    I have an external Maxtor drive which is probably been fried. Sigh. Each time it is switch on it reports that the disk is not formatted. Yes, Junk, I know.

    I will retain the power unit but need to know its rating - I would not wish to fry anything else. The label shows no rating, and the moribund hard disk also shows no rating. Can anyone identify it?

    You will have to take a better picture of the power wart, it is too blurry to read

    Sorry dustyjay, it is rather difficult to read. I'm now advised however that the DC output is 12V. Even with the actual item in hand a friend with younger eyes than I have needed a magnifying glass to read this information.

    Hi

    how much Current 'x.xA'

    To replace your power adapter:
    Your Voltage must be exact 12V
    Your Current must be equil or greater

    If your power supply is fried then how come the HDD registers at all??

    you may want to test the voltage emited by the supply before replacing it, it would also be a good idea to mesure it while it powers the drive if you can, if the voltage is steady under load is is unlikley that it is the supply.

    Hi cybersloth

    The reading is 12v 2A.

    The story is that the external hard disk was used for backup of data folders on my main hard drive, and for holding Acronis disk images. Unfortunately I made the mistake of running it all the time, rather than only when making a backup. To compound this basic error, because it used a rear located USB portal the available natural ventilation was probably not optimum. After two years of successful use it became increasingly slow to achieve disk speed when activated. This should have been an early warning. Sigh.

    Then one morning the OS reported that the disk had not been formatted. After formatting and again backing up all the folder data plus a new disk image all seemed well - until the next day, when the procedure was repeated. The disk was recognised by Windows OS but on close down lost all formatting data.

    It has now been replaced by another external hard drive at twice the storage capacity and half the purchase cost; and which does not require a power supply other than the USB port. It is only used when making a backup.

    My question was prompted by a miserly need to retain the DC supply plug for some future use, but with recognition of its input and output ratings. Any suggestion of risk and I will junk it.

    12V 2A is fairly common rating, i can see from your pic that it's got a standard type plug for the DC, I would recomend that you keep it as if it is still ok it could come in handy.

    Also you may be able to replace the actual HDD inside the faulty unit, i am a firm belliver that you can never have enough storage space.

    :)
