Question about PC Desktops

1 Answer

I have a Seagate 400GB External Drive (ST3400601CB-RK) for which I have lost the power cord. I have found a cord but am not sure if it is the correct one... what is the volt/ampere required for this drive?

    Thanks for the response!  However, what I am really looking for (though my question did not make this clear) is the DC voltage/current rating after the ac/dc converter going into the case itself.  The power cord I have outputs 12V DC 5A.  I would hate to plug this in and fry my drive if it is expecting something like 5V DC.  So, I am hesitant to just plug it in to see if it works.  There is no power input specified on the nameplate on the back of the case to tell me if the power cord I have is the correct one.

POWER- AC 90V ~ 264V, 47 ~ 63 Hz make sure the power cord specs match.

    Hi Lowdead,

    Unfortunately I was unable to locate a proper replacement cord spec sheet. The only other solution I can offer is, if you have the drive serial #, Seagate can give you the proper specs, without it I could get nada, sorry. 5 A may be to high according to seagate, however without a serial I cannot give you a solid answer.

Backup failed.Caused by Lost connection to drive

If you are sure that the USB cable is plugged in correctly, the cable is probably broken. Try replacing the USB cable with another or a new one.

I only want to backup new information but the drive is backing up the entire hard drive each time. How do I change this?

Set your backup program to only backup the folders you need. You have it set to backup the drive. If your set up is to backup only "New" info, then the program needs to scan the drive to find out what is new.

Freecom 400GB Hard drive not recognized.its a Freecom mobile drive xxs 400gb , my pc just cant recgnize the hard drive

I'll assume your using Windows.
I'll assume it's a USB drive.
I'll assume it is an external drive.
And I'll assume it's formatted as NTFS.

Try using the USB (or FireWire) port for anouther drive to see if that is the problem, if it is then reinstall the driver for the port, through the Computer Managment Concole (assuming yur using windows).

If you formatted the drive as FAT, re-format it as NTFS.

When i connect my seagate via usb nothing comes up on my pc, the light comes on on the external h/d but nothing pops up on the pc? help please i need precious photos on it. thanks

have you try connect your pen drive to the same usb port, is it working?
If Pendrive is working but not the Seagate hardisk. Most propably is your USB power is not enough to support the External Seagate hard disk, you need to supply more power to the Seagate hard disk by using USB Y cable(1 end connect to Seagate hardisk where the other end got 2 USB connector to connect to your PC).

I have a Segagate USB external storage drive. It went out of warranty about 4 mos ago . When I first noticed a problem, the unit was making harsh "clicking" sounds ( about 2/sec).... now when I...

The clicking sound on the hard drive normally means that the hard drive is on it's way out, but can also be in some cases the power supply. The best way to test this is check the voltage of the power supply with a multi meter. If the voltage is good, then remove the hard drive from the casing and plug it into the PC, depending on the connection IDE or SATA you might need a connector and see if it works normally.

But my guess is that the hard drive is crashing....

Do you know where i can buy a circuit board for my seagate external hard drive 500gb pro? pn: ST305004FPA1E2-RK firmware 3.afk. Thanks. Jason

You can try Ebay, as I have found several that I needed in the past on there, with good results.

Just search for "seagate logic board", and browse through them.

Be sure it's the EXACT model number, as most vendors don't accept returns on them. If you don't see your exact model, some vendor may have them, but don't have them listed.

Good luck.
