Here i have an external usb disk. And i have found two issues, utilizing it under Haiku. Are both related to power on. The first: this external hdd has a power switch. in Haiku, when I turn on this hdd, it doesn't appear in the list of mountables drives. To do this i have to unplug the usb cable, turn on the hdd and reattach the cable: in this way the hdd will be available. This problem doesn't occurs under Windows 7 and under Linux.
The second issue is always related to power management: this hdd provide the spindown feature (after about 15 minutes of inactivity, the hdd automatically power off itself, and when i access again to disk, the hdd turn on again automatically) So, under all other operating system this operation between power off and power on happens instantly, but under Haiku takes some seconds of delay (eg when i open the Tracker inside this hard disk).
I have also noticed that when i write data to this hdd, Tracker takes more CPU.
hrev 45349 and i have noticed this on every Haiku revision.
PS: I have added this Ticket under "Tracker" category just because under Servers category ain't available "mount_server".
