I once sent a patch to -mm:

-#define OK_STAT(stat,good,bad) (((stat)&((good)|(bad)))==(good))
+#define OK_STAT(stat,good,bad) (((stat)&((good)|(bad)))==((stat)&(good)))
#define BAD_R_STAT (BUSY_STAT | ERR_STAT)
#define BAD_W_STAT (BAD_R_STAT | WRERR_STAT)
#define BAD_STAT (BAD_R_STAT | DRQ_STAT)
Assuming hdb is a CDROM/optical drive, then this change makes sense for
that. But I don't think it is a valid (good) change for regular ATA disks.
A more complex patch is required, one which correctly handles each drive
type.
That patch was very ATAPI-specific, and would break other things.
It also would not correctly help anything in Justin's case.
