Solutions for Seagate Barracuda 7200.11 HDD Common Errors(Part I)

December 14th, 2010

There are two common errors on Seagate Barracuda 7200.11 HDDs (caused by bugs on firmware):

  • 0 LBA error: it happens when your BIOS can recognize your HDD at POST moment, but as an 0MB drive.
  • BSY error: it happens when your HDD enter on a halt state, or Busy state. In this condition, your HDD will not be recognized by BIOS at POST moment.

Solutions: You’ll need: TTL adapter

Attention: This guide might not be to every case. No responsible for any damage or data loss it can happen.

Connect TX and RX ports with RS232 to TLL adapter, you’ll need something like jumpers in order to do that, or soldering directly to the PCB board. Connect GND and +5V to PC power supply, or similar. Keep in mind those are direct from Seagate sides, so you’ll need to connect in this way:

– From PC (TX) to >>> RX (on Seagate)
– From PC (RX) to >>> TX (on Seagate)

You can use RED wire (+5V) from PC power supply. Blacks are GNDs (yellow is +12V so don’t use it).

If you don’t want to mess with power supply, just use a CR2032 (3V) battery:
