Access to hdd

Hi i recently got my xbox modded and i was wonderin, in any1 could help me access the hdd,

when i switch on my xbox i hav to keep hold of the power button for upto 5 secs to power it up, and i am unable to access the saved files on the music files i hav stored on my xbox hdd. Previously to getting it modded

when i press the button and release it it just makes noises as if its goin to power up but then cuts off.

i can save and load games but cant access it to delete saved games which i no longer play or music, i have the evox mod if that helps.

ive contacted the shop who modded it they say there's nothin worng with it and since then they hav moved locations to elsewhere!

any help would be appreciated

thank you in advance

It sounds to me that they've modded it for you but haven't put the nessecary programs on there, like xbox media center. Have a look over on http://www.xbox-scene.com/ . They will be able to help you more
