Did you, in device manager, mark the sata drives to optimize for removal
instead of performance? (Just a thought?)

From my archive:

This can be achieved by modifying a registry value.

Devices are shown there if they are marked as removable and
if they do no have the 'surprise removal ok' flag. These are
bit coded flags:

From cfgmgr32.h:
#define CM_DEVCAP_REMOVABLE (0x00000004)
#define CM_DEVCAP_SURPRISEREMOVALOK (0x00000080)

The device capabilities are found in the registry in a value
named 'Capabilities' under (sample for one of my IDE drives):
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCIIDE\IDECHANNEL\4&2527311&0&0

If you take away 4 from the value or add 80h and then
refresh the save removal dialog by toggeling the checkbox,
then the drive is gone.
But the value is reset when you attach the drive for the
next time or on next boot. This is hard coded into the driver
and read each time the drive is loaded. If you export the modified
value a reg file then you can silently load it on startup by
regedit /s hidecardreader.reg

The device id string of your drive (this
PCIIDE\IDECHANNEL\4&2527311&0&0 thing) is found in the properties
of the drive in the device manager. My ListUsbDrives tool
shows it too (the 'Ctrl DevID'):

Meanwhile I've added a function to do this to my USB
drive letter manager.

Still, you have to determine the device id, but everything
else is left to the USBDLM service.

In the USBDLM.INI set for instance for an USB drive

[HideFromSafelyRemoveHardware]
DeviceID1=USB\VID_058F&PID_6369

But you can use the drive's 'Friendly Name' too, like

[HideFromSafelyRemoveHardware]
DeviceID1=Multi Card Reader

Thanks for your response, which I will further investigate.

I really wouldn't worry about it.

I think you will find if you try to "safely remove" your main HDD, XP will
not let you, saying it is in use, or something similar.

If you are so concerned try the reghack. It seems pretty simple, just do a
system restore point first.

You could probably use the same trick for your other devices, you would just
need to know what registry key to add the DWORD value to.

If you accidentally remove something else, you could try going into device
manager and "scan for hardware changes", and the device will probably
re-connect without a reboot.

Thanks Jeff,

Already spotted that one, and checked a while ago, - hd is set for
"perofrmance."
I have spotted a couple of possibilities, one is that it's to do with having
an Nvidia Nforce chipset on the board, (of the machine in question i.e. not
my main PC). Having said that, I could have sworn that I tweaked my
registry ages ago, when I fitted two SATA hd's to my main PC, to solve the
same issue. I've rummaged through my *.mht directory and can't find it,
....I try always to save such details for future reference.

....haven't tried this yet.

regards, Richard
