Deactivating wirte cache "Optimize for Quick Removal" for HDDs

[Guest Rudz]

Hello,

 

the option "Optimize for Quick Removal", which kann be activated for

USB-Disks (for disabling write-cache), is greyed out for IDE, SCSI and

FC-LUNs.

 

Does anybody has an idea, how to disable the write-cache (enable "Optimize

for Quick Removal"-option) for disks, where this point is greyed out?

 

Thanks and regards

Rudolf
