There should not be problems using ide storage, but I don't think xfs has 
been exercised as completely (e.g., the really exceptional cases) on 
low-end hardware, so we don't really know if the people who say it works 
for them were just lucky.  I've had to use xfs_repair a few times on SGI 
machines after a kernel oops or similar rare event, but only once on a PC. 
In the latter case the system didn't have enough memory for xfs_repair to 
run, so I really don't know if it would have worked given more than the 
256M that was considered generous when the PIII was young.
