External USB Storage Drive: critically low free space. The operating system cannot allocate working space for updates, caches or snapshots.

The distinguishing clue

Startup and applications slow while free space approaches zero.

Checks before an assessment

Cancel format or initialise prompts. Record the drive, enclosure and cable models, and whether the files have another verified copy.

Stop point: Format prompts should be cancelled until the file system and data value are assessed.

Workshop confirmation and repair

Device-level check: Test the enclosure, cable, port and internal drive separately without writing to uncertain media.

Targeted check: Measure real allocation, snapshots and large files before deleting data. If confirmed: Create verified free space and correct the process that consumed it.

Repair boundary: Repair the bridge or move the healthy internal drive to a compatible enclosure after data is secured.

Related cause to rule out

When health warnings, read retries or increasing bad blocks appear, also consider External USB Storage Drive: worn storage media before choosing a repair.

Checks after the work

After repair or replacement, check large file transfer, reconnect, sleep recovery and safe removal.
