ENTERPRISE HARD DRIVE - LOT OF 3

READ THIS FIRST

These are high-hour drives: between 5.7 and 6.3 years of power-on time

each. They are priced for that. What they have going for them is that every

media counter is zero and every one took a complete write of all 4 TB

without shedding a sector.

These are SATA drives (ALE640), not the SAS version (ALS640). They work in

any ordinary desktop, NAS or SATA HBA with no special controller.

Serial PBJG4VES

Power-on hours: 55119

Reallocated sectors: 0

Current pending sectors: 0

Offline uncorrectable: 0

Interface CRC errors: 0

All three: firmware MJAONS04, 512-byte logical / 4096-byte physical sectors

(512e), 7200 RPM, SATA 6.0 Gb/s.

Every figure above was read both before and after our wipe. Apart from

hours and at most one load cycle, nothing changed.

ABOUT THE ERROR LOG ENTRIES

A SATA drive keeps a log of commands that failed. PCK3ATRB holds 19 entries,

all of the IDNF type, the newest recorded at 49336 power-on hours - roughly

600 hours before it reached us. The other two drives hold a single IDNF

entry each. None of the counts moved during our complete write of every

sector, and reallocated, pending and offline uncorrectable sectors are zero

on all three, so there is no sign of a media problem behind them. We print

them because they are there.

HOW WE TESTED

Each drive was catalogued with smartctl before anything was written to it,

then given a full-length zero overwrite of every logical block with dd until

the device reported end-of-media, then catalogued again. The passes took

9h11m, 8h50m and 9h09m.

HONEST ASSESSMENT

High-runtime enterprise drives with clean media. Sensible uses: a backup

pool with redundancy, a lab or test array, cold storage you verify. Not what

we would pick as the only copy of anything important - no drive with six

years on it should be. Buy them for the price and the verified condition

data above, which you can check yourself the day they arrive.

DATA SANITIZATION

Every logical block on every drive was overwritten with zeros, running until

each drive reported end-of-media. We then read back the start, middle and

end of each and confirmed all three points contained zero non-zero bytes.

We hold a per-drive log for each one and all three record RESULT: WIPE

VERIFIED OK. All three arrive fully zeroed with no partition table.

WHAT YOU GET

Three (3) bare 3.5-inch SATA hard drives, the exact serials listed above.

No caddies, no trays, no rails, no screws, no cables, no adapters.

WARRANTY

Out of warranty. No manufacturer support.

SOLD AS-IS

Sold as-is with no returns. Everything we measured is printed above. If you

need a reading we did not capture, ask before buying.
