I'm trying to better understand/diagnose significant number of Spin Retry Count entries in the Log for all 4 drives in this enclosure:
Mediasonic HFR2-SU3S2 PRORAID external enclosure
Currently via on-board Asmedia 106x SATA Controller (AHCI) [VEN: 1B21, DEV: 0612] Version: 220.127.116.11, 6-24-2020
(previously mostly connected via SYBA / IOCrest SD-SA2PEX-2E PCIe SATA card with Marvell controller )
4 x Hitachi Deskstar 3TB drives model HDS723030ALA640
In RAID5 configuration
- Enclosure and drives purchased and put into service in July 2011.
- Configured for RAID5 from the start, and never changed.
- The enclosure has been pretty rock solid and reliable for 11 years, used until recently with Windows 7 (now Windows 10.)
- HD Sentinel first installed July 2020
Prior to purchasing and using Hard Disk Sentinel, I did not know much about the health or status of the hard drives. Initially, I mostly used HD Sentinel to monitor drive temperatures (which led me to add additional external fan for cooling.) But over time, I've noticed the HDS Log indicating a fair number of Spin Retry entries for all four drives, beginning shortly after I installed the software. The enclosure has been attached much, but not 100% of the time the computer is used.
Since the spin retry issue is logged for all drives, I'm guessing it's more likely due to power supply issue, but also wondering whether perhaps this particular enclosure's "normal operation" might function in a way that reports a problem in HD Sentinel that might not actually be a problem? I Could Not Find much specific to this enclosure and this particular issue here in the forum or online in general, so I'm hoping to get some feedback.
I will use the "send test report to developer" option as well.
