Good Day Say i want to implement extended set of ATA commands available to userspace for building diagnostic tools. I need 0x40 -- read verify and 0x32 -- write long with error handling, for example. I was trying ide driver through ioctl's, but seems it lack of functionality and full of gotchas. Furthermore it oopses sometimes.
Use the SCSI SG_IO ioctl() with opcode=ATA_16, which gives you access to the ATA Passthrough mechanism. This will work for most ATA commands. I already use it in hdparm and in some other utilities for scanning/repairing drives. A notable exeception are the READ/WRITE LONG opcodes, which require an extra kernel patch from me, awaiting merge into libata some year.
