I recently installed an OCZ 128GB Petrol series SSD into a Dell Vostro 1720 laptop after the stock drive failed.
After two months of light usage (web/email), HDSentinel reports the health of the drive as 75% with 25 bad sectors found. In addition, the system has been unstable (slow boot times, apps taking too long to load, etc).
Is the HDSentinel health accurate, and if so, is it normal? I have another laptop which is 2 years old, with a Samsung SSD, that I use daily. My HDSentinel reports a 96% with no bad sectors and a warning about "#177 Wear Leveling Count".
