Question

You have a hard drive that periodically mounts and unmounts itself. It is obviously a failing hard drive, but, you have data on the drive that you need to preserve. The drive is not part of a RAID array and is the only source of the data. How would you go about saving the data?✱

Answer 1

• The communication of hardware is controlled by the drive controller board.
• By using a RAID array, the data is stored simultaneously in many harddisks.
• So even though if anyone fails, data recovery is possible.
• But here the drive is not a part of a RAID array.
• As the communication of hardware is controlled by the drive controlled board, its malfunction may result in such mounts and unmounts.
• So it is better to replace the drive controller board inside the harddisk.
• Therefore in order to save the data, we can do the replacement of the drive controller board inside the harddisk.
