hda - errors at startup

[René L. Reingard]

Hi,
since three days when starting the machine Ubuntu hangs either at

* Setting up LVM Volume Group

or

* Loading modules ....
hda: timeout waiting for DMA
hda: no DRQ after issuing MULTWRITE

what i did the last two weeks regarding Harddrive is that i set it from  
ext3 filesystem to ext2, because I started tu use the program Wipe.

do I have to consider buying a new harddrive soon, haha.

thanks for help.
René
