D5-300C: drives not coming up after power down
Posted: 04 Jan 2020, 20:56
Good day,
I purchased a D5-300C through Amazon last month. I set it up with five identical 1TB Western Digital hard drives, two of which in RAID 1. Four volumes show up in Windows 7 once connected via USB, I format them in NTFS, start using the non-RAID ones, all good.
A few days later I go on vacation, so I power everything down (gracefully, by shutting down the OS that was mounting the drives first and the DAS next). Two weeks later I return, switch the power on, turn on both the DAS and the system it is attached to.
None of the volumes ever come up.
I try switching to another machine and multiple OSs (Mac OS X, Linux), turning on and off the DAS several times, the Reset switch... I even switch back the two volumes to SINGLE then to RAID 0 and back to RAID 1 (those two are empty anyway), pressing the Reset switch everytime. Nothing changes, except that the first couple of times all the drive lights were fixed green, now they are all constantly switched off and only the power LED is on.
The drives themselves are healthy: I removed the non-RAID ones and attached them to a desktop machine via SATA and they come up fine.
How can I diagnose the problem further?
Many Thanks
