I have read this thread with great interest. I have a Synology NAS unit with five WD Red disks. I have the serial numbers and capacities, which are three 3 TB and two 4 TB. I also have two WD red disks of 1TB each coming tomorrow for a second NAS unit that is built by me from very ancient PC remains, running now with one Toshiba disk that will be alone and not in the WD raid that I plan to set up there, that will be using Nas4Free software.
My questions are, and I apologize for my lack of knowledge of how to determine these items:
How are you all determining the idle3 setting and where would I see this? Synology software is very comprehensive and I will examine the disk options to see if these are listed.
Where are you all seeing your present Load cycles?
Does this load cycle indicate the number of times that the disk is accessed by the sytem, in 24 hours?
I realize that these disks are Smart enabled and have what are supposed to be excellent NAS characteristics, but I am now concerned about this thread and the action of these disks.
Any knowledget that you can send my way is appreciated,
EDIT: I did find the information on SMART information for the WD Red disks in the Synology unit, under Menu, Storage, Disks, Smart, Information. I do not see the Idle setting however, but I see many of the items shown in the screenshot in this thread. If someone could help me to understand these items, I would be grateful. I do see the smart information also for the Toshiba HDD in the Nas4free unit, but again, no idle time. I do need help understanding all these items in the list.
EDIT 2: I did figure out what I need. I studied these posts for over two hours last night and today. I got the report from my Synology under Storage Management-HDD Management-SMART Info, and saw the attributes and values. One of the posts here said to check the values of “Load_Cycle_Count” and “Power-Off_Retract_Count” and “Start_Stop_Count” which should all be close or equal. Three of my disks(the 3 TB) were fine in this regard. The other two, the 4 TB, were not. Disk 4 and 5 had a LCC of 10865, whilst SSC was 503. not good. So I knew that the idle timer was set bad probably to 8 sec. So I had to create a bootable floppy(It has been about 20 yrs since I dealt with dos and this took about an hour fo rme to get this done, I’m afraid to say). Then I was able to shut down the Synology and remove one disk at a time, and insert it into my pc and remove connections to my real HDDs there, and start to dos, and then run this WDIDLE3 tool. It is also documented on the Synology website at: http://www.synology.com/en-us/support/faq/407
So I have applied correctly and successfully this tool and will be checking my values in smart info. for LLC to see how they are coming along. I am hoping that the two WD Reds that I am expecting tomorrow (1 TB) will not have this issue, and I do not know how to determine it, only that I guess I’ll have to use this tool to apply the timer before I insert them into my new Nas4Free unit that I built from old pc parts.
