SUSE对SATA硬盘支持好吗？

本人用两个200G的SATA做了一个RAID1 使用REISERFS后来又删了改用JFS。。。接着就出问题了，，不能格式化也不能删分区。。。唉。。。痛苦。。。
suse-p3x4:/mnt # time mkfs.reiserfs /dev/hda1 -f
mkfs.reiserfs 3.6.13 (2003 http://www.namesys.com)

A pair of credits:
BigStorage (http://www.bigstorage.com) contributes to our general fund every month,
and has done so for quite a long time.

SuSE (http://www.suse.com) pays for continuing work on journaling for version 3, paid
for much of the previous version 3 work, and is paying for Chris and Jeff to do
V3 maintenance. Reiserfs integration in their distro is consistently solid, and
they were key to our becoming widely used.


Guessing about desired format.. Kernel 2.6.5-7.97-smp is running.
Format 3.6 with standard journal
Count of blocks on the device: 49785424
Number of blocks consumed by mkreiserfs formatting process: 9731
Blocksize: 4096
Hash function used to sort names: "r5"
Journal Size 8193 blocks (first block 18)
Journal Max transaction length 1024
inode generation number: 0
UUID: bb72dafa-561a-4e78-a73b-567af8e81b42
Initializing journal - 0%....20%....40%....60%....80%....100%
Syncing..ok
ReiserFS is successfully created on /dev/hda1.

suse-p3x4:/mnt/hdc1 # cat testfs.sh
for i in 1 2 3 4 5 6 7 8 9 10;
do
time dd if=/dev/zero of=test.$i bs=1GB count=1 >/root/testfs_log_reiser;
done

直接用parted不能删除分区吗？
