4.0 out of 5 stars good on USB, but unreliable on eSata, February 19, 2011
Verified Purchase(What's this?)
This review is from: Apricorn Aegis Padlock Pro 640 GB USB 2.0 and eSATA 256-bit Encrypted Portable External Hard Drive A25-PLe256-640 (Black) (Personal Computers)
I love the Apricorn padlock drive, I have two; one 'regular' 640 and one 'pro' 640.
Both perform with acceptable speeds for an encrypting device.

However, I have never gotten the eSata interface to work reliably. I would be interested to read comments to the contrary. Anyway, here is what I mean by 'unreliable':
* device is recognize just fine.
* device transfers files to-and-fro
* BUT, when I hash the file on the source and destination, they are different. This doesn't happen when using the USB interface. During this test, I transfer ~100GB files.
* this was done on a different machines, with different eSata interfaces, with the same results
* this was done with a different eSata external drive (actually a KingWin ezDock), with success

I can only conclude that the eSata capability is defective in some way. It would be nice because it transfers (albeit with errors) at about twice the speed of USB. But, at least the USB is reliable...

BTW, for those having trouble with getting the eSata to work at all, I use WinXP 32-bit, and I have to plug it in before booting up, with the auxilliary power cord, and have to shut the computer down before removal. I.e. not hot-swapable. Also, I enter my password during the bootup process before it gets to the OS loading. Maybe this helps someone.

Also, for those having trouble 'safely removing' (from USB), make sure that there are no locks on the drive, i.e. no open files or even directories (e.g. no explorer windows, or command prompts). Then you can safely remove. Well, you may have to try more than once to wait for caching to finish writing, but it will happen (this happens even on other drives/thumbdrives). If you don't have the 'safely remove' icon in your tray, you can use
%windir%\system32\rundll32.exe shell32.dll,Control_RunDLL hotplug.dll
to bring up a similar but more detailed UI for removing.

In your journal that the 2.0 (and maybe earlier versions) are "PIN controlled hard drive with data obfuscation". Since I don't have the crypto-background, I'm not sure that I understand why it's not secure. I very basic terms, I understand your statement of data obfuscation but I'm not sure how they could market the device to be AES-128/256 encryption?

On a different notice, have you gotten the itch to take apart the "USB 3.0 variations" of the padlock to see if it is better at encryption?
