Hello,
I have searched the forums and couldn't FIND any relative material, so any help appreciated.
I have 2 hard drives in my system. Everything worked fine for along time then one day after a reboot the 2nd drive is missing in MY Computer. Checked DEVICE manager and it is INSTALLED and enabled. Checked system settings and there was no drive letter assigned. After assigning a letter, rebooted and the same problem. The only way to get it working is to reboot, uninstall drive and reinstall it. Then it works untill the next reboot. Any help please. (jumper settings are correct)
Also ran hard DISK diagnostic tools with no problems found.

Windows XP sp2
AMD Athlon FX 3200
evga motherboard
1GB memory
evga 7800 gt video
Soundblaster Audigy 4 soundDoes the 2nd HDD have an OS installed on it ? ?Did you check the bios? Is the drive set to auto detect, manually added or off?the drive is in listed in BIOS as well as device manager. There is no OS on second drive. Thanks for the responses/ It worked well for wuite some time then wuit, so not an install errot. Suspecting registry type error but not sure.

Timsorry to mention, it's listed as auto detect in BIOS.
