Can a broken/lost partition on a HDD be rebuilt and applied onto the HDD?

I know there are tools that restore partitions. I used EaseUS partition recovery, but I dont know how to apply it on to the damaged HDD so I can boot the HDD with a rebuilt partition, so far I can only browse the files that were found. Is it possible to apply a fixed partition onto the HDD?

Thanks. Altough I think I tried it a while ago and I think it didnt work out too well, so far only EaseUS is able to recover the lost partition on this HDD, I'll try TestDisk again, but would rather have something that can work directly from Windows

Hey, I used TestDisk and, but when I applied the partition and needed to restart the system, the laptop wouldnt boot because I think it was booting from the Damaged HDD. When I restarted the laptop without the Damaged HDD, and ran TestDisk again, the partition was labeled as Bootable Primary. Does it have to be just Primary and nonbootable? How do I change that? TestDisk wont allow me to do that I think.

Also, before I ran TestDisk, the damaged HDD always had assigned letter and partition was noticed by EaseUS recovery program, although the HDD still acted as if the partition is broken. After TestDisk and partition and letter dissapeared.

Bootable and primary only needs to be set for the partition you actually want to boot from and which you actually expect to boot. What do you want with damaged HDD - to boot or not to boot? If you want it to boot, it also needs to have OS installed, and you need to set the partition as "active" (that's required for booting). If not, it can be left as non-bootable. You can set the drive letters in your disk manager (control panel --> computer management --> disk manager), or the easeus partition master utility. However, note that "repaired" drives are not usually completely 100% repaired - and if only 1 bit of information is missing on them, they may fail to boot. So, a complete reinstall of windows might be required on the defective drive if you need to boot, but you cannot get it to do so with above mentioned techniques. Backup all data before that.

I dont want it to boot windows, and i actually switched to Nonbootable Primary partition as I reapplied partition on to the HDD through TestDisk. But whenever I restart my computer after using TestDisk and the damaged USB HDD initializes on startup, it sends me to post screen with a message 1234H and just stays there.
I then disabled all USB HDDs from booting (in bios) during computer reboot. And computer boots into windows and finds the damaged HDD with an assigned letter, but is still not accessible and shows up as raw in Disk Management.

I posted in another message that ONCE, yesterday, the HDD actually loaded up normally as soon as I started Recuva (recovery program), but went RAW again as I did Rescan in Disk Management.

My question is, after i reapply partition through TestDisk and restart my computer, does the damaged HDD have to be initialized before system boots into windows for the partition to be properly applied? Can I set up the partition as anything else besides Primary to increase chances of successful recovery?

And what has caused the HDD to show up normally yesterday after 2 years of being Raw and then going back to Raw again?

thx for your help herr

1) Provided that the partition was sucessfuly recovered, nothing needs to be initialized. This indicated that the partition recovery wasnt successful.

2) Whatever you set it, primary or not, wont alter your chances of its recovery, if it is already damaged on physical level (overwritten parts of crucial data)

3) This could be many things, a failing electronics on the drive changing state from functional to non-functional depending on temperature and many other factors, and it could also be due to the fact that Recuva was more successful than TestDisk.

Provided that you managed to backup all your data before, the best solution here is to format this drive and be done with it. If you need the data, go with Recuva again (in this case, do not format anything).

Recuva didnt actually do anything except forced the HDD to show up through plug&play, but not in the actual Recuva. I could never get it to show up in explorer again when trying to load Recuva.

Anyway thanks. Im going to do a deep search with TestDIsk and reapply one of the other partitions that it may find.
