I have no idea what the answer is to your two questions. You need to ask the people selling the product. If they can't tell you, that tells you what will happen if you should have a problem later: nothing. The way Amazon works, as I understand it, people that sell products on Amazon live by reviews, that is, if you give them a good one, that is very good. If it is bad, they start having problems selling their products. Just ask them. If you don't know how/who to ask, ask Amazon. They really wish to help you.

I believe it is. I no longer have the unit. I had no problem with it. I used it with my HP Media Center PC. I do not know what the guarantee is, that's up to the seller. However, the 1st unit I tried I did not like and I returned it for a full refund. Sorry I can not be of more help. D.Winn, 7/2/2013.

I believe it works with USB 2.0. It is a great writer for the money and I use it a great deal to archive many things to help remove big data from my drives.

I bought this External USB Adapter about 3 months ago, I haven't been able to make it work yet

Some are and some are not. They usually indicate if a 3.0 is backwards compatible with 2.0 on the package or description. This particular USB 3.0 works with 2.0 as well and it has been working just well for me.

The drive is USB 3.0 based, and also 2.0 compatible, but the software that is delivered with the drive is complete trash. Just use it as a "normal" external drive with Win8 or 7, and you will have no problems. The DVD that comes with the drive is currently being used to keep the birds out of my fruit trees.

Mine came with a USB 2.0 cable. The difference is easily seen. USB 3.0 connectors have a Blue lip and USB 2.0/1.0 cables have a Black lip

Sorry, I made a mistake. The USB 2.0 read speed is 30 megabytes/sec and the USB 3.0 read speed is 255 megabytes/sec., i.e., bytes not bits.

No, it is a USB 2.0, however I purchased it for the internal Motherboard style USB slot. I needed an additional Internal USB and this card was a cheep option for that. It works great.

I maybe wrong but it looks like 2 USB2 in front and on the back. Never used USB3 before, so not exactly sure.So far, seems to work good

Yes. It is actually rated for USB 3.0. USB 2.0 is only a data transfer rate. 2.0 can transfer 480 Mbits/sec. USB 3.0 (which is what this is rated for) transfers up to 5 Gbits/sec!

This is USB 2.It will work with USB 3.0. I do not see any improvement in performance.

Yes it is. For small files, you won't even notice the reduced speed of USB 2 compared to USB 3.

All USB 2.0 devices are backward-compatible, but they will of course function more slowly.Buying and installing a USB 2.0 card in your machine may be a worthwhile investment.

Of course. USB 2.0 will never match 3.0 speed. When the drive worked read on 3 was at least 4 times faster

I really don't have any way to measure these things, other than simple observation. My experience has been excellent. Compared to USB 2, this setup has definitely, at the VERY least, doubled the USB 2. When using multiple ports simultaneously, I did not detect any slow-down. Install was easy enough, and the company's support has been very responsive. I needed to contact them because Windows didn't recognize the hardware. Highpoint offered a "dummie" driver to prevent Windows Device Manager from constantly displaying a warning that there is something wrong with a device. The device works very well, and I have never experienced any problems with it. I hope this response helps you!

Hey, I am using this product usb 2.0 over an year. I bought one more flash drive 3.0 for my mom. It works great for me. You might have the defect in product. Ask seller to replace as this one is weird issue you described. You might wanna give a try to format the usb drive and then see if problem still exists. If yes then ask seller for the replacement.

It works with USB 2.0 at 2.0 speed. But its worth it because of the future proofing aspect. 3.0 is much much faster. Hope i helped.

I am looking at the box that the keyboard came in and I don't see the word "certified" anywhere associated with USB 2.0. Now, that's not to say it's not a USB 2.0 device. Why don't you go to Macally's website to get the question answered by them, if its that important to you before you purchase the product.
