Expansion 12TB External Hard Drive HDD - USB 3.0, with Rescue Data Recovery Services (STKP12000400)

My only issue was that after I copied all my backup files to the disk after the seamless plug-n-play, I rebooted my computer and the exFat format on the disk caused my reboot to hang up on the manufacturer's logo. I contacted Seagate for support and they did not realize the issue so were having me test on other machines and the cord, etc. Lots of time to do all that troubleshooting. Found my answer by searching that someone had reformatted from exFat to NTFS and solved the issue for them. So, I erased all the work I did and reformatted and it booted right up. Seems to serve it's purposed to hold backup files quickly and easily. The one I'm replacing is a Seagate and have had for years and still works. Just too small at this point. I'll repurpose.

Bought this as a christmas gift for my boyfriend. Came sooner than expected!

This wouldn't load on my Mac with the latest OS and everything updated. So I returned it for another. The new replacement made loud clanking noises within the hard drive and again wouldn't load on my Mac OS. There's something seriously wrong going on with Seagate's quality control. Staying away from all their products from now on.

decent speed. does not have on off switch

Maybe it's just me, but 2 WD drives have failed while my other Seagate is still error-free. I chose this to replace my latest WD failure. To be fair, my drives are pretty old and drives can't be expected to last a very long time, Still I choose to go with the brand that hasn't yet failed. This one 12TB is quiet and competitively priced.

I purchased the Seagate Expansion 12TB External Hard Drive earlier this month, excited to add a large-capacity drive to my setup. However, upon receiving the product and setting it up recently, I discovered that the drive only provides 10.9TB of usable storage. I understand that drives rarely offer the full advertised capacity due to formatting and pre-installed manufacturer software. However, a loss of 1.1TB—nearly 10% of the advertised space—is far beyond what I consider reasonable or acceptable. For a product marketed as providing 12TB of storage, this discrepancy feels misleading. Customers rely on advertised specifications to make purchasing decisions, and when those expectations are not met, it damages trust. I hope Seagate (or Amazon) will address this issue transparently, whether by improving accuracy in their marketing materials or minimizing unusable storage in future products. While Seagate drives typically perform well, the significant shortfall in available storage makes it hard for me to recommend this product without hesitation.

Have used this brand for years. Reliable. Extra storage is nice for back up file.

It worked until it didn't. We have this paperweight sitting in front of me that stopped working and now we lost everything that is on this device. We have not been able to get in touch with Seagate since this broke immediately after the return window closed. We are disappointed.

Prima. Weinig geluid is niet nas versie intern.

12TB を購入しました。外付けHDDなので中身が気になっていました。 ヘリウムならIronWolfでもなんでもいいと思っていましたが。 CrystalDiskInfoでST12000NM000Jが表示されたので、EXOS！なんか得した気分です（笑）

Chegou o produto certo, funcionando, no tempo previsto e muito bem embalado. Parabéns.

Le processus est en arrêt constament, juste pour ajouter un nom de fichier. Alors imaginer pour le reste, il bloc tout les processus de l'ordinateur et on n'a pas le choix d'attendre 2 à 5 min pour qu'il réponde

Super happy with this purchase - the drive inside is ST12000NM002H-3KX133 which is a Exos X24 series
