February 18, 20215 yr I was in the middle of using my computer when the entire house lost power. I have an external USB HDD connected to my computer. I get quite nervous when this happens. What is the necessary steps I should take when starting up my PC after a power outage? Do I need to run some commands to check/repair the SSD/HDD from any potential damage that may have resulted from the power going out? I run Windows 10 Pro.

February 18, 20215 yr I have never had any data loss due to power outages. Happened on a couple of occasions and I just restart the computer when the power returns. But for some peace of mind I guess you could check with, for example, Crystaldiskinfo..? Richard 7950x3d | 32Gb 6000mHz RAM | 8Tb NVme | RTX 4090 | MSFS | P3D | XP12
February 18, 20215 yr I run a 4TB USB3 SSD external storage and backup drive and have never had a problem and it has happened more than once, my computer room is on the upstairs ring if it trips all the ring plugs drop power. I have had a hairdryer trip it an iron and a portable lamp the circuit breaker just trips. Raymond Fry.
February 18, 20215 yr More than likely you're OK. Problems can arise, though, if a write to the drive was in progress when the power failed. I'd just try booting up normally and keep your fingers crossed. Usually I would recommend running chkdsk /f on the drives after a potentially serious anomaly like that, but right now before even thinking about that you have to make sure you have the latest Win 10 update that fixed a serious problem that could make your system unbootable when running chkdsk on an SSD. Unfortunately, that same update boogers up the sound system and causes sound dropouts on some systems (like mine). Oh, and put your system on a UPS...that would have prevented your even having to worry about this.

February 18, 20215 yr I have probably lost more PC power supplies due to power outages and spikes versus having loss or corruption on hard drives. Either way, a UPS is the best protection for a scenario where power isn't 100% reliable. NTFS file systems do protect against some data loss. Was more worrisome back in the days of FAT/VFAT/FAT32 file systems. Edited February 18, 20215 yr by mattn

For your system (high power consumption) I would recommend to buy an UPS, but something above 2,000 KW capacity. Mine's 1,500 KW and in a recent power outage did not worked as expected and the computer went out too. It's scary when that happens, but what I do is to make sure the power supply is stable again (this is really important: never re-start the computer if you're having power supply instability or if the outage is caused by bad atmospheric conditions, and just wait for those to improve) and then re-start the computer as normal.

Lost count of the number of times I've has power go out and never an issue. We in the UK don't usually bother with a UPS, don't think our grid is that unreliable, not too many blackouts, brownouts or anything like that. No idea about US though. What sometimes happens fop me is that my cat treads on the off switch on my surge protector and the power goes out. 😁😼 Edited February 18, 20215 yr by martin-w

If it needs to do a chkdsk or any other issues exist, the system will do it. The NTFS is a transactional file system, so shouldn’t be any problem unless the physical HDD was fried.
