Spontaneous external hard drive un-mounting

[stevenew]

Hi everyone,

Thanks for all this info, its all really useful.

I notice that the first enclosure that Daniel provided the link to, also uses a Oxford chipset, which everyone tells me is the best, so if that enclosure is problematic, just finding an enclosure with an Oxford chipset (like the one I was thinking of buying) does not mean a stable enclosure.

This sure gets tricky, I think I may give the company I linked to in my post above here in the UK, a call and see what their reaction is to these issues.

Thanks

Steve

Some of the companies are helpful with this common problem.I bought 5 Macally enclosures last year:
Model# phi-s100sua
they run sata fw or USB and they were well reviewed and cheap($35each)
After 6 months I thought 2 drives were going south, they were both fine but after sending back the enclosures Macally immediately sent me 2 new enclosures without even checkingthem, so I think this issue is very common. Previously I had Firmtek SATA enclosures that I had issues with,simply replacing the wall wart solved the problems.wall warts fail all the time.

Just for the record: the very same erratic enclosure did work fine with 10.4.11, but was a nightmare with 10.6.8.
The support men said all was fine with both OS at their place. I doubt...
