It's entirely possible your HDD is failing. These warnings come from the SMART (Self-Monitoring, Analysis and Reporting Technology) system in your BIOS. It monitors read/write, cyclical rate, performs low-impact tests like CRC (Cyclic Redundancy Checks) and sector scans. If it's telling you that you HDD is failing, you really should get it backed up. If it's less than a year old, it's likely under warranty. Get Dell on the phone.

They'll often do an advance RMA and get you a new HDD. You replace the HDD, and you can hook up your old HDD with a SATA-to-USB adapter and boot into a utility like Ultimate Boot CD which has utilities to clone your HDD to the new one, and you'll be back online in no time.

I recently had a solid state hard drive fail on me after only 9 months. Newer tech CAN fail. Never put 100% trust on any hardware.
