Hmmm - you may be onto something John. Now that I think about it, the
only time I got the disk to actually appear as 250 Gig, was when I
pulled it out of it's enclosure and connect it directly to the PC. Then
when I put it back into the enclosure, that's when it reset to 2048
Gig.

And double hmmm, I bought this enclosure off eBay ... where the seller
said that the warranty would be void if I opened it up (not that I paid
any attention to that). Now I am wondering about whether I was
knowingly sold a faulty product.

Well only one way to be certain - time to connect it directly to the PC
again. I'll post and let you know how it goes ...
