Delayed Write Failed error on USB hard drive

"If you've tried with various USB cables, and the same exact problem occurs on different machines, it's almost time to consider that the device is a) broken or b) poorly manufactured, and not effective.

If you decide a) is likely, take it back to the retailer and exchange for a new one.

If b), take it back to the retailer and ask for a refund, then use the money to buy a different product.

This is not to say there isn't a software solution (maybe there is), but your ability to exercise options a) and b) is somewhat time limited. To my mind, this sort of operation on a modern device and modern computer should just work, and the likelihood of a built-in problem in the device increases with every computer it doesn't just work on.

Before giving up, though, you should:

check for updated drivers or device firmware from the manufacturer;
search the manufacturer's support knowledge base for this error, to see if there's a simple fix; and
test the device on as many computers as possible, with as few other USB devices as possible (to eliminate the possibility of USB bus congestion).

Just know when to give up and take it back for something that works."

"I had a similar problem on a vista machine where the drive generally worked but anytime I tried to copy a large amout to it it failed, no error message drive just disappeared. I also had problems where when I first plugged it in it would just click click click and not come online.

I turned of ""index this drive for faster searching"" and it works fine now. Right click drive, properties/general bottom of page."
