To install a hard disk
This is one of the most typical operations that appear at the time of updating a computer. It does already much of that epoch in which the operating systems were fitting on a diskette; nowadays, a normal installation of Windows 98 or it does not lower ME of "gentle" 150, for not speaking about the immense "suites" crammed with functions that at the time of the truth are ever used.
Nevertheless, it is not precisely one of the tasks easiest of realizing; he is necessary a certain knowledge grade, as well as of true talent of patience and, why not to say it, some luck. If despite this you want to save 5.000 ó 10.000 pesetas that will charge from him for it, or simply feel unhealthy curiosity: there we go!
The instructions are quite exhaustive, therefore, for his serviceability, I recommend to him to print these pages or to keep them on his hard disk. Also, in numerous occasions one alludes to concepts and processes that he should read on the page on the BIOS and in the paragraph on discs IDE of the section of Storage.
Can I do it?
When one considers to install a hard disk, the first thing that must do it is to obtain information about the current configuration of the computer. Before buying nothing, the inexcusable steps are:
1.-Is there space for the hard disk inside the casing of the computer? (The called "bays", already be accessible from the exterior, like the one that occupies the disk drive, or interiors). make sure of it (with the disconnected computer and unburdening itself of static electricity, of the way that is explained in Essentials of the Update).
2.-What format do the bays have? They can be of approximately 15 centimeters for 5,25 inches devices, of 10 centimeters for those 3.5 inches, of sizes not standard, with screws, with rails... the hard disks usually come in 3.5 inches format. In case of ancient computers or mark sometimes adapters will need, because of size or subjection, which can be difficult to find.
3.-Is the hard disk a type IDE (the habitual thing from the epoch of 386)? It might be SCSI (if an expensive computer or a Mac does not have, insurance that not), or slightly even rarer (MFM, ESDI... in general, in "ancient" computers, 286 or previous).
4.-What is the configuration of his current hard disk (or discs, if it possesses more of one)?
5.-What hard disk size is the maximum that admits his computer?
Come to this point, there is imposed a "technological" chat (I waited, still do not flee, it is almost sure that he will support it). On the type of hard disk, at first only we are going to explain in depth the hard disks type IDE, for being the most common; if he wants more information with regard to the identification and other types, especially the SCSI, 1 goes to the Appendix.
To know the current configuration of a hard disk (from now on, of the type IDE exclusively) there are 2 methods:
As soon as there was gathered the information of this point 4, aim at it in a role (or for triplicate, if he wants) and DO NOT LOSE IT, especially if they do not coincide the information of the sticker and that of the BIOS, or if the above mentioned sticker does not exist. On having gone out of the BIOS, do not record the made changes (especially because it should not have changed anything, but sometimes the fingers betray us).
Well, already we have done the first part. If he has answered satisfactorily to the previous questions, and he even knows what hard disk size is the maximum that admits his computer, be congratulated, a coffee and pass be drunk to the section on the installation; if not, it is possible that his problem is in this list:
As the 500 MB hard disks are a recent museum piece, he already will suppose that something was invented to overcome this barrier; this was the method LBA (Logical Block Address). Therefore, to know if it can use a disc of more than 528 MB in his computer (for example, of 2 GB = 2.048 MB), he needs to know if the BIOS (again the BIOS!) he supports the above mentioned way. In the previous pantallazo, the way of the disc was "NORMAL" (logician, because the disc was 420 MB), and in the same column "LBA" would have been selected; for more details, go to the page on BIOS.
Anyway, if there should happen the case of that could not use the way LBA, in the Appendix 3 indicate themselves alternative methods, apart from the simplest: to use the disc as if it did not have any more than 528 MB (true, it is a waste, but it works like last resource).
