In XP, disks can still be optimized for fast removal. In Device Manager, open the property page for the storage device. There should be a Policies tab, which has options for "Optimize for quick removal" vs. "Optimize for performance." On fixed disks, there are also options for controlling write caching.

With XP this control has vanished. When a disk in a device attrached to the PC is shared so that XP can scan the disk as well (via SCSI in this case), there are dangers associated with initiating read and write operations on the hard drive from XP, because XP does not guarantee that the write buffers will be committed to disk instantly. I need therefore to write a .net "Explorer-like" app that reverses this effect, and guarantees that read and write operations are complete, leaving the disk's FAT table up to date, so that disk sharing can continue without any errors being introduced. I would welcome any ideas as to how you think I could achieve this. with kind regards DD.
