Best way to recover data from failing drive?
My 5TB external 2.5" Seagate BUP Portable HDD has 4% health and I had errors trying to copy some files off of the drive. SnapX1 20240409_224938019 HDSentinel.png My plan is: (1) Make a "forensic sector copy" clone of the drive using Macrium Reflect (i.e. copy all sectors whether used ...

Re: Can other programs read or be notified of the HD Sentinel health status?
Thank you! I'll pass that info to the developer of WinCatalog because that's where it would be useful to me. But I have no idea how many of his users might have HD Sentinel installed or would install it if WinCatalog had that capability.

Re: Separate Write and then Read Test vs WRITE + read test combine
Interesting. I started running separate sequential write (random data) and then read tests because I wanted to see the separate write and read graphs for my new nvme drives to see their behavior but didn't realize that's not as robust as the combined test. (Not really critical for a new drive with n...

Advice for buying used hard drive? Sellers reset everything to zero.
Any advice for buying a used hard drive? How to avoid any tricks that sellers use to hide known problems? Are refurbished drives safe or likely to have recurring problems? Locally, here in Indonesia, there are many 100% health drives for sale that are 9+ years old with zero or under 100 hours. I hav...

Can other programs read or be notified of the HD Sentinel health status?
In preparation to dedupe my USB drives, last year I catalogued all of my disks with WinCatalog. Now that I finally get back two the project, two of my disks are failing, with 10% health! Both a source disk and one of its backups. Although I surely had Hard Disk Sentinel installed, I didn't notice an...

Re: Lexar NM790 4TB nvme no self-test & highly variable speeds. ok or not?
I ran three more tests of read only (sequential, butterfly and random) that all consistently ran just below 3000 MB/s.
I partitioned 93% since I don't know how much overprovisioning is built into this drive, and now to start filling it as a data drive.

Re: Lexar NM790 4TB nvme no self-test & highly variable speeds. ok or not?
FYI, After the reinitialization test on 4TB, I was surprised that the drive was partitioned but I assume that's normal.
But easily changed back to a single GPT drive.

Re: Lexar NM790 4TB nvme no self-test & highly variable speeds. ok or not?
12. Reinitialization test: Took 12 hours Started at 260 MB/s and later dropped to 80 MB/s (read) and 240 MB/s (write). Screenshot (1623).png Screenshot (1625).png It passes again, so I guess that it's working ok despite the earlier problems with tests 5, 6 & 7 (above). In comparison, my Samsung ...

Thank you, So a reinitialization test deletes the partitions. I missed that. ok. No problem then. Good. Thank-you. FYI, By "reinitialization testing on partition 3 only" I mean using the test configuration to only test the blocks that correspond to that partition (i.e. 7230 to 9999) (I ret...

Trying to understand Weak, Damaged & Bad Sectors
Non-critical questions to aid my understanding: (Q1) What's the difference between a damaged sector and a bad sector? (Q2) After a repair or re-initialization test, there should be no weak sectors because they have all been reclassified as good/damaged/bad? (That's why tests don't state the number o...

Safe to use repaired drive? 6% Health (had semaphore timeout

When connecting a 6+ year old MyBook 4TB USB 3.0 WDBACW0040HBK-H1 3813B with Hitachi drive that had not been used for several years, it quickly reported 2224 weak sectors.

Re: Hard Disk Sentinel Software Worth Buying?
Absolutely worth buying! I have had Hard Disk Sentinel for years. The report window appears every time that I restart but everything is always good, so I almost ignore it. Until I was consolidating my old backup USB drives and one 2TB USB HDD reported 88% health and I "panicked." Backed up...
