HDD access password


Hello!
I was wondering if there is any possibility to password protect *the general access* to the external HDD? I would like to avoid encryption.

So, generally the idea: HDD's electronics will not respond unless provided a password. I do not want one particular o/s block the access to this particular HDD. I want anybody taking the HDD anywhere and connecting it, being prompted a password before reading any information - e.g. about partitions which are on this disk. So something like "partition table ecryption". Or anything having similar effect.

The point is that I have quite many partitions and encrypting all of them would be too much trouble (I'd have to give over 6 passwords to boot and make some simple operations).

Thank you for help!

P.S. Partitions are of different type, ext3, ext2, fat32, ntfs etc.

Best regards,
Theriel

Unless you design and build custom drive electronics, you're out of luck. You can't prevent access to a drive, unless you encrypt it. Things like truecrypt and pointsec do this, to prevent unauthorized access to drives in the event of loss/theft.

Heh, OK so it seems that I'm stuck with encryption.

Would you be so kind and tell me which one to choose: TrueCrypt or LUKS? I tried Google but except for one strange test (showing that LUKS is 3x faster) I haven't found anything more... Any differences in features?

Best regards,
Theriel

The only hard drive I have seen that requires a password pre-access, is the Seagate Momentus FDE (Full Disk Encryption) Hard drives, that are available in some Dell Laptops that have the Hardware/Firmware necessary to support those drives.. (they do work rather well btw..)

The Seagate® Momentus® 7200 FDE drive delivers up to 320 GB of secure digital storage using Seagate Secure™ technology, which is designed to prevent data breaches due to loss or theft on the road, in the office and in the data center. Seagate Secure technology also enables secure disposal and repurposing of drives. Additionally, customers can order the G-Force Protection™ model (ASG) and get additional robustness built in.

Advanced security firmware allows for pre-boot authentication in the form of biometrics, passwords or smart cards. The hardware-based encryption engine delivers security without the overhead—no processor utilization, no time delays. You get transparent security without the hassle.

It appears LaCie released an external unit that requires biometric access, but I know nothing of them..

Mhm, thank you.... could then sb suggest which encryption to choose: TrueCrypt or LUKS?

After some research I discovered only these two differences:
->TrueCrypt provides deniable encryption: entering different passwords gives different levels of access to the data. Sounds interesting if you want to have some data hidden and impossible to be traced.
->TrueCrypt doesn't have any recognizable header in its partitions. LUKS does. Hence somebody knows that: "hey, here there is an encrypted partition!".
