Hi,

While I was working with 2 of my drives (SSD (system) and one other HD), both connected to the Intel SATA6 ports, 2 other hard drives disappeared. Some folders from one of these drives were open and suddenly closed. That's how I noticed both of these devices were missing. Coincidently, the devices that disappeared are both connected to the Marvell SATA6 ports.

I checked in the disk manager and there is no mention of my hard drive and DVD drive at all. Did I miss something, like some "feature" that would turn off or disconnect those devices from the Marvell ports? Or is this some kind of bug?

All my devices are in IDE, not AHCI.
Thanks

Does a system restart bring the drives back?

I don't know (haven't restarted the computer yet), but even if a restart brings back my drives, I wouldn't like them to disappear again while I'm recording (so while data is written on disk) as this is my audio workstation. That's why I'm trying to understand why and how it happened.

The windows error reporting in Event Viewer may provide a clue, sometimes things do hic-cup and drives disappear, normally a restart fixes issues like this, if the problem keeps resurfacing then you have reason to suspect something needs fixing.

When you can, try a system restart, if the results are the same, then we will look for a possible fix.

I restarted the computer and my devices reappeared. I'm quite sure it's somehow related to the Marvell ports as the drives that disappeared were connected to those ports. There is no mention of this in the event viewer logs.

Damn I really hate not knowing, because I can't prevent this to happen again at a more critical time, like during a recording session.

I would check the connections for slippage.

What's "slippage"? Like "badly connected" to the ports?
Sorry English is not my mother tongue and a dictionnary didn't help.

To be more specific, recheck that the card is fully seated into its slot, removing any expansion card and returning to its slot can some times correct faulty connections, which can be caused by oxidation or a loose connection.

Besides doing that, try reconnecting any data wires\ribbon wires that connect drives to expansion cards or the motherboard.


The reason for doing this is to reassure that the issue is not being caused by a faulty or loose connection.
