Question: Hi,I have a Dell E6400 laptop with an HL-DT-ST CDRWDVD MU10N optical drive installed.  Can I replace it with the UJ892?
Document: I bought this intending to replace a failed DVD drive for a Dell Precision M4400 with a slim-line modular bay (similar to what is on other Dell models), which allows easy swapping out of a DVD drive for a hard-drive caddy or 2nd battery. I discovered on arrival that this item was intended to be installed permanently.
not much to say here it's an optical drive for your laptop. If you are ordering it you probably know how it works
Where it did not actually fit my dell as I had expected (originally designed for a laptop), the DVD drive did function as expected and has continued to function as expected. I just wish there was more detail given as to the dimensions of this drive verses others. This one is slightly narrower that my original drive and I could not interchange the faceplate with my old DVD drive. I will be forced to make some modifications to the front of the tray if I were to consider installing my original faceplate.
I needed a slim sata optical drive for a server that did not come with one. Hung this on the end of a sata cable and got on with it.
This says Genuine and it is not. My Dell e6400 has a drive with a latch that holds it in place. This drive does not have that. I kept the drive because it does fit in the slot and does work. I removed the bottom cover of the notebook and used Gaffer tape to hold the drive in. I loan the computer out to employees and the drive must be secured. Without the latch this is the only way I could hold it in place securely.
plugged it in and it worked. shipping was quick and I was able to repair my daughters laptop. Product was as advertised.
from all I read this should have worked. It might have if it had not been ultra slim. So now I have a drive I cannot use. Arrived as told. Good price
The drive functions as advertised. I am not pleased the description did not identify the actual drive height. The drive was used in a SilverStone case and not one listed in the description.
I removed the bracket (which was preventing the drive from going all the way into the slot) and it worked. Doing things this way means that a) to remove the drive, I need to open the drawer and pull it out that way, and b) the drive might conceivably slide out when moving the computer. However, I don't plan to leave it in normally, since I normally have a second hard drive in there. So, these problems are minor inconveniences for me.
What I got was a Lenovo ultrabay slim dvd multi that does not fit my DELL and what it was described will work with.
Answer: Yes, I had a Dell Latitude E6500 and it works fine.  Two problems, however.  First, the cosmetic faceplate from your old drive will not fit the UJ892.  The faceplate that comes with the UJ892 is flat, not sloped so it doesn't match the case profile correctly.  I don't think this is a big deal.  Second, and more importantly, the UJ892 lacks the mechanism that locks the drive in the case (and the tab that springs out so you can pull the drive out).  I've had it fall out when moving the laptop around.  No damage but a bit disconcerting.  There is another drive that is equivalent to the UJ892 but includes the drive latch.  Unfortunately, I don't remember what is is.  But I found it originally just by search around the web.  Sorry, I can't provide.
