Comment 73 for bug 267913

Notable correction: I should have written 3Gbit/s SATA, not 3GB/s. This amounts to a maximum transfer rate of around 45MB/s.

Correction to the information request above: please run badblocks BEFORE any of the other steps, including looking in Disk Utility or running smarctl. (You may have to install smartmontools [spelling?] to have that command available when the time comes.) If you run badblocks first, it will ensure that all sector replacements made from reserved blocks to compensate for read errors during the badblocks test (which reads every block on the drive) will get logged, and thereby provide a more accurate picture of whether bad sectors exist, but have been replaced and hidden/disabled by SMART. This is especially relevant if SMART wasn't already enabled in BIOS, as it will need an opportunity to start gathering data for the log that you will be checking later via Disk Utility and smartctl.
