MacBook Pro eSATA Support for S.M.A.R.T. Status

Last updated May 18, 2010 - Send Feedback

S.M.A.R.T status is important for detecting imminent drive failures and other issues that could cause data loss (eg excessive bad blocks).

The OWC Slim and Sonnet Tempo SATA Pro both report SMART status, but the Sonnet Edge does not.

OWC Slim

The OWC has the correct disk description, correct connection type and verifies SMART status.

Sonnet Tempo SATA Pro

The Sonnet Tempo SATA Pro is reported as an internal drive, which is a bit odd. But it does verify SMART status.

Sonnet SATA Edge

The Sonnet Edge not only mis-spells the drive name, but does not support SMART status. Oddly, it is reported as a SCSSI device also.
