Samsung. How to solve LED 1A04 error and get fast data access if heads are weak.

    Model : SAMSUNG HM100UX
  Serial : C5091E861A5DDY
Firmware : 2AM10001
Capacity : 1 000 GB (1 953 525 168)

Hello Friends!

Today we would like to briefly review how to solve the LED 1A04 error that comes up frequently during the data recovery process from Samsung drives. In the beginning, it looks like that the FW is readable, but then something prevents the drive initialization and it just hangs. So, you can’t read the data as well as Service or User Areas.

Let’s consider this issue on the example of Samsung HM321HI 2.5″ drive.

First of all, you should start the correct utility. Select the 2.5″ M7E drive family. Please note, that the terminal must be connected.

The drive is in the Busy state, the utility initialization was terminated:
