help with external drive!!

Sorry if this sounds simple, but can you check to make sure they are all put in the enclosure correctly and all of the connections are stable and aligned?

 

When you installed the HD did you make sure that the jumper settings were correct? This probably isn't your problem but I would check it. Also it could be a bad enclosure. Which enclosure and HD do you have?

Sorry for the questions but could you give the hard drives that your using. What interface (SATA or ATA?) I'm assuming ATA. You could have bad hard drives possibly.

Another option you might want to try is to reformat it and also scan the HD using TechTool or something similar. Also on your USB+FW enclosure have you tried both usb and firewire and do they give the same results?

Edit: the Adaptec has an SATA internal interface and I couldn't find the Ion enclosures interface.

 

who is the harddrive maker or did I miss it?

As far as it goes, once both drives were plugged it, what format did you use to format them?

I have a 320GB, 160 and a 250GB and coming soon a 500GB HDD coming and the 1st three, work just fine with my PMG5. 2 are via Firewire and last is via USB. Ive had 0 glitches. Infact, FCP is set to cache on my 320GB and i edit right off that and it works flawlessly.

 

I've never had any problems with mine as well. It sounds as if your enclosures are faulty. It also depends if your HD meets the requirements of your enclosure, but usually in rare cases.

The Adaptec enclosure you have supports 1.5Gbps & 3.0Gbps SATA drives (got this from newegg's specs). Make sure you have this type of HD.

I'm not sure what else to say since it would be helpful to know all the specs of your setups. I would try returning your Adaptec enclosure and getting something else possibly.
