seagate barracuda 7200.10 320gb sata hard drive

SOURCE: Seagate Barracuda 7200.12 show 0MB issue u shud consult a tech or a freind who knows abt this. HOWEVER,its recommended that u dont try these things personaaly if u are'nt too tech savy. so in dat case i would suggest that u go through the manual of ur external hdd to see how to access the the casing in which the hdd is there.then if u happen to get thorugh n it turns on then u dont have to recover ur data. so wat i feel is dat u can try opening the hdd and then connect the hdd to ur desktop with help of the BUS CABLE used to connect the HDDs in desktops. so it might be a possibility that when u connected ur hdd,the power ON/OFF switch was awredy ON IF hdd has one. the difference in plug doesnt make a difference cuz u can use the same plug,the voltage is same thorugh out in ur place from the substation. Well firstly if u wana recover ur data u have to make the external hdd power up but thats the major area of issue that its not powering up.
