1. The reason you cannot see the drives’ on your computer is that more than one drive may have dropped off at the same time. To solve this problem, first go to the LCD panel on the front of the SSR-128. Hold the Enter key down until you get the main menu of the following:

CONFIGURATION
ADMINISTRATION
TOOLKIT
<cfg> <adm> <tlk> <nxt>

Push the square under the "tlk" and then Enter to get into Toolkit. It looks as follows:

SHOW DRIVES
DRIVE INFORMATION
CHANGE DRIVE STATE
<sho> <inf> <str> <nxt>

Push the square under the "sho" and then Enter to get into show drives.

2. You will now see a screen that displays the status of your drives. The first selection should show Channel# 0, which is Unit 1 of the two boxes that make up your RAID set. To get to the next channel, push the square under the "+" symbol until you see the number for the channel. Channel# 1 is Unit 2 of your RAID set. This is what your configuration should look like, depending on the type of set-up you have:

A Light RAID machine (10 disks)		A Heavy RAID machine (16 disks)
Channel # 0 St OOOOO-.... SD 00------ Press Any Key	Channel # 1 St OOOOO-.... SD 00------ Press Any Key	Channel# 0 St OOOOOOO-.... SD 00------ Press Any Key	Channel# 1 St OOOOOOO-SS...... SD 00------ Press Any Key

3. The "St" line will have either "O", meaning Online, "D", meaning Dead, "S" meaning Standby, a "." meaning drive not seen, or "-" which stands for the controller. Do not worry about the "SD" line. The "S" on the Heavy RAID unit is the hotswap disks that are on standby until needed to replace a failed drive. Write down the configuration, so that we can correct it later.

Lost Delayed Write Errors” on the SSR-128 can be encountered during file transfer, between the host and RAID system.

1. Check Cables, all external host cables should be less than 3 feet.

- Make sure no pins on the external connectors are bent

2. Check Host Adapter, make sure transfer rate is set to no greater than 20

3. Check Controller Configuration, in RAIDFX choose “Configuration” from the main menu. Go to “Advanced Functions” and select “Disk Side Parameters”. Make sure transfer rate is set to 10mhz for both channels.

4. Check Your Software settings. These errors can be caused by the software that you using to transfer your data.

5. Flush RAID Cache

- Power host and RAID unit down
- Unlock controller and remove controller card
- Remove jumper J2 from Battery Backup Module
- Remove memory SIMM’s and reseat memory
- Place J2 jumper back
- Lock Controller Card back into place
- Lock controller and reboot system (unit 2 first and then unit 1)

6. Check your NTFS Partition, if the problem persists; likely, there is a corrupt NTFS partition. You will need to back up your data and reformat the partition.

- Go to Disk Administrator and delete the partition
- Reboot the machine
- Recreate and format a new partition
