I am running Windows 7 on an Acer Aspire M7720 with three internal SATA drives; drive #2 and #3 are on a removable HDD rack. Drive #3 (on the second removable HDD rack) shows up as removable device in the system tray. If I take drive #3 and put it in the first rack, it shows up as an internal drive. If I put any other drive in the second removable rack, that drive is also shown as removable device. I would like to fix that so that the drive in the second removable rack also is listed as internal drive. Since this seems to be independent of the actual drive in the rack, I checked the BIOS, but that third SATA port uses the same configuration as the second rack. So far, I could not find a solution for this problem (it's really more an annoyance than a problem), any ideas are welcome.
