I finally got around to ordering a Compactdrive 70x as a portable 
storage device. I wound up buying one with an "80" gigabyte drive (80 
million bytes, 74 megabytes, but who's counting...)

If anyone here is using a similar setup - a couple of questions.

First, the verified write mode does not seem to work at all with SD 
cards. (That's the mode where the drive reads and verifies each file.) 
It terminates after the first file with a verification error. It works 
fine with CF Cards though.  I have three brands of SD cards (SanDisk 
Ultra III, Transcend, and Dane Elec) and it works with none of these. Is 
anyone else using this mode with SD cards? I'm wondering if I got a bum 
unit.  Non-verified transfers from SD cards work fine, BTW.

Second - batteries. I bought this because it is supposed to work with 4 
AA batteries, but my NiMH batteries seem to work on a fresh charge for a 
short while, but if they sit in the device for just a few hours they 
can't put out enough voltage. The drive poops out with a #19 error, 
which means no hard drive present. Oddly, it's not the #20, "Bad 
Batteries" error. But fresh batteries (or using the power supply) fix 
the problem, and checking the batteries is recommended in the manual for 
this error.

These batteries are 1800 mAh Energizer brand, bout about 3 months ago. 
Granted - they have seen little use since I got them, and I'm in the 
process of completely draining and recharging them for a couple of 
cycles to see if that helps (over the last few months they have been 
charged, died with no use, recharged, a few times.)But I wonder if the 
Compactdrive can run off regular AA alkaline batteries or lithiums?  The 
manual states that it is intended to work with NiMH rechargeable, but 
never says not to use alkalines.  I also wonder if the large HD is 
draining more juice than a smaller drive would, and is dropping the 
battery voltage during power up and self test...

Any thoughts on these problems would be appreciated. I bought a fresh 
set of NiMh batteries and they are in there charging now, so maybe that 
will solve the battery issue.
