This is usually caused by a single head damage, you can consider use head map editing in RAM or perform hot swap to extract all the possible data, if you need all data, you may need to swap the heads.
If the hard drive is detected, you can use selective head image of DFL-DE or DFL-DDP;
if the hdd is not detected, you can manage to read the tracks and write the tracks to one donor hdd and then do hot swap;
if the tracks couldn’t be read, the last option is to swap the heads. Read more

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.
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.
“One Button ARCO” is a combination of 6B TPI(Density) Correction, 69 Capacity Settings and 46 Optimize. 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.
