For your dealership with 11 employees, replacing the shared USB drive with a more secure and reliable solution is important. A small Synology NAS, such as the DS220j or DS223j, fits within your $500 budget and offers centralized local storage, RAID-based redundancy, and the ability to back up to Google Drive using Synology’s Cloud Sync or Active Backup for Google Workspace. This setup ensures data protection, remote access, and team collaboration. Using Google Drive directly is another option, providing cloud access and easy collaboration without extra hardware, but it relies on internet connectivity and offers less control over backups. Overall, a Synology NAS with Google Drive backup provides a practical balance of security, reliability, and scalability for your business.
For your HP 800 G4 Mini, the two NVMe drives can be set up in a RAID 1 for Docker applications with MySQL. The simplest and most reliable option is mdadm with Ext4, which gives stable RAID 1 redundancy, predictable database performance, and easy monitoring with LibreNMS. A ZFS mirror is also an option if you want checksums and snapshots, but it requires tuning for database performance and uses more memory. BTRFS RAID 1 is less suitable for write-heavy databases due to potential fragmentation and slower writes. Using two identical NVMe drives is recommended for consistent performance. Drive failure alerts can be handled through mdadm or ZFS and integrated with LibreNMS. Overall, mdadm + Ext4 is the straightforward choice, while ZFS adds extra protection with more complexity.
You can set up a RAID with NVMe drives in slots 3 and 4 on the MAG Z790 Tomahawk MAX WiFi motherboard without affecting your Windows 11 installation on slot 1, as long as the OS drive is not included in the RAID.
The motherboard supports Intel RST (Rapid Storage Technology) RAID for NVMe drives. You can create the RAID array through the BIOS or using the Intel RST utility in Windows. Check the motherboard manual for lane sharing, since some NVMe slots share PCIe lanes with SATA ports, which could disable certain ports if not configured correctly.
With two NVMe drives, you can choose:
RAID 0 (striping): Faster performance, no redundancy. If one drive fails, all data is lost.
RAID 1 (mirroring): Data is duplicated on both drives. One drive can fail without losing data.
SATA drives can also be configured in RAID using Intel RST. The same options apply depending on the number of drives.
Because your OS drive is separate, creating a RAID on slots 3 and 4 will not affect Windows 11.
Thanks everyone. Gonna give the full firmware flash a try tonight. Hoping it boots at least once so I can recover my stuff. Appreciate all the tips
Just adding this..don’t keep it on that error screen for too long, it can cause AMOLED burn-in. Try forcing a reboot every few minutes while you prep your files for flashing.
Smart move. There’s PC-based Android data recovery software that works once the phone gets detected again — it can scan internal storage and help you save photos, videos, etc. before you mess with system files again.
Got it, I’ll try that battery trick. If I manage to bring it back, I’ll use recovery software to pull my data before I flash anything else again.
I’ve had this exact thing happen on an A7 after a failed TWRP flash. What worked for me: disconnect battery for 5 minutes (if you can open the phone safely), reconnect, then immediately boot to download mode and re-flash full firmware.
If you’ve already soft-bricked it and the PC still recognizes it under Odin mode, that’s a good sign. You can still get data back later. But if the flash fails completely and it doesn’t get detected, you’ll need to look into data recovery software that can scan bricked phones once they’re at least partially functional again.
Yeah, don’t flash just the recovery next time. Re-flash BL + AP + CP + CSC (not HOME_CSC though, that one wipes). If you’re lucky, it’ll boot back normally and your data should still be intact.
If it’s looping back to that error screen, it’s probably a corrupted bootloader or recovery partition. You’ll need to re-flash the full stock firmware through Odin again — not just TWRP.
You can get the official firmware from SamMobile or Frija Tool, depending on your region. Just make sure you match your phone’s model number exactly.
Tried that combo, but it just goes back to the same screen again after reboot. I can’t reach recovery or download mode.
Classic Odin soft brick situation. You basically interrupted the firmware flash or used a mismatched TWRP image. The phone isn’t dead though..it’s just in a fail safe state.
Try holding Power + Volume Down for around 10 seconds; it should force a restart. Then immediately go into Download Mode (Power + Vol Down + Bixby).
Hey everyone,
So I was trying to install TWRP on my Samsung Galaxy A15 using Odin. Everything seemed fine at first, but after flashing, my phone rebooted and got stuck on this weird screen that says:
“An error has occurred while updating the software.”
It’s been like that for hours now — it won’t power off, won’t go into recovery, and I’m scared it’s gonna get screen burn if it stays like this much longer. Holding Power + Volume Down + Bixby isn’t helping either.
Any idea how to fix this? And more importantly, is there any way to save my data? I had tons of photos and notes that weren’t backed up 😩
The ZFS mirror pool became degraded after one drive failed, and the second drive showed errors during resilvering, likely due to heavy I/O on large drives. Keeping both drives active and using the system during recovery slowed resilvering and may have caused further issues. The system is now unstable and only boots in a degraded state. The best course of action is to stop all non-essential activity, run SMART tests on the remaining drive, back up important data immediately, and avoid writing to the pool. Once a replacement drive is ready, replace the failed drive and let resilvering finish without additional load. Temporarily removing L2ARC or SLOG devices can reduce stress during recovery. The priority is to stabilize the pool and secure the data before proceeding.
