Are the electromagnetic fields and waves generated by a large 29" CRT TV (turn ON) and Desk Fan (turn ON) at a distance of 2cm from a 2.5" HDD (turn ON) sufficient to penetrate the HDD and cause interference in the arm and head movements, as well as read and write errors?
and platters interference?

How old is the hard drive? What size is it and how much storage is on it? Do you know the speed at which it operates? Use the link below for more information.
2010 or 2011, 500gb or 1tb
In conclusion, the electromagnetic fields generated by a 29" CRT television and a desk fan, even when operating very close to a powered-on 2.5" hard disk drive, are not strong enough to penetrate the drive or interfere with head movement, servo control, read/write operations, or platter magnetization. Hard disk drives are built with metal enclosures, high-coercivity magnetic platters, and closed-loop servo systems that are not affected by weak, low-frequency electromagnetic fields from common consumer devices. If read/write errors or drive instability occur, the cause is far more likely related to drive wear, mechanical vibration from direct contact, heat, power issues, or internal hardware faults rather than electromagnetic interference.
Since the drives are around fifteen years old there’s a good chance, they may be going bad. I have had to have drives replaced over the years.
I prefer Solid State drives, but my desktop has both an SSD and HDD. My two WDMYCLOUDS both have HDD. I have a laptop that has an SSD.
I have a 2.5" HDD + USB enclosure and CrystalDiskInfo shows good health.
I have files on this 2.5" HDD. If I delete some files and copy new files onto the HDD, could the remaining files that I didn’t change be corrupted or lost because of the erasing procedure, copying some files that were on the drive, and adding new files?
For example: I have 300 old files on the 2.5" HDD. I deleted 50 files and added 50 new files. Could some of the remaining 250 files suffer corruption or loss due to the procedure, stressing the platters with the erasing/copying process?Read
No, deleting 50 files and adding 50 new ones will not corrupt the other 250 files on a healthy drive. Deleting just frees up space and new files are written to available sectors. It does not disturb existing data. Since CrystalDiskInfo shows good health, your files are safe under normal use. The only real risks are sudden power loss or unplugging the drive during transfers.
is secure for old files in hdd not degrade?
Old files on an HDD do not degrade just because they’re old. If the drive is healthy and stored in a normal indoor environment, your data will stay fine. What causes loss is drive failure, heat, moisture, or physical damage. Just check the drive health occasionally in Windows and keep a backup to stay safe.
