Question about ASUS M3A78-EM Motherboard

1 Answer

ASUS M3A78-EM stopped seeing second drive

I recently rebuilt my production box after several Seagate hard drive failures. Mother board is an ASUS M3A78-EM w/ an AMD quad core CPU running WinXP-x64. I upgraded to a 64 Gb SSD to dual boot XP & Win 8 (haven't installed Win 8 yet) w/ data & apps installed on a second Tb HD. Box has been up & running & today when I went to access e-mail, the app suddenly stopped & the window closed. The computer is no longer accessing the second drive. Is this an MB problem?

    IF I power cycle the box, not restart but stop/start, the second drive is recognized. Sometimes briefly, once long enough to do a complete backup of all drives.

SOURCE: sata/raid not working on ASUS M2N MB

You may need to set up the RAID array before it will be detected. Look in the BIOS and see if there is a way to set up the RAID array there. If there isn't, watch as the PC boots up and see if there is an option to go into the RAID settings before windows starts. You may need to actually create an array before it will be seen.

SOURCE: Recycle bin keeps filling up


Virus could be the cause of this problem. Try to perform system restore and observe if the error will go away or not. System restore, helps to reconfigure your computer back to the time when this error wasn't occurring.

To perform the restore, go to Start > All programs > Accessories > System tools > System restore.

Read the information on the system restore box before proceeding and follow instructions. After the system restore, the computer will be restarted.

If restoring doesn't solve the problem, please let me know so that I may direct you further on what next to do.

Good luck.

Open the case and check the connections to your hard drive. You may have a faulty cable to the drive(usually the data cable) on the other hand your hard drive may have failed. Also check you don't have a disc in the optical drive(CD or DVD). Make Sure The Power Is Off before you open it.

Asus Mother board M4n68T-M LE V2 not supported seagate 1tb internal hard disk

It should support drives up to 2TB automatically unless you are using an operating system older than Windows XP. If for some crazy reason the board is limiting you it may be a glitch that is fixed by upgrading your Bios. You can download the latest Bios for your motherboard here:

System boot problem

This is possibly a bad hard drive. If you know the manufacturer of your hard drive you can download diagnostic tools from their site, burn to cd and run diagnostics to check the drive for errors or failure.

I wanted to know whether ASUS A7S266-VM/U2 will support seagate 7200.10

M/Boards support all makes of hard drive
Are you sure you connected it correctly
The wide ribbon cable that goes in the rear of hard drive should
1) Be connected to M/board in the No 1 connector with the stripe on cable to the No 1 pin
2) the stripe on cable should go next to the 4 pin power plug on hard drive
Also ensure your BIOS is set to Auto detect of driives
