We purchased a few dozen Dell Optiplex 7040 systems and have found that the internal hard drive on a few of them beeps intermittently. The disk drive is a WD2500LPLX Black.
The beeps are coming from the drive itself (not the internal speaker). After the computer boots into Windows the beeping can take anywhere from 15 minutes to a few hours to start. The beeping continues every 30-60 minutes throughout the day.
I have moved the disk over to other known-working systems and the beeping persists.
WD Utilities, Dell SupportAssist and the BIOS utilities do not detect any disk errors. Nothing in Windows Event Viewer either.
Dell replaced the disk under warranty.
We have had 2 different systems with WD drives that exhibit this behaviour.
I have taken a few videos of the behaviour for reference:
Has anyone else seen this sort of behaviour?
