Tomato v1.28.8752 ND USB vpn3.6 USB connected NAS sleeps

    Running teddy_bear Tomato Firmware v1.28.8752 ND USB vpn3.6 on Linksys WRTSL54GS.

    Since this router has a USB port, I have connected a Seagate Free Agent (ST305004FDA1E1-RK) USB enclosure containing a 2 TB harddisk to it to practically use it as a NAS. The harddisk, NTFS formatted, is correctly detected and shown in the USB & NAS section of the tomato firmware. It is shared and mapped as a local drive letter on the desktop PC running Windows 7 Ultimate 32-bit.

    This NAS harddisk setup is primary serving as a central download and storage location for my home media, and is connected to the (NMT)network media tank on the same network to play movies/songs/photos.

    Here comes a practical trouble, my router and the attached USB Drive is running usually 24/7 , since I am not at home in the day time, it remain idle for a while. And as usual the attached USB Harrdisk goes to a sleep or spin down state.Any other usual USB2.0 external harddisk connected directly to the computer becomes awake when it is accessed and takes a while on the first access to show its file and folders.

    Now whenever in the evening I try to access the harddisk via the NMT menu, by going to the mapped shares (samba shares created in tomato), the NMT searches and then fails after a while, because the spinned-down harddisk , never becomes alive or spins up when accessed. Basically it never wakes up

    To remedy the problem I have to keep rebooting the router so it can refresh and reinitialize the attached external USB harddisk, which obviously is not the best solution.

    I did some research and this is a common problem with some remedy provided by a command called sdparm. Check this link out http://alienghic.livejournal.com/382903.html. But apparently in the tomato kernel the command sdparm is not present.

    So any idea how to install this utility, maybe a BusyBox compilation or any other possible way to address this situation to prevent the USB attached harddisk from spinning down.

    Teddy Bear........help....

    Thanks for reading.
