There are not always precise solutions to what appears to be a straight forward error message in laptop computers. Take the Event ID 51 disk error in Windows for example.
Over the years we have seen common examples where the actual error message points to a rather straightforward piece of hardware, or at least it would appear that way.
One such error which we have seen countless times over the years on XP laptops is the one which can be found in the Computer Management:
"An error was detected on device \Device\Harddisk1\D during a paging operation."
So an error referencing a specific drive will indeed require that the technician know just what drive is being referenced. Keep in mind that there may be multiple drives (particularly in desktop computer towers).
Many of the troubleshooting calls which we have dealt with would be for some issue of the laptop freezing, for BSOD issues or other issues having to do with slow performance. A quick look in the Event Viewer during troubleshooting of the issues often will lead to the above mentioned: "An error was detected on device \Device\Harddisk1\D during a paging operation." Commonly this will more specifically be: Event ID: 51 which would lead one to ultimately think that there is an issue with the hard drive.
While the possible issues that cause this may indeed represent a hard drive which is going bad, in our experience this is not an absolute conclusion. As a matter of fact we have an XP laptop which we have used for years as a test machine that will have multiple instances of this exact error message occur multiple times per day. The XP install has gone for at least a couple of years with the same installation. There have been other times where the OS was reinstalled more frequently. The fact of the matter is that even with XP being installed for over two years, and having this error occurring on a daily basis, the hard drive has never had any issues that would indicate that it is going bad.
The error in reality could be associated to any number of different things such as the swap file (with multiple HDDs), hard drives and power supply issues on desktops. We have seen each of these being the root cause of the slow computer or other complainants like BSOD etc. Ultimately the drive should be further tested if it is suspected to be faulty in refurbished laptops under 200 dollars or brand new ones for that matter. We have seen this as an actual indication of a failing hard disk too, so if you ever do see this obviously the first concern would be making sure that the important data is backed up. Yet it does not necessarily mean that the HDD is actually going bad.
Over the years we have worked warranty contracts where the SLA stipulated that if this error was present that the hard drive was to be replaced immediately. However this was a rare combination.
