IBM Deskstar Hard Drive
I have an IBM Deskstar hard drive with 100GB of storage space. I went out on a trip over the weekend and I left my computer open for the entire time since I was copying some stuff from my camcorder that takes a lot of time to finish. I normally do this when I go on short trips and it has never been an issue. When I got back from the trip this morning, I found that all the files did not upload successfully so I decided to turn off the computer and let it rest. In the afternoon, I thought that the computer had already enough rest, which is almost always how long I let it rest before. When I turned it on it would not boot up past the bios screen. I received ‘no boot disk detected error’.
IBM DHAA-2540 HDD
I have a super old IBM DHAA-2540 HDD that will not power on even what I try to do. It came from an old computer at home and I believe it contains most of the codes I created when I was younger. I wanted to gain access on those codes, which is why I am trying to breathe new life to that HDD. Unfortunately, it seems that it is completely dead. The LED light on the hard drive doesn’t even power on. I have tried other hard drives with even bigger power drain using the same connection and they turn on fine so I am sure that the adapter is working. I can hear the other drives spin, which is proof that they turned on when connected. I am thinking that the IBM DHAA-2540 HDD might be dead because of its PCB.
IBM Disk Repair
A world leader in the production of personal computers IBM have been manufacturing computers for many years now but even with their expertise in the field problems can still arise with the hard drives in their machines.
Hard drives across all makes and models of computer are common and sadly cannot be avoided so it is important to have an understanding of when you should call for professional help.
One of the most common factors when it comes to hard disk problems is human intervention, or perhaps lack of. A great many users will run diagnostic checks and continue to use the computer in the hope that the problem will rectify itself or indeed cease to be. Unfortunately as we have all found out to our cost at one point in time is that this is sadly not the case and the longer it takes to deal with a hard disk issue, the harder it is to reclaim your data should that disk fail, especially without the aid of a professional such as the experts at www.brighton-datarecovery.co.uk
When it comes to hard drive problems you will find that the drive – in conjunction with the operating system – will attempt to save data as a series of mathematical equations which can then be reinterpreted as the data later on. This is carried out using a series of error correction codes (ECCs) most commonly the Reed Solomon Error Correction system.
In more recent years however this system – although still in operation – has been superseded by low-density parity check codes.
Using this method a hard drive will attempt to redistribute – or remap – the physical information across the drive thus avoiding those bad sectors on the disk. However when this occurs the spreading out of the data means that it is no longer kept neatly in one area of the disk and in practice is similar to keeping information in a series of filing cabinets instead of just one.
Of course in recent times IBM have been providing hard drives for a variety of other manufacturers and their machines and problems arise with these drives too.
Mostly commonly are problems arising from not being able to boot from the hard drive. The disk appears to be spinning up but is not booting or allowing access to the relevant boot sectors upon which the disk operating system is held. It is worth noting that using a system’s internal recovery system may resolve the problem but the information held on the drive will be lost.
Persistent or intermittent beeping or a sound that is referred to as ‘the click of death’ often indicates these problems. If this noise is something that you are hearing on a regular basis or indeed at start-up you should consider having the disk replaced and having its information recovered before you reach the point of no return and find that the data is lost.
