IIRC, you need a reasonably modern 2.6 kernel (early 2005)
if you want fsync() to flush the write caches on hard
disks (IDE and SATA and SCSI included). The Linux SATA
driver author explains here:

Anyone know if those write barrier patches were ever
backported into the 2.4 kernels?
If not, I think you need to either use 2.6 or disable
the disk's write caches and suffer the performance hits.
