EEPC 5.2.3 removal stopped with hard reboot, asking for help

Dear community,

we have a problematic notebook / Harddrive (1 encrypted partition only) on Dell Latitude E6400 with McAfee EEPC v.5.2.3 that suddenly freezed in Windows, during "EEPC removal" process, started via

McAfee Manager.

This occured not directly on beginning , but in middle of decryption phase.

After this, the machine does still have Pre-Boot Client installed, but it hungs up "freeze", on windows logon screen.  Doesn't matter if we boot  windows normal, or with recovery options .

So what we have now is, a suitable Safetech USB Drive, a .sdb File for this machine  and a Screenshot of "Crypt List". (see attached)

As I understand this cryptlist,  there's not whole drive encrypted any more, since start sector is not 63 any more?


When we try to force decrypt  remaining sectors from 4186305 with sector count 484205760 , we run immediately in error message: Encryption Failue: 0xe0020007 (see attached)


This error 0xe0020007 means;  Error reading disk sector ???

If we try to decrypt some sectors in this range  in Workspace (for testing purpose only) notebook crashes and reboots again.

What other options do we have?

Is this harddrive definitely scrap?

Thank you for any help.

did you checked hdd health by running hdd daignos

do you have another disk on the same system ? as in snaps you are trying to decrpyt Disk1 (are you sure its not  pen drive ?)

what are the HDD option you have selected in BIOS ? like AHCI/IDE/Compatible/SATA Native Mode

what if you plug this hdd on another system and try to force decrypt ?

I forgot to mention that the HDD is already on a identical LATITUDE model.

We'll check if bios ATA Modes could be changed.

As we can see in disk Information screen, I'm almost sure, this is correct drive 1 (Machine ID, SBFS sector information...), that's partially encrypted, isn't it?

when we try to view disk number 0 we receive nothing special:


We'll try to Diagnose the HDD now, with corresponding tools as well.

what if you use wintech instead ?

you should not have used the force option - now the disk information is unreliable, we no longer know what's encrypted and what's not. 😞

Let's hope safetech didn't do anything at all.

As others said, use WinTech, and do a normal removal - if the pre-boot is still there and all ok. probably it will just decrypt fine. It might be worth looking around the sectors you tried to decrypt though and trying to work out what state they are in - put them back to encrypted if needed so the region list is correct.

Thank you for your answers,

but we assume now, that harddrive is the problem itself.

Dell self tests mention that HDD self-test is not successfull.
