However, this option does not exist within Dell’s BIOS Setup. With other machines, the problem can be resolved by switching ON “Hot plug support” (or similar) in the BIOS Setup. This indicates that the problem has to do with the machine not detecting the drive quickly enough during POST to continue with the boot process. Interestingly, if the user presses F1 to retry, the machine then boots normally. The message you will see on a Dell Latitude if this happens to you is: Specifically, some of the newer Dell Latitude laptops (of which I purchase and service quite a large number) seem to struggle with Crucial SSDs. Reliability hasn’t been a concern with regard to the drives I’ve purchased for my clients, but on occasion, drive detection is a problem.

This applies most notably to sleep/resume and cold boot detection of these devices, which sometimes are not detected at all on specific systems. A relatively new form of problem which has been introduced by the wider adoption of solid-state drives (and other drives with more particular power requirements than standard mechanical hard drives) is that of drive detection and compatibility.
