Explanation
What this error means
CE-34335-8 means “no Hard Disk Drive detected in your PlayStation 4 console.” On boot the PS4 couldn’t see a usable internal drive. Either the drive has come loose, the drive has failed, or (after a swap) it isn’t seated correctly or hasn’t had system software installed yet.
Official reference: Sony support page for CE-34335-8
Diagnosis

| Hard drive loose in its bay | Very likely | Yes — reseat it |
| Newly swapped drive without system software | Likely | Yes — reinstall from USB |
| Hard drive has failed | Possible | Yes — replace it |
| Damaged drive caddy or connector | Rare | Sometimes — service |
Repair
How to fix it
Ordered easiest-first. Try the next step only if the error comes back.
-
Reseat the hard drive
Power off and unplug. Slide off the HDD bay cover, remove the caddy, and firmly reseat the drive into its connector before sliding it back in.
⚠ Opening the user-accessible HDD bay is allowed and doesn’t void the warranty, but unplug the console first and handle the caddy gently.
-
Check the drive is fully pushed home
A drive that’s a millimetre short of its connector reads as absent. Make sure it clicks fully into place and the caddy screw is snug.
-
Reinstall system software (new or wiped drive)
If the drive is new or was erased, the PS4 sees “no software.” Use Safe Mode > Reinstall System Software with the official full reinstall file on a FAT32/exFAT USB stick at PS4/UPDATE/PS4UPDATE.PUP.
-
Test with another known-good drive
If a healthy spare 2.5" SATA drive is detected and the original isn’t, the original drive has failed and needs replacing.
Escalation
When it's not your fault
Signs the problem is on Sony's side — or in the hardware — rather than anything you can change:
- The console was working, then was moved or knocked, and the drive popped loose.
- The drive is brand new — “not detected” just means it needs system software installed.
- A second known-good drive is detected immediately, pointing at a dead original.
Questions
FAQ
I just replaced the drive — why “not detected”?
A blank drive has no system software, so the PS4 reports it as unusable. Reinstall the full system software from USB in Safe Mode and it will be recognised.
Which drives fit a PS4?
A standard 2.5" SATA hard drive or SSD up to 9.5 mm thick. Reinstall system software after fitting it.
Did I lose my data?
If the original drive failed, data on it may be unrecoverable without specialist help — which is why PS Plus cloud or USB save backups matter. A reseat, by contrast, loses nothing.
