My Seagate Backup Plus external hard drive suddenly stopped showing up on my Windows PC, and I need help recovering important files. I’m not sure if the drive is failing, corrupted, or just has a connection issue. What are the safest Seagate Backup Plus recovery steps to try without making the data loss worse?
First thing: stop using the Seagate drive for now. Don’t copy anything to it, don’t run repairs on it, and don’t format it if Windows asks. If files were deleted or the drive has turned RAW, the data may still be sitting there, but the drive space can get reused if the system writes anything new to it.
Do a quick check before trying software. Listen to the drive. Clicking, grinding, or a loud spinning/whirring sound usually points to a hardware problem. If that’s what you’re hearing, recovery software probably isn’t the right move. Check Seagate’s Rescue Data Recovery Services first, since some Backup Plus drives include a couple years of coverage with the warranty. Use the serial number on Seagate’s site to see what applies.
If the drive sounds normal but doesn’t show up in File Explorer, or Windows says it needs to be formatted before use, that’s more likely a file system issue. Annoying, but better than a dead drive. The files may still be there, while the part that tells the computer where everything is has gotten damaged.
For handling this yourself, I’d use recovery software rather than trying random Windows fixes. For Seagate Backup Plus drives, Disk Drill is a solid choice, especially when the drive shows up as RAW after being unplugged badly or not safely ejected.
Here’s the safer way to go about it:
- Install the software somewhere else. Don’t install Disk Drill, or any recovery tool, onto the Seagate drive you’re trying to recover from. Put it on your main C: drive or another external drive.
- Make a byte-to-byte backup if the drive is unstable. Disk Drill has a Byte-to-byte backup option in its extra tools. If the drive is acting flaky, make a disk image first instead of hammering the physical drive with a long scan. After that, unplug the Seagate and scan the image file.
- Use a good USB cable. If you scan the drive directly, try a reliable cable. Sometimes the original Seagate cable is the actual problem, which makes the drive look worse than it is.
- Scan for lost data. Pick the Seagate drive in the software and start the lost data search.
- Preview before recovering everything. If the preview works for a photo, document, or whatever you’re trying to save, that’s a good sign the file is recoverable.
- Recover to a different drive. Never save recovered files back onto the same Seagate drive. Use your internal drive or another external with enough free space.
If the recovery program doesn’t show the drive, open Disk Management in Windows. If the drive appears there with the right capacity, like 2TB or 5TB, recovery software may still be able to read past the damaged file system and pull files from it.
After you get the data back, don’t trust the drive right away. Download SeaTools from Seagate and run the Long Generic Test. That checks the drive more thoroughly for physical problems. If it fails, replace the drive. If it passes, you can format it and reuse it, but I’d still keep another backup somewhere else.
Large drives can take a long time to scan, so don’t be surprised if it feels slow. If the drive is still spinning normally and shows up with the correct size, there’s a decent chance you can recover a lot of it.

Don’t click “Initialize disk,” don’t run CHKDSK, and don’t assign a new partition thinking it will magically fix it. Those are common Windows suggestions, but they can make recovery messier if the partition table is damaged. I agree with the general idea above about checking whether the drive appears with the correct size, but I’d check that in Disk Management before spending hours scanning. If it shows as 0 bytes, “No Media,” or keeps disconnecting, stop and treat it like a hardware issue. If it shows the real size, then recovery software like Disk Drill has a fair shot, but recover to a totally different drive. The boring stuff matters too: try another USB port directly on the PC, no hub, and another cable if it’s the removable kind. A bad cable can look exactly like a dying external drive.
A drive showing up under Device Manager does not mean Windows can actually read the disk. That only proves the USB device answered at some level. The more useful question is whether the actual drive shows in Disk Management with the correct capacity.
For a Seagate Backup Plus, I’d separate the problem into three layers: cable/power, USB enclosure, and the drive itself. People often jump straight to recovery software, but the enclosure or power adapter can be the failure point, especially on the larger desktop Backup Plus models that use a separate power brick. If it is a 3.5-inch desktop unit, try the correct power supply and listen for spin-up. If it is a portable 2.5-inch model, try a short known-good USB cable plugged directly into a rear motherboard USB port if you’re on a desktop PC. Front panel ports can be flaky with drives that need more power.
Do not open the Seagate case as your first move. That can mess with warranty or Rescue coverage, and some portable external drives are not simple SATA drives inside anymore. On some models, the USB board is part of the drive setup, so “just remove it and plug it into SATA” is not always the easy fix people make it sound like. If the files matter a lot, checking the warranty/rescue status before cracking anything open is the smarter path.
The quick test I’d do before scanning for hours:
1. Try another USB port and cable.
2. Try another computer if you have access to one.
3. Open Disk Management and look only at size/status.
4. If it shows the real capacity, do recovery or imaging.
5. If it shows 0 bytes, No Media, unknown size, or drops in and out, stop treating it like a software problem.
If it shows the proper size but says RAW or asks to format, then tools like Disk Drill can make sense. The important caveat is that a full scan is stressful on a weak drive. If the drive is slow, clicking, vanishing, or making Windows freeze when connected, I would not keep retrying scans. Make an image first if the software can read it, then scan the image instead of the physical disk.
Another thing people forget: Windows may hang because Explorer is trying to read thumbnails, file metadata, or the broken partition. So don’t judge the drive only by “File Explorer freezes.” Disk Management may take a minute to load too. Let it sit briefly, but if the drive keeps connecting and disconnecting, unplug it. Repeated reconnects are not harmless when the heads or media are failing.
If you already clicked Format but used quick format, that does not automatically mean everything is gone. A quick format usually removes file system records rather than overwriting the whole drive. In that case, stop using the drive immediately and scan it as a lost partition/formatted drive. If you did a full format or copied new files onto it afterward, recovery gets much worse.
My practical cutoff would be this: if the drive contains irreplaceable stuff and it makes bad mechanical noises, don’t DIY it. If it sounds normal and Disk Management sees the correct size, recovery software is reasonable. If it is somewhere in the middle, unstable but still detected, image first and scan later. The worst approach is trying five repair commands, then three recovery programs, then formatting, then asking why the folder names are gone.
A password-protected Seagate can look “recoverable” but still give you useless results if it isn’t unlocked the same way it was before. If you ever used Seagate Toolkit/Secure or set a drive password, try unlocking it on a known-good PC before scanning with Disk Drill or anything else, because raw recovery won’t magically decrypt the files.
