Question:

A deleted file on a modern SSD cannot be recovered although the same recovery succeeds on a hard disk. What most likely destroyed the data? / आधुनिक SSD पर डिलीट फाइल पुनर्प्राप्त नहीं हो पाई, जबकि हार्ड डिस्क पर वही रिकवरी सफल रही। डेटा को सबसे अधिक किसने नष्ट किया?

1.
The SSD's hardware encryption, which activates automatically on every deletion
2.
The Master File Table, which SSDs do not maintain
3.
The TRIM command, which lets the SSD controller erase unallocated NAND blocks
4.
Wear leveling, which hides deleted files in a secret reserved area

Correct Answer: The TRIM command, which lets the SSD controller erase unallocated NAND blocks

TRIM proactively erases freed NAND pages at the controller level, so deleted data is physically gone; on HDDs the magnetic data lingers until overwritten. / TRIM खाली NAND पेजों को कंट्रोलर स्तर पर मिटा देता है, इसलिए डेटा भौतिक रूप से समाप्त हो जाता है। Option (d) is the trap — wear leveling relocates writes but does not hide deleted content.
