Hi all.

I have had no problem with my external hard drive, but recently its not beeing recognized and needs formating :



When i right click on it, a window opens and says it should be formatted. but i have data on it and can t. when i cancel the window, this messeage come :



it is not also recognized in kaspersky or tune up, so that i could scan it for viruses or perform a check disc with them.

It is not recognized also in my computer with the name that i had given to it and just as a local disc appeares.

I have tried on two systems with both 7 and xp os , but still no go.



Thanks for the Help.

Problem solved by performing a check disc, using the program ease us partition master

Thanks !

Good to know that checkdisk fixed it for you.

While I do not want to create a scare, a CRC error in a hard disk is not a good sign. The hard disk may be degenerating creating bad sectors which in turn may make it RAW. Whether more and more bad sectors will be created or it is just a one-time aberration is very hard to predict.

Keep checking the hard drive periodically with the manufacturer's diagnostic utility.

As a matter of abundant caution, you may consider moving all critical data to another new external hard drive and use this drive only for non-critical data.
