Re: SMART on SATA drives

I have two computers (Dell PowerEdge 400SC, the other homemade) and both
of them have an SATA drives. Previously, the SATA drives were running
in IDE emulation mode in the Bios, and SMART worked prefectly. They are
now both running in native SATA mode, and SMART has stopped working :( The other IDE drive in the systems still reports info correctly with
smartctl.


Any ideas anyone?

smartctl --info /dev/sda

Thanks, Phil




From the smartmon faq: (http://smartmontools.sourceforge.net/#FAQ)

"Smartmontools should work correctly with SATA drives under both Linux 2.4 and 2.6 kernels, /if/ you use the standard IDE drivers in drivers/ide. If you use the new libata drivers, it won't work correctly because libata doesn't yet support the needed ATA-passthrough ioctl() calls. Jeff Garzik, the libata developer, says that this support will be added to libata in the future. When this happens, we'll add support to smartmontools for a new SATA/libata device type '-d sata'. Typically, to force an SATA disk to run using the standard (non-libata) drivers, you must use the BIOS to select "legacy mode" for the controller. If the IDE driver doesn't support your particular SATA controller, or the controller doesn't have a legacy interface, then only libata can be used. Unless the hard disk controller on the system motherboard is Intel, VIA or nVidia, standard IDE drivers may not work."

While you are at the smartmon home page, download the latest version (5.31) and follow the instructions on how to get it installed with fedora core.
