Hi,
My laptop has a 128gb nvme ssd which has the operating system on it and is the C drive, and a secondary 1TB seagate hdd (st1000lm035) which is the D drive. The D drive boots fine but after a random period of time will disconnect and won't reappear until restart.
I have run crystal disk info which says caution and says the problem is with reallocated sectors count (says 96 current, 96 worst, 36 threshold. not sure what these numbers mean) but all the other things are blue rather than the yellow caution. Running a seatools test seems to pass the short generic test and the smart test but when running a long generic test, after some time the D drive will end up disconnected which means it fails the test. Running a chkdsk has been successful once but usually has failed(when the drive disconnects), I've tried letting it repair the drive on boot rather than with the drive unmounted but both have resulted in the drive disconnecting, usually the chkdsk gets stuck at a certain percentage and then the drive disconnects. The drive appears in bios, it usually works fine on boot and then after some time will disconnect meaning I have to restart again. The fact it works fine at boot means I have been able to backup my data(although I had to do this in multiple efforts as it would usually disconnect mid file transfer). When it disconnects, going to disk management to try and get it to recognise the disk again does not work. The drive appears in the hidden section of device manager when it ends up disconnecting. I've tried uninstalling the driver on device manager and rebooting and it still hasn't changed a thing. Over the past few months i would occasionally get a notification that I needed to restart to repair drive errors which were related to the D: drive (I think there are some corrupted files or something), though the drive never stopped working and I presumed chkdsk had dealt with those problems. I'm not sure what to do, I've ended up buying a 2.5 sata ssd in case I need to replace the hdd but before I open the packaging I'd like to confirm that the hard drive is indeed failing.

Any assistance would be greatly appreciated.

Your Seagate HDD is starting to fail. It needs to be replaced What Is the Reallocated Sector Count Warning and How to Fix It
Thanks for the reply. I was informed that the values I provided arent the relevant ones and what actually matters is the "raw value" which is usually presented in hex, I changed it to show in decimal and the raw value is 3032. I'm assuming thats quite indicative of a failing drive so I will be replacing the drive once I figure out how to deal with this stripped screw I have on the bottom of my laptop. Interestingly enough, I just tried running a smart check on SeaTools which passed, and then a short generic test which failed after getting stuck at the "random read" section and then the drive disconnected.

You need to have a backup NOW of anything important on that drive!
Hi, thanks for the concern but as I mentioned in the original post i've already backed up what i need from the drive so I am free to troubleshoot before I replace it, although there seems like there isnt much troubleshooting that can be done.

Believe what you want, But Bad Sectors are like Cancer. Once they start appearing, it is just a matter of time before they spread and the drive is useless. If any HDD Diagnostic Program shows Caution, the drive is beginning to fail. It has a little life left in it, but it is about to fail at any moment. It's better to be proactive and replace the drive now before it is a Catastrophic failure

I've replaced it with an SSD now and everything is fine, I appreciate the help.
Just a quick question someone may be able to help with. Windows still lists some programs that were installed on the old drive and won't let me uninstall them from the control panel because it can't find the uninstaller. I assume this has to do with the leftover registry stuff from the old programs. Is there an easy way to get rid of these?

Glad to hear you got a new drive and it is all sorted.
You can attach your old drive, if it gets recognized by the computer, and go into the X:\Program Files or X:\Program Files (x86) where X: being the new drive letter for the old drive, and open the program folder and use the uninstaller. Or you can download Revo Uninstaller. Use Hunter Mode and drag the target onto of the files or shortcuts to remove the remnants of the program
