What may be the issue with external hard drive on USB?

By sayef ·
I have a 160GB Western Digital USB external hard drive. Some times it 'behaves' quite normally, but at most of the times, it disconnects itself from the port very frequently, and many times it also gives the message for formatting the drive! Sometimes, the computer also fails to recognize the existence of the drive. After taking out and putting in the USB cable 2/3 times, the drive becomes active. And once active, 99% percent of time the working becomes quite smooth.

What is the problem, and how can this be overcomed? Is there any USB version problem? Is there any chance of physically damaging the drive, and thus loosing my important data? Please answer at the earliest.

Yes, there is a VERY good chance of data loss

Yes, there is a VERY good chance of data loss, in fact, I'd place money on it failing. Back up that drive posthaste!!!

Sounds like something is failing in the circuitry of the drive or the USB case electronics. If under warranty, send it back for repair (wipe it first with a tool like DBAN)

take a look at the power supply

by databaseben In reply to What may be the issue wit ...

be sure that the drive has an external power supply. although, power is provided through the usb ports, sometimes it is not a reliable source to energize power hungry devices.

in any case, what i'm trying to explain is that if the external drive looses power, then it can be seen by the o.s. as disable, dysfunctional or not connected.

incidentally, you didnt' mention what o.s. your using. however, microsoft came out with a patch for xp that addresses the instability in usb power supply.
