Hello David, Wednesday, June 12, 2002, 11:19:16 PM, you textually orated:
DT> -----BEGIN PGP SIGNED MESSAGE----- DT> Hash: SHA1 DT> What was Mr. Lord (author of hdparm) smoking? DT> - From the man page: DT> - -S Set the standby (spindown) timeout for the drive. This value DT> is used by the drive to determine how long to wait (with no DT> disk activity) before turning off the spindle motor to save DT> power. Under such circumstances, the drive may take as long DT> as 30 seconds to respond to a subsequent disk access, though DT> most drives are much quicker. The encoding of the timeout DT> value is somewhat peculiar. A value of zero means "off". DT> Values from 1 to 240 specify multiples of 5 seconds, for DT> timeouts from 5 seconds to 20 minutes. Values from 241 to DT> 251 specify from 1 to 11 units of 30 minutes, for timeouts DT> from 30 minutes to 5.5 hours. A value of 252 signifies a DT> timeout of 21 minutes, 253 sets a vendor-defined timeout, and DT> 255 is interpreted as 21 minutes plus 15 seconds. DT> ..."somewhat peculiar"? DT> *boggle* -d I would bet that this is not his doing, but the doing of those that wrote the ATA specification. They likely didn't want to make something too complicated since most BIOSes work under a limited amount of memory so they tried to come up with something that would work in a single byte. The other tip-off would be that 253 sets a vendor defined time-out. I doubt hdparm has the vendor defined timeouts for every drive out there.
