DASP may refer to any of the following:
1. Short for Drive Active Slave Present, DASP is an ATA signal carried on pin 39 that indicates if a drive is active and indicates to the computer if a slave drive is present. If you're using an older slave drive with a new master drive and cannot get it to detect, see if the drive has a SP jumper, a firmware update, or consider a different channel.
2. Short for Disk Anti-Shock Protection, DASP is a protection system developed by Acer that helps protect a hard drive in a laptop computer from being damaged when it's bumped or dropped.
3. Short for Dynamic Adaptive Speculative Pre-Processor, DASP is a memory prefetch technology developed by Nvidia that helps reduce memory latency.
