Thank you Panagiotis for your examples of how your drives are behaving with If I set the app to start as resident, I will let you know if the settings stay, I am sure they will. On my Blue Scorpio, but this CrystalDiskInfo does work for my needs. On this WD I am using in the desktop, I had tried the WD tool that you couldīoot from and adjust the APM settings, but it only worked on a few models, and it did not work correctly I think there are other options out there for apps that handle APM settings, such as 'HDParm', Not an issue for me, but I will likelyĬhange the app to start with windows if that keeps the setting so i will not have to reset each time although it only takes Per session if one does not keep the app to start with windows. I just booted the desktop, and you are correct, I had to reset the APM, so it does appear it is Upon the app running resident, although one can do this if desired for disk monitoring i think.

As far as I can tell, the changes was made, and is not dependent I have notīooted the tower up this morning yet, but as of last night, the setting did not change after Seemed to be fine and the drive did not do any more parking. Not sure about having to have it resident, I simply did the setting, enabled it, then closed Hope this helps, it has worked great for me, at least it did what it said it could I downloaded just the portable version, (Standard addition), but there are several available here: (all free) I noticedīetter performance immediately with my drive, no more delays while waiting for drive to respond from Since I set the APM to 'max performance', adjusting slide control to 'FEh', then click 'Enable', the drive now performsĪs I desire it to, without constantly parking heads and causing delays of program launch, etc. The APM control is very flexible,Ī lot of settings in which you can read about here:Īdditional instructions can be found here: Head parking, etc., but of course you could always disable if desired. In my case, I did not disable the APMįeatures of the drive, a laptop/mobile WD500GB Blue Scorpio that I am using in a tower setup, but I didĪdjust the APM to 'Maximum performance' by setting the control slider to the proper code. You can open a control that handles both AAM/APM settings. Personally, I have found CrystalDiskInfo to do a great job at handling APM issues.
