Where to begin? The error message: "G:\ The system cannot find the device specified"
The sequence of events. I have loaded four new 1TB drives into an external Arcea-5020 enclosure. With a SanDigital (Silicone Image 3124) based PCI-X card in an Intel SAE7501br2 server board (dual Xeon). The 5020 has undergone many configurations of raid sets and volumes, all with the same result. For simplicity sake, it is now in JBOD mode.
While in Windows 2000 Server Disk Managment, the server will "see" the drives as 931.51GB, you can write the signature, you can create a partition, you can format the parition, the disk manager will report the drive is "Healthy", and that's it. If you try to browse the drive you get the error message above. (The system cannot find the device specified)
Note it says 'device specified'. If you do a properties on the disk you see what appears to be normal address of the device depending if you are in USB or eSata mode. ie: SCSI (Port: 5, Target ID: 0, LUN:0) the next is SCSI (Port: 5, Target ID: 1, LUN:0) and so on.
If trying to access G: through Windows Explorer the error is different: "G:\ is not accessible. The folder was moved or removed."
If trying to access at a command prompt you get: "Invalid drive specification"
This happens wether the drives are using esata bus or USB interfaces.
The 5020 is running the latest BIOS 1.46 in base mode. The server board has a BIOS (P16) which has LBA support. The server registry has been updated with EnableBigLba key.
The event viewer shows an ARRIVAL notification for the removable device:
Received a device interface ARRIVAL notification for device:
I belive the 5020 is working because all apears to work normally when connected to an XP box.
Please let me know if you need any more details.
