You may need to turn off disk write-back caching on your PC. Database systems require tight control of hard disks to avoid disk corruption. Write back caches will pretend to write data to the disk before actually doing so. This means that if the PC is turned off (or explodes or the power fails) between the cache pretending to have written the data and it actually being written, the data will be lost, and this can cause the database to be corrupted.
To disable write caching:
Note that if you disable write-back caching then you will slow down the disk access on the PC, so the choice is really yours whether you prefer the speed of having it enabled or the safety of disabling it. Using server PC hardware with battery backed cache is the best option if you need both the speed and the safety.
