THE DEFECT HISTORY, IN ORDERWhen we received it: 0 grown defects, 13721 hours.After our first full zero overwrite of all 4 TB: 21 grown defects.After a second full pass over all 4 TB: still 21 grown defects, 13744hours. Uncorrected errors were 0 at every reading.
A remapped sector is not lost data - the drive moved that location to aspare and carries on. What matters is whether the count keeps climbing.On this drive it stopped.
HONEST ASSESSMENTA used enterprise drive with a moderate, stable defect count. Reasonablefor a lab, scratch space, or a redundant array where you monitor SMART.Not for the only copy of anything important. Check the grown defect countyourself on arrival - it should read 21.
INTERFACE NOTEThis is a SAS drive. It will NOT work in a SATA port. You need a SAScontroller or backplane.
DATA SANITIZATIONEvery logical block was overwritten with zeros, running until the driveitself reported end-of-media. We then read back the start, middle and endand confirmed all three contained zero non-zero bytes. The per-drive logrecords RESULT: WIPE VERIFIED OK. It arrives fully zeroed with no partitiontable.
