Perfect fit for the Acer Aspire 5742. Even the original fascia fitted perfectly to this drive, including the eject button lining up with the switch. Undo the single screw on the base of the laptop, and slide the old drive out. Remove the two screws that hold the little metal bracket to the end of the drive, and fit it to the new one. Using a flat bladed screwdiver, carefully pop out the fascia from both drives. There is a clip on the side and another under the flat edge on the other side. Clip the old fascia to the new drive, and push the new drive into your laptop. Replace the single screw in the base. Switch on. Windows should take care of the driver by itself, and you should be able to watch those DVDs again. I can't comment on the longevity of this drive yet, but I reckon it will outlast the now old laptop.
Replaced the Toshiba Samsung cd-rom on my Dell OptiPlex 755 small form desktop computer so I can burn cds and dvds. Took minutes to install once I found a small enough screwdriver to refix the bracket. I just measured the old drive to check dimensions were same (pretty standard I think). Windows 7 installed effortlessly. Visually it looks like it was built in, the outer facia exactly same size, and it works beautifully. It's only slightly noisier in operation than the fan in my computer, no issues with that at all. Excellent product.
Bought this Pioneer drive to replace a faulty Toshiba/Samsung drive, which sounded like it was choking when trying to read discs and eventually refused to write to disc, It's certainly alot quieter than the Toshiba/Samsung drive, I don't understand how another reviewer is saying it is noisy, to me, it's almost whisper quiet and does not choke at all when it gets going. If anyone is looking a burner to replace the broken factory installed drive, I would recommend this.
Good price, nice unit, as i have some RAM discs i needed this unit for these. placed it in a external caddy as i'm using it on my iMac, works well. and build date was with in 2 months of the unit delivery. 10/10
