To use the Apacer HandyDrive USB disk on 1.5.2, add this entry to the 
quirks table in /sys/dev/scsipi/scsiconf.c:

        {{T_DIRECT, T_REMOV,
         "Apacer", "HandyDrive",          "1.06"}, SDEV_NOMODESENSE
              | ADEV_NODOORLOCK | SDEV_ONLYBIG | PQUIRK_NOBIGMODESENSE},

It appears not to be needed on 1.6, but I won't be able to try that 
until tomorrow.
