## Description

Internal Slim 9.5mm UHD 4K Blu-ray Drive for replacement and upgrade use. Warranty: One Year

Review: This is the drive for backing up your 4K UHD discs - If you've been trying to back up your UHD/4K discs, you have probably already found out that the BR drives you have previously used to back up your HD BluRay discs fail at least half the time. When I first got into UHD/4K, I tried using my trusty LG Electronics WH16NS40 drives to rip them. I'd ripped literally hundreds of BluRay discs with them without issue. Apparently, UHD discs are a whole different beast. I thought my old drives were failing. Reasonable assumption as I'd literally ripped hundreds of discs. So I bought a new pair of LG Electronics WH16NS40 drives and flashed them appropriately. Check out the makemkv forums, if you haven't already. Nope, same issue. I'd read that the BU40N is the gold standard for ripping discs. At twice the price of a normal BR drive, plus the cost of the drive bay adapter to house the drive in a standard PC case, it's quite an investment. By the way, you want the Icy Dock adapter, here: https://www.desertcart.com/gp/product/B0756MZTPG/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 After flashing the firmware appropriately, I can rip 4K discs with about a 95% success rate. Out of about 20 discs I've ripped so far I've only had one failure, which may or may not be due to the disc itself being damaged. So far I'm very happy with this purchase. Working great. Buy once, cry once.
Review: Works well, easy to flash firmware if needed - Out of the box it just worked. I purchased an external drive enclosure to put this in. I installed it in the enclosure, plugged it into a USB slot and in moments it was up and running. The viewing software I had on my PC recognized the BR disk and there was no issues. After verifying all worked well I flashed the firmware to be able to rip my own disks to my Plex system to watch in the house on various HDTV's. This is one of the models recommended on the makemkv forums. The seller shipped it in a sturdy box. Since this is actually an internal drive it comes with mounting screws and a replacement face front if needed. If flashing the drive, all I will say is read the instructions well on the forums as they can be confusing. I would absolutely by this again from this seller.

## Questions & Answers

**Q: Will this work on Lenovo Ideapad 330 and 320?**
A: If you are looking for a 4k dvd player for your laptop, most probably not.  Maybe Blue Ray movies. Those laptops are not fit to play 4k movies. It's not a fault on the player, or the software that you may be using.  It's on the Lenovo equipment specs. They do not accept systems that work with the HDR parameter.  Simply because Lenovo doesn't provide for it. You may use a regular 9.0mm dvd player and burner with them.

Hope this info can help you make your choice!

**Q: I have a dell precision m4700 will this blu-ray drive work with the dell precision m4700**
A: If your device supports 9.5mm slim drives this should work. The device manual should specify the compatibility.

**Q: Will this work with a dell inspiron w/win 10?**
A: If your device supports 9.5mm slim drives this should work. The device manual should specify the compatibility.

**Q: Will this work on a dell latitude 7404?**
A: It should, I'm using it on a dell Inspiron 7506, and it  works great.

### ⭐⭐⭐⭐⭐ Perfect fit for an old laptop! Works fantastic with MakeMKV
*by J***N on May 7, 2025*

Got this for my monster ThinkPad T440P specifically so I could watch BluRays on-the-go. Sounds like a weird, not-often scenario, but having the additional ability to use BluRay disks on something other than my desktop or PS4 is great. The drive is libredrive compatible, so it can be flashed to unlock the R/W speeds and other features for use with MakeMKV. I was able to confirm the drive works under Windows 10, Linux Mint and MacOS Ventura. VLC is able to open and play BluRays as well with the right settings! I will say the ONLY thing that I dislike about the drive is that it feels a bit flimsy compared to the stock CD/DVD drive from the T440P. Not a huge deal, just something you notice when opening and closing the tray.
