Secondary hard disk unseen by PC


Thread Starter
Dec 23, 2006
Hello everyone,
I am having problem with my PC. It has two physical HDD: one (C: ) for system and documents; second (E: ) - for movies, photos.
Few weeks ago, E: started to behave strangely. Initially PC saw that disk, but when clicked - "no such disk", some time later I saw message that "Disk is not formatted". I did not take any action.
PC did not experience fall or any kind of physical damage. I have legal antivirus software installed and do not download any pirated software.
E: did not have any accesbility problems for several yes (since PC is several years old).

Recently tried to run Chkdsk, but it does not see E:

Since I am at work now, cannot post any log of that disk. Any help on how to try to extract datya would be really appreciated.

I'd try to run a diagnostic on the hdd. Most manufacturers have their own utilities for thet.
If not you can download Seagate's "SeaTools". Create a bootable USB or DVD then try to run to see whether the disk has issues.

Also try to move to a different port - if possible - on the board. As well as trying a different cable.

Click HERE to download the bootable version for USB.

All drives fail; it is only a question of when your drive will fail. This is just one reason why we stress backups so much.
The above is good advise. Reseat both pw and data cables. If possible, use a different sata port on the motherboard and a different sata cable. Run the mfg's diagnostic on the drive. Be sure to run both the short and long tests.
