Hi All,
I have a home-built PC running W7 pro with a Sata drive as the primary drive, and a second PATA drive for general file storage. This has been running fine for a couple of years. I have recently installed a hot swap sata drive bay into the pc, so I can plug my new SSD drive in and make backups. When I click into the system tray / notification area to 'safely eject device' I select the SSD drive, but the system 'ejects' both the SSD drive and the PATA drive. The PATA drive no longer shows up in 'My Computer' and no longer shows up in Computer Management / Storage. I have to reboot the PC to get the PATA drive to show again.

Firstly - how do I only eject the SSD drive?
Secondly - do I need to 'safely eject' if I know my backup to the SSD has finished - can I just take it out?

Many thanks,
toomutch

Brief expert note: the symptom describes — using "Safely Remove" on the hot‑swap SSD and having the internal PATA drive disappear until a reboot — points to a controller/representation problem rather than a fault in the PATA disk itself. As suggested, the way the front bay is presented to Windows (per‑slot host ports vs. a single bridge/expander) changes how "eject" is interpreted, and a removal action can end up stopping a shared host or driver.

Recommended troubleshooting steps:

  • Confirm how the bay is wired and enumerated: check which motherboard/controller ports the bay cables use and note the device names shown in "Safely Remove Hardware".
  • Observe Device Manager and Disk Management immediately before and after an eject: note which disk entries disappear and which storage controller or driver shows activity. Use "Scan for hardware changes" to see if the device returns without reboot.
  • Check Windows Event Viewer (Windows Logs -> System) for disk or driver events at the time of the eject; the source name will often indicate which controller was stopped.
  • Verify BIOS/UEFI SATA settings: hot‑plug must be enabled on the specific port and the controller should be in AHCI mode for reliable hot‑swap. Changing SATA mode on an installed OS needs care.
  • Update chipset/SATA drivers and, if possible, test the bay on a different SATA port or a separate controller card to see whether the behavior follows the bay or the host.

About "do I need to safely eject?": yes — always ensure backups are finished and the volume is idle before removal to avoid corruption. If the current eject action also disables other drives, use safer alternatives until the root cause is fixed: set the drive policy to "Quick removal" to minimize caching, stop backup software and close file handles, or shut down the PC before removing the disk. Summary: isolate whether the bay is presenting a single shared host or independent ports; fixing that (BIOS/driver or re‑wiring) will allow single‑drive ejects without affecting the PATA device.

Does the drive tray use a single sata connection or does it have a sata lead per drive slot?

IF it's a single lead, there would be some on board logic to show multiple drives through the simgle conenction, but it would still be 1 device you are ejecting, affecting all other connected devices.

The cages with multiple leads conenct 1 drive to 1 port with no onboard logic to speak of.

The drive bay can take up to 2 sata drives, and has two power leads and two sata header leads (and an e-sata lead). But the problem is that when I click on 'eject sata drive' it also loses the internal PATA drive
