This is an actual Tech Support report :
Once I went out to a customer site to investigate what was reported to be a grinding sound coming from the hard drive.
Customer: "Oh! I'm glad you're here, I'm worried that my hard drive's going to crash any minute!"
Technician: "Don't worry. It's not your hard drive. It sounds like it's just the cooling fan."
Customer: "Oh! Really? Thank goodness. Can you fix it? It's really distracting."
Technician: "Sure! No problem."
I lifted the stack of interoffice envelopes that were stacked beside the system and turned them so that the tie strings were no longer hanging into the fan. All my calls should be this easy.
