1TB slowly slipping away

by milo.kecic / July 9, 2009 2:59 PM PDT

I have 1TB Buffalo DriveStation HD-CEU2, which i bought last year. It has been running perfectly up till about a week ago. Where just randomly 40-50% of my files on it don't work sometimes. Like my movies folder for instance, Some movies will play fine, and some will play for a few mins before crashing and some wont play at all. Same for my Music folder. And its absolutely random as to what plays and doesn't. There's no pattern. Its got a lot of important stuff on their which is backed up. But i really don't under stand why i cant watch movies or listen to music from it. Dose this sound like a virus on it? I really don't wana lose all my music which i have been collecting for a long time now.

It wont even let me copy the music or movies of it to another harddrive, the copy progress gets nearly to the end when an error pops up informing me of file disk error.

Also nothing changed on my computer when it started breaking. Iv just today restored my computer to its factory state. Thinking that mite solve it. but no, even on a freshly restored laptop its still not working.

Any help or guidance would be greatly appreciated

Heat maybe a factor
by Willy / July 12, 2009 11:50 PM PDT

Since you had this HD, it has become a target of wear&tear. The HD itself maybe within it tolerances but over time due to heat can drift its data. What that means, is the data is placed in such a way that under the same tolerances is it accessible. if outside of those tolerances, it will "drift" quite literally the data being(R/W) written gets spaced in such a way, it follows it own tracking outside of what was expected. usually, that happens only under heat stress or the electronics aren't as controlling as it once was also a factor of heat stress. A test of this maybe of new data easily accessed during its initial storage when HD was warm/hot and then when cooled, it becomes less so. Same in reverse where old data isn't so easily accessed during long system uptime but possibility quite well when system first started.

Many a ext. HD are passively cooled and may not use a fan, it just sits there getting warm, then hot if prolonged usage. Further, if just sitting there and its never "unplugged" from USB port any power-ON surge can damage the HD in some way. While it is very convenient it is only intended to used as back-up or working copy of your data. If you have warranty, use it, what you experienced is enough for the call. Also, you can use whatever diags. they provide via that HD makers support website -OR- the vendor's as well.

Hey thank you so much for the link Willy, and for the nice explanation.
It seems logical that iv been hit with the firmware issue, but its too late for just an update to fix it. (which I have updated now, and still same issues) I will contact Buffalo and take it from there.

Cheers again for all your help.
