Hitachi HTS725050A9A362 500GB Hard Drive With A Bad Head

A computer shop in Salina referred this drive to us. It was spinning up but not accessible with their recovery equipment. After a quick diagnosis, I found that 1 of the 4 heads inside the drive was not working properly. In this case it was head 2 that was not functioning, leaving the drive unrecoverable by software-based methods.

The bad head was not damaging the platter, so I continued with getting the data back from the other 3 good heads. When this imaging process was done I had gotten back 75% of the sectors on the drive (3/4 heads worth). I contacted the customer asking if they wanted to stop with 75% of the data for our base fee, or if they wanted to continue with a head swap to get as much data as possible from the rest of the drive.

In this case the customer decided to go with a head swap recovery so I ordered the donor parts needed and waited for their arrival. Once the recovery parts arrived I continued with the head swap, which went really well. I had already imaged 75% of the drive, so I was able to just focus on imaging the final 25%.

This head swap recovery was a success with 94% of all sectors being successfully imaged. The customer was pleased to have their important data back, safe and sound.
