input with options: Title: Bad Quality Control Review: Do not buy this drive.Our company bought about 12 of these, as an economical large-storage and backup solution. 3 have already failed within 2 months, and I am having to think up other backup solutions in anticipation of the next one. The failure mode is very similar to what some of the other reviews have said on this site and others (try PCWorld too) - the platter starts making some racket and the thing just quits. Maxtor is a reputable enough company to honor their warranties, but it's not worth the hassle and potential data loss. Is this product review negative?
output: Yes

The xsb726 filter does not fit this unit. I tried to contact shark and ended up in India where I could not get a straight answer. Love the unit, but unless you want to buy it and throw it away when the filter plugs up, try something else. Is this product review negative?
