Most of your desktop computers will probably be equipped with ATA drives. When you want to add new drives to these desktops, you may find that the computer cannot recognize the drive. There can be any number of reasons for this, and this tip, which is excerpted from InformIT, discusses many of them, and what to do about them. The original article on InformIT also discusses troubleshooting the same kinds of problems on other drives, such as SCSI and IEEE 1394.
Your computer can't prepare a new hard disk or use removable-media or optical disks until it recognizes the drive. Symptoms of a drive not being recognized can vary with the type of drive interface (ATA/IDE, USB, IEEE-1394, SCSI, parallel port).
The following are some typical symptoms:
- Internal drives aren't displayed at startup on systems that display configuration information
- SCSI BIOS on SCSI host adapter cards used with hard disks can't locate drive
- ATA/IDE BIOS on ATA/IDE host adapter cards used with fast, large hard disks can't locate drive
- Hard disk isn't displayed in drive preparation utilities like Computer Management (Windows XP/2000) or FDISK (Windows 9x/Me)
- Proprietary disk-preparation or disk setup programs supplied with IEEE-1394, parallel port or USB drives can't locate drive
The table provides a quick-reference to the most common reasons drives aren't recognized by the system. InformIT offers detailed solutions on their Web site.
