1 of 12 HDD's disconnects & reconnects almost immediately but at random intervals on Win 10 pro x64 PC

[dominator99]

Yesterday (14/08/2024) the same single HDD in a pool of 12 HDD's was disconnected 6 times & reconnected each time within 1 minute over a period of 2 hours 20 minutes.

Today this happened 4 times over a period of 9 minutes.

Each time it was the same HDD.

Any suggestions?

See if there's any matching events in Windows Event Viewer at those times that could indicate a cause?

I have this issue in one of my systems.  In my case, reseating the SATA and/or power connector solves it for awhile.  I've not isolated to a particular component.  I also have LSA SAS cards and sometimes get an LSI controller error in the log.  No solution so far.  I've run a full Smart test on the drive which passed.  No UltraDMA errors which would point at a cable issue.  No unusual power cycle count either. I use Crystal Disk Info to monitor these stats.

The windows System event log shows things like:

- The IO operation at logical block address 0xf2824058 for Disk 12 (PDO name: \Device\00000039) was retried.
- An error was detected on device \Device\Harddisk12\DR12 during a paging operation.

- The system failed to flush data to the transaction log. Corruption may occur in VolumeId: \\?\Volume{1460a5f5-0eb5-42c7-ab63-5fba13986314}, DeviceName: \Device\HarddiskVolume14.

           Failure status: {Drive Not Ready}
The drive is not ready for use; its door may be open. Please check drive %hs and make sure that a disk is inserted and that the drive door is closed.
