Seagate Rosewood – Small, thin, light, and unreliable?
In early 2016 Seagate released an ultra-thin, light, high density hard disk drive targeting the mobile or portable data market. The hard drive was marketed as the lightest, fastest, and most power efficient ultra-thin drive available. This hard drives’ comparative flimsy construction however leaves it susceptible to failure and data loss.
Weighing in at only 3.17oz and 7mm thick this drive really is a featherweight in the hard drive space and the more common drives come in either a 1TB (ST1000LM035) or 2TB (ST2000LM007) variant but can include the following:
- ST1000LM037 – Seagate Secure
- ST1000LM038 – Seagate Secure FIPS (Federal Information Processing Standard)
- ST2000LM010 – Seagate Secure FIPS
- ST2000LM009 – Seagate Secure
These ‘Rosewood’ hard drives can be purchased separately but are generally bundled as the internal drive component of many popular OEM portable external hard drive and laptop products including:
Lacie – Rugged Mini LAC301558/LAC9000298, Porche design USB C including Thunderbolt
Latest Seagate expansion – STEF1000401, STEA1000400, STEF2000401, STEA2000400
Latest backup Plus – STDS1000900 & STDS2000900
Maxtor – HX-M101TCB/GMR & HX-M201TCB/GM
Laptops – Many, many new laptops contain these drivesThe larger capacity drive also boasts impressive 1TB SMR platters running at 5400 RPM with both drives offering a very nice 128MB cache accessible through a SATA 6Gb/s interface port.
Below are a few other stats taken from the Seagate spec sheet:
Performance – 140MB/s with a spindle speed of 5400RPM
Reliability – 600,000 load/unload cycles, Ramp loading head rest method and a 2-year warranty
Power Management – 50W (2TB) or 45W (1TB) idle
Physical – 7.0mm height, 69.85mm width, 100mm depth and a 90g weightAll this sounds great right? Well on paper yes, but these drives have been an epidemic in the data recovery world since they were launched. We at Datlabs has seen hundreds of these devices through our doors and unlike other new drive the R&D learning curve has been steep.

Data Recovery Options and Problems
To get a quick idea, we performed a report on our internal database which we use to track all cases we receive. Our report detailed we have received 122 Rosewood drives this year so far – approximately 20 drives each month. This is an increase on 2017 but last year also was a very busy year for this model of drive. Thankfully with our recent developments in methods and procedures Datlabs recovery rates for Rosewood drives has now improved markedly. but this was not always the case as any honest data recovery company will admit, from the very beginning these drives challenged even the best data recovery technician from the locked diagnostic port to the lack of internal space making a HSA (head stack assembly) exchange very difficult using typical tools and techniques. Below we go into a little more detail as to why these drives are difficult for the data recovery industry and why you should maybe avoid trusting these drives exclusively with your critical data.
