My Book Essential 500MB Master File Table corrupting

I lost all my data a few months ago. Disc was unreadagle. Easeus said master file table was corrupt. I formatted the drive and it has been working fine until  yesterday, when at stsrtup my computer went into chkdsk and said it could not repair master file table. I formatted again and unplugged the drive. This morning,  I plugged the unit back in and windows cannot find a driver for it. That’s where I am at present.

Hi there, if I were you I’d replace that drive… It has been corrupted several times.
