A computer with two IDE drives on one cable may stop responding (hang) when the computer resumes from standby.
The IDE disk driver does not check the busy bit in the drive status before resetting the drive. This creates a problem with computers that use the S3 sleep state for standby. This state cuts power to the drive instead of issuing a sleep command to the drive as in the S2 standby state. This causes the drives to be reset before the drive negotiation is finished when the drives restart. The specification for ATAPI drives calls for checking the busy bit before resetting the drive. The specification also states that the drive ignore resets until the drives are synchronized and ready to operate after negotiation. Some drives that are currently being sold do not do this. This can cause computers with two drives to start with both drives programmed to be the master on the same cable, causing the computer to hang.
