External USB drives not visible in OSX or XP

Hi, I change between 3 different IDE hard drives using my Macally external USB/firewire enclosure. Somehow all three of my drives are responding with a red (error) LED when I install them in the enclosure. Windows and OSX both don't see the drive at all either. I have checked under my computer/manager/drive manager to see if it is the mapping, but without luck. I don't think it is the master/slave pins (I have heard it could be that, but would be surprised). Is there any way to get these drives visible again? And if not, can I at least recover them to format them, as a worst case scenario?

Re: External USB drives not visible in OSX or XP

For the WD HDD, you need to set the jumper as Single or Master

For other HDD, you need to set as Master

Macally G-S350SUA power supply

  • I have the same Macally hard drive enclosure and I misplaced my power supply also. I used an old IBM Thinkpad power supply. These are common and cheap. The Macally enclosure states 12V DC input, and the Thinkpad PS is rated at 16V but it works fine. The plug and polarity are correct.

Hard Drive not mounting

Check the jumper on each hard-drive.

My guess is that the WD drive has the jumper in the "correct" position, for mounting inside an external case, while the other drives have their jumper set to an "incorrect" position.

Set the jumper to MA(ster), not to SL(ave), nor to C(able)S(elect).

USB Connection Problems

You say have a SanMax HD-338-CB USB/Firewire External HD with a 160MB drive. You then say sometimes I have to reboot Windows XP pro 2 or 3 time before I see the drive using a USB 2.0 connection. Fire wire is a different system with a different connector style- so it should not be in a USB port or a USB connector should not be in a Firewire device. Get you device and connections sorted The desktop display simply puts up a device it will not differentiate which USB or Firewire

you may take out the drive and connect it directly to your computer using it's IDE cable to check if the HDD still work. This will help you check if the problem was caused by the enclosure or if the HDD is already defective.
