HDD hard drive sectors problem?
Good day community,
I have a question regarding my HDD hard drive.
For a few days now, the HDD control LED on my motherboard has been permanently lit. While checking all of my hard drives, I noticed that one of them had floating and uncorrectable sectors. After shutting down the hard drive, the LED went out. The drive contains approximately 2.75 TB of sensitive data. The drive is now back in service, and the control LED is lit again. The drive does not appear to have lost any data.
Should I just let the disk continue running or should I evacuate the data to another hard drive?
If so, could the hard drive still be repaired?
Thanks for the help in advance 🙂

No, you can’t, but you can watch it. If you have a backup and regularly look at the SMART values every 1-2 months, you can continue using the disk with the few sector errors.
I myself have a 12TB record that reports a few newly assigned sectors in “05” for over 1 year. First it was 0x08 now we are at 0x10 (i.e. 16 sectors in decimalwriting mode)
Your 0x20 therefore corresponds to 32 sectors or 4 EF sectors (new panels combine 8 sectors into an EF sector)…
It is more strange that these sectors are not correct – this is a worse sign, so if they occur under “new assigned” (05). So you should be more careful.
If you have a backup, you never need to fear data loss! Just mentioned by the way!
Thank you.
A hard drive is always bigger than the one shown. The surplus is so-called reserve sectors.
In the past, you could not build panels that are 100% error-free. There it was necessary to tap a table from the plate (later car recognition during formatting) which the system says which sectors were not allowed to be used.
Since the early 1990s, fault-free plates came.
Sometime after 2000, the memory density was pushed to the physical boundary so that there are often broken sectors. It secretly exchanges the hard drive for reserve sectors.
If the reserve sectors go out, the damage will appear as soon as possible and the system will notice which sectors are “tabu”. This proves there’s a damage that’s getting bigger and bigger. For a manufacturer will never deliver a record where more than half of the reserve sectors have already been consumed.
So make a backup as soon as possible and throw away the old plate or mark and only use it for experiments.
P.S.:
Here is a picture of a very old plate.
The table above is the “Bad Sector Table” that you had to tap into the system.
Bad tongues claim that the plates were only so large that they had enough space for the Bad Sector Table.
Thank you.
No backup? No pity!
Is that enough as a wink with a stake?
Finally, this fact has been constantly underlined over 30 years. 🤷
Or else: You need to know what your data is worth.
A mimimi! My data is fussy because I No Copy had!” does not create empathy anymore.
Short and for lay: No.
If the first sectors are damaged, this will continue.
How fast you can’t say – but it will.
Thank you for the clear answer! The data is already evacuated.
