Because they're still being made.

At least in the US, most companies, out of fear of getting sued, will only confirm dates of employment. Giving a 2-week notice is a really professional courtesy to your fellow coworkers, to facilitate any transition of work.

You're welcome.

Wait. You have a girlfriend? I thought this is slashdot.

Well, partly at least. It's no secret that disk drives are sensitive to vibration as this video showed an extreme case. Keep in mind, since disk drives are spinning at 7200-15000RPM, they themselves create vibration that can affect adjacent drives. The drive enclosure can help reduce the problem with use of shock absorbers and vibration dampeners. Most drive enclosures nowadays, for cost reasons, are no more than just sheet metal wrapped around power supplies, fans and drives, which contribute to the problem.
