Hi All
I got a bunch of this hdd from deco from Movistar, Claro companys.
I trying to use on my computer, computer detects him, i checked with HDD Sentinel, and it appears there.
But, i cant delete partition, or create new one.
I tried with MHDD but he says: Drive not ready. and something with LBA..
The drive is connected via USB, i booted with a usb stick with command.com,
So, i readed a little and, add to config.sys the driver to load usb.
But when i boot keep appears 1/2 loading device, and stuck on 2/2...
So, i take out the primary hdd from the laptop, and put this one has primary. but the laptop says that cant load or something cant remember.
So im stuck..
Can anyone guide me, step by step, any god soul?
Thanks

Interesting clarification. Thanks for sharing.

This is not strictly true.
There is an additional ATA Streaming command set which is used for reading and writing uninterrupted data. These commands are only invoked when necessary. The normal read and write commands are still present as the default. In fact the latter are mandatory because an AV drive must still be able to write error-free file system information even though the AV content may have errors.

I read an article regarding that hypothetical issue about a year ago :
