Solved Extremely slow HDD image from HDD to external USB 2.0 HDD

Specs: Windows 64, AMD
I will enclose here my complaint which I send to motherboard maker Gigabyte, regarding USB external hard disk problem. Please read it and if anybody knows how to solve this, thanks.My computer has 500GB external hard drive connected to USB 2.0 port(s), which is extremely slow. Drive is Transcend StoreJet. No drivers exist for it. It works perfectly for other I/O operations like copy, paste, delete,etc. When I try to make hard disk image with any program, and store it on Transcend Store Jet, speed starts with 50MB/s but drops to nearly zero in few minutes. It is the same with any program. Disk image would take more than one day to complete, if it completes at all. Actually, I never managed to finish image with any disk imaging software. I tried all usual software for that: Paragon, Aomei, Acronis, EaseusToDo, Drive XML, etc. Are there any USB or other drivers which are responsible for this issue? Can Gigabyte be serious regarding its costumers and provide them solution in order to use USB ports for most important thing (backup)? In this case, making disk image is totally impossible. USB 2.0 ports have theoretical speed of 480 Mbit/s. This is far cry from situation here. So, USB ports on this Gigabyte configuration is totally useless for backup on external USB hard disk. Clearly, there is serious bug which can cause loss of data - worst outcome in computer use for your customers. NOTE: all disks, internal HDD and external USB are checked multiple times and they do not have any errors. Hard disk has 500GB, only 137GB is occupied. USB HDD is empty. BIOS and Windows can see USB disks. BIOS is upgraded to version 5-maximum. It is on Safe Default Setting. Computer was in service few days ago and they did't diagnose any faulty component. Please feel free to ask me for further questions if needed.

Many external hard drives require more power than a standard USB port is designed to supply. Typically for these they either supply a Y connector so you can connect it to a second USB port for additional current or they supply an external power supply. I would recommend contacting the external Hard Drive mfg. to find out about this possibility as well as the possibility of a bad external hard drive. If the drive is working normally for small file transfers but not for large ones, it could be either the current draw is rising due to the constant high rate of the transfer or it could be that the external drive does not have sufficient cooling capacity to keep the drive itself from overheating (slowing it down, effecting the circuits, or increasing the current draw). You can prove this by wrapping it in a paper towel and then placing it between two cold packs (the plastic lunch box variety or medical variety) but NOT Ice (even in bags) and not linger than necessary to prove that it is overheating.
Another possibility if the disk proves otherwise good and working, try reformatting it to NTFS since most external drives are usually formatted to FAT32 to be more universally usable, and seeing of this makes the transfer easier.
Personally, I always build my machines with an extra internal hard drive in order to send my back ups and disk images to the secondary hard drives at SATA speeds and never need to remember to plug in the external on time for regular back ups.

Only because I don't see you post this I'll ask. Have you tried the drive on another computer?

It has Y cable. Temperature is usualy about 38C. Disk can't get to hot in 3-4 minutes. Here is report:

Have you tried the HD since ChkDsk ran and 'fixed' bad sectors?
Have you tried the HD on another computer?
Have you tried another USB cord to see if that one is faulty?
Do you have the higher current output (charging) turned on in your BIOS for the USB ports that many Gigabyte motherboards have? If so, it may work with a single USB cord that you may already have.
You seem to have assumed that the motherboard is at fault when it is more likely that the hard drive is at fault so that is what we need to investigate before assuming anything.

I did chkdsk /r on both drives.

This was for external one. I have Y cord for USB HDD. I'll try trick with current, I didn't know that. Where is that in BIOS (if I have that at all)? I tried 3 cords for HDD.

I have Y cable for HDD. I don't know if my Gygabyte can change current, I will check. Both HDDs are checked and they are OK. I changed 3 cords. Both are NTFS. External HDD is only warm, not hot. I will try imaging on my Linux machine.

"GIGABYTE On/Off Chargeā„¢ 2 for USB devices"
"GIGABYTE On/Off Charge technology is revised and upgraded on all GIGABYTE 8 Series motherboards, with comprehensive and enhanced charging support for a broad range of devices that include those that run both iOS and Android. Users can enjoy fast AC charging over USB on mobile devices, even when the PC is turned off."
But I believe that it was called something different on the generation before this.

I have that.
Does anybody have similar problem? And yes, there are bad sectors on Transcend. But what is interesting, right now I am performing regular backup on it. It goes well. Just to try.
