Update: Due to frequent powercuts in my area I lost some progress made and had to reindex the blockchain.
I don't have a power backup that keeps my node running continuously but I will do that later when I have that capability.
I am currently at 91% and still syncing. Will update here once the sync is completed. Thanks.
Interesting. Have you considering using a RAID configuration for your hard disk? That should at least prevent disk corruption since only one of the disks will have a corrupted write. But maybe it won't.
Bitcoin score doesn't have a good way of making data backups while the software is online.
I am sorry but I guess I have disappointed you. So long story short, this is what happened.
Ever since I made a post on this thread, I started downloading the blocks on my pi 400 with 1.5 TB HDD.
Although my internet connection was good, it took 3-5 days approximately to download the block data.
I live in an area where there are frequent power cuts (once every 2-3 days) for short durations (1-2 hours) for load balancing and I dont really have an inverter yet.
So as the blocks were getting downloaded there used to be a power cut and I would lose progress and even corrupt my HDD few times.
I tried tweaking some settings, shifted the entire setup to my laptop as well but the download was really slow.
I am not left with any option now and I guess, I wouldn't be able to download the entire blockchain.
P.S: I had tried downloading all the blocks at least 10+ times but lost it every time to the power cuts.
