I am having this same problem. I have a
DS1621+ (only about 2 months) and I have drive 1 showing 1 reconnect, drive 3 showing 25 reconnects, drive 4 showing 2.. #1 is wd red pro, 3 & 4 wd red plus, all six drives are 4tb. I get the monthly report emailed and has showed the same results for July and now Aug, no change.
I have run extended smart tests, no errors found. No bad sectors, no issues per se, all seems fine as the nas is used daily. But I dont know how to edit or clear these counts to see if the reconnect attempts changes or increases...?
My synology is running DSM6, would the above steps clear this counter for me?
I was able to putty/ssh into the nas, and navigate to the var/log dir and see the file, but than I am unclear, do I remove the disk_overview.xml file or rename it or what? Sorry, very unfamiliar with linux so a detailed step by step would be greatly appreciated and extremely helpful.
Here is the email I have received twice so far:
