gotcha. that’s crazy odd. I did just get a bad unit; ssd’s failed overnight after a sync. Here’s something to try: Here’s the simplified process to check your NVMe SSD’s health on Umbrel’s Debian-based OS: 1. **SSH into Umbrel** : `ssh umbrel@umbrel.local` 1. **Install smartmontools** : `sudo apt update sudo apt install smartmontools` 1. **Confirm NVMe Device** : `lsblk` Look for /dev/nvme0n1 (Umbrel Home’s 2TB NVMe SSD, likely mounted under /home/umbrel). 4. **Check NVMe SSD Health** : `sudo smartctl -a /dev/nvme0n1` Key metrics: - Percentage Used: \<10% is good, \>50% indicates wear. - Media and Data Integrity Errors: 0 is ideal. - Temperature: \<65°C. - Overall Health: PASSED. 1. **Optional Self-Test** : `sudo smartctl -t short /dev/nvme0n1` Check results after ~2 minutes: `sudo smartctl -l selftest /dev/nvme0n1` ---

interesting… i found some info about possible interference from electrum. If the disk is fine, you’re not using electrs, it maybe time to start over. **Check for Electrs Interference** The Electrum server (electrs) can cause sync issues. If installed: - Uninstall electrs via the Umbrel App Store. - Restart the Bitcoin app: `~/umbrel/scripts/app restart bitcoin` - Reinstall electrs after the node syncs to 100%. **Clear Corrupted Data and Reindex** If reindexing fails or loops: - Stop Umbrel services: `sudo systemctl stop umbrel-startup` - Delete corrupted blockchain data (preserves wallet): `sudo rm -rf ~/umbrel/app-data/bitcoin/data/bitcoin/blocks sudo rm -rf ~/umbrel/app-data/bitcoin/data/bitcoin/chainstate` - Restart Umbrel: `sudo systemctl start umbrel-startup` - Reindex again (this forces a fresh blockchain download, which may take days). ---

Hi! I’m having the same issue. I have a brand new Umbrel Home that arrived just 3 days ago, and it has never been able to finish syncing the blockchain. I’ve already tried at least 10 times, encountering different types of errors at various block heights. I also tried reindexing, and even deleted everything to start from scratch, but I always end up getting errors like: - **Fatal LevelDB error: Corruption: block checksum mismatch** - **ProcessNewBlock: ActivateBestChain failed (bad-txnmrklroot, hashMerkleRoot mismatch)** I ran disk and RAM checks using `smartctl` and `memtester`, and everything seemed fine. At this point, the only thing I can think of is a potential hardware issue from the factory. @scanz were you able to solve the issue? Thanks in advance! ---

Thanks for the response. I’ll try to do the same, since I haven’t received any replies on the forum or from technical support either. Unfortunately, it’s turning into an expensive paperweight.
