Anyone Ever Used the Hp Compaq Presario CQ42 Notbeook Here?

I do data recovery. When the disk shows SMART errors this is caused from bad sectors on the disk. Each time the head tried to read a sector that is bad it will mart it unreadable and try to reallocate this data to a good sector on the disk. The more bad sectors your disk has the more reallocated sectors you get on your disk. Each error is reported to the disk SMART. With too many SMART errors your disk has problems with seek and reading sectors. The only way to correct his problem is to back up your disk and install a new disk. There are special tools for data recovery that an expert can use to try and find all the bad sectors on the disk and reallocate them. This does cut down the disk space. However on disks like this the platters are degrading and this causes even more errors. Soon it is even possible the heads can stop reading the platters on the disk. There basically isn't any other solution in your case but to change out the drive.

Have you run a disk analysis on it? That will tell you if there are any integrity problems with your hard drive. From the sound of it, though, it's very possible that your drive is failing and it's only a matter of time before it crashes. Look into purchasing a solid state drive (SSD) instead of a traditional hard drive, since they're more durable and tend to last a bit longer.
