Samsung T7 SSD Stuck in Read-Only Mode
Your Samsung T7 portable SSD has become read-only - you can see files but cannot modify or add anything.
SSDs entering read-only mode is a self-protection feature when the drive detects imminent failure. The controller locks the drive to prevent data corruption during failing writes. Your data is being protected, but the drive is failing.
Read-Only Mode Is A Warning
- ×Do not try to remove write protection via diskpart
- ×Do not format trying to make it writable
- ×Do not use Samsung Magician to 'fix' it
- ×Do not update firmware on the drive
- ×Do not use third-party write-protection removers
Why this matters: Read-only mode means the SSD is protecting your data from corruption. Forcing writes or formatting will either fail or destroy your data. The drive needs recovery, not repair.
Most Likely Causes
NAND Wear Protection
The NAND cells have worn out and the controller has locked writes to preserve existing data.
Controller Entering Safe Mode
Controller detected errors and entered protective read-only to prevent data loss.
Firmware-Triggered Protection
Firmware detected potential corruption and locked the drive.
Bad Block Threshold Exceeded
Too many bad blocks developed, triggering write lockout.
Safe Diagnostic Checks
These checks are non-destructive and safe to perform. Follow them exactly as written.
Verify read access
- Can you open and read files normally?
- Try copying files OFF the drive
- Copy your most important files first
- Don't worry about making it writable yet - save data first
Check SMART status
- If you can, run CrystalDiskInfo
- Look for 'Health Status'
- Note any warnings or critical values
- This confirms if drive is actually failing
Only do this after copying critical files off if possible.
When Professional Recovery Is Required
You should seek professional data recovery if any of these apply:
- •Can't copy files even though they're visible
- •Read speeds extremely slow
- •Some files won't open
- •You need complete data recovery
- •Drive is the only copy of important data
