Question

Iron

Suddenly, when Windows was running, everything from the desktop disappeared and shortcuts stopped working.
This disk had an MBR. I moved the MBR to another HDD. (I have GRUB)
And was able to boot.
Checked SMART. And here is such an error.
How dangerous are the values ​​and what can be done?

Answer 1

This attribute, part of HP SMART IV technology, means that after the data is transferred through the cache memory, the parity of the data between the host and the hard disk does not match.
The error is critical, indicating a possible breakdown of the device.

Answer 2

Definitely problems, if there is something important, you need not to pull and transfer everything you need to another disk. With this disk, you can try the following manipulations:
1. Delete all partitions
2. Recreate partitions with an offset, 500 mb at the beginning of the disk and leave empty at the end
3. Format
4. Fill the entire disk with something big, for example, movies to the eyeballs
5. Delete everything and pour again.
6. Use for not very important things like movies, etc. Because after paragraphs 1-5, the disk will usually recover, but not the fact that it will not die at the most crucial moment.
