I have a Seagate ST300003U2 external hard disk that no longer seems to power up. When I plug the cable in and switch on the power, all that happens is the green LED power light flashes. Any suggestions? Many thanks Jason

SOURCE: Seagate FreeAgent External 500GB HDD - Data Recovery

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. 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. so it might be a possibility that when u connected ur hdd,the power ON/OFF switch was awredy ON IF hdd has one. 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 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. it would still be there. HOWEVER,its recommended that u dont try these things personaaly if u are'nt too tech savy. u shud consult a tech or a freind who knows abt this.

SOURCE: Flashing green power light

Spoke to maxtor. The blinking green light on the power cord is a problem with the external casing for the hard drive. Several of the posts talked about taking the case apart and connecting it to the pc to download information. I thought they were crackpots. After talking to the service tech on the website it looks like that is the only fix. So... based on all the posts with the same issue I may avoid this product line int he future. Hopefully it is truely a backup for you in which case toss the old one and buy a new ext. HD. If it isn't a backup take it apart gingerly, download the information, replace the hardrive.

Hi,

Sounds like you have either bad voltage from your power adapter or a failed enclosure.

First thing to do is check the ac adapter your using, find the output Voltage, should be between 5-16V and the output Amperage, should be between .25A and 5A depending on the type of seagate enclosure you have.

Now look at the stickers on the outside of the drive enclosure to verify that it uses the same voltage and amperage. If it doesn't you're using the wrong adapter(easy mistake after a move). If it's the correct adapter then you may have had a failure in the enclosure.

The next thing to try is to take the drive to your local PC shop and ask the technicians there to transfer the hard drive inside it into a new enclosure for testing. If this works buy the new enclosure and you're on the way. If this also fails, something has failed in the drive itself and you will need the help of a pro. Have the technicians either return it to the original enclosure or pack it in a static free bag.

Now you have a couple options. I can refer you into one of several professional facilities depending on your needs. The most common one I use is www.armor-it.com They are the least expensive on average but average 4-5 weeks for non rush orders. If you need a faster turnaround and don't mind spending a few extra bucks, reply back and including your Country, City and State and I will refer you into an appropriate facility near you.

Seagate raw drive


Your data is already gone. The drive is raw. No partition no format.
here is a link to a free data recovery program, this probably wont work but may be worth a try

ST300003U2 hard drive powers up ok, power light on, message on pc "usb device not recognised " .one of the usb devices has malfunctioned and windows does not recognise it.


Try to plug it in to another PC to see if you get the same message. See if you can run a scan disk on it from Windows to see if it's bad or going bad too.

To be honest, device not recognised is a bad sign. :(

Verify what Drives have been detected by your Operating System by using Windows: Control Panel -> Admistrative Tools -> Computer Management -> Disk Management -> Your Hard disk(s) will be displayed with all existing partitions and any assigned drive letters.
Your external (or internal) drive must be recognized as having formatted partitions that have a drive letter assigned to each required partition.
Hope it helps: let me know how you go!

I wanted to know whether ASUS A7S266-VM/U2 will support seagate 7200.10


M/Boards support all makes of hard drive
Are you sure you connected it correctly
The wide ribbon cable that goes in the rear of hard drive should
1) Be connected to M/board in the No 1 connector with the stripe on cable to the No 1 pin
2) the stripe on cable should go next to the 4 pin power plug on hard drive
Also ensure your BIOS is set to Auto detect of driives
