This HDD was working on an old NAS, but for the last couple of years, it was just turned off. Doing it now, the short test showed no errors.

I am not sure if that is included in Diagnostics, but disk log shows this : Apr 28 15:22:37 HomeServer kernel: ata4: SATA max UDMA/133 abar m2048@0xf7c3a000 port 0xf7c3a280 irq 28 Apr 28 15:22:37 HomeServer kernel: ata4: SATA link up 6.0 Gbps (SStatus 133 SControl 300) Apr 28 15:22:37 HomeServer kernel: ata4.00: ATA-9: WDC WD30EFRX-68EUZN0, 82.00A82, max UDMA/133 Apr 28 15:22:37 HomeServer kernel: ata4.00: 5860533168 sectors, multi 16: LBA48 NCQ (depth 32), AA Apr 28 15:22:37 HomeServer kernel: ata4.00: configured for UDMA/133 Apr 28 15:22:37 HomeServer kernel: sd 4:0:0:0: [sde] 5860533168 512-byte logical blocks: (3.00 TB/2.73 TiB) Apr 28 15:22:37 HomeServer kernel: sd 4:0:0:0: [sde] 4096-byte physical blocks Apr 28 15:22:37 HomeServer kernel: sd 4:0:0:0: [sde] Write Protect is off Apr 28 15:22:37 HomeServer kernel: sd 4:0:0:0: [sde] Mode Sense: 00 3a 00 00 Apr 28 15:22:37 HomeServer kernel: sd 4:0:0:0: [sde] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA Apr 28 15:22:37 HomeServer kernel: sd 4:0:0:0: [sde] Preferred minimum I/O size 4096 bytes Apr 28 15:22:37 HomeServer kernel: sde: sde1 Apr 28 15:22:37 HomeServer kernel: sd 4:0:0:0: [sde] Attached SCSI disk Apr 28 15:24:45 HomeServer emhttpd: online: WDC_WD30EFRX-68EUZN0_WD-WCC4N2HTSL2N (sde) 512 5860533168 Apr 28 15:24:46 HomeServer emhttpd: read SMART /dev/sde Apr 28 15:24:55 HomeServer unassigned.devices: Disk with ID 'WDC_WD30EFRX-68EUZN0_WD-WCC4N2HTSL2N (sde)' is not set to auto mount.

This HDD is faulty as well?

So the array was rebuilt. It took about 30 hours. But the drive is still offline, and the disk says "uninstalled". The PC BIOS sees the HDD and all the parameters. At this point, I am not sure what is happening. I assigned the device last time to Disk 3, and it asked to be rebuilt, so I did. After that, I rebooted Unraid, and it shows again that the disk is not installed. I've assigned it again, it asks to rebuild again... Doing that again, the speed again is 31 mb/s and it will be rebuilding for 27 hours... Am I doing something wrong? I am attaching the Diagnostics. homeserver-diagnostics-20250428-2134.zip

Looks like it ramped up - it's 115 mb/sec at the moment what is pretty good!

Thank you for the information. I've removed the faulty drive (and I've found out that the SATA connection was in a very bad shape - it had a crack), and replaced it with a 3TB drive. The device rebuild process is running now. Though the speed is only 16-23 mb/sec, is it supposed to be that slow? It's a WD Red 3TB drive. I believe it's slow because it's copying a lot of small files?

thank you itimpi sorry to be ignorant, I am relatively new in Unraid setups, but I am happy that it IS that simple! Thanks for the links, I will check them out. I've just seen some forum posts about replacing HDD that they had to follow some procedures - rebuilding and etc. Looks like that's not my case.

Hi Jorge, Thank you for your answer. I've re-checked all the cables - they look good. Restarted the system and now it says the device is not installed. Attaching diagnostics as well, and I cannot check the SMART also. Definitely dead, right? In case I need to change it to a bigger drive (not bigger than the parity, ofc) - is it just about replacing the drive, or it's not that simple? Thanks! homeserver-diagnostics-20250425-0958.zip

Looks like one of my hdd's is dead - it is disabled now and says it had read errors. Checking out logs of the HDD and there are several reading errors. Trying to figure out if I can safely remove it and install new bigger drive? I've attached the diagnostics archive just in case it is needed. That actually happened after updating Unraid to the latest version Thanks homeserver-diagnostics-20250423-2115.zip

Update : I've just deleted all the files from Cache and it's still full with 5GB being free.

Ho JorgeB , thanks for your reply. Where can I get full list of the files? There's also one more thing, the Cache is 500gb ssd, but I've calculated the folders in the Cache and looks like thy are taking approximately 5GB. How's that possible?

Hi everyone. Another new user, another cache problem. I've read some topics about that and even tried solutions, though nothing worked. I have some drives which are using cache and some are not. Also I have issue that my CPU is running like crazy. Not sure why to be honest - is it because cache is full ? I barely can get on to the server page. Thanks so much guys for being so patient and responsive - I've seen that in other topics. Attached diagnostics. homeserver-diagnostics-20230927-1759.zip
