Question about BYTECC BT-PESAPA / 2-External SATA, 2-Internal SATA & 1 PATA / RAID 0, 1, 0+1 and JBOD / PCI-Expre (BT-PESAPA) Storage Controller

1 Answer

I put a BYTECC BT-PSATA esata controller on an old dell desktop system, and it installed fine, looks like a VIA RAID Controller - 3249 to device manager. But when I attach a 500G external drive to the card, the system hangs completely - mouse won't even move - when I detach the disk from the controller, the system wakres up again. If I try to boot with the disk attached, the boot hangs when XP is trying to load - again, take the disk off and things wake up.

    The drive works fine on a modern laptop with an esata port.

    I never heard that a large drive could cause an older desktop to freeze. why would that happen?

    The old desktop has Pentium III 748Mhz, 768MB RAM. If RAM is the bottleneck I can try to add more.

    Thanks for your advice.

its either the external hard drive case (or hard drive itself) is defective or the hard drive is too large for your computer. What's the configuration of your computer, I mean, Ram size and Processor size?

If the external hard drive is too large for the computer, it can cause the computer to freeze/hang.

You can connect the external hard drive to another computer or laptop and observe if it will do the same. This will reveal if the problem is from the external hard drive or computer.

Good luck.

    Since you have not heard that large drive can make a old desktop size, then you are hearing it for the first time. I'm saying this out of experience.

    Hard drive capacity has to be equal to the size of RAM and processor of a computer. This is why you see that modern computers has about 2G to 3G of RAM and double processor of about 2000+ on each processor.

    Pentium III 748Mhz, 768MB is to small for 500GB.

    Try upgrading your RAM, it might help a bit.

    Good luck.

How do i find out the manufacturer of my coprocessor, raid controller, and my sm bus controller on my desktop running windows vista

Start>All Programs>Accessories>System Tools>System Information

Why do you need to know the manufacturer of these devices?
Error code 28 means the drivers are missing. A hard reboot could fix it. A virus scan could fix it (use malwarebytes free version).
Your bigger problem is Windows Vista: one of the worst operating systems ever put to market. I would suggest backing up all of your data, then do a clean install of Windows 7.

Problem using VT6421 card as extra IDE port. I

First, you have to know if all driver components is installed in your computer, I'm talking about your motherboard make sure that all the drivers is installed.
View the status of your device driver.

If you are using Windows base Operating system like Windows XP open this menu:

Start Menu > Control Panel > System icon > go to Hardware tab > click Device Manager

Look for the question mark, it indicates a not working device.

VT6421 is a Serial Raid Controller

Refer to the product specification of your motherboard, view this site:

Download and install the Device driver for The Raid Controller of your Motherboard

Boot from non Dell raid controller

Check the Boot Sequence again -- if there are any "SCSI" devices listed, enable them, and make your CD-ROM the "primary" boot-device (so that you can install Windows) and make this "SCSI" device the SECONDARY boot-device, and disable the internal hard-drive, so that it won't be used as a boot-device.

I put 2 disks in raid 0 array on this controller

When you say "after merging the driver via a floppy at the txt setup" I think you are referring to pressing the F6 key to load the raid drivers. But I don't understand "restarting setup".
You will need the correct XP64bit drivers loaded on a floppy for this to work.
Maybe a good place to start is a temporary install of XP using 32bit drivers to prove all components are working.

Can't get sata connection to work on new blu-ray rom

Oilers5, let's check a few basics first. Double check your dvd's data & power connections first. Everything good? Next, you need to get into your bios. Your blu-ray is connected to the SATA controller on the motherboard. Though I do not doupt the device manager your bios must see the device before windows will. At the main menue in your bios the DVD player should be listed (depending on model # of board) at the main menue. Than make sure the SATA controller is enabled, you'll find this in advanced menue. This is where you'll need your manual. If the dvd is the only SATA connected to the system you should have the option to use the SATA & not the RAID. If you have SATA hard drives connected & your dvd ends up on the RAID end you still should have the option to set the RAID to IDE. This way you will not need to run the RAID software. Once you get the bios adjusted windows should see the blu-ray as a SATA dvd player.
Oilers5 if what I have listed has not helped or fixed your problem could you post back with your model no# of the motherboard. Mfg's name ex; (dell, HP...). Than I can download your manual & check what settings need to be adjusted. Is this the only SATA device your trying to get to run? Is your current hard drive a SATA or IDE? How many?
Thanks Oilers5. I look forward to your next post.

M7NCD ULTRA raid drivers

If the SATA drive is operating in 3.0 Gbps mode and your motherboard can only support 1.5 Gbps mode, the drive will not be detected in BIOS or XP. Try jumpering the drive to SATA 1.5 Gbps mode. The label on your hard drive should indicate which pins should be shorted to achieve this setting; if not, look up your particular model on WD's website to find the manual.
