With growing magnetic density and precise hard drive mechanics, perfect donor drives are getting harder and harder to track down and head swapsĪfter swapping heads from a matching donor, you may find out that your bad drive is still clicking with the same symptoms.

Is looking for (and with a bit of luck), there is a good chance that all the needed files are already recovered and we don't need to swap heads in the cleanroomĮven if the needed files are not there and the full image is required, acquiring a partial image before taking the drive to the cleanroom can still be very Depending on what kind of data the client The next step is to put the drive on DeepSpar Disk Imager and image all sectors that belong to heads that are good (0 to 6), leaving sectors thatĪs mentioned, it does make sense to analyze the partial image after acquiring data from the good heads. So if we change the head map to 0,1,2,3,4,5,6,6 and instruct the drive to reinitialize, it spins up and starts just fine with the Using a specialized utility, we can modify the hard drive internal RAM memory and “shift” that bad head #7 in the head map Obviously the drive won't ID and won't be (which is very common in the real world), such as head #7, the drive just clicks a few times and spin down. Say we have eight physical heads in the drive, numbered 0 to 7, so the resulting map of used heads looks like 0,1,2,3,4,5,6,7.
Reading data off good heads before ordering the donor for heads replacement is crucial, and sometimes even enough If a hard drive has eight heads, which is a common situation nowadays, it’s possible to get data from seven out of However, with the right tools and technology, a technician can often initialize the hard drive and, at the very least, read data off the good heads withoutĮven opening up the hard drive cover. Of cases, the problem is that one or more of the heads is bad, and the head assembly must be replaced from a matching donor for full recovery. One of the most common symptoms that data recovery companies see in their labs is a hard drive that is clicking and spinning down.
