External Harddrive requires formatting, but can't complete the formatting, how can i get it back to work?

By kchimwanda ·
Hi TechRepublicans!

I have a SATA internal harddrive which i have converted into an external by covering it in an external casing. Now it's performing bad, when i connect it to my laptop, its pops countless "Format Disk" messages. These messages come atleast five or more minutes after i connect it, something that started recently. But the first days i converted it, it was working just fine. I have failed to format this drive.

How can solve get it back to work?

if it still chokes then it was damaged either by static or by the enclosure

also not all internal drives play well as externals especially in cheap USB enclosures that don't provide enough power

if it works internally then the enclosure is not providing enough power

You could also test the HDD with it's makers Testing Utility

And see if it's suffered any damage and that it is adversely affecting the drive.


Though with external Cases unless you have a dedicated Power Supply of some sort for them the Power Issue is always a very big one with HDD's in external cases. Even if it's only a small drive 1 USB Port particularly on a Modern NB is unlikely to be able to provide enough current at the 5 V DC that is available from the USB Port.

If you have a Y Cable for this enclosure you need to make sure that both of the USB Plugs are in different USB Sockets on the NB not plugged into a Umpowered USB Hub.

Back in the old days of IDE Enclosures they used to recommend that no drive bigger than 80 GIG was fitted as there wouldn't be sufficient power available to reliably run the drive. While not as important now it still should be considered by looking at the Power Requirement of the Drive and then comparing that to the Power Available from the USB Sockets. Remember that the USB Standard is 500 Milliamperes but modern NB cut this down to extend battery life.
