It did not brick the drive and appeared to work; however, I will express the strong caveat that is a dangerous operation.# hdparm -J /dev/sdddev/sdd: wdidle3 = 120 secs (or 13.2 secs for older drives) **Q: Is there any way to make these units turn on after a power fail w/o pressing the button? I tried the 3 sync modes and regardless of what the attached server does it seems I have to manually press the power on button to get these to start responding after a power failure (USB-3).** A: A comment to Abi and Phillip on chaining UPS units: I think the issue is total current draw, and usually if someone is adding another UPS, they plan to draw that much more current through the system, and that would indeed be bad. In general, it is good advice not to chain UPS or surge power strips, given how people normally just keeping plugging things in until all outlets are occupied. But... if Abi is disciplined and only plugs the one thing into that chained UPS that otherwise would occupy a plug on the first UPS, I'm not seeing the problem. Maybe Abi should tape over or toddler-plug the remaining outlets on the chained UPS as a reminder to avoid dangerous current draw situations? The total load on the first UPS then is almost unchanged (modulo the power overhead of the chained UPS itself), and if there is some reserve capacity on the first UPS, that shouldn't be a problem. Is there some other consideration I am missing here? **Q: If I install 4 x 4TB drives on this unit and connect it to my computer, I see 4 new USB hdds in my PC or just one big drive?.** A: If you just install the drives and power on, they will show up as separate drives. If you're using eSata, you can setup a RAID configration. (I use 3-3tb drives in raid 5) You can also use Windows Storage spaces to 'unite' the individual drives into one drive. Raid is faster though. **Q: has anyone tried putting a 2.5" 1 TB HDD in this thing? Do I have to use an 3.5" adapter or can I just plug in the 2.5" HDD?** A: Note: A Normal adapter/brace will not work that you would used for mounting a 2.5 in a PC case. The connections for the power and data transfer are fixed solid to the board in the back of the case. A normal adapter will leave the 2.5 drive well short of the connections and you will need to run cabled for the power and data, very very short cables. Additionally, the metal plate that functions to hold the drives in place will not fit snugly with the 2.5 drive adapter meaning it will float around in there just a little to make some noise. Due to these reasons I would suggest only using it for 3.5 drives as they fit perfectly in the drive bays. ## Frequently Bought Together - Mediasonic HFR2-SU3S2 PRORAID 4 Bay 3.5" SATA Hard Drive Enclosure - USB 3.0 & eSATA - Seagate IronWolf, 4TB, NAS, Internal Hard Drive, CMR 3.5 Inch, SATA, 6GB/s, 5,400 RPM, 256 MB Cache, for RAID Network Attached Storage, 3 year Rescue Services, FFP (ST4000VNZ06) - StarTech.com 4 Port PCI Express 2.0 SATA III 6Gbps RAID Controller Card with HyperDuo SSD Tiering - PCIe SATA 3 Controller Adapter (PEXSAT34RH) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/399774908-mediasonic-hfr2-su3s2-proraid-4-bay-external-hard-drive-enclosure](https://www.desertcart.tn/products/399774908-mediasonic-hfr2-su3s2-proraid-4-bay-external-hard-drive-enclosure) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-23*
