USB Key (Imation 4GB) freezes all Macs

Heya

I got 2 USB keys (4GB Imation http://www.imation.co.uk/products/flashdevices/flash4gb.html ) and they have been causing major headaches (and wonton destruction actually)

With my PowerMac Dual G5, attached to front USB port, and 2 different PowerBook 12inch (one 1.33Ghz, and one 1.5Ghz) all with 10.4.7, it causes Finder FREEZE after a minute it is inserted, and in the case of the 1.5Ghz 12inch, after 5 minutes, it cause a KERNEL PANIC.

Afaik, with 10.4.6 there were no problems (I only remember using it a few times before 10.4.7 came out and I had no problems)

I insert the drive, it mounts, and after a minute or so, the Finder hangs. Sometimes, if I remove it, everything goes back to normal, but mostly, I get a TOTAL SYSTEM FREEZE (only way is to cold reboot).

I managed once to reformat one of the USB drives into HFS+ Journaled and it still hung.

I used it with a dozen other PCs and never had a problem.

Help!?

Dual 2.7 G5, Mac OS X (10.4.7), 2GB, 2x400GB, nVidia 6800

Hi, Z.

1. Have you contacted Imation to see if they've had similar reports from other users of Mac OS X 10.4.7?

2. Have you tried a different brand of USB Flash Drive (UFD)?

While it's possible some change in 10.4.7 may be causing issues with the built-in firmware of the Imation UFDs you cite, I think it unlikely. However, if others have been experiencing such problems with those same UFDs, contacting Imation would be a good way to find out.

Good luck!

I have the same thing happening on my iMac. Not only with an iMation (1GB) thumb drive, but also my Kensington 1GB drive, and a 2GB memory card in a USB reader. All used to work fine, all still work fine on a PC (likely my next computer, at this rate...), but all suddenly causing this "freezing" problem on my Mac.

And before anyone asks...
- no, I haven't made any recent hardware or software changes
- yes, I have removed all USB devices except the keyboard
- yes, I have tried all of the USB ports
