BIOS 抓 不到 硬 碟

當你的 BIOS 無法檢測或辨識硬碟時，可能會令你感到擔憂。更糟糕的是，這個問題有多種導致的原因，因此很難確定你的電腦 BIOS讀不到硬碟的確切原因。幸運的是，你可以使用一些技巧來找出導致此問題的原因。接下來，我們將介紹如何解決 Windows 10 中無法識別硬碟的問題。你只需按照以下快速修復和有效解決方案來修復 BIOS 錯誤中未檢測到/識別硬碟，並使其顯示在 PC 中並立即重新工作。

For ATA drives, Seagate recommends using UDMA cabling with a maximum length of 18 inches. UDMA cables have colour coded connections which require proper orientation when connecting.

• Blue connector - always connects to the motherboard.
• Grey (middle) connector - is used for slave devices on the cable.
• Black connector - is used for master device connection.

1. Drive is not spinning up
   If the drive is not receiving power or receiving an incorrect level of power, it will not spin up. To check to see if this is the cause of the BIOS not detecting the hard drive, follow these steps:
   1. Power off the computer.
   2. Open the computer case and remove the data cable from the hard drive. This will stop any power saving commands from being sent.
   3. Turn on the system. Check to see if the hard drive is spinning. If you touch the side of the drive you should feel a slight vibration. If you do not hear or feel the hard drive spinning, the drive did not start.

If you cannot determine whether the drive is spinning:

1. Boot the computer and listen carefully.
2. Shut the computer down.
3. Disconnect the power cord from the computer itself.
4. Disconnect the power cable from the hard drive in question.
5. Reconnect the power cord to the computer itself.
6. Boot the computer up to see if the drive sound was audible before. And,
7. Then repeat, only reconnect the hard drive and listen for it to spin up.
8. Switch power cables with a device like a CDROM or DVDROM drive, so that you are using a known-good power cable.
9. Check the power supply on your computer to determine whether it is providing sufficient electrical power to operate the drives and devices you have in your computer.
10. If the drive is still not spinning, connect it in another computer if possible.
11. Connect the drive in a SATA-USB enclosure or something similar if possible.
12. If the drive does not spin up after all of these steps, please visit the Warranty page to begin a warranty replacement order.

1. Incorrect jumper settings on the drive

ATA:  It is recommended that all Seagate ATA hard disks supporting the Cable Select jumper option be configured as Cable Select. If your computer system was built prior to October 1998 and does not support UDMA 66 or greater you will be required to use the Master/Slave jumper settings.

When using Cable Select jumper settings on your ATA drive, all devices connected to the UDMA cable must also use the Cable Select setting. The cable decides master/slave device detection when the cable select jumper settings are used.
