Hey everyone, I'm really new to this, trying to set up BitcoinCore for the first time and I'm hitting a wall with an error during the sync process. I’ve got a brand new 1TB external SSD. Did some quick searches online and it seems like the block data might be corrupted, possibly due to the hardware. I figured the new SSD could be the issue, so I swapped it for another fresh 1TB external SSD, but I'm still getting the same error at around the same block. Totally lost on what to do next. Any advice would be super helpful. Running: bitcoin-25-arm64-apple-darwin.dmg OS: MacOS Sonoma 14 Specs: Apple M2, 16 GB Ram, 256GB HD, 1TB external SanDisk SSD (for BitcoinCore) Problem Description: When syncing, I get this message: "Error: A fatal error occurred, see debug.log for details", and then BitcoinCore crashes. Every time I try to restart, I see the same error. Here’s a screenshot of what’s happening: https://imgur.com/a/XHID1TQ And here are my log files: https://pastebin.com/NgghHzmW 2023-10-13T20:49:06Z UpdateTip: new best=00000000000000e527fc19df0992d58c12b98ef5a17544696bbba67812ef0e64 height=181440 version=0x00000001 log2_work=68.176392 tx=3425659 date='2012-05-24T18:10:29Z' progress=0.003885 cache=252.4MiB(1830338txo) 2023-10-13T20:49:06Z UpdateTip: new best=00000000000008b5dcfd70f61ab44bcb92e257c976ce0aeb820105b292477a65 height=181441 version=0x00000001 log2_work=68.176421 tx=3425976 date='2012-05-24T18:25:07Z' progress=0.003886 cache=252.4MiB(1830046txo) 2023-10-13T20:49:06Z ERROR: ReadBlockFromDisk: Errors in block header at FlatFilePos(nFile=11, nPos=

Thanks.  Yes that seems to be the solution here. To recap for any others in the same scenario - This is generally a Apple Mac OS-only problem. My external SSD was in ExFAT, and I'm on MacOS 14 Sonoma.  I used Disk Utility to reformat to APFS and restarted the sync.  No more stalls or errors.   I'm back on the way.  Thanks.

Some advice do not use sandisk. use samsung or crucial sandisk and western digital have had a lot of fails. In many different systems. I will look for the reviews. https://www.tomshardware.com/news/wd-faces-class-action-lawsuit-over-sandisk-extreme-pro-ssd-failures I suggest these instead. https://www.amazon.com/SAMSUNG-Portable-Photographers-MU-PE1T0S-AM/dp/B09VLK9W3S/ref=sr_1_3? once you do your external having a second copy on a samsung is worth having.
