Windows 7 Dropping drive letter on SATA drive


New Member
Win7, build 7100

IBM x206 server with 74GB primary (boot) SATA drive on channel 1, and 640GB SATA drive on channel 2

The 640GB drive "disappears" from view after reboot. It drops the drive letter and I have to manually reassign the letter and the shares.

Drive is formatted as NTFS, not marked active.

Thanks in advance for any tips...

Each time I reboot. I can see the disk in the disk management console, but the drive letter and shares are gone.

Just that one drive tho... The primary (C:) drive is fine, as is an external USB drive.

Appreciate any thoughts...
