hard disk coming and going

[koitsu]

Greetings!
I have an interesting problem. I have two hard disks most of the time when I power on but after say ten minutes or sometimes an hour the Maxtor dissappears! It´s not visible in My computer and and the software won´t start if I click an icon pointing to that disk.
Seems like the Maxtor is dying but could it be something else? Power supply?

Judging by the signature it seems that both hdd's are SATA right?
If the hdd's are ATA and are on the same IDE channel might wanna try and separate them. One on each channel.
If that doesn't solve the problem might wanna try a different power cable for the hdd.
And if that doesn't solve the problem, then it's possible that the Maxtor is dying.
Question though. After Maxtor "dissapears", and you reboot , does it shows in the POST ( if you are able to see the POST of course)?

After reboot it usually reads "slave not detected". the strange thing is that sometimes everything works ok for an hour, sometimes no disk at boot. Sometimes "secondary slave not detected. This is the samsung cd/rw...

most hard drive sites will have a file that you can dl to a flopy.

then it will tell you everything about the hard drive and run tests on it and the SMART feature on the hard drive will probally tell you info on why the hard drive is being lazy
