We see a lot of portable hard drives that don’t spin up when plugged into a USB port. All brands of hard drive can be effected including Hitachi, Western Digital and Seagate. The problem can be caused by power loss or sometimes due to mis-plugging of the USB lead. This causes the internal read heads to sit on the disc instead of parking on the ramp at the side.
The only way to overcome this problem is by taking the hard drive into our clean room to replace the damaged heads with good ones. This allows us to copy the data from the drive and store it on our server.
The repaired hard drives are not suitable to be reused after this sort of work as they will not work correctly, or fail after a very short time.
