Can Truecrypt encrypt a full hard disk/drive , when/if incase it contains some 1) read/write errors ? 2) bad sectors ? Before or even if after , they are fixed and recovered by windows chkdsk etc...
Details : I’ve an all Empty Seagate Barracuda 7200.12 500GB HDD , which I m trying to encrypt by Truecrypt, I m using it as an external HDD via USB 2.0 connection , ( by USB to ATA/ATAPI bridge , as it says in windows taskbar notification area..as it’s USB to SATA connection) The problem I m facing is HDD is detectable by my windows 7 normally for hours like , and when I start encrypting it by Truecrypt , It encrypts it for a while like 41%-50% till around , and then suddenly Truecrypt Volume creation wizard says – “The Device is not ready “ , and then HDD isn’t detectable by windows 7 after that , ( as it ejects ) , which otherwise performs normally and is detectable…
I thought might be there can be an error on drive or bad sector…
So Then I ran a couple of Diagonistic tests too to check…
1) Windows Chkdsk reports - No errors and 0 bad sectors
2) Seagate Seatools “PASSES” it in all tests , from Short generic to Long generic test…
3) Ariolic disk scanner , at one scan , reported 62 read errors in one red dot block while scanning In its GUI interface rest all were green , and then stops the scan any further…
4) I’ve not given Spinrite yet a try…
Now I can’t make out What cud be the problem , and as though Why I can’t encrypt it… (Note : Also the disk is supposingly New and for it has been Replaced by Seagate in exchange of my earlier Seagate hard disk which was making noise , so they made a replacement under warranty ) This one works normally, but doesn’t lets me encrypt !
If it's got bad sectors, throw it out. In Windows, make sure you run
chkdsk
with the/R
switch (e.g.chkdsk A: /R
). – Breakthrough – 2011-10-15T01:43:12.593@Kaustubh It should still encrypt the good part of, like a normal drive., Here are the potential "gotchas": NO3. The full encryption option will not work, just do 'part of', your drive is unlikely to be 50% bad sectors-maybe just in the middle, try 2 volumes. – mic84 – 2011-10-15T06:48:34.353
@Breakthough ran chkdsk! before FDE nothing no improvement with encryption , no bad sectors are reported also by chkdsk /f/r .. already did it couple of times before running FDE – kaustubh – 2011-10-15T06:58:05.127
@mic84 i've reuploaded the images to different imagehost , now u can see...what it's like.. http://i.imgur.com/HAMQe.jpg http://i.imgur.com/1ZSXO.jpg http://i.imgur.com/82Ak9.jpg
