Jonathan Crone comments about the blinking LED on his Seagate ...

7 blinks means the drive is unable to find and read an ID mark for any sector.

For the ST125N/138N/157N, here are the power up error codes:

- Microprocessor/Internal memory test.  Failure is indicated by 1 flash

- Microprocessor ROM checksum test.  Failure is indicated by 2 flashes.

- Controller chip test.  Failure is indicated by 3 flashes.

- Controller program RAM test.  Failure is 4 flashes.

- Data buffer RAM test.  Failure = 5 flashes.

- Spindle speed test.  If the drive is unable to reach and maintain correct
  spindle speed, 6 flashes will be returned.

- READ SECTOR ID MARK.  If the controller is unable to find and read an ID mark
  for any sector, seven flashes are returned.

- Read Operating System Microcode from Drive.  If the controller is unable to
  read the operating system from the drive, eight flashes are returned.  If the
  controller reads the operating system records, but determines they are
  invalid, nine flashes are returned.  NOTE: this is the Seagate OS and not the
  AmigaDOS we're talking about there!   :-)
