[protect password=”greendolphin”]

ARCO-Advanced Read Communication Optimization. ARCO is usually used when the FW modules have a total replacement, otherwise, you don’t need to run ARCO at all or you may run the ’46 Optimize’only.

Steps to Run ARCO

Run ‘Initialization’ under ‘Online ARCO’ so that all the adaptive parameters, zone parameters, etc can be set to default and all logs will be cleared automatically;

Generation orders to run ARCO is to run ‘6f Optimize’,’6a Optimize’, ‘6b Optimize’,’69 Optimize’,’46 Optimize’. For some drives, you may run ‘6a Optimize’before ‘6f Optimize’if you fail to run ‘6f Optimize’in the beginning.

Below ‘One Button ARCO’ in the DFL-WDII hdd repair program, you can find five separated Selftest processes and they are ‘6F Optimize’-TouchDn Correction, ‘6A Optimize’-GAP R/W Correction, ’46 Optimize’-Complete Channel Optimization, ’69 Optimize’-Capacity Settings, ‘6B Optimize’-TPI Correction.
