    Hi there

    NAS200 unit with Samsung F3 1TB hard drive installed yesterday
    Error message: Error 0x8007045D I/O device error
    Firmware: V3.4R79

    I'm a new to the Nas200. I installed the hard drive yesterday and formatted it as Journaled (not RAID). Copying files over yesterday worked fine. Today, however I am randomly receiving the error code stated above. Some files are moved & copied over without any problems, but others continually display this error code. The problem is quite random. Most of what I am copying over are video & audio files. I had purchased this unit to stream movies and music to devices around the house (xbox 360, laptops, mobile phones etc).

    Also, and on a separate issue, the drive is very hot. Is is safe (for the data)?

    Can anyone help?

    The fact that the drive is hot probably IS the issue.

    Hard disks are mechanical devices and generate heat, while at the same time they are precision devices that need to work within a certain range of temperatures. If they get too hot internal parts start expanding too much and you will get intermittent failures like the Device I/O error that Windows reports, or it will completely stop responding. The only thing to do is to let the drive cool down until it's within its operating temperature again.

    Unfortunately the NAS200 is notorious for its inadequate cooling. I had a Seagate hard disk in my NAS that got so hot that it stopped responding completely. After I put it in the freezer for a half hour or so (not recommended because of the humidity!) it worked again. I used a Dremel to drill out the holes on the sides of the NAS and cut out the insides to make space for a 60mm fan (SilenX brand, available at Newegg and Fry's, they are VERY quiet!) but the Seagate still got too hot. I now have a 1TB Western Digital Caviar Green in the NAS which still gets warm but not so hot that it stops working. Drives that run at lower RPMs don't get as hot, generate less noise and you won't notice the difference in speed in the NAS200 anyway because the NAS hardware is the bottleneck.

    I recommend replacing the drive with a "green" type.

    And no, your data is NOT safe if the drive gets that hot.
