a format on 250 G. Is it correct? If so,
what is the largest the parttion I can make in Debian 4.0 system?

(b) The enclusure or HDD is not functional properly?

(c) My command to partition and format is not correct?

Thanks Doug.

250G partition should not be a problem at all with ext3, depending on architecture, ext3 can go as high as 32T. It seems as though you might have some hardware issues though. Have you tested each disk in your raid separately?
