I use electrical tape for such things. Just wrap it around the cable and then tape it to the tower. It is pretty safe and is easy to remove.

I am using a software package called Readsoft Forms. I create form definitions for different surveys using this software. when I change to a different form definition to scan I sometimes get an error...


Please try USB connectivity instead of SCSI. It is lot easier and unlike SCSI, there is no sequencing required. (With SCSI, you need to start the device before you start the Computer). You can switch on the scanner when you want!

Getting the following error repeatedly: A parity error was detected on \Device\RaidPort1. Source: adpu320 Event ID: 5 Any help would be greatly appreciated...


Any "Parity Error" is from a communication error on the SCSI bus, and it's bad! Errors are a way of life, and the SCSI transceiver has failsafes to fight them, and one of these is parity. Consider it extra data that the controller sends when you transfer data to your hard disks. Once there, the drives transceiver does a simple ccheck and verifies that the parity is correct. If not, a Parity Error is generated.

99% of the problems surround the SCSI bus itself in the form of a damaged SCSI cable, loose terminator, or a bent pin on a SCSI connector (latter being most common). This error is more apparent after moving the SCSI devices, resulting in unplugging and then replugging the cables back onto the Targets (HDD, CD/DVD ROM, printer, etc.) or back onto the Host Bus Adapter (HBA - the 29320 in your case). Check ALL pins. You can try to straighten the pins, otherwise it's time to replace the cable. REMEMBER that terminators are a must and can also cause Parity Errors if there is no termination present on one end of the bus or the other.

Best of luck

I want to retrieve data from an old 50-pin hd from my old mac. Anybody got a solution?


There are two ways of retrieving data from a SCSI hard drive.
1. Connect the SCSI hard drive to a different SCSI connector on the same data cable, make sure this hard drive has a different SCSI ID from the first hard drive or other SCSI devices in your system. When you boot up your MAC you should see the second SCSI hard drive, You can then copy off your data or remove the redundant files and keep the old hard drive in your system as a 2nd hard drive.
2. Connect the old SCSI hard drive to a SCSI USB hard drive adapter. Then connect it to the USB port on the MAC and you should see this as an external hard drive.

SCSI Hard drives


i think you have two connections to SCSI drives not one to ide and one to scsi. anyway, if you have a SCSI controller card, you only need to connect do SCSI drives. only.

Could be a SCSI termination issue. Try changing the SCSI address number on the scanner to a different one and make sure the chain is terminated properly. If there are multiple SCSI devices in the chain, disconnect all the others until you are sure the scanner is working then slowly add the other devices to the chain making sure everything works as each device is added.

My exterior Apple CD 600e will not show on the desktop of my Maci


As I recall, this is a SCSI device. Like many electrical connectors, SCSI connectors can develop a light corrosion which can keep the signals from being transmitted. The easiest way to clean such light corrosion is to shut down the Mac & power down *all* SCSI devices in the chain. Then gently unplug & replug all SCSI connectors. This will scrape off much of the corrosion & usually results in connectivity being restored. Be sure to unplug and replug the SCSI terminator attached to the last device in the SCSI chain. Restart by powering up the SCSI devices and finally restarting the Mac. Good luck!

Your SCSI card sounds like it is either loose or knackered, look inside your machine and make sure all connections are connected as you would expect on the SCSI card and any cables, if all seems ok then beg borrow or lend another SCSI card from a friend or another machine try that if all is ok with the other card then your problem is sorted, knackered SCSI card.
