We’ve came up with a freeware tool that handles LBA48 mode setting as well as HPA and DCO features. ![]() If steps 1-3 did not help, then we have a very cool tool that analyzes your hard drive’s LBA48, HPA and DCO status and recovers factory settings (see below). QDI SUPERB 4E MOTHERBOARD MANUAL FREERun Windows Disk Management console and see if there is any free space that is not used by any partition.Ĥ. Check your OS, does it have all updates installed?ģ. Consult with manufacturer’s instructions and set jumpers to the proper position.Ģ. In this case there is nothing you can do about that. Sometimes a very broken hard drive may report wrong capacity. In this case you would need to use a zero-fill tool. These include things like HDD firmware bugs (believe me, there are plenty of them).Īlso, sometimes a damaged Master Boot Record may cause the BIOS and/or the Operating System to misdetect the true hard drive capacity. Most hard drives have a special jumper setting that allows you to limit their capacity to either 32 or 128 (137) gigabytes. Jumper settings that limit hard drive capacity They will use their own DCO tools to lock capacity to 40GB. Example: they need to ship 1000000 computers with 40GB hard drives, but they only have 80GB drives in stock. Some manufacturers (for example, Dell and HP) use DCO to reduce capacity for marketing needs. MHDD can also access DCO (Device Configuration Overlay), and that allows you to not only change hard drive’s capacity, but also switch some hard drive functions, such as LBA48 support, Security commands support and others. QDI SUPERB 4E MOTHERBOARD MANUAL SOFTWAREThis software allows you to set a Host protected area on your hard drive, so the hard drive will report less capacity to both BIOS and Operating System. Software that has the ability to control HPA and DCOįor example, MHDD. This is needed because most BIOSes will disable HPA/DCO operations to ensure that nothing can reset or damage that hidden area. In this case, to restore the original capacity of the hard drive with the HDD Capacity Restore tool that we include in this article, you may need to remove the hard drive out of its original PC/laptop and temporary attach it to another PC. Usually this area is quite large (8-20 GB). QDI SUPERB 4E MOTHERBOARD MANUAL PCThis area is used when you want to restore the original state of your desktop PC or laptop without using CD/DVD disks. Manufacturer of your PC can create a “Host protected area” on your hard drive to store an image of the original operating system and programs. ![]() Usually this area is not bigger than 10 megabytes, so there is nothing to worry about. Motherboard can create a so-called “Host protected area” on your hard drive to store its data. One decimal gigabyte contains 1 000 000 000 bytes (1000 x 1000 x 1000), whereas one binary gigabyte contains 1 073 741 824 bytes (1024 x 1024 x 1024) - that’s more than a 7% difference! So, your 300 GB hard drive will show up in Windows as a 279 GB hard drive. Hard drive manufacturers use decimal gigabytes while operating systems use binary gigabytes. Windows Vista does not have any issue with big drives. QDI SUPERB 4E MOTHERBOARD MANUAL INSTALLWindows 2000, 2003 and XP do not support big drives by default you will have to install the latest service pack in order to get big drives working properly on these OS. There are ways to get around this problem, but since these Operating Systems are rather rare nowadays, I do not see the point of writing about them. Windows 95, Windows 98 and Windows ME will not support big drives (>137GB) even if you install all hotfixes. Operating System does not support LBA-48 addressing mode Now I will go through these things one-by-one and provide some more details.
