January 12, 20224 yr Hi, I am running a drive outside of the array using the unassigned devices plugin to record security footage. I am facing an issue where after a random amount of time, could be minutes or hours, the drive will drop out and seem to be unreachable. I have run extended smart scans on the drive and nothing comes back as wrong. Fairly new to unraid so please let me know if any other info is required. Thanks! unraid-diagnostics-20220112-1059.zip
January 12, 20224 yr Appears to be a poor connection to the drive... Reseat the cabling... Also, if this drive is permanently attached (it doesn't appear to be USB), then you're better off creating a new cache pool (Security Drive) and letting Unraid manage it instead of Unassigned Devices
January 12, 20224 yr Community Expert Looks like a power/connection problem, try replacing both cables.
January 12, 20224 yr Author Thanks @Squid and @JorgeB. I have just swapped the sata cable and power. For power I am using a splitter, 1 to 4, not sure if that could have any impact. For now I plugged that splitter into another power line coming out of the 1000W psu. Also good tip on the cache pool, I'll try that. Is there a way to narrow the problem down to power?
January 12, 20224 yr Author Update, after restarting I am instantly seeing more errors but I cannot tell from the logs which drive is the problem... I also hear about every minute what sounds like a drive spinning up. unraid-diagnostics-20220112-1133.zip
January 12, 20224 yr Author Okay thanks, so that should be unrelated. I have set up a cache pool that is currently taking in the security footage. I'll post back with updates.

January 12, 20224 yr Author Yeah good point.. The drive seems to have stabilized now. It is a 1000W psu so not sure where the problem could be. Possible it could be the drive itself?
January 12, 20224 yr Community Expert If it's a power problem it's most likely a connection/splitter issue, unlikely to be not enough power, unless the PSU is not good.
January 13, 20224 yr Author @JorgeB I am seeing issues all over the place now and having trouble sorting out what is what. How did you guys identify which drive is reporting errors in the logs? I am seeing logs with errors referencing ata4.00 for example. I see a line near the beginning of the logs like this ata4.00: ATA-10: WDC WD60EFAX-68JH4N1, WD-WX42D51800SC, 83.00A83, max UDMA/133 Does this mean "ata4.00" represents that drive with sn WD60EFAX-68JH4N1? Thanks

Thanks That's the model number, serial number is ending 00SC
