I am planning to do a complete format on my computer. My HDD (which everything is located) is encrypted with BitLocker. A few months ago I tried to manually decrypt the drive to not cause any error before format but it literally took ages to even decrypt. Since I don't care about the data, is it OK for me to format a Bitlocker encrypted drive? Will it cause any problems or errors?
How are you reinstalling windows? Are you going to be using a recovery partition or discs? – Will M – 2017-04-22T19:19:17.400
Modern rotational drives tend to have a throughput in the 50-100 MB/s range during purely sequential I/O. (Seeking can easily drop this to a few hundred kilobytes per second in the worst case, if you are IOPS-bound doing I/O on single sectors.) Thus a 4 TB drive will take at least 80,000 seconds (or thereabouts), which is a shade over 22 hours, to process. Is this in line with your relatively vague "ages"? – a CVn – 2017-04-22T20:11:50.823
@MichaelKjörling yes it is. – Eren Kara – 2017-04-23T10:47:51.803
