Seagate Expansion 12TB External Hard Drive HDD - USB 3.0, with Rescue Data Recovery Services (STKP12000402)

EXCELENTE DISCO DURO

I needed this since my 8TB was almost full, I'm loving it.

Gets the Job Done. Very stable. Plug and play. No problems at all.

I'm writing this because of all the reviews I see complaining about the drive not showing up on their computer initially, saying "it doesn't work right out of the box!" I often wonder if some of these people never even read the documentation before giving up. The included documentation for the drives is horrible, with only a Quick Start page that shows how to plug it in, but there is great info on Seagate's site that helps if you go look at it. There's also something else I found out that might be helpful, and I'll address that here. Once I've had it in use for a while I'll update this review for a more in-depth account of how well it works. I'll list my comments by issue:1) Drive not getting recognized.After seeing so many "it doesn't show up" comments, I was concerned when mine didn't show up on my iMac either. I followed the instructions on plugging it in (in sequence, which may or may not make a difference, but you gotta do it correctly just in case), and the first thing you have to do is decide which US Standard plug to slide onto the universal plug adapter; there are two that are almost identical, two-prong plugs; one has holes in the prongs and the other doesn't. Docs say nothing about which to use, so I went with the one with holes.The unit powered up and sounded like it was initializing, but it wouldn't get recognized by my Late 2017 iMac. Unplugging and restarting did nothing. I went to the online documentation and did the recommended check to see if Show Hard Drives was checked in Finder/Preferences/Show-Hard Drives. It was (which I already knew because my others show there, but just in case I needed to recycle the command...). That did no good. After a bit of thought, I decided I'd try the other plug, and that did the trick. USE THE PLUG WITH NO HOLES IN IT if using in the US!Once that was solved, it showed up and all looked good.2) Using with Time Machine on Mac.The info in the product description says the drive is ready to use with Time Machine, preformatted. The problem is, if you have Catalina or later, there is a new formatting called APFS that replaces xFat, and you will have to reformat to use with Time Machine. This is a simple process using Disc Utility, and it reformats quickly.Once I had that issue solved, I got Carbon Copy Cloner (trial version) and set up the tasks of copying my main hard drive (348.3 GB) and my 8 TB external drive to the new Seagate drive and let it go. The main drive was backed up in just over 47 minutes. Yeah, it's a tad noisy, but nothing that can't go on while working on the computer by any means unless you're maybe recording a YouTube video at the computer or something.The external drive, which had 6.58 TB of stuff on it took a little longer... 12 1/2 hours to be exact. Slow? I don't know, it's the first time I've copied a hard drive with that much stuff on it, but I set the task and left it alone and it was done in the morning. The image included here shows Carbon Copy's review page for the performed tasks.CAVIAT: you may need to use a program that allows the computer to work without shutting down after a period of inactivity. I use an app called "Amphetemine", which forces the computer to stay on in various circumstances that you can set. I set mine to remain on "as long as specified app is working" and chose Carbon Copy Cloner. Not sure you have to do this, but Amphetamine is a great app and I didn't want to take the chance of having to start over, so I used it, and it worked great.The noise some complain about could be other drives (I have the 12 TB version for desktop) or it may be a personal preference, but a drive in a plastic case like this with lots of air holes in it will make some noise, however I didn't find this "noisy" at all IMHO.So far, I'm impressed with Carbon Copy as well, but like the drive, I'm in my infancy with using it, so time will tell. I also have a 1 TB external I use for Time Machine, so instead of using this one for that, I will most likely also set up the drive to copy that drive so I have a backup of my Time Machine just in case. You can set Carbon Copy to copy whenever it detects a change in a drive, so once the initial copying is done, the lengthy copies are done, and it's only copying when things change.If you have issues with one of these drives not being recognized by your computer straight out of the box, FIRST make sure you have the correct US plug installed. THEN, make sure to reformat to APFS if you're running Catalina or later if you plan to use it for your Time Machine backups. At that point, so far in my experience, it's a great drive. I'm giving four stars only because of having to hunt down good documentation for the actually necessity for reformatting for the OSs, and for having NO information about the right plug to use. NO idea why the one with holes won't work, but it would be nice if they gave a heads-up on that.Once it's been working a while, I'll readdress this review.

I bought this drive (10TB version) to use as a media storage device for my Plex server. I run my Plex server on an older (2013) apple iMac that is running MacOS Catalina. When I first unboxed the drive, it looked nice, but when I plugged it into the power and then the USB on the back of my computer, it wouldn't show up. I couldn't get it to show up in my Finder window, on my desktop, or even in Disk Utility. I did all the tricks to show all drives and all volumes, but it just didn't even recognize that it was plugged in at all. I read some of the other reviews, lots of people complaining about how it wouldn't work on their mac etc..., I thought that maybe I was going to have to return the drive and figure out something else (it comes preformatted in exFAT, but as I said, MacOS Catalina wouldn't even acknowledge it was plugged in at all, so there was no way for me to reformat into the the system I wanted). Luckily I had a Mac Laptop with BigSur installed. On my laptop, it didn't show up in Finder or the desktop at first, but it did recognize it in Disk Utility (again, you have to set it to show all drives and volumes in the view). There I was able to select it, then reformat it as MacOS Journaled (or whatever file system you wanted, but that is what I use on my older Mac). Once I did that, I was able to plug it into my older Mac, and it showed up in Finder, Desktop, and Disk Utility. I actually reformatted again on the old mac (just to be safe, but probably not really needed as it was reading, I just wanted to make sure it would work on the old mac the way I wanted it to). As I'm typing this, it's just finishing backing up the 4TB of media from my old drive, it's been whirring away for about 24 hours now, no problems so far. So as long as you are willing (and have the newer macOS available), then this is a great external hard drive for Macs, just don't expect it to work natively right out of the box (but external hard drives rarely do). That being said, I am happy with the price and performance so far, hoping 10TB will last me quite a while (my old drive was 6TB and I thought I would never even come close to filling that up, but I don't like to run my drives too full, so using 4TB out of 6TB was more than I liked, so this 10TB should fit the bill nicely for a while anyway).

I bought this drive to hopefully rid me of one of my two, 8 tb hard drives. At the very least free up some space. The moment I got it it was making some distinctly but alternatingly different sounds that did not sound like a hard drive should? Anyone familiar with the old Maxtor grinding noises will know what I mean.At first I thought that is just how this drive must sound. As someone that has been building computers since the 90's I'm aware technology changes and sometimes in unexpected ways. But as I transferred files the drive not only got slower but it got louder. It took me five to six times longer to get all my files off the drive and back onto my other drives before it died completely. I only had the drive for a week and not only did the noises (I can only equate to taking a record needle and tapping on a record that wasn't spinning) get stranger and louder but the drive took longer to transfer files and got more and more erratic coming out of sleep mode. I love both Western Digital and Seagate but in this case I am willing to say I just got a bad one as this is more than possible. I personally have not checked on the actual technology that is in this drive but until I do I had to go with a reliable drive I know the technology in better. I would advise if you get one that takes a long time to come out of sleep mode and makes strange taping scratching noises speraticly, send it back for a new one. I won't blame Seagate for this completely I just know I got a bad one out of the box.
