Jaclaz I need your help in fixing my laptop drive(seagte momentus 7200.4, 320 GB). i thing my drive is affected with the BSY error( drive is spinning but not detected in BIOS). i bought a USB to RS232 cable to communicate with the drive from hyperterminal. Here is what i have done : 1) Removed the PCB and covered the head contacts with a business card and tightened the PCB back. 2) Identified the RX, TX, GND signals from the serial port of the USB TO RS232 adapter. 3) with the tutorials gone through, assumed the terminals just beside the SATA port of the hard drive are RX, TX , GND ( in the same order) & connected the RX TO TX and TX to RX and GND TO GND. 4) opened the hyperterminal and made the settings to 38400/8/N/1/N and entered into the hyperterminal console. 5) Here ctrl+z does not work at all. i tried typing all the characters but the console keeps dumb. ( i could do the loopback test with RX & TX) am i doing anything wrong? how to diagnose the problem with the hyperterminal and hard drive communication. please help me jaclaz, i have read your posts and you gave brilliant solutions. hoping you would help me too!!
