OK, I've used hdparm on a WD 3.5" IDE/PATA - I then formatted it, converted to WBFS using WBFS MAnager, then formatted again to NTFS and then back to WBFS. MY question is: will such a drive in an external enclosure using hdparm keep the spindown information saved somehow, or do I have to use hdparm each time I format to a format Windows can read? The drive is NOT a Passport or equivalent. Just an internal OEM 320GB 3.5" PATA/IDE drive in an external shell. Also could the external case's USB controller cause the spindown?
