Enclosure-Related Problems
An LED is blinking red on an enclosure.
A blinking red LED on an enclosure may indicate that there is a “predicted
fault” on the drive in that slot. Actual LED behavior will depend on the
enclosure manufacturer. Refer to the user guide for your enclosure.
Such an error can result from a number of different factors, including a
SMART error, read error, or cable error. The drive has not failed yet, but may
fail soon.
